Казалось бы, что сложного в написании телефонного номера? Сложного, действительно, ничего нет, но есть нюансы. Правильно написанный телефонный номер увеличит шансы, что клиент дозвониться до вашей компании. Ваш текст, сайт или буклет будет выглядеть более профессионально, если телефонный номер будет написан правильно.
С чего начинать номер: +7 или 8?
Запись российских номеров правильно начинать с кода +7. Это международный код России. Если номер указан с префиксом +7, то по этому номеру к вам могут дозвониться из-за границы. А префикс 8 — это атавизм, оставшийся со времён СССР. Это был код выхода на междугороднюю связь внутри страны. «Восьмёрка» и сейчас продолжает работать на стационарных телефонах, но если вы хотите увеличить шансы, чтобы к вам дозвонились, указывайте в телефонном номере только код +7.
Как группировать цифры номера? Использовать пробелы или дефис?
Цифры в телефонном номере группируются по две справа налево. Если в первой группе цифр телефонного номера одна цифра, ее допустимо объединять в одну группу со следующими двумя цифрами. Например: 591-85-60; 445-02. Телефонные номера с удачным расположением цифр допускается оформлять иначе: 222-8-222. Группы цифр отделяются друг от друга дефисами, но допускается отделение пробелами.
Нужны ли скобки?
Строгих правил по поводу скобок нет. Здесь можно руководствоваться тем, что в русском языке в скобки заключается дополнительная информация, поясняющая основную. Код города можно считать поясняющей информацией, ведь часто можно обойтись и без кода, если номер предназначен для использования только внутри города. А вот для мобильных номеров код оператора совершенно необходим, так как без этого кода дозвониться не удастся.
Мобильные номера: +7 922 670-45-10
Городские номера: +7 (351) 765-43-21, допустимо: (351) 765-43-21 или 765-43-21.
В Москве существует два городских телефонных кода 495 и 499, поэтому правильным будет указывать московские городские телефонные номера так же, как и мобильные номера, то есть без скобок: +7 495 555-50-50, +7 499 444-45-50.

Мы привыкли записывать телефонный номер, начиная с восьмерки. Поэтому когда где-либо требуется записать или ввести на сайте номер телефона в международном формате, то сразу в голове масса вопросов.
Подробно рассказываем, как набрать номер телефона в международном формате, и откуда вообще взялся этот формат.
Российские номера сотовых телефонов в международном формате состоят из трех элементов:
- +7 — международный код страны, Российской Федерации;
- ХХХ — три цифры, обозначающих префикс. Эти три цифры определяют название сотового оператора и регион регистрации номера;
- ХХХ-ХХ-ХХ — семь уникальных цифр, номер абонента, по которому также можно определить регион.
Отметим, что если речь идет про городской телефон, то может отличаться количество цифр в абонентском номере. Если в крупных городах географический код всегда состоит из трех цифр, то в других населенных пунктах он может включать четыре или пять цифр. Однако общее число цифр не изменится — код и номер абонента всегда состоит из десяти цифр. Поэтому, если региональный код четырехзначный, то абонентский номер включает шесть цифр, а если пятизначный код города, то пять.
Итак, чтобы записать номер в международном формате, следует набрать 11 цифр, не считая знака плюсика. Эта комбинация используется для звонков из зарубежных стран в Россию, внутри страны можно звонить, набирая вместо +7 восьмерку. В книге контактов лучше сразу сохранять номера в международном формате, потому что зачастую звонки через восьмерку не проходят, а также сможете гарантированно дозвониться на нужный номер, находясь в любой стране.
Номер «Мегафон» в международном формате имеет префиксы 920-929, 936 и 937. Номера МТС в международном формате отличаются префиксом 910-919, 980-989. Номера «билайн» в международном формате легко узнать по префиксам 903-909, 961-968, 976.
Однако стоит учитывать, что номера в одном коде могут быть разделены регулятором между несколькими операторами. Это связано с тем, что номерной ресурс ограничен, и выделить всем операторам, а их зарегистрировано более ста, коды с необходимым количеством номеров, невозможно.
Строго говоря, любые российские сотовые номера сразу пишутся в международном формате, так как без кода страны и кода оператора позвонить по ним невозможно.
Важно знать, что телефонный код +7 Россия разделяет с Казахстаном и Абхазией, а также мобильными номерами Южной Осетии. Другие республики после распада Союза перешли на собственные коды. Крым также использует российские коды +7-869 (местная связь в Севастополе), а сотовые номера Крыма в международном формате начинаются с комбинации +7978.
В международном формате можно набрать и любой городской (местный) номер. Если вам нужно позвонить, к примеру, в отель за рубежом, со стационарного телефона следует набрать 8-10-{код страны}-{код города}- номер абонента. А вот с сотового номера нужно набирать вместо 8-10 — плюс и код страны.
Цифра +7 определяет принадлежность номера к российской телефонной сети. Для других стран зарезервированы иные коды. Американский сотовый номер выглядит так:
+1 {код страны} ХХХ {код штата или города} ХХХХ-ХХ-ХХ {номер абонента}
Каждый штат США имеет свой префикс, а вот привязки номера телефона к оператору в США не существует. В одном штате может быть несколько вариаций префиксов.
Например, в Нью-Йорке используются коды 347, 212 и 646. В то же время, абонент с этим номером может переехать в какой угодно штат, роуминга внутри страны нет, так что по этим цифрам можно определить только, в каком штате номер был впервые зарегистрирован.
Также цифры, идущие после +1 в международном американском номере, позволяют определить, со стационарного или сотового номера вам звонят. К примеру, 212 код стационарной сети Нью-Йорка (но не в 100% случаев).
Как видим, американский номер в международном формате также включает 11 цифр. А вот украинский длиннее: здесь код соединения со страной состоит из трех цифр, +380. Украинские мобильные номера в международном формате выглядят так:
+380 {код страны} ХХ {код оператора} ХХХ-ХХ-ХХ {номер абонента}
У каждого сотового оператора Украины, соответственно, свои коды:
- 63, 73 и 93 — коды оператора Lifecell;
- 50, 66, 95, 99 — Vodafone;
- 67, 68, 69, 96, 97, 98 — префиксы для звонков в сети Киевстар;
- 91 — ТриМоб;
- 92 — PEOPLEnet;
- 94 — Интертелеком.
Отличается в стране формат национального набора. Как и в других странах Европы, вместо привычной нам восьмерки, используется ноль. Им можно заменить +380 при наборе номера, если звонок совершается внутри страны.
Белорусские сотовые телефоны в международном формате легко определить по начальным цифрам +375.
Хотя у Казахстана код страны совпадает с Россией, их номера определяются по префиксу: они имеют формат +7(6xx)xxx-xx-xx или +7(7xx)xxx-xx-xx. Префиксы российских сотовых операторов принадлежат исключительно диапазону (9хх).
Отметим, что на территории страны также действует нумерация с кодом начинающимся на восьмерку. Также, как в России, это специальные многоканальные номера. К примеру, 800 для бесплатных звонков с любого казахстанского номера.
Последовательность набора номера определяется телефонным планом нумерации — унифицированной системой, позволяющей пользователям сети отправлять и принимать звонки, а также определять звонящего (услуга определения номера включена во все тарифные планы сотовых операторов).
В мире существует два плана нумерации: открытый и закрытый. При первом местные вызовы можно совершать без национального номера (кода города), а при втором, то есть закрытом, необходимо набирать полный международный формат номера для звонка любого вида: местного, междугороднего, международного, либо национальный — в России это восьмерка вместо кода страны.
В основном страны применяют закрытый план нумерации, Москва сегодня полностью переведена на него. Отметим, что популярный термин “прямой номер” появился до того, как введен закрытый план. “Кривым”, на самом деле, является не номер с городским кодом, а тот, что можно набирать напрямую без кода города/оператора.
По планам Министерства цифрового развития, к 2020 году Россия должна была полностью перейти на закрытый план нумерации, но пока данный процесс не завершен. Это означает, что со временем во все городах нельзя будет набирать короткие 5-7-значные номера для местных вызовов, а всегда будет необходимо использовать полный международный формат номера.
Также планируется переход на международную систему национального формата номеров. По планам Минцифры, замена восьмерки на ноль будет произведена до 2025 года.
Сейчас у нас есть различие в наборе комбинаций при звонках внутри телефонной зоны, за ее пределы и при междугородних вызовах.
- ХХХ-ХХ-ХХ — звонки по местным городским номерам, никакие коды не нужны;
- 8 (Код города) ХХХ-ХХ-ХХ — междугородные звонки, набираются с кодом города;
- +7 (код города) (номер абонента) — для звонков из-за пределов РФ.
Если говорить о вызовах со стационарных телефонов, то для выхода на межгород нужно набирать 8-ку (в других странах 0).
При закрытом плане нумерации всегда нужно будет набирать расширенный вариант, то есть с +7 и кодом города, либо пользуясь национальным форматом.
Страны редко меняют план нумерации, но в ближайшем будущем это предстоит россиянам. Большинство абонентов не почувствуют разницы, ведь в телефонной книге смартфона удобно сразу сохранять длинную версию номера, лишь только редким пользователям стационарных телефонов придется всегда набирать длинные номера в международном формате.
Именно поэтому рекомендуем сохранять контакты в записной книжке своего телефона в международном формате. Такое простое правило позволит позвонить на любой номер, как находясь в России, так и за ее пределами. Тарификация звонков не отличается — стоимость минуты одинаковая как при наборе номера с +7, так и начиная с восьмерки.
Российский номер сотового телефона в международном формате состоит из 11 цифр, где +7 — это международный идентификатор страны, (9хх) — префикс оператора, также показывающий регион регистрации номера, а дальше идет семизначный номер абонента.
Для правильного набора местных номеров в международном формате нужно предварительно выяснить код города.
National conventions for writing telephone numbers vary by country. While international standards exist in the form of recommendation E.123 by the sector ITU-T of the International Telecommunication Union (ITU), national telephone numbering plans define the format of telephone numbers assigned to telephones and similar communication endpoints.
The presentation of telephone numbers in this article does not include any international dialing codes necessary to route calls via international circuits. In examples, a numeric digit is used only if the digit is the same in every number, and letters to illustrate groups. X is used as a wildcard character to represent any digit in lists of numbers.
Africa
Djibouti
All telephone numbers in Djibouti are eight digits long.
Fixed line numbers start with 21 or 27, then a fixed line locality code, followed by four digits.
Mobile numbers start with 77, then a mobile line locality code, followed by four digits.
The international dialing code for Djibouti is +253, so the format becomes «+253 XX YY ZZ ZZ».
Morocco
All telephone numbers in Morocco are 10 digits long (initial 0 plus nine numbers).
Landline numbers start with 05, followed by two digits for the regional area RR, then two digits for the local area LL, then 4 digits for the subscriber number XX XX: («05 RR LL XX XX» or «05RR LL XX XX»).
Mobile numbers start with 06 or 07, followed by the subscriber number («06 XX XX XX XX» or «07 XX XX XX XX»).
The international dialing code for Morocco is +212, so the format becomes «+212 Y XX XX XX XX» or «+212 YXX XX XX XX», also «+212 YXX-XXXXXX» as well, where Y is 5 for landlines or 6/7 for mobile.
Free calling numbers (green numbers) or call center numbers start with 080 or 090.
Kenya
Telephone numbers in Kenya uses a 9 digit format. The 9 digits used for local calls start with a «0» (trunk prefix) for domestic calls, followed by the 3 digit area/provider code and the final 6 digits (07XX XXX XXX). The international code for Kenya is «+254».
South Africa
South Africa uses 10 digit dialling which has been required since 16 January 2007. The 10 digits used for local calls (AAA XXX XXXX or 0AA XXX XXXX) consist of a 3 digit area/type code (the first digit in the area/type code is a trunk prefix) followed by 7 digits. All area codes, including mobile numbers, start with a «0» (trunk prefix) for domestic calls. When dialing from another country, the international calling code for South Africa is «+27» with the rest of the digits excluding the «0» trunk prefix (+27 AA XXX XXXX).
Asia
China
Telephone numbers in China are 10 or 11 digits long (excluding an initial zero which is required at times) and fall in at least four distinct categories:
- Landlines: In China, the length of phone numbers varies from city to city. It is usually written as (0XXX) YYY YYYY (For landlines registered in large metropolises, it is written in the format (0XXX) YYYY YYYY), where 0 is the trunk code, XXX is the area code (2 or 3 digits) and YYYY YYYY is the local number (7 or 8 digits). For example, (0755) XXXX YYYY indicates a Shenzhen number. XXXXYYYY is dialed locally, 0755 XXXX YYYY is dialed in other areas inside the country, while, for international calls to Shenzhen, the 0 is dropped and is written +86 755 XXXX YYYY.
- Mobiles: The 11-digit code is always written in full in the whole China e.g. 1WX YYYY ZZZZ. Each WX is assigned to a service provider while W is usually ‘3’ through ‘9’. The remaining 8 digits are the subscriber number.
- Toll Free: These are usually ten digit numbers beginning with 800 or 400. 800 (toll-free) are accessible only when called from landline phones, while 400 (shared toll) are accessible from all phones. 400 XXX XXXX or 800 XXXX XXXX.
- Service numbers: These are usually 3- to 5-digit numbers (e.g. Police is 110) used to access an emergency service (Fire 119, Ambulance 120, Police 110, Roadside assistance 12122) or a value-added service.
Hong Kong and Macau
Every number, except special service numbers, is an 8-digit number; they are grouped as XXXX YYYY. There are no area codes.
India
Telephone numbers in India are 10 digits long (excluding an initial zero which is required at times) and fall in at least four distinct categories:
- Landlines: Written as AAA-BBBBBBB, where AAA is the Subscriber Trunk Dialing code (long distance code) and BBBBBBB is the phone number. The total length of the Subscriber Trunk Dialing code and the phone number is 10 digits. The Subscriber Trunk Dialing code can be from 2 digits (11 or 011) up to 4 digits long.
- Mobiles: Written as AAAAA-BBBBB for ease of remembering (though the prefix is either 2-digits or 4-digits in the numbering plan). Mobile numbers which are not local need to be prefixed by a 0 while dialing, or by +91 (91 is the country code for India). A mobile number written as +91-AAAAA BBBBB is valid throughout India, and in other countries where the + is recognized as a prefix to the country code. Since 2015, calls from mobile phones to any other mobiles do not need to prefix with a 0. However, calls from landlines to non-local mobile numbers need to be prefixed with 0.
- Toll Free: These are usually ten digit numbers beginning with 1-800. Sometimes they are accessible (or are toll-free) only when called from the government-owned telephone corporation, BSNL/MTNL.
- Service numbers: These are usually three or four digit numbers (e.g. Police is 100) used to access an emergency service (Fire, Ambulance, Police, Roadside assistance) or a value-added service.
Iran
All telephone numbers in Iran are 11 digits long (initial 0 plus ten numbers). The first two or three digits after the zero are the area code. The possibilities are: (0xx) xxxx xxxx (for landlines), 09xx xxx xxxx (for cellphones) and 099xx xxx xxx (for MVNO).
When making a call within the same landline area code, initial 0 plus the area code must be omitted.
An example for calling telephones in the city of Tehran is as follows:
- xxxx xxxx (within Tehran, via a landline)
- 021 xxxx xxxx (Outside Tehran, or via a cellphone)
- +98 21 xxxx xxxx (outside Iran)
An example for mobile numbers is as follows:
- 09xx xxx xxxx (in Iran)
- +98 9xx xxx xxxx (outside Iran)
Japan
The traditional convention for phone numbers is (0AA) NXX-XXXX, where 0AA is the area code and NXX-XXXX is the subscriber number. This number format is very similar to the North American numbering plan, but the country has a trunk code of 0 instead of 1, so international callers (using +81) do not have to dial the trunk code 0 when calling to Japan. Telephone numbers were 9 digits long in Tokyo and Osaka until the late 1990s, when a seventh digit was added to the subscriber number. Densely populated areas have shorter area codes, while rural areas have longer area codes, but the last two digits of a five digit long area code (including the first zero) may also be the first two digits of the subscriber number. Area codes increase from north to south, except in areas such as the western Hokuriku region and the prefecture of Okinawa, where area codes increase from west to east or south to north.
Some telephone numbers deviate from this rule:
- Toll-free dialing and Navi Dial operations (0120-XX-XXXX, 0570-XX-XXXX, or 0800-XX-XXXX), where XX-XXXX is the subscriber number
- The area code 050 uses an 11 digit phone number (050-XXXX-XXXX), where XXXX-XXXX is the subscriber number
- 110 and 119 are examples of three digit emergency numbers
Malaysia
All area codes including mobile start with a «0» (trunk prefix) for domestic calls. If you are dialing from another country the international calling code for Malaysia is «60» which may be confusing; do not dial an extra «0» before the rest of the digits. For fixed line and mobile phone numbers, a dash is written in between the area/mobile code and the subscriber number, with an optional space before the last four digits of the subscriber number. For example, a fixed line number in Kuala Lumpur is written as 03-XXXX YYYY or 03-XXXXYYYY, while a fixed line number in Kota Kinabalu is written as 088-XX YYYY or 088-XXYYYY. A typical mobile phone number is written as 01M-XXX YYYY or 01M-XXXYYYY. Toll-free and local charge numbers are written as 1-800-XX-YYYY and 1-300-XX-YYYY respectively, while premium rate numbers are written as 600-XX-YYYY.
Pakistan
Telephone numbers in Pakistan have two parts. Area codes in Pakistan are from two to five digits long; the smaller the city, the longer the prefix. All the large cities have two-digit codes.
Smaller towns have a six digit number. Large cities have seven-digit numbers. Azad Jammu and Kashmir has five digit numbers. On 1 July 2009, telephone numbers in Karachi and Lahore were changed from seven digits to eight digits. This was accomplished by adding the digit «9» to the beginning of any phone number that started with a «9» (government and semi-government connections), and adding the digit «3» to any phone numbers that did not start with the number «9».[1]
It is common to write phone numbers as (0xx) yyyyyyy, where xx is the area code. The 0 prefix is for trunk (long-distance) dialing from within the country. International callers should dial +92 xx yyyyyyyy.
All mobile phone codes are four digits long and start with 03xx. All mobile numbers are seven digits long, and denote the mobile provider on a nationwide basis and not geographic location. Thus all Telenor numbers (for example) nationwide carry mobile code 0345 etc.
Universal access number
- 111 xxx xxx
Emergency Service Numbers
- 1xx
- 1xxx
Premium Rate services:
- 0900 xxxxx
Toll free numbers (For callers within Pakistan):
- 0800 xxxxx
Philippines
Telephone numbers in the Philippines are written as +63 (XXX) YYY ZZZZ for international callers. For domestic calls, the country code (+63) is omitted and a trunk prefix (0) is placed[citation needed]. For local calls, both the 0 and area code are omitted. Mobile numbers are written as +63 (XXX) YYY ZZZZ or 0 (XXX) YYY ZZZZ.
Singapore
In Singapore, every phone number is written as +65-XXXX-YYYY or +65 XXXX YYYY.
Mobile phones starts with 8/9, landline phone numbers starts with 6 while VOIP numbers starts with 3.
Subscriber numbers have 8 digits and there are no area codes.
Sri Lanka
Except for short codes and emergency numbers, all telephone numbers in Sri Lanka are ten digits long (initial 0 + nine numbers).
Landline phone numbers begin with the area code, then one digit for the operator code, then six digits for the primary telephone number.
Format: (XXX Y ZZZZZZ) where:
- «xxx» denotes the area code. All area codes begin with the number 0.
- The operator code for fixed (landline) numbers is «y».
- «zzzzzz» denotes the primary telephone number, which has six digits.
Mobile numbers start with the mobile operator code (which begins from 07X, followed by seven digits for the main telephone number).
Format: (XXX ZZZZZZZ) where:
- When dialing a mobile number, «xxx» represents the mobile operator code. All mobile operator codes begin with the number 07.
- «zzzzzzz» represents the main telephone number of seven digits.
The international dialing code for Sri Lanka is +94, so the format becomes «+94 XX Y ZZZZZZ» for landlines and the format becomes «+94 XX ZZZZZZZ» for mobile numbers.[2]
South Korea
South Korean phone numbers can be as short as 7 digits and as long as 11 digits, because, when making a local call (i.e. in the same city), there is no need to dial the area code. South Korean area codes are assigned based on city.
Landline phone numbers
Landline home numbers are usually written as: 0XX-XXX-XXXX or (0XX) XXX-XXXX where 0XX indicates an area code. (0XX) XXX-XXX and 0XX XXX XXXX (without hyphens) are comprehensible as well. The area code may be two digits long for some cities such as Seoul and Gwacheon (these two cities use the same area code) and three digits for other cities such as Incheon, Busan and most of the cities in Gyeonggi-do. The middle three-digit part is extended to four digits in many areas due to the increased number of telephone users.
In the international context, 82 0XX-XXX-XXXX is commonly used as well. For international calls, «0» in the area code is often omitted, because it is not necessary to dial 0 from foreign countries. Therefore, it is better written as: 82-(0)XX-XXX-XXXX or 82-(0)XX-XXXX-XXXX The plus (+) sign is often added to the country code too (e.g., +82 0XX-XXX-XXXX or +82-0XX-XXXX-XXXX).
Mobile phone numbers
For mobile numbers, 016490641 so on. As with the landline home numbers, the mobile numbers’ middle three-digit part is extended to four digits (e.g., 016490641) due to the increased number of mobile phone users.
Business numbers
If a number starts with 070, the number does not belong to any particular area, and is a number given by an Internet telephone service. In this case, 070 is not usually put in the brackets, neither ( ) nor ).
In the business context, the numbers in the format of 15XX-XXXX and 16XX-XXXX are business representative agency or customer services. While the numbers starting with 080 (e.g., 080-XXX-XXXX) are also business-related numbers but are usually toll-free customer service centers. Also in this case, 15XX, 16XX or 070 are not put in the brackets, neither ( ) nor ).
National service numbers
There are national telephone services which have phone numbers in the format of 1XX or 1XXX, without any area code. For example, 114 is for telephone yellow page, 119 is for fire/emergency number, 112 is for police station center, 131 is for weather forecast information, 1333 is for traffic information, and so on. The number 111 is for reporting spies, especially from North Korea. It used to be 113, so most of senior citizen still believe it is the number for reporting spies. These numbers do not need any brackets.
Alternative numbers
If there are multiple numbers used for one person/entity, the symbol «~» is usually used to avoid repetitions. For example, if one company has three phone numbers—031-111-1111, 031-111-1112 and 031-111-1113—then they are shortened as in 031-111-1111~3.
If the numbers are not consecutive, then the last digit is written together with commas. For example, if a company has three numbers—031-111-1111, 031-111-1115, 031-111-1119, then they are shortened as in 031-111-1111, 5, 9.
Taiwan
Landline numbers in Taiwan are written with the area code in parenthesis [with phone numbers total 9 digits]
Example: (02) XXXX YYYY for phone numbers in Taipei area.
Mobile phones have 3 digit «company code» assigned to different mobile service carriers such as (09**) XXXXXX followed by a 6 digit phone number.
(note: Mobile carriers could have multiple company codes)
Thailand
All numbers in Thailand, whether for landlines or mobile reception, consist of eight digits, xxxx xxxx in the government’s official format. When calling domestically, landline numbers are preceded by a zero (0 xxxx xxxx, example 0 5381 0595) while mobile numbers are preceded by 0 plus one digit (0x xxxx xxxx, example 06 9756 4509). Thais often confuse the current numbering system with the old provincial area code system, which no longer exists as area codes were integrated into all phone numbers in 2005. Because of this, unofficially people often write numbers as 0xx xxx xxx (053 810 595). Calling a Thai phone number from outside Thailand, one drops the 0 and adds the +66 country code. Example +66 5381 0595.[3]
Oceania
Australia
Most Australian telephone numbers are 10 digits long, and are generally written 0A BBBB BBBB or 04XX XXX XXX for mobile telephone numbers, where 0A is the optional «area code» (2,3,7,8) and BBBB BBBB is the subscriber number. (http://www.acma.gov.au/Industry/Telco/Numbering/Numbering-Plan/phone-number-meanings-numbering-i-acma)
When the number is to be seen by an international audience, it is written +61 A BBBB BBBB or +61 4XX XXX XXX. When written for a local audience, the optional area code is omitted. The area code is often written within parentheses (0A) BBBB BBBB. Mobile numbers should never have parentheses.
Ten-digit non-geographic numbers beginning with 1 are written 1X0Y BBB BBB, where X = 8 for toll free numbers, X = 3 for fixed-fee numbers and X = 9 for premium services. Six-digit non-geographic numbers are written 13 BB BB or 13B BBB; these are fixed-fee numbers. Seven-digit 180 BBBB numbers also exist. ‘B’s are sometimes written as letters.
New Zealand
Almost all New Zealand telephone numbers are seven digits long, with a single-digit access code and a single-digit area code for long-distance domestic calls. Traditionally, the number was given as (0A) BBB-BBBB, with the two first digits (the STD code) often omitted for local calls. The brackets and the dash are also often omitted. Mobile numbers follow the same format, but with the area code being two digits, i.e. (02M) BBB-BBBB. ( Some mobile numbers are longer: (021)02BBBBBB, (021)08BBBBBB, (020)40BBBBBB, (020) 41BBBBBB and (028) 25BBBBBB; and some are shorter: (021)3BBBBB, (021)4BBBBB, (021)5BBBBB, (021)6BBBBB, (021)7BBBBB, (021)8BBBBB and (021)9BBBBB)
There are also free-phone numbers (starting with 0800 or 0508) that are given in the format 0800-AAA-AAA. It is not uncommon for the 0800 and 0508 to be enclosed in brackets, although this is not strictly correct as the brackets denote optional parts of the number, and the 0800 and 0508 is required.[4]
Recently with 8 digit mobile numbers becoming more common the prefix-4 digits-4 digits format has been adopted for readability: 022 1234 5678.
For international use, the prefix +64 is substituted for the leading zero, giving +64-A-BBB-BBBB for land-lines, and +64-MM-BBB-BBBB for mobile numbers.
Europe
Belgium
Belgian telephone numbers consist of two major parts: Firstly ‘0’, secondly the «zone prefix» (A) which is 1 or 2 digits long for landlines and 3 digits long for mobile phones and thirdly the «subscriber’s number» (B).
Land lines are always 9 digits long. They are prefixed by a zero, followed by the zone prefix. Depending on the length of the zone prefix, the subscriber’s number consists of either 6 or 7 digits. Hence land line numbers are written either 0AA BB BB BB or 0A BBB BB BB.
Mobile phone numbers always consist of 10 digits. The first digit of the «zone prefix» of a mobile number is always ‘4’. Then follows 2 digits indicating to which Mobile Operator’s pool the number originally belonged when it was taken into usage. The fourth digit represents a «sub-group» of this pool and has no additional meaning other than increasing the amount of possible numbers. The subscriber’s number consists of 6 digits. Hence, mobile phone numbers are written 04AA BB BB BB. Sometimes, the last 6 digits are written in two groups of 3 digits to increase readability: 04AA BBB BBB.
Numbers are sometimes written with a slash in between the zone prefix and the subscriber’s number. This is the case for both land lines and mobile phone numbers. Sometimes, dots are written between the blocks of the subscriber’s number. Examples: 0AA/BB BB BB, 0AA/BB.BB.BB; for mobile numbers: 04AA/BB BB BB, 04AA/BB.BB.BB or 04AA/BBB.BBB.
The international code prefix for Belgium is «+32». When dialing a number with the prefix, the 0 can be dropped, e.g.: +32 9055.
Denmark
Danish telephone numbers are eight digits long and are normally written
- in four groups of two digits each, with the groups separated by spaces: AA AA AA AA,
- in two groups of four digits each, with the groups separated by a space: AAAA AAAA,
- in one group of two digits followed by two groups of three digits each, with the groups separated by spaces: AA AAA AAA, or
- all in one go: AAAAAAAA.
The third option, AA AAA AAA is not commonly used for personal (landline or mobile) numbers, but is mostly found in corporate numbers, especially in advertizing. The standard formats – which when spoken divide numbers into ranges from 00 (zero zero) to 99 (ninety-nine) – limit the possible range of the ability to create telephone numbers that are easy to remember; dividing the numbers into groups of three expands the mnemonic possibilities.
Danish emergency and service numbers are three digits long and are written AAA. Danish short numbers used for text messaging services are four digits long and are written AAAA.
Finland
France
French telephone numbers are 10 digits long, usually written in groups of two separated by spaces, in the format 0A BB BB BB BB where 0 (the trunk prefix) was created in 1996 to be a carrier selection code, and A is the «territorial area code» included in the subscriber number A BB BB BB BB.
Sometimes, it is also written in the format 0A.BB.BB.BB.BB using periods instead of spaces, but this is less common.
The A (territorial area code) can be 1 to 5 (for geographic-based numbers, according to location: Paris/Suburbs, northwest France, northeast France, southeast France, and southwest France, respectively), and it designates nationwide numbers when it is 6 or 7 (mobile numbers), 8 (special numbers), or 9 (phone over IP over xDSL/non-geographic numbers).
The numbering plan is a closed one; all digits must always be dialed.
The first two or three B can designate the area (old area code) for geographic numbers, or the operator to whom the number resource belongs.
There are also «short numbers» for emergencies (such as 112), that are written 1C or 1CC; and short numbers for special services, written 10 CC, 11C CCC, or 36 CC. 00 is the international access code.
International format is +33 A BB BB BB BB where the leading trunk prefix 0 disappears (it must not be dialed from abroad). This format can be directly used in mobile phones.
Germany
German telephone numbers have no fixed length for area code and subscriber number (an open numbering plan).
There are many ways to format a telephone number in Germany. The most prominent is DIN 5008 but the international format E.123 and Microsoft’s canonical address format are also very common.
Trunk access code is 0 and international call prefix code is 00.
Form | Example |
---|---|
DIN 5008 | 0AAAA BBBBBB |
DIN 5008 with Extension | 0AAAA BBBBBB-XX |
DIN 5008 international | +49 AAAA BBBBBB |
E.123 local | (0AAAA) BBBBBB |
E.123 international | +49 AAAA BBBBBB |
Microsoft | +49 (AAAA) BBBBBB |
Old | 0AAAA-BBBBBB |
Very old | 0AAAA/BBBBBB-XX |
Numbers are often written in blocks of two. Example: +49 (A AA) B BB BB (Note the blocks go from right to left)
The very old format and E.123 local form are often used by older people but also for technical reasons.
Greece
Greek telephone numbers are ten digits long, and usually written AAB BBBBBBB or AAAB BBBBBB where AAB or AAAB is the 2- or 3-digit national area code plus the first digit of the subscriber number, and BBBBBBB or BBBBBB are the remaining digits of the subscriber number. The entire number must always be dialed, even if calling within the same local area; therefore, the national destination code is not separated from the subscriber number. According to international convention, numbers are sometimes written +30 AAB BBBBBBB or +30 AAAB BBBBBB to include the country calling code.
Hungary
In Hungary the standard lengths for area codes is two, except for Budapest (the capital), which has the area code 1. Subscribers’ numbers are six digits long in general. Numbers in Budapest and cell phone numbers are seven digits long.
Iceland
Phone numbers in Iceland are seven digits long and generally written in the form XXX XXXX or XXX-XXXX.
Ireland
Phone numbers in Ireland are part of an open numbering plan with varying number lengths. The area code system similar to some other northern European countries. Unlike the UK, Irish fixed line numbering is divided into a number of regions which are (except Dublin) further subdivided in a hierarchical structure, with the largest town often (but not always) taking 0A1.
Area codes start with a trunk prefix «0» and extend for up to four digits but usually 3; followed by the local phone number of up to seven digits.
In industry jargon, these area codes and prefixes are referred to as NDCs (National Dialing Codes). This is the term used by ComReg and technical documents, as they include non-geographic codes. Historically, like the UK, the term STD code (Subscriber Trunk Dialling) was used.
However, the terminology is archaic and is no longer universally understood and should not be used to avoid confusion.
Dublin uses the shorter (01) code which is not further subdivided. Other cities and major towns usually have codes ending in 1. Cork for example is 021, Galway 091, Limerick 061 etc.
The leading zero is always omitted when dialling from outside the country.
Local phone numbers are either 5, 6 or 7-digits long. In 7-digit numbering they are usually grouped as BBB BBBB, 6-digit numbers are grouped BBB BBB and 5-digit numbers are normally all grouped together BBBBB
Grouping of numbers is not strictly adhered to, but usually fairly consistent. The area code should always be kept separated with a space or surrounded by brackets and not merged into the local number.
The use of hyphens is discouraged, particularly on websites as it can prevent mobile browsers identifying the number as a clickable link for easier dialling.
Fixed line numbers are normally presented as follows:
- 01 BBB BBBB for a Dublin number (7 digit)
- 021 BBB BBBB for a Cork number (7 digit)
- 064 BBB BBBB for a Killarney number (7 digit)
- 061 BBB BBB for a Limerick number (6 digit)
- 098 BBBBB for a Westport number (5 digit)
- 0404 BBBBB for a Wicklow number (5 digit)
Area codes may also be surrounded by brackets, but this practice is falling out of use, as local dialing without the area code is optional on landlines and the area code must always be dialled on mobile phones.
The Irish telecommunication regulator, ComReg has been gradually rationalising area codes by merging and extending local numbering to 7-digits in the format 0AA BBB BBBB. This is being carried out only where necessary to avoid disruption. This means that varying fixed line number lengths will continue to exist in Ireland for the foreseeable future.
Mobile numbers are presented as follows:
08A BBB BBBB
Brackets should not be used around the mobile prefix as it is never optional and must always be dialled, even from another phone with the same prefix.
Special rate numbers, such as free phone/toll free and premium rate are usually grouped:
Freephone: 1800 BB BB BB or (spoken as one-eight-hundred)
Local rate: 1850 BB BB BB (eighteen-fifty)
1550 BB BB BB (read as fifteen-fifty)
However, for memorability, this is not consistently adhered to.
Alphanumeric characters can also be used in presenting numbers for added memorability, but it is much less common than in North America
For example:
18AA 99 TAXI
Note: These special rate numbers are not reachable from outside Ireland and should never be presented as +353 1800 or +353 1550 etc. as this would result in a connection to an unrelated Dublin landline in the +353 1 BBB BBBB range.

Italy
Phone numbers in Italy have variable length. There’s no well established convention about how to group digits or which symbol to use, but this is hardly an issue since all the digits are always dialed.
Netherlands
Since 10 October 1995 (Operation Decibel) all telephone numbers in the Netherlands are 10 digits long (including the trunk prefix ‘0’). The area code (‘A’) is commonly separated with a dash (‘-‘) and sometimes a space from the subscriber’s number (‘B’). Alternatively, the area code (including the trunk prefix) can be enclosed in parentheses.
The length of the area code for landlines is either 2 or 3 digits, depending on the population density of the area. This leaves 7 or 6 digits for the subscriber’s number, resulting in a format of either 0AA-BBBBBBB or 0AAA-BBBBBB. Cellphone numbers are assigned the 1-digit area code 6, leaving 8 digits for the subscriber’s number: 06-CBBBBBBB, where subscriber’s number (‘C’) is neither 6 nor 7. Service numbers (area codes 800, 900, 906 and 909) have either 4 or 7 remaining digits, making them 8 or 11 digits in total: 0AAA-BBBB or 0AAA-BBBBBBB. The area code 14 has no trunk prefix and is used for government numbers, currently only for municipalities. The remaining digits represent the area code of the municipality. Therefore, the length 14 numbers total either 5 or 6 digits: 14 0AA or 14 0AAA
The trunk prefix ‘0’ is dropped when prefixed by the country code: +31 AA BBBBBBBB, +31 6 CBBBBBBB, etcetera. Note that there is not a trunk prefix for the 14 series so the international number becomes +31 14 0AAA.
Norway
Norwegian telephone numbers are 8 digits long. A number to a fixed line is written in four groups of two separated by spaces, AA AA AA AA. Phone numbers in 8xx series is written in three groups, AAA AA AAA. This makes it easy to determine if the B-number is SMS capable. Mobile numbers start with 4 or 9.
Poland
Telephone numbers in Poland are 9 digits long. For mobile phones, the preferred format is AAA-AAA-AAA. For landline phones, the preferred format is AA-BBB-BB-BB, where AA is area code. Occasionally, you can encounter numbers formatted as (AA) BBB-BB-BB. Omitting area code is not permitted, because nowadays it is always required.
Portugal
Telephone numbers in Portugal Country code +351 are 9 digits long. According to present day a number to a fixed line is written in three groups of two separated by spaces, AAA AAA AAA. Cellphone numbers are written in three groups, AAA AAA AAA. Mobile numbers start with 9.
Romania
Starting with 2002 phone numbers in Romania are 10 digits long, the first digit always being 0. The preferred format is AAAA-AAA-AAA for mobile, except for landline phones in Bucharest where the preferred format is AAA-AAA-AA-AA.
Russia
Russia has an open numbering plan with 10-digit phone numbers. Trunk prefix is 8 (or 8~CC when using alternative operators, where CC is 21–23, 52–55). International call prefix is 8~10 (or 8~CC when using alternative operators, where CC is 26–29, 56–59). The country code is +7.
Length of geographical area codes (A) is usually 3 to 5 digits; length of non-geographical area codes is 3. The groups of digits in the local subscriber’s number (B) are separated by dashes (‘-‘): BBB-BB-BB, BB-BB-BB, B-BB-BB. The area code is included in parentheses, similarly to E.123 local notation: (AAA) BBB-BB-BB, (AAAA) BB-BB-BB, (AAAAA) B-BB-BB.
Area code dialing is optional in most geographical area codes, except Moscow (area codes 495, 498, 499); it is mandatory for non-geographical area codes. E.123 international and Microsoft formats are used for writing local phone numbers as well; international prefix and country code +7 are replaced with trunk code 8 (or 8~CC) when dialing a mandatory area code.
Even though trunk code is not needed for calls within the same geographical area, recent convention adds the default trunk code to the phone number notation: 8 (AAAA) BB-BB-BB. For mandatory area code dealing plans, notation 8 AAAA BB-BB-BB is used. These formats are a mix of Microsoft format and E.123 local notation.
Mobile phones require full 10-digit number which starts with 3-digit non-geographical area codes 900–990. For international calls abroad or international roaming calls to Russia, E.123 international notation with an international call prefix ‘+’ is the only allowed calling number format. For local calls both 8 and +7 are accepted as a trunk code.
Form | Example |
---|---|
Old | BBB-BB-BB |
Old with area code | (AAA) BBB-BB-BB |
Conventional | 8 (AAA) BBB-BB-BB |
Microsoft | +7 (AAA) BBB-BB-BB |
Conventional (mandatory area code) | 8 AAA BBB-BB-BB |
E.123 international | +7 AAA BBB BB BB |
Spain
Spanish telephone numbers are nine digits long, starting with ‘9’ or ‘8’ for fixed lines (excluding ’90x’ and ’80x’) or with ‘6’ or ‘7’ for mobile phones.
The first group in fixed lines always identifies the dialed province. That group might be of 2 or 3 digits; for example, 91 and 81 are for Madrid while 925 and 825 are for Toledo. The second group is always of 3 digits as it formerly identified the telephone exchange (it now identifies the telephone area).
When the first group is 2 digits long (as in Madrid), the number is usually written in four groups of 2-3-2-2 digits (AB CCC DD DD)
When the first group is 3 digits long (as in Toledo), the number is usually written in 3 groups of 3 digits (ABB CCC DDD) but the form 3-2-2-2 (ABB CC CD DD) is not uncommon.
Mobile numbers are usually grouped by threes, ABB CCC CCC, but the form 3-2-2-2 is also seen.
Sweden
Swedish telephone numbers are between eight and ten digits long. They start with a two to four digit area code. A three digit code starting with 07 indicates that the number is for a mobile phone. All national numbers start with one leading 0, and international calls are specified by 00 or +. The numbers are written with the area code followed by a hyphen, and then two to three groups of digits separated by spaces.[6]
Type | Format |
---|---|
National 10 digit | 0A-XXX XXX XX or 0AA-XXX XX XX or 0AAA-XX XX XX |
National 9 digit | 0A-XXX XX XX or 0AA-XX XX XX or 0AAA-XXX XX |
National 8 digit | 0A-XX XX XX or 0AA-XXX XX |
Mobile 10 digit | 07A-XXX XX XX or 07AA-XX XX XX |
International | +CC AAA-XXX XX XX or 00CC AAA-XXX XX XX |
Switzerland
Swiss telephone numbers are ten digits long, and usually written 0AA BBB BB BB where 0AA is the national destination code and BBB BB BB is the subscriber number. The entire number must always be dialed, including the leading 0, even if calling within a local area, therefore the national destination code is not separated from the subscriber number. According to international convention, numbers are sometimes written +41 AA BBB BB BB to include the country calling code. Certain nationwide destination codes, such as for toll-free or premium-rate telephone numbers, are written 0800 BBB BBB or 0900 BBB BBB. Short numbers are used for emergency services such as 112 that are written 1CC or 1CCC.
Turkey
In Turkey the format for telephone numbers is commonly seen as 0BBB AAA AA AA. While landline numbers having the prefix 02BB AAA AA AA, 03BB AAA AA AA, or 04BB AAA AA AA[7] mobile numbers have the prefix 05BB AAA AA AA. Landline area codes are separated by cities and only one city, Istanbul, has two area codes: 216 for the Asian side, and 212 for the European side. Mobile numbers however are separated by carriers. There are three mobile carriers in Turkey: Vodafone TR, Turkcell and Turk Telekom. Turkcell has the prefix 053B AAA AA AA, Vodafone TR has the prefix 054B AAA AA AA, and Turk Telekom has the prefix 055B AAA AA AA.
Since 9 November 2008, with the passing of the Number Carriability Regulation by ICTA, mobile numbers can be carried from one mobile carrier to the other, without having to change the prefix.[8] This caused dialing 05BB to call another number on the same carrier to become mandatory. Calls to numbers which were carried to another operator are signaled by a unique sound upon dialing, to signify that the recipient is on another network and alert them against potentially unwanted interconnection charges. The same regulation passed on 10 September 2009 regarding landline numbers, without the requirement to dial the prefix among numbers with the same geographical area, sharing the same prefix.
The «0» on every prefix is an Area Code Exit code that must be dialed when a number with a different area code is being called. So when calling from outside of Turkey those 0s are not dialed. The dialing format when calling from outside Turkey is +90 BBB AAA AA AA and NOT +90 0BBB AAA AA AA. Unlike the North American system, the Country Exit Code isn’t 011 but 00. So it is one «0» to exit area and one more «0» to exit the country.
Ukraine
There are many recommendations for recording phone numbers. The most common in the world is Recommendation E.123 E.123 International Telecommunication Union[9]
and the standard format for Microsoft telephone numbers Microsoft.[10]
There is an international format for recording a telephone number containing the country code, settlement code and telephone number, and the national format containing the settlement code and telephone number.
To record Ukrainian telephone numbers, it should be remembered that the country code for Ukraine is: +380, telephone codes for settlements do not have an initial zero, long-distance prefix: 0.
Writing telephone numbers | |
Phone number | Note |
+380 44 123 45 67 | E.123, international format: country code, settlement code and telephone number are separated by spaces |
(044) 123 45 67 | E.123, national format: long-distance prefix and city code in parentheses (national format: long-distance prefix and settlement code in parentheses due to possible confusion needs constant additional clarification), п. 2.8 [9] ), the phone number is separated from the code and separated by spaces |
+380 (44) 1234567 | Microsoft, international format: country code, space code, settlement code in brackets, space code, telephone number. |
Often, they mistakenly write down phone numbers, transferring the last zero from the country code to the settlement code, for example:+38 044 1234567 or +38 (044) 1234567. Such entry is incorrect because the telephone code of Ukraine is +380, and the codes of settlements or codes of mobile networks cannot begin with “0” or “1”.
United Kingdom
Dialling codes, also known as «area codes» are optional for local callers (often surrounded by parentheses, or separated with a dash), though there are trials running to make them mandatory,[11] and are followed by the customer’s telephone number.
Codes with the form 02x are followed by 8-digit local numbers and are usually written as 02x AAAA AAAA or (02x) AAAA AAAA. Area codes with the form 011x or 01×1 are used for many of the major population centres in the UK, are always followed by 7-digit local numbers and are usually written as 01xx AAA BBBB, (01xx) AAA BBBB or 01×1-AAA BBBB (the latter formerly the recommended format for six major metropolitan areas in the UK). Other area codes have the form 01xxx with 5 or 6 figure local numbers written as 01xxx or (01xxx) followed by subscriber number AAAAA or AAAAAA; or have the form 01xx xx with 4 or 5 figure local numbers written as 01xx xx or (01xx xx) followed by subscriber number AAAA or AAAAA.
Numbers for mobile phones and pagers are formatted as 07AAA BBBBBB and most other non-geographic numbers are 10 figures in length (excluding trunk digit ‘0’) and formatted as 0AAA BBB BBBB. However, these numbers are sometimes written in other formats. 9 figure freephone numbers are 0500 AAAAAA and 0800 AAAAAA and there is one number of 8 figures length: 0800 1111 (Childline).
Domestically, there are also a number of special service numbers such as 100 for the operator, 123 for the speaking clock and 155 for the international operator, as well as 118 AAA for various directory enquiry services, and 116 AAA for various helplines. For some services, the number you call will depend on which operator you use to connect the call. 112 and 999 work for calling the emergency services. These numbers cannot be called from abroad.
When calling from abroad, the initial ‘0’ trunk prefix is not required; it is, however, commonplace to represent telephone numbers with both the international code and the ‘0’ trunk prefix — which is typically placed within parentheses — but this representation is inconsistent with the E.123 international standard.[12]
North America
United States, Canada, and other NANP countries
Twenty-four countries and territories share the North American Numbering Plan (NANP), with a single country code, 1. The formatting convention for telephone numbers is NPA-NXX-XXXX, where NPA is the three-digit area code, and NXX-XXXX is the seven-digit subscriber number.[13]
NPA has the same syntax of NXX since the implementation of interchangeable area codes in 1995. The prefix NXX of the subscriber number is a code for the central office, unique in the numbering plan area. The place holder N stands for the digits 2 to 9, as the subscriber number may not begin with the digits 0 and 1. It is a closed telephone numbering plan in which all subscriber telephone numbers have seven digits, in addition to the three-digit area code.
Under all-number calling, a numbering plan introduced around 1960, local calls within an area code were placed by dialing NXX-XXXX, omitting the area code, known as seven-digit dialing. Only calling a destination in a different area code required dialing the destination area code, known as ten-digit dialing. Due to the need for a larger telephone number pool in many regions, seven-digit dialing is becoming rare in the United States. With the rapid growth of telephony in the late 20th century, many metropolitan areas saw the introduction of additional area codes. Multiple area codes were assigned to the same numbering plan area, a configuration known as an overlay numbering plan. Calls within an overlay are still local calls, despite the need for ten-digit dialing.
In general, placing long-distance calls requires dialing the trunk code 1, but this may be optional in some areas.
Canada
Canada is a member of the North American Numbering Plan, but administers its numbering resources individually, under guidance from the NANP Administrator. The Canadian government has stated on its Language Portal of Canada that telephone numbers are to be written with a hyphen between each sequence, as follows: 1-NPA-NXX-XXXX or NPA-NXX-XXXX.[14] 10-digit dialing is now required throughout most of Canada, including all of British Columbia, Alberta, Saskatchewan, Manitoba, Quebec, Nova Scotia, and Prince Edward Island, as well as most of Ontario. Areas not yet requiring 10-digit dialing are Ontario’s 807 area code, Newfoundland, New Brunswick, the Yukon, Northwest Territories, and Nunavut, although 10-digit dialing may be accepted in some of these areas.
In the province of Québec, where French is the first language, the Office québécois de la langue française has established that telephone numbers must be written with spaces first and then a hyphen for the last sequence, as follows: 1 NPA NXX-XXXX.[15] Educational institutions of Quebec will mark improperly written telephone numbers as orthographical mistakes in academic texts.[citation needed]
Mexico
Mexican telephone numbers have ten digits. They can consist of a two-digit (NN) area code and an eight-digit local number (ABCD XXXX) or a three-digit area code (NNN) with a seven-digit local number (ABC XXXX).
As of August 3, 2019 all the indicators and access codes (01, 044, 045) are deprecated, therefore all telephone numbers, for landline or mobile service, are dialed with ten digits.[16]
The formatting convention of a telephone number is
- ABCD XXXX or NN ABCD XXXX or (NN) ABCD-XXXX
- ABC XX XX or NNN ABC XXXX or (NNN) ABC-XX-XX
The international country code prefix for Mexico is 52. When dialing a number it must be formatted as «plus sign + country code + 10-digit number» e.g.: +52 NNN ABC XXXX
Central America
Some Central American countries write the country code for their own and other Central American countries in parentheses, instead of using a + sign, as recommended by E.123. For example, for a number in Costa Rica they would write (506) 2222-2222 instead of +506 2222-2222. On the other hand, Guatemala does have the custom of using the + sign. It is quite common for Central American businesses to write the whole phone number, including the country code in parentheses, on business cards, signs, stationery, etc.
Costa Rica
Costa Rican telephone numbers are 8 digits long, and are usually written in the format 2NNN-NNNN (for landlines), 8NNN-NNNN (for mobile telephone numbers from local telephone company ICE), 6NNN-NNNN (for mobile telephone numbers from Movistar) and 7NNN-NNNN (for mobile phone numbers from Claro).[17] Toll-free numbers use the format 800-NNN-NNNN and premium-rate telephone numbers are written 90x-NNN-NNNN where x varies according to the type of service offered. There are also «short numbers» for emergencies such as 911.
When Costa Rica switched from 7 to 8 digit numbers, it used a scheme similar to the 8 digit number scheme already in place in El Salvador at that time.
El Salvador
El Salvadoran telephone numbers are 8 digits long, usually written in the format 2NNN-NNNN (for landline use) and 7NNN-NNNN (for mobile telephone numbers). Premium-rate numbers start with a 9.
Guatemala
Guatemalan telephone numbers are 8 digits long and written in the format 2NNN-NNNN for landlines in Guatemala City, 6NNN-NNNN for landlines for the rest of municipalities in the Guatemala Department, and 7NNN-NNNN for landlines in Rural Guatemala / rest of country. Non-geographic numbers (mobile) are 5NNN-NNNN, 4NNN-NNNN, and 3NNN-NNNN. Within each area, there are different service providers. The following 3 digits indicate the service provider. However, their assignment is on a first-come first-served basis.
Additionally there are special numbers with the following conventions: 3 digit numbers for emergency systems, four digit numbers, 15NN for information and governmental institutions and 17NN for commercial and banking institutions with a high call influx, 6 digit numbers for Telephone carriers numbers and making operator assisted calls, collect calls. These calls are billed at different rates. 1-800: Toll-free calls redirected to out of country offices and 1-801: Local toll-free calls.[18]
Honduras
Honduran telephone numbers have either 7 digits (for landlines), which are usually written NNN-NNNN, or 8 digits (for mobile numbers), which are written NNNN-NNNN. The fact that landline and mobile numbers are different lengths sometimes causes confusion.
In 2010, an additional digit (2) was added to the start of land line numbers, thus standardizing the length at 8 digits.
South America
Argentina
Argentine telephone numbers always consist of 11 digits, including the geographical area code.
Area code
The area code can have 3, 4 or 5 digits, the first being always 0 (indicative of long distance calls). Moreover, in 1999 the whole country (except Buenos Aires, and Greater Buenos Aires) was divided into two zones. Roughly and with exceptions, one includes most of the northern half of the country; and the other, most of the southern half, though the actual reason for this division is not geographical, but the fact that each zone is administered by a different company.
So, the second digit of area codes can be 1 (only in Buenos Aires and Greater Buenos Aires code «011») or else a 2 (for towns in the southern half of the country) or a 3 (for the northern half). For example, (011) for Buenos Aires, (0341) for Rosario, (02627) for San Rafael. And the subscriber’s number will accordingly have 6, 7 or 8 digits, to complete the eleven digits.
Phone numbers are mostly written as:
- (011) xxxx-xxxx (Note that only the (011) code has 3 digits),
- (0xxx) xxx-xxxx or
- (0xxxx) xx-xxxx
The area code is usually written between brackets.
Subscriber number
In 1999, a general reform was introduced to telephone numbers, including the 1, 2 and 3 for area codes as explained above, and adding a 4 at the beginning of all subscriber’s numbers. However, since the reform some local numbers starting with a 5 are beginning to appear. Moreover, a hyphen is usually placed to separate the last four digits. Code areas do not usually include one single city or town, but several neighbouring towns. So, the part before the hyphen (called a prefix) is usually indicative of either a town within the code area, or even of a part of a larger city, which is assigned several prefixes. As a matter of fact, each area code has only a limited number of prefixes assigned, and these are locally limited within the area.
For example, the (0342) area has numbers with a 456- prefix, mostly located in the centre of Santa Fe. It also has numbers with a 460- prefix, usually for phone lines in the north east of the city. And there are lines with a 474- prefix, located in Santo Tomé. But no 444- prefix exists within this area. As for the part after the hyphen, it may usually be any succession of four digits, though sometimes a prefix is shared by two or more small towns, and then, the first digit after the hyphen carries the distinction between towns.
Sometimes, a prefix is reserved for official numbers, that is for offices depending on the national, provincial or local state. In the (0342) area, this is 457-, and phones within this prefix communicate with each other, by simply dialing the four final digits, though from other phones the prefix must be dialled as well.
Mobile phones
Mobile phones use the same area codes as landline telephones, but the number begins with a «15», added to a string of 6, 7 or 8 digits, just as described above. After the «15», the remainder of the number can start with a 3, a 4, a 5 or a 6. This «15» may be dropped when a call is made to a mobile phone in a different code area. And when sending text messages, the receiver’s number is best dialled both without the «15» and with the long distance code, even if both sender and receiver share a code area, but without the initial «0».
To sum up, given the mobile phone (011) 154-123-4567, you will call it by dialing:
- 154-123-4567 (within the same code area),
- (011) [15]4-123-4567 (from a different code area, including or omitting the 15),
And you will send messages to:
- 11 4-123-4567 (even when your phone has also a 011 number).
Special numbers
Two sorts of special numbers exist in Argentina. On the one hand, three-digit numbers are used for special services such as to call the police, fire brigade or emergency doctors, as well as to hear the official time. Also telephone companies have three-digit numbers to report a problem in the lines, or to ask for another subscriber’s number, when a paper directory is not available.
Additionally, there are other longer numbers. These include (but are not limited to):
- 0800 xxx abcd
- 0810 xxx abcd
- 0600 xxx abcd
(where the xxx indicates the same digit dialled three times, and a, b, c and d may each be any of the ten digits)
0800 lines are used by companies, and it is the receiver and not the caller who pays for the call, so that potential clients are encouraged to contact business companies for free.
0810 lines are paid by the caller, but the cost is for a local call, even if you are calling from a different area. The remaining is covered by the receiver.
And 0600 numbers are special more expensive lines, that serve such purposes as TV games, fund collecting for charity companies, hot lines, etc. Basically a part of the extra money charged to the caller is sent to the owner of the line.
Often the abcd or even (xx)xabcd part of the number is chosen, if available, to form a word that is representative of the company holding the number.
Brazil
Brazil is divided into 67 two-digit geographical area codes, all of which with eight-digit numbers, in the format AA NNNN-NNNN, except for cell phones, which contain nine digits, usually in the format AA 9NNNN-NNNN.
Peru
Peru uses 2-digit area codes followed by 6-digit subscriber numbers outside of Lima. In Lima the area code is «1» and the subscriber number has 7 digits, divided XXX XXXX. The «trunk 0» is often used, especially for numbers outside Lima. For example, a phone number in Arequipa might be written (054) XX-XXXX.
Cellphone numbers used to have 8 digits with the first digit always being 9. In 2008 an additional digit was added to cellphone numbers, while land numbers remained the same. The previous convention for cell numbers in Lima was usually 9XXX XXXX, though 9-XXX XXXX was also used. With the new 9-digit number, the form 9XX XXX XXX is becoming increasingly common as opposed to 9 XXXX XXXX, 9X XXX XXXX or 9XXXX XXXX.
Outside Lima cellphone numbers used to be 9 followed by six digits, i.e., 9 XXX XXX. The 2008 changes were somewhat more complicated. In four departments (similar to states), a 2 digit code now has to be entered before the 9. In the example of Arequipa, the code of 95 has to be entered before the 9, so the new numeration is 959 XXX XXX. The other codes are 94 for La Libertad (Trujillo), 96 for Piura and 97 for Lambayeque (Chiclayo). In the other 19 rural departments, the 9 is followed by the department’s 2-digit area code then the 6-digit subscriber number. For example, the area code for Cusco is 84, so their new cellphone numeration is 984 XXX XXX. The effect is that all Peruvian cellphone numbers now have 9 digits; under the old system they had 8 digits in Lima and 7 everywhere else.[19]

National conventions for writing telephone numbers vary by country. While international standards exist in the form of recommendation E.123 by the sector ITU-T of the International Telecommunication Union (ITU), national telephone numbering plans define the format of telephone numbers assigned to telephones and similar communication endpoints.
The presentation of telephone numbers in this article does not include any international dialing codes necessary to route calls via international circuits. In examples, a numeric digit is used only if the digit is the same in every number, and letters to illustrate groups. X is used as a wildcard character to represent any digit in lists of numbers.
Africa
Djibouti
All telephone numbers in Djibouti are eight digits long.
Fixed line numbers start with 21 or 27, then a fixed line locality code, followed by four digits.
Mobile numbers start with 77, then a mobile line locality code, followed by four digits.
The international dialing code for Djibouti is +253, so the format becomes «+253 XX YY ZZ ZZ».
Morocco
All telephone numbers in Morocco are 10 digits long (initial 0 plus nine numbers).
Landline numbers start with 05, followed by two digits for the regional area RR, then two digits for the local area LL, then 4 digits for the subscriber number XX XX: («05 RR LL XX XX» or «05RR LL XX XX»).
Mobile numbers start with 06 or 07, followed by the subscriber number («06 XX XX XX XX» or «07 XX XX XX XX»).
The international dialing code for Morocco is +212, so the format becomes «+212 Y XX XX XX XX» or «+212 YXX XX XX XX», also «+212 YXX-XXXXXX» as well, where Y is 5 for landlines or 6/7 for mobile.
Free calling numbers (green numbers) or call center numbers start with 080 or 090.
Kenya
Telephone numbers in Kenya uses a 9 digit format. The 9 digits used for local calls start with a «0» (trunk prefix) for domestic calls, followed by the 3 digit area/provider code and the final 6 digits (07XX XXX XXX). The international code for Kenya is «+254».
South Africa
South Africa uses 10 digit dialling which has been required since 16 January 2007. The 10 digits used for local calls (AAA XXX XXXX or 0AA XXX XXXX) consist of a 3 digit area/type code (the first digit in the area/type code is a trunk prefix) followed by 7 digits. All area codes, including mobile numbers, start with a «0» (trunk prefix) for domestic calls. When dialing from another country, the international calling code for South Africa is «+27» with the rest of the digits excluding the «0» trunk prefix (+27 AA XXX XXXX).
Asia
China
Telephone numbers in China are 10 or 11 digits long (excluding an initial zero which is required at times) and fall in at least four distinct categories:
- Landlines: In China, the length of phone numbers varies from city to city. It is usually written as (0XXX) YYY YYYY (For landlines registered in large metropolises, it is written in the format (0XXX) YYYY YYYY), where 0 is the trunk code, XXX is the area code (2 or 3 digits) and YYYY YYYY is the local number (7 or 8 digits). For example, (0755) XXXX YYYY indicates a Shenzhen number. XXXXYYYY is dialed locally, 0755 XXXX YYYY is dialed in other areas inside the country, while, for international calls to Shenzhen, the 0 is dropped and is written +86 755 XXXX YYYY.
- Mobiles: The 11-digit code is always written in full in the whole China e.g. 1WX YYYY ZZZZ. Each WX is assigned to a service provider while W is usually ‘3’ through ‘9’. The remaining 8 digits are the subscriber number.
- Toll Free: These are usually ten digit numbers beginning with 800 or 400. 800 (toll-free) are accessible only when called from landline phones, while 400 (shared toll) are accessible from all phones. 400 XXX XXXX or 800 XXXX XXXX.
- Service numbers: These are usually 3- to 5-digit numbers (e.g. Police is 110) used to access an emergency service (Fire 119, Ambulance 120, Police 110, Roadside assistance 12122) or a value-added service.
Hong Kong and Macau
Every number, except special service numbers, is an 8-digit number; they are grouped as XXXX YYYY. There are no area codes.
India
Telephone numbers in India are 10 digits long (excluding an initial zero which is required at times) and fall in at least four distinct categories:
- Landlines: Written as AAA-BBBBBBB, where AAA is the Subscriber Trunk Dialing code (long distance code) and BBBBBBB is the phone number. The total length of the Subscriber Trunk Dialing code and the phone number is 10 digits. The Subscriber Trunk Dialing code can be from 2 digits (11 or 011) up to 4 digits long.
- Mobiles: Written as AAAAA-BBBBB for ease of remembering (though the prefix is either 2-digits or 4-digits in the numbering plan). Mobile numbers which are not local need to be prefixed by a 0 while dialing, or by +91 (91 is the country code for India). A mobile number written as +91-AAAAA BBBBB is valid throughout India, and in other countries where the + is recognized as a prefix to the country code. Since 2015, calls from mobile phones to any other mobiles do not need to prefix with a 0. However, calls from landlines to non-local mobile numbers need to be prefixed with 0.
- Toll Free: These are usually ten digit numbers beginning with 1-800. Sometimes they are accessible (or are toll-free) only when called from the government-owned telephone corporation, BSNL/MTNL.
- Service numbers: These are usually three or four digit numbers (e.g. Police is 100) used to access an emergency service (Fire, Ambulance, Police, Roadside assistance) or a value-added service.
Iran
All telephone numbers in Iran are 11 digits long (initial 0 plus ten numbers). The first two or three digits after the zero are the area code. The possibilities are: (0xx) xxxx xxxx (for landlines), 09xx xxx xxxx (for cellphones) and 099xx xxx xxx (for MVNO).
When making a call within the same landline area code, initial 0 plus the area code must be omitted.
An example for calling telephones in the city of Tehran is as follows:
- xxxx xxxx (within Tehran, via a landline)
- 021 xxxx xxxx (Outside Tehran, or via a cellphone)
- +98 21 xxxx xxxx (outside Iran)
An example for mobile numbers is as follows:
- 09xx xxx xxxx (in Iran)
- +98 9xx xxx xxxx (outside Iran)
Japan
The traditional convention for phone numbers is (0AA) NXX-XXXX, where 0AA is the area code and NXX-XXXX is the subscriber number. This number format is very similar to the North American numbering plan, but the country has a trunk code of 0 instead of 1, so international callers (using +81) do not have to dial the trunk code 0 when calling to Japan. Telephone numbers were 9 digits long in Tokyo and Osaka until the late 1990s, when a seventh digit was added to the subscriber number. Densely populated areas have shorter area codes, while rural areas have longer area codes, but the last two digits of a five digit long area code (including the first zero) may also be the first two digits of the subscriber number. Area codes increase from north to south, except in areas such as the western Hokuriku region and the prefecture of Okinawa, where area codes increase from west to east or south to north.
Some telephone numbers deviate from this rule:
- Toll-free dialing and Navi Dial operations (0120-XX-XXXX, 0570-XX-XXXX, or 0800-XX-XXXX), where XX-XXXX is the subscriber number
- The area code 050 uses an 11 digit phone number (050-XXXX-XXXX), where XXXX-XXXX is the subscriber number
- 110 and 119 are examples of three digit emergency numbers
Malaysia
All area codes including mobile start with a «0» (trunk prefix) for domestic calls. If you are dialing from another country the international calling code for Malaysia is «60» which may be confusing; do not dial an extra «0» before the rest of the digits. For fixed line and mobile phone numbers, a dash is written in between the area/mobile code and the subscriber number, with an optional space before the last four digits of the subscriber number. For example, a fixed line number in Kuala Lumpur is written as 03-XXXX YYYY or 03-XXXXYYYY, while a fixed line number in Kota Kinabalu is written as 088-XX YYYY or 088-XXYYYY. A typical mobile phone number is written as 01M-XXX YYYY or 01M-XXXYYYY. Toll-free and local charge numbers are written as 1-800-XX-YYYY and 1-300-XX-YYYY respectively, while premium rate numbers are written as 600-XX-YYYY.
Pakistan
Telephone numbers in Pakistan have two parts. Area codes in Pakistan are from two to five digits long; the smaller the city, the longer the prefix. All the large cities have two-digit codes.
Smaller towns have a six digit number. Large cities have seven-digit numbers. Azad Jammu and Kashmir has five digit numbers. On 1 July 2009, telephone numbers in Karachi and Lahore were changed from seven digits to eight digits. This was accomplished by adding the digit «9» to the beginning of any phone number that started with a «9» (government and semi-government connections), and adding the digit «3» to any phone numbers that did not start with the number «9».[1]
It is common to write phone numbers as (0xx) yyyyyyy, where xx is the area code. The 0 prefix is for trunk (long-distance) dialing from within the country. International callers should dial +92 xx yyyyyyyy.
All mobile phone codes are four digits long and start with 03xx. All mobile numbers are seven digits long, and denote the mobile provider on a nationwide basis and not geographic location. Thus all Telenor numbers (for example) nationwide carry mobile code 0345 etc.
Universal access number
- 111 xxx xxx
Emergency Service Numbers
- 1xx
- 1xxx
Premium Rate services:
- 0900 xxxxx
Toll free numbers (For callers within Pakistan):
- 0800 xxxxx
Philippines
Telephone numbers in the Philippines are written as +63 (XXX) YYY ZZZZ for international callers. For domestic calls, the country code (+63) is omitted and a trunk prefix (0) is placed[citation needed]. For local calls, both the 0 and area code are omitted. Mobile numbers are written as +63 (XXX) YYY ZZZZ or 0 (XXX) YYY ZZZZ.
Singapore
In Singapore, every phone number is written as +65-XXXX-YYYY or +65 XXXX YYYY.
Mobile phones starts with 8/9, landline phone numbers starts with 6 while VOIP numbers starts with 3.
Subscriber numbers have 8 digits and there are no area codes.
Sri Lanka
Except for short codes and emergency numbers, all telephone numbers in Sri Lanka are ten digits long (initial 0 + nine numbers).
Landline phone numbers begin with the area code, then one digit for the operator code, then six digits for the primary telephone number.
Format: (XXX Y ZZZZZZ) where:
- «xxx» denotes the area code. All area codes begin with the number 0.
- The operator code for fixed (landline) numbers is «y».
- «zzzzzz» denotes the primary telephone number, which has six digits.
Mobile numbers start with the mobile operator code (which begins from 07X, followed by seven digits for the main telephone number).
Format: (XXX ZZZZZZZ) where:
- When dialing a mobile number, «xxx» represents the mobile operator code. All mobile operator codes begin with the number 07.
- «zzzzzzz» represents the main telephone number of seven digits.
The international dialing code for Sri Lanka is +94, so the format becomes «+94 XX Y ZZZZZZ» for landlines and the format becomes «+94 XX ZZZZZZZ» for mobile numbers.[2]
South Korea
South Korean phone numbers can be as short as 7 digits and as long as 11 digits, because, when making a local call (i.e. in the same city), there is no need to dial the area code. South Korean area codes are assigned based on city.
Landline phone numbers
Landline home numbers are usually written as: 0XX-XXX-XXXX or (0XX) XXX-XXXX where 0XX indicates an area code. (0XX) XXX-XXX and 0XX XXX XXXX (without hyphens) are comprehensible as well. The area code may be two digits long for some cities such as Seoul and Gwacheon (these two cities use the same area code) and three digits for other cities such as Incheon, Busan and most of the cities in Gyeonggi-do. The middle three-digit part is extended to four digits in many areas due to the increased number of telephone users.
In the international context, 82 0XX-XXX-XXXX is commonly used as well. For international calls, «0» in the area code is often omitted, because it is not necessary to dial 0 from foreign countries. Therefore, it is better written as: 82-(0)XX-XXX-XXXX or 82-(0)XX-XXXX-XXXX The plus (+) sign is often added to the country code too (e.g., +82 0XX-XXX-XXXX or +82-0XX-XXXX-XXXX).
Mobile phone numbers
For mobile numbers, 016490641 so on. As with the landline home numbers, the mobile numbers’ middle three-digit part is extended to four digits (e.g., 016490641) due to the increased number of mobile phone users.
Business numbers
If a number starts with 070, the number does not belong to any particular area, and is a number given by an Internet telephone service. In this case, 070 is not usually put in the brackets, neither ( ) nor ).
In the business context, the numbers in the format of 15XX-XXXX and 16XX-XXXX are business representative agency or customer services. While the numbers starting with 080 (e.g., 080-XXX-XXXX) are also business-related numbers but are usually toll-free customer service centers. Also in this case, 15XX, 16XX or 070 are not put in the brackets, neither ( ) nor ).
National service numbers
There are national telephone services which have phone numbers in the format of 1XX or 1XXX, without any area code. For example, 114 is for telephone yellow page, 119 is for fire/emergency number, 112 is for police station center, 131 is for weather forecast information, 1333 is for traffic information, and so on. The number 111 is for reporting spies, especially from North Korea. It used to be 113, so most of senior citizen still believe it is the number for reporting spies. These numbers do not need any brackets.
Alternative numbers
If there are multiple numbers used for one person/entity, the symbol «~» is usually used to avoid repetitions. For example, if one company has three phone numbers—031-111-1111, 031-111-1112 and 031-111-1113—then they are shortened as in 031-111-1111~3.
If the numbers are not consecutive, then the last digit is written together with commas. For example, if a company has three numbers—031-111-1111, 031-111-1115, 031-111-1119, then they are shortened as in 031-111-1111, 5, 9.
Taiwan
Landline numbers in Taiwan are written with the area code in parenthesis [with phone numbers total 9 digits]
Example: (02) XXXX YYYY for phone numbers in Taipei area.
Mobile phones have 3 digit «company code» assigned to different mobile service carriers such as (09**) XXXXXX followed by a 6 digit phone number.
(note: Mobile carriers could have multiple company codes)
Thailand
All numbers in Thailand, whether for landlines or mobile reception, consist of eight digits, xxxx xxxx in the government’s official format. When calling domestically, landline numbers are preceded by a zero (0 xxxx xxxx, example 0 5381 0595) while mobile numbers are preceded by 0 plus one digit (0x xxxx xxxx, example 06 9756 4509). Thais often confuse the current numbering system with the old provincial area code system, which no longer exists as area codes were integrated into all phone numbers in 2005. Because of this, unofficially people often write numbers as 0xx xxx xxx (053 810 595). Calling a Thai phone number from outside Thailand, one drops the 0 and adds the +66 country code. Example +66 5381 0595.[3]
Oceania
Australia
Most Australian telephone numbers are 10 digits long, and are generally written 0A BBBB BBBB or 04XX XXX XXX for mobile telephone numbers, where 0A is the optional «area code» (2,3,7,8) and BBBB BBBB is the subscriber number. (http://www.acma.gov.au/Industry/Telco/Numbering/Numbering-Plan/phone-number-meanings-numbering-i-acma)
When the number is to be seen by an international audience, it is written +61 A BBBB BBBB or +61 4XX XXX XXX. When written for a local audience, the optional area code is omitted. The area code is often written within parentheses (0A) BBBB BBBB. Mobile numbers should never have parentheses.
Ten-digit non-geographic numbers beginning with 1 are written 1X0Y BBB BBB, where X = 8 for toll free numbers, X = 3 for fixed-fee numbers and X = 9 for premium services. Six-digit non-geographic numbers are written 13 BB BB or 13B BBB; these are fixed-fee numbers. Seven-digit 180 BBBB numbers also exist. ‘B’s are sometimes written as letters.
New Zealand
Almost all New Zealand telephone numbers are seven digits long, with a single-digit access code and a single-digit area code for long-distance domestic calls. Traditionally, the number was given as (0A) BBB-BBBB, with the two first digits (the STD code) often omitted for local calls. The brackets and the dash are also often omitted. Mobile numbers follow the same format, but with the area code being two digits, i.e. (02M) BBB-BBBB. ( Some mobile numbers are longer: (021)02BBBBBB, (021)08BBBBBB, (020)40BBBBBB, (020) 41BBBBBB and (028) 25BBBBBB; and some are shorter: (021)3BBBBB, (021)4BBBBB, (021)5BBBBB, (021)6BBBBB, (021)7BBBBB, (021)8BBBBB and (021)9BBBBB)
There are also free-phone numbers (starting with 0800 or 0508) that are given in the format 0800-AAA-AAA. It is not uncommon for the 0800 and 0508 to be enclosed in brackets, although this is not strictly correct as the brackets denote optional parts of the number, and the 0800 and 0508 is required.[4]
Recently with 8 digit mobile numbers becoming more common the prefix-4 digits-4 digits format has been adopted for readability: 022 1234 5678.
For international use, the prefix +64 is substituted for the leading zero, giving +64-A-BBB-BBBB for land-lines, and +64-MM-BBB-BBBB for mobile numbers.
Europe
Belgium
Belgian telephone numbers consist of two major parts: Firstly ‘0’, secondly the «zone prefix» (A) which is 1 or 2 digits long for landlines and 3 digits long for mobile phones and thirdly the «subscriber’s number» (B).
Land lines are always 9 digits long. They are prefixed by a zero, followed by the zone prefix. Depending on the length of the zone prefix, the subscriber’s number consists of either 6 or 7 digits. Hence land line numbers are written either 0AA BB BB BB or 0A BBB BB BB.
Mobile phone numbers always consist of 10 digits. The first digit of the «zone prefix» of a mobile number is always ‘4’. Then follows 2 digits indicating to which Mobile Operator’s pool the number originally belonged when it was taken into usage. The fourth digit represents a «sub-group» of this pool and has no additional meaning other than increasing the amount of possible numbers. The subscriber’s number consists of 6 digits. Hence, mobile phone numbers are written 04AA BB BB BB. Sometimes, the last 6 digits are written in two groups of 3 digits to increase readability: 04AA BBB BBB.
Numbers are sometimes written with a slash in between the zone prefix and the subscriber’s number. This is the case for both land lines and mobile phone numbers. Sometimes, dots are written between the blocks of the subscriber’s number. Examples: 0AA/BB BB BB, 0AA/BB.BB.BB; for mobile numbers: 04AA/BB BB BB, 04AA/BB.BB.BB or 04AA/BBB.BBB.
The international code prefix for Belgium is «+32». When dialing a number with the prefix, the 0 can be dropped, e.g.: +32 9055.
Denmark
Danish telephone numbers are eight digits long and are normally written
- in four groups of two digits each, with the groups separated by spaces: AA AA AA AA,
- in two groups of four digits each, with the groups separated by a space: AAAA AAAA,
- in one group of two digits followed by two groups of three digits each, with the groups separated by spaces: AA AAA AAA, or
- all in one go: AAAAAAAA.
The third option, AA AAA AAA is not commonly used for personal (landline or mobile) numbers, but is mostly found in corporate numbers, especially in advertizing. The standard formats – which when spoken divide numbers into ranges from 00 (zero zero) to 99 (ninety-nine) – limit the possible range of the ability to create telephone numbers that are easy to remember; dividing the numbers into groups of three expands the mnemonic possibilities.
Danish emergency and service numbers are three digits long and are written AAA. Danish short numbers used for text messaging services are four digits long and are written AAAA.
Finland
France
French telephone numbers are 10 digits long, usually written in groups of two separated by spaces, in the format 0A BB BB BB BB where 0 (the trunk prefix) was created in 1996 to be a carrier selection code, and A is the «territorial area code» included in the subscriber number A BB BB BB BB.
Sometimes, it is also written in the format 0A.BB.BB.BB.BB using periods instead of spaces, but this is less common.
The A (territorial area code) can be 1 to 5 (for geographic-based numbers, according to location: Paris/Suburbs, northwest France, northeast France, southeast France, and southwest France, respectively), and it designates nationwide numbers when it is 6 or 7 (mobile numbers), 8 (special numbers), or 9 (phone over IP over xDSL/non-geographic numbers).
The numbering plan is a closed one; all digits must always be dialed.
The first two or three B can designate the area (old area code) for geographic numbers, or the operator to whom the number resource belongs.
There are also «short numbers» for emergencies (such as 112), that are written 1C or 1CC; and short numbers for special services, written 10 CC, 11C CCC, or 36 CC. 00 is the international access code.
International format is +33 A BB BB BB BB where the leading trunk prefix 0 disappears (it must not be dialed from abroad). This format can be directly used in mobile phones.
Germany
German telephone numbers have no fixed length for area code and subscriber number (an open numbering plan).
There are many ways to format a telephone number in Germany. The most prominent is DIN 5008 but the international format E.123 and Microsoft’s canonical address format are also very common.
Trunk access code is 0 and international call prefix code is 00.
Form | Example |
---|---|
DIN 5008 | 0AAAA BBBBBB |
DIN 5008 with Extension | 0AAAA BBBBBB-XX |
DIN 5008 international | +49 AAAA BBBBBB |
E.123 local | (0AAAA) BBBBBB |
E.123 international | +49 AAAA BBBBBB |
Microsoft | +49 (AAAA) BBBBBB |
Old | 0AAAA-BBBBBB |
Very old | 0AAAA/BBBBBB-XX |
Numbers are often written in blocks of two. Example: +49 (A AA) B BB BB (Note the blocks go from right to left)
The very old format and E.123 local form are often used by older people but also for technical reasons.
Greece
Greek telephone numbers are ten digits long, and usually written AAB BBBBBBB or AAAB BBBBBB where AAB or AAAB is the 2- or 3-digit national area code plus the first digit of the subscriber number, and BBBBBBB or BBBBBB are the remaining digits of the subscriber number. The entire number must always be dialed, even if calling within the same local area; therefore, the national destination code is not separated from the subscriber number. According to international convention, numbers are sometimes written +30 AAB BBBBBBB or +30 AAAB BBBBBB to include the country calling code.
Hungary
In Hungary the standard lengths for area codes is two, except for Budapest (the capital), which has the area code 1. Subscribers’ numbers are six digits long in general. Numbers in Budapest and cell phone numbers are seven digits long.
Iceland
Phone numbers in Iceland are seven digits long and generally written in the form XXX XXXX or XXX-XXXX.
Ireland
Phone numbers in Ireland are part of an open numbering plan with varying number lengths. The area code system similar to some other northern European countries. Unlike the UK, Irish fixed line numbering is divided into a number of regions which are (except Dublin) further subdivided in a hierarchical structure, with the largest town often (but not always) taking 0A1.
Area codes start with a trunk prefix «0» and extend for up to four digits but usually 3; followed by the local phone number of up to seven digits.
In industry jargon, these area codes and prefixes are referred to as NDCs (National Dialing Codes). This is the term used by ComReg and technical documents, as they include non-geographic codes. Historically, like the UK, the term STD code (Subscriber Trunk Dialling) was used.
However, the terminology is archaic and is no longer universally understood and should not be used to avoid confusion.
Dublin uses the shorter (01) code which is not further subdivided. Other cities and major towns usually have codes ending in 1. Cork for example is 021, Galway 091, Limerick 061 etc.
The leading zero is always omitted when dialling from outside the country.
Local phone numbers are either 5, 6 or 7-digits long. In 7-digit numbering they are usually grouped as BBB BBBB, 6-digit numbers are grouped BBB BBB and 5-digit numbers are normally all grouped together BBBBB
Grouping of numbers is not strictly adhered to, but usually fairly consistent. The area code should always be kept separated with a space or surrounded by brackets and not merged into the local number.
The use of hyphens is discouraged, particularly on websites as it can prevent mobile browsers identifying the number as a clickable link for easier dialling.
Fixed line numbers are normally presented as follows:
- 01 BBB BBBB for a Dublin number (7 digit)
- 021 BBB BBBB for a Cork number (7 digit)
- 064 BBB BBBB for a Killarney number (7 digit)
- 061 BBB BBB for a Limerick number (6 digit)
- 098 BBBBB for a Westport number (5 digit)
- 0404 BBBBB for a Wicklow number (5 digit)
Area codes may also be surrounded by brackets, but this practice is falling out of use, as local dialing without the area code is optional on landlines and the area code must always be dialled on mobile phones.
The Irish telecommunication regulator, ComReg has been gradually rationalising area codes by merging and extending local numbering to 7-digits in the format 0AA BBB BBBB. This is being carried out only where necessary to avoid disruption. This means that varying fixed line number lengths will continue to exist in Ireland for the foreseeable future.
Mobile numbers are presented as follows:
08A BBB BBBB
Brackets should not be used around the mobile prefix as it is never optional and must always be dialled, even from another phone with the same prefix.
Special rate numbers, such as free phone/toll free and premium rate are usually grouped:
Freephone: 1800 BB BB BB or (spoken as one-eight-hundred)
Local rate: 1850 BB BB BB (eighteen-fifty)
1550 BB BB BB (read as fifteen-fifty)
However, for memorability, this is not consistently adhered to.
Alphanumeric characters can also be used in presenting numbers for added memorability, but it is much less common than in North America
For example:
18AA 99 TAXI
Note: These special rate numbers are not reachable from outside Ireland and should never be presented as +353 1800 or +353 1550 etc. as this would result in a connection to an unrelated Dublin landline in the +353 1 BBB BBBB range.

Italy
Phone numbers in Italy have variable length. There’s no well established convention about how to group digits or which symbol to use, but this is hardly an issue since all the digits are always dialed.
Netherlands
Since 10 October 1995 (Operation Decibel) all telephone numbers in the Netherlands are 10 digits long (including the trunk prefix ‘0’). The area code (‘A’) is commonly separated with a dash (‘-‘) and sometimes a space from the subscriber’s number (‘B’). Alternatively, the area code (including the trunk prefix) can be enclosed in parentheses.
The length of the area code for landlines is either 2 or 3 digits, depending on the population density of the area. This leaves 7 or 6 digits for the subscriber’s number, resulting in a format of either 0AA-BBBBBBB or 0AAA-BBBBBB. Cellphone numbers are assigned the 1-digit area code 6, leaving 8 digits for the subscriber’s number: 06-CBBBBBBB, where subscriber’s number (‘C’) is neither 6 nor 7. Service numbers (area codes 800, 900, 906 and 909) have either 4 or 7 remaining digits, making them 8 or 11 digits in total: 0AAA-BBBB or 0AAA-BBBBBBB. The area code 14 has no trunk prefix and is used for government numbers, currently only for municipalities. The remaining digits represent the area code of the municipality. Therefore, the length 14 numbers total either 5 or 6 digits: 14 0AA or 14 0AAA
The trunk prefix ‘0’ is dropped when prefixed by the country code: +31 AA BBBBBBBB, +31 6 CBBBBBBB, etcetera. Note that there is not a trunk prefix for the 14 series so the international number becomes +31 14 0AAA.
Norway
Norwegian telephone numbers are 8 digits long. A number to a fixed line is written in four groups of two separated by spaces, AA AA AA AA. Phone numbers in 8xx series is written in three groups, AAA AA AAA. This makes it easy to determine if the B-number is SMS capable. Mobile numbers start with 4 or 9.
Poland
Telephone numbers in Poland are 9 digits long. For mobile phones, the preferred format is AAA-AAA-AAA. For landline phones, the preferred format is AA-BBB-BB-BB, where AA is area code. Occasionally, you can encounter numbers formatted as (AA) BBB-BB-BB. Omitting area code is not permitted, because nowadays it is always required.
Portugal
Telephone numbers in Portugal Country code +351 are 9 digits long. According to present day a number to a fixed line is written in three groups of two separated by spaces, AAA AAA AAA. Cellphone numbers are written in three groups, AAA AAA AAA. Mobile numbers start with 9.
Romania
Starting with 2002 phone numbers in Romania are 10 digits long, the first digit always being 0. The preferred format is AAAA-AAA-AAA for mobile, except for landline phones in Bucharest where the preferred format is AAA-AAA-AA-AA.
Russia
Russia has an open numbering plan with 10-digit phone numbers. Trunk prefix is 8 (or 8~CC when using alternative operators, where CC is 21–23, 52–55). International call prefix is 8~10 (or 8~CC when using alternative operators, where CC is 26–29, 56–59). The country code is +7.
Length of geographical area codes (A) is usually 3 to 5 digits; length of non-geographical area codes is 3. The groups of digits in the local subscriber’s number (B) are separated by dashes (‘-‘): BBB-BB-BB, BB-BB-BB, B-BB-BB. The area code is included in parentheses, similarly to E.123 local notation: (AAA) BBB-BB-BB, (AAAA) BB-BB-BB, (AAAAA) B-BB-BB.
Area code dialing is optional in most geographical area codes, except Moscow (area codes 495, 498, 499); it is mandatory for non-geographical area codes. E.123 international and Microsoft formats are used for writing local phone numbers as well; international prefix and country code +7 are replaced with trunk code 8 (or 8~CC) when dialing a mandatory area code.
Even though trunk code is not needed for calls within the same geographical area, recent convention adds the default trunk code to the phone number notation: 8 (AAAA) BB-BB-BB. For mandatory area code dealing plans, notation 8 AAAA BB-BB-BB is used. These formats are a mix of Microsoft format and E.123 local notation.
Mobile phones require full 10-digit number which starts with 3-digit non-geographical area codes 900–990. For international calls abroad or international roaming calls to Russia, E.123 international notation with an international call prefix ‘+’ is the only allowed calling number format. For local calls both 8 and +7 are accepted as a trunk code.
Form | Example |
---|---|
Old | BBB-BB-BB |
Old with area code | (AAA) BBB-BB-BB |
Conventional | 8 (AAA) BBB-BB-BB |
Microsoft | +7 (AAA) BBB-BB-BB |
Conventional (mandatory area code) | 8 AAA BBB-BB-BB |
E.123 international | +7 AAA BBB BB BB |
Spain
Spanish telephone numbers are nine digits long, starting with ‘9’ or ‘8’ for fixed lines (excluding ’90x’ and ’80x’) or with ‘6’ or ‘7’ for mobile phones.
The first group in fixed lines always identifies the dialed province. That group might be of 2 or 3 digits; for example, 91 and 81 are for Madrid while 925 and 825 are for Toledo. The second group is always of 3 digits as it formerly identified the telephone exchange (it now identifies the telephone area).
When the first group is 2 digits long (as in Madrid), the number is usually written in four groups of 2-3-2-2 digits (AB CCC DD DD)
When the first group is 3 digits long (as in Toledo), the number is usually written in 3 groups of 3 digits (ABB CCC DDD) but the form 3-2-2-2 (ABB CC CD DD) is not uncommon.
Mobile numbers are usually grouped by threes, ABB CCC CCC, but the form 3-2-2-2 is also seen.
Sweden
Swedish telephone numbers are between eight and ten digits long. They start with a two to four digit area code. A three digit code starting with 07 indicates that the number is for a mobile phone. All national numbers start with one leading 0, and international calls are specified by 00 or +. The numbers are written with the area code followed by a hyphen, and then two to three groups of digits separated by spaces.[6]
Type | Format |
---|---|
National 10 digit | 0A-XXX XXX XX or 0AA-XXX XX XX or 0AAA-XX XX XX |
National 9 digit | 0A-XXX XX XX or 0AA-XX XX XX or 0AAA-XXX XX |
National 8 digit | 0A-XX XX XX or 0AA-XXX XX |
Mobile 10 digit | 07A-XXX XX XX or 07AA-XX XX XX |
International | +CC AAA-XXX XX XX or 00CC AAA-XXX XX XX |
Switzerland
Swiss telephone numbers are ten digits long, and usually written 0AA BBB BB BB where 0AA is the national destination code and BBB BB BB is the subscriber number. The entire number must always be dialed, including the leading 0, even if calling within a local area, therefore the national destination code is not separated from the subscriber number. According to international convention, numbers are sometimes written +41 AA BBB BB BB to include the country calling code. Certain nationwide destination codes, such as for toll-free or premium-rate telephone numbers, are written 0800 BBB BBB or 0900 BBB BBB. Short numbers are used for emergency services such as 112 that are written 1CC or 1CCC.
Turkey
In Turkey the format for telephone numbers is commonly seen as 0BBB AAA AA AA. While landline numbers having the prefix 02BB AAA AA AA, 03BB AAA AA AA, or 04BB AAA AA AA[7] mobile numbers have the prefix 05BB AAA AA AA. Landline area codes are separated by cities and only one city, Istanbul, has two area codes: 216 for the Asian side, and 212 for the European side. Mobile numbers however are separated by carriers. There are three mobile carriers in Turkey: Vodafone TR, Turkcell and Turk Telekom. Turkcell has the prefix 053B AAA AA AA, Vodafone TR has the prefix 054B AAA AA AA, and Turk Telekom has the prefix 055B AAA AA AA.
Since 9 November 2008, with the passing of the Number Carriability Regulation by ICTA, mobile numbers can be carried from one mobile carrier to the other, without having to change the prefix.[8] This caused dialing 05BB to call another number on the same carrier to become mandatory. Calls to numbers which were carried to another operator are signaled by a unique sound upon dialing, to signify that the recipient is on another network and alert them against potentially unwanted interconnection charges. The same regulation passed on 10 September 2009 regarding landline numbers, without the requirement to dial the prefix among numbers with the same geographical area, sharing the same prefix.
The «0» on every prefix is an Area Code Exit code that must be dialed when a number with a different area code is being called. So when calling from outside of Turkey those 0s are not dialed. The dialing format when calling from outside Turkey is +90 BBB AAA AA AA and NOT +90 0BBB AAA AA AA. Unlike the North American system, the Country Exit Code isn’t 011 but 00. So it is one «0» to exit area and one more «0» to exit the country.
Ukraine
There are many recommendations for recording phone numbers. The most common in the world is Recommendation E.123 E.123 International Telecommunication Union[9]
and the standard format for Microsoft telephone numbers Microsoft.[10]
There is an international format for recording a telephone number containing the country code, settlement code and telephone number, and the national format containing the settlement code and telephone number.
To record Ukrainian telephone numbers, it should be remembered that the country code for Ukraine is: +380, telephone codes for settlements do not have an initial zero, long-distance prefix: 0.
Writing telephone numbers | |
Phone number | Note |
+380 44 123 45 67 | E.123, international format: country code, settlement code and telephone number are separated by spaces |
(044) 123 45 67 | E.123, national format: long-distance prefix and city code in parentheses (national format: long-distance prefix and settlement code in parentheses due to possible confusion needs constant additional clarification), п. 2.8 [9] ), the phone number is separated from the code and separated by spaces |
+380 (44) 1234567 | Microsoft, international format: country code, space code, settlement code in brackets, space code, telephone number. |
Often, they mistakenly write down phone numbers, transferring the last zero from the country code to the settlement code, for example:+38 044 1234567 or +38 (044) 1234567. Such entry is incorrect because the telephone code of Ukraine is +380, and the codes of settlements or codes of mobile networks cannot begin with “0” or “1”.
United Kingdom
Dialling codes, also known as «area codes» are optional for local callers (often surrounded by parentheses, or separated with a dash), though there are trials running to make them mandatory,[11] and are followed by the customer’s telephone number.
Codes with the form 02x are followed by 8-digit local numbers and are usually written as 02x AAAA AAAA or (02x) AAAA AAAA. Area codes with the form 011x or 01×1 are used for many of the major population centres in the UK, are always followed by 7-digit local numbers and are usually written as 01xx AAA BBBB, (01xx) AAA BBBB or 01×1-AAA BBBB (the latter formerly the recommended format for six major metropolitan areas in the UK). Other area codes have the form 01xxx with 5 or 6 figure local numbers written as 01xxx or (01xxx) followed by subscriber number AAAAA or AAAAAA; or have the form 01xx xx with 4 or 5 figure local numbers written as 01xx xx or (01xx xx) followed by subscriber number AAAA or AAAAA.
Numbers for mobile phones and pagers are formatted as 07AAA BBBBBB and most other non-geographic numbers are 10 figures in length (excluding trunk digit ‘0’) and formatted as 0AAA BBB BBBB. However, these numbers are sometimes written in other formats. 9 figure freephone numbers are 0500 AAAAAA and 0800 AAAAAA and there is one number of 8 figures length: 0800 1111 (Childline).
Domestically, there are also a number of special service numbers such as 100 for the operator, 123 for the speaking clock and 155 for the international operator, as well as 118 AAA for various directory enquiry services, and 116 AAA for various helplines. For some services, the number you call will depend on which operator you use to connect the call. 112 and 999 work for calling the emergency services. These numbers cannot be called from abroad.
When calling from abroad, the initial ‘0’ trunk prefix is not required; it is, however, commonplace to represent telephone numbers with both the international code and the ‘0’ trunk prefix — which is typically placed within parentheses — but this representation is inconsistent with the E.123 international standard.[12]
North America
United States, Canada, and other NANP countries
Twenty-four countries and territories share the North American Numbering Plan (NANP), with a single country code, 1. The formatting convention for telephone numbers is NPA-NXX-XXXX, where NPA is the three-digit area code, and NXX-XXXX is the seven-digit subscriber number.[13]
NPA has the same syntax of NXX since the implementation of interchangeable area codes in 1995. The prefix NXX of the subscriber number is a code for the central office, unique in the numbering plan area. The place holder N stands for the digits 2 to 9, as the subscriber number may not begin with the digits 0 and 1. It is a closed telephone numbering plan in which all subscriber telephone numbers have seven digits, in addition to the three-digit area code.
Under all-number calling, a numbering plan introduced around 1960, local calls within an area code were placed by dialing NXX-XXXX, omitting the area code, known as seven-digit dialing. Only calling a destination in a different area code required dialing the destination area code, known as ten-digit dialing. Due to the need for a larger telephone number pool in many regions, seven-digit dialing is becoming rare in the United States. With the rapid growth of telephony in the late 20th century, many metropolitan areas saw the introduction of additional area codes. Multiple area codes were assigned to the same numbering plan area, a configuration known as an overlay numbering plan. Calls within an overlay are still local calls, despite the need for ten-digit dialing.
In general, placing long-distance calls requires dialing the trunk code 1, but this may be optional in some areas.
Canada
Canada is a member of the North American Numbering Plan, but administers its numbering resources individually, under guidance from the NANP Administrator. The Canadian government has stated on its Language Portal of Canada that telephone numbers are to be written with a hyphen between each sequence, as follows: 1-NPA-NXX-XXXX or NPA-NXX-XXXX.[14] 10-digit dialing is now required throughout most of Canada, including all of British Columbia, Alberta, Saskatchewan, Manitoba, Quebec, Nova Scotia, and Prince Edward Island, as well as most of Ontario. Areas not yet requiring 10-digit dialing are Ontario’s 807 area code, Newfoundland, New Brunswick, the Yukon, Northwest Territories, and Nunavut, although 10-digit dialing may be accepted in some of these areas.
In the province of Québec, where French is the first language, the Office québécois de la langue française has established that telephone numbers must be written with spaces first and then a hyphen for the last sequence, as follows: 1 NPA NXX-XXXX.[15] Educational institutions of Quebec will mark improperly written telephone numbers as orthographical mistakes in academic texts.[citation needed]
Mexico
Mexican telephone numbers have ten digits. They can consist of a two-digit (NN) area code and an eight-digit local number (ABCD XXXX) or a three-digit area code (NNN) with a seven-digit local number (ABC XXXX).
As of August 3, 2019 all the indicators and access codes (01, 044, 045) are deprecated, therefore all telephone numbers, for landline or mobile service, are dialed with ten digits.[16]
The formatting convention of a telephone number is
- ABCD XXXX or NN ABCD XXXX or (NN) ABCD-XXXX
- ABC XX XX or NNN ABC XXXX or (NNN) ABC-XX-XX
The international country code prefix for Mexico is 52. When dialing a number it must be formatted as «plus sign + country code + 10-digit number» e.g.: +52 NNN ABC XXXX
Central America
Some Central American countries write the country code for their own and other Central American countries in parentheses, instead of using a + sign, as recommended by E.123. For example, for a number in Costa Rica they would write (506) 2222-2222 instead of +506 2222-2222. On the other hand, Guatemala does have the custom of using the + sign. It is quite common for Central American businesses to write the whole phone number, including the country code in parentheses, on business cards, signs, stationery, etc.
Costa Rica
Costa Rican telephone numbers are 8 digits long, and are usually written in the format 2NNN-NNNN (for landlines), 8NNN-NNNN (for mobile telephone numbers from local telephone company ICE), 6NNN-NNNN (for mobile telephone numbers from Movistar) and 7NNN-NNNN (for mobile phone numbers from Claro).[17] Toll-free numbers use the format 800-NNN-NNNN and premium-rate telephone numbers are written 90x-NNN-NNNN where x varies according to the type of service offered. There are also «short numbers» for emergencies such as 911.
When Costa Rica switched from 7 to 8 digit numbers, it used a scheme similar to the 8 digit number scheme already in place in El Salvador at that time.
El Salvador
El Salvadoran telephone numbers are 8 digits long, usually written in the format 2NNN-NNNN (for landline use) and 7NNN-NNNN (for mobile telephone numbers). Premium-rate numbers start with a 9.
Guatemala
Guatemalan telephone numbers are 8 digits long and written in the format 2NNN-NNNN for landlines in Guatemala City, 6NNN-NNNN for landlines for the rest of municipalities in the Guatemala Department, and 7NNN-NNNN for landlines in Rural Guatemala / rest of country. Non-geographic numbers (mobile) are 5NNN-NNNN, 4NNN-NNNN, and 3NNN-NNNN. Within each area, there are different service providers. The following 3 digits indicate the service provider. However, their assignment is on a first-come first-served basis.
Additionally there are special numbers with the following conventions: 3 digit numbers for emergency systems, four digit numbers, 15NN for information and governmental institutions and 17NN for commercial and banking institutions with a high call influx, 6 digit numbers for Telephone carriers numbers and making operator assisted calls, collect calls. These calls are billed at different rates. 1-800: Toll-free calls redirected to out of country offices and 1-801: Local toll-free calls.[18]
Honduras
Honduran telephone numbers have either 7 digits (for landlines), which are usually written NNN-NNNN, or 8 digits (for mobile numbers), which are written NNNN-NNNN. The fact that landline and mobile numbers are different lengths sometimes causes confusion.
In 2010, an additional digit (2) was added to the start of land line numbers, thus standardizing the length at 8 digits.
South America
Argentina
Argentine telephone numbers always consist of 11 digits, including the geographical area code.
Area code
The area code can have 3, 4 or 5 digits, the first being always 0 (indicative of long distance calls). Moreover, in 1999 the whole country (except Buenos Aires, and Greater Buenos Aires) was divided into two zones. Roughly and with exceptions, one includes most of the northern half of the country; and the other, most of the southern half, though the actual reason for this division is not geographical, but the fact that each zone is administered by a different company.
So, the second digit of area codes can be 1 (only in Buenos Aires and Greater Buenos Aires code «011») or else a 2 (for towns in the southern half of the country) or a 3 (for the northern half). For example, (011) for Buenos Aires, (0341) for Rosario, (02627) for San Rafael. And the subscriber’s number will accordingly have 6, 7 or 8 digits, to complete the eleven digits.
Phone numbers are mostly written as:
- (011) xxxx-xxxx (Note that only the (011) code has 3 digits),
- (0xxx) xxx-xxxx or
- (0xxxx) xx-xxxx
The area code is usually written between brackets.
Subscriber number
In 1999, a general reform was introduced to telephone numbers, including the 1, 2 and 3 for area codes as explained above, and adding a 4 at the beginning of all subscriber’s numbers. However, since the reform some local numbers starting with a 5 are beginning to appear. Moreover, a hyphen is usually placed to separate the last four digits. Code areas do not usually include one single city or town, but several neighbouring towns. So, the part before the hyphen (called a prefix) is usually indicative of either a town within the code area, or even of a part of a larger city, which is assigned several prefixes. As a matter of fact, each area code has only a limited number of prefixes assigned, and these are locally limited within the area.
For example, the (0342) area has numbers with a 456- prefix, mostly located in the centre of Santa Fe. It also has numbers with a 460- prefix, usually for phone lines in the north east of the city. And there are lines with a 474- prefix, located in Santo Tomé. But no 444- prefix exists within this area. As for the part after the hyphen, it may usually be any succession of four digits, though sometimes a prefix is shared by two or more small towns, and then, the first digit after the hyphen carries the distinction between towns.
Sometimes, a prefix is reserved for official numbers, that is for offices depending on the national, provincial or local state. In the (0342) area, this is 457-, and phones within this prefix communicate with each other, by simply dialing the four final digits, though from other phones the prefix must be dialled as well.
Mobile phones
Mobile phones use the same area codes as landline telephones, but the number begins with a «15», added to a string of 6, 7 or 8 digits, just as described above. After the «15», the remainder of the number can start with a 3, a 4, a 5 or a 6. This «15» may be dropped when a call is made to a mobile phone in a different code area. And when sending text messages, the receiver’s number is best dialled both without the «15» and with the long distance code, even if both sender and receiver share a code area, but without the initial «0».
To sum up, given the mobile phone (011) 154-123-4567, you will call it by dialing:
- 154-123-4567 (within the same code area),
- (011) [15]4-123-4567 (from a different code area, including or omitting the 15),
And you will send messages to:
- 11 4-123-4567 (even when your phone has also a 011 number).
Special numbers
Two sorts of special numbers exist in Argentina. On the one hand, three-digit numbers are used for special services such as to call the police, fire brigade or emergency doctors, as well as to hear the official time. Also telephone companies have three-digit numbers to report a problem in the lines, or to ask for another subscriber’s number, when a paper directory is not available.
Additionally, there are other longer numbers. These include (but are not limited to):
- 0800 xxx abcd
- 0810 xxx abcd
- 0600 xxx abcd
(where the xxx indicates the same digit dialled three times, and a, b, c and d may each be any of the ten digits)
0800 lines are used by companies, and it is the receiver and not the caller who pays for the call, so that potential clients are encouraged to contact business companies for free.
0810 lines are paid by the caller, but the cost is for a local call, even if you are calling from a different area. The remaining is covered by the receiver.
And 0600 numbers are special more expensive lines, that serve such purposes as TV games, fund collecting for charity companies, hot lines, etc. Basically a part of the extra money charged to the caller is sent to the owner of the line.
Often the abcd or even (xx)xabcd part of the number is chosen, if available, to form a word that is representative of the company holding the number.
Brazil
Brazil is divided into 67 two-digit geographical area codes, all of which with eight-digit numbers, in the format AA NNNN-NNNN, except for cell phones, which contain nine digits, usually in the format AA 9NNNN-NNNN.
Peru
Peru uses 2-digit area codes followed by 6-digit subscriber numbers outside of Lima. In Lima the area code is «1» and the subscriber number has 7 digits, divided XXX XXXX. The «trunk 0» is often used, especially for numbers outside Lima. For example, a phone number in Arequipa might be written (054) XX-XXXX.
Cellphone numbers used to have 8 digits with the first digit always being 9. In 2008 an additional digit was added to cellphone numbers, while land numbers remained the same. The previous convention for cell numbers in Lima was usually 9XXX XXXX, though 9-XXX XXXX was also used. With the new 9-digit number, the form 9XX XXX XXX is becoming increasingly common as opposed to 9 XXXX XXXX, 9X XXX XXXX or 9XXXX XXXX.
Outside Lima cellphone numbers used to be 9 followed by six digits, i.e., 9 XXX XXX. The 2008 changes were somewhat more complicated. In four departments (similar to states), a 2 digit code now has to be entered before the 9. In the example of Arequipa, the code of 95 has to be entered before the 9, so the new numeration is 959 XXX XXX. The other codes are 94 for La Libertad (Trujillo), 96 for Piura and 97 for Lambayeque (Chiclayo). In the other 19 rural departments, the 9 is followed by the department’s 2-digit area code then the 6-digit subscriber number. For example, the area code for Cusco is 84, so their new cellphone numeration is 984 XXX XXX. The effect is that all Peruvian cellphone numbers now have 9 digits; under the old system they had 8 digits in Lima and 7 everywhere else.[19]

Известно, что первые слова, сказанные по телефону 10 марта 1876 года, принадлежат шотландскому изобретателю Александру Грэму Беллу: Mr. Watson — Come here — I want to see you («Мистер Ватсон, зайдите, я хочу вас видеть» — англ.). Чтобы позвонить в соседнюю комнату своему помощнику, Беллу не пришлось набирать номер — в мире на тот момент было только два телефонных аппарата.

03
Прошло несколько лет. Абонентов стало много. Аппаратов — тоже. Появились городские телефонные сети, каждому аппарату присвоили номер. Можно было позвонить на другой аппарат, назвав требуемый номер телефонистке.
04
В 1910 году в США, наиболее телефонизированной по тем временам стране, было более семи миллионов абонентов. В России — 155 тысяч. Обычный телефонный номер того времени был четырехзначным, в крупных городах — пятизначным. Чтобы позвонить за пределы городской сети, абоненту требовалось назвать телефонистке город и номер. Разговор заказывали и ждали.
05
В десятых годах XX века автоматические телефонные станции (АТС) постепенно стали вытеснять «барышень», которые соединяли абонентов вручную. К началу Первой мировой войны в США было более ста АТС, в Германии — семь, в Великобритании — две. В Москве первая такая станция появилась только в 1924 году в Кремле. Городская АТС заработала в 1930 году.
06
У них
Американцы, раньше всех столкнувшиеся с семизначными номерами, решили проблему запоминания (а тогда казалось, что семизначные номера помнить сложно) при помощи мнемонических правил — первые три цифры заменялись буквами, с которых начиналось какое-нибудь слово. По техническим соображениям в Америке на единицу не начинался ни один номер. По историческим соображениям ноль всегда использовался для вызова телефонистки. Таким образом, любой американский номер мог начинаться на любую цифру, кроме 1 и 0.
07
Мнемонические правила до середины 1960-х использовались в Лондоне и Париже. Американцы сначала использовали схему ABC-4567 (три буквы — четыре цифры). Так как запас новых слов, начинающихся с нужных трех букв, подходил к концу, в 1930 году Нью-Йорк, а в 1947-1948 годах и остальные города были переведены на схему AB3-4567.
08
Номера писались (и произносились) так:

У нас
Все, что было связано с телефоном (от аппаратов до станций), приходило в Россию с Запада. Международное телефонное общество Белла из Нью-Йорка в 1881 году заключило с российским правительством контракт на устройство и эксплуатацию телефонных сетей в Санкт-Петербурге, Москве, Варшаве, Одессе, Риге и Лодзи сроком на двадцать лет.
13
В России компания «Л. М. Эриксон и Ко» открыла свою первую станцию в 1893 году — в Киеве. В конце XIX века бывший владелец мастерской по ремонту телеграфных аппаратов Ларс Магнус Эриксон имел в России самый большой рынок сбыта и хотел даже переехать в Петербург. Сегодня компания «Эриксон» в своем годовом отчете описывает это так: «Уже в конце 1890-х Эриксон вел дела по всему миру, включая такие страны, как Китай, Россия и Мексика».
14
В 1900 году Эриксон построил свою первую зарубежную фабрику — в Санкт-Петербурге. В 1927 году она была переименована в «Красную зарю» и начала выпускать первые советские телефонные аппараты.
15
В Милютинском переулке в Москве находилась крупнейшая в Европе телефонная станция, которой владело Русско-датско-шведское акционерное общество (здание до сих пор используется в качестве телефонного узла). В 1917 году революционно настроенные массы в течение пяти дней осаждали засевших в здании юнкеров. Через пять дней ни одного юнкера не осталось, а из шестидесяти тысяч номеров работало около десяти тысяч. В 1920 году Совнарком распорядился отобрать у частных лиц все телефонные установки — номеров не хватало.
16
Хозяйке на заметку
Автоматический набор номера производился с телефонного аппарата, снабженного наборным диском. Предыдущие модели телефонов были с прямым выходом на телефонистку или с индуктором (той самой ручкой для звонков в Смольный), который также соединял с телефонисткой.
Телефоны с дисковым набором были редкостью и устанавливались только у важных лиц (двести номеров в Кремле и двадцать — в научно-техническом отделе ВСНХ). Такие аппараты называли вертушками. Сегодня это слово осталось в языке как обозначение прямого правительственного телефона в кабинете у большого начальника, хотя в современных «вертушках» номеронабиратель либо кнопочный, либо его нет вовсе.
17
Последнее, что могло волновать СССР в двадцатые годы, — создание системы мнемонических правил для запоминания телефонных номеров. В то время не были редкостью номера типа А-23-45 (буква — четыре цифры). Позже появились АТС и с двухбуквенными индексами, но поскольку каждая буква проговаривалась отдельно, это создавало только сложности при запоминании. Буквы рядом с цифрами в СССР использовались до 1968 года.

Как звонили
У первых телефонов номеронабирателя не было. В книге «Список абонентов Московской телефонной сети» за 1916 год первый пункт правил пользования телефонными аппаратами гласит: «Центральная станция вызывается простым снятием микротелефона с рычага. Дежурная на станции должна ответить, сообщая свой нумер. Затем абонент ясно и отчетливо сообщает нумер, с которым требуется соединение».
21
На первых дисковых аппаратах были только цифры. В 1920-е рядом с цифрами появились буквы.
22
В США на телефонном диске рядом с каждой цифрой (кроме единицы и нуля) находилось по три буквы алфавита. Буквы Q и Z не использовались из-за схожести с 0 и 2.
23
Англичане размещали букву O на нуле — все равно выглядят одинаково.
24
Шведы и немцы использовали по одной букве рядом с цифрой: A, B, C, D, E, F, G, H, J, K, занимая все десять цифр. Буква I не использовалась, так как ее легко спутать с единицей.
25
В СССР на телефоне рядом с цифрами тоже было десять букв: А, Б, В, Г, Д, Е, Ж, И, К, Л. Буква З не использовалась, потому что похожа на тройку.
26
Как звонят
Сегодня в России не производят телефонов с русскими буквами. Многие европейские телефоны выпускаются вообще без букв. Все американские телефоны рядом с цифрами содержат и буквы.
27
Все без исключения современные мобильные телефоны содержат полный латинский алфавит (а многие модели — дополнительный алфавит той страны, где они продаются). Тут возникает проблема с двумя способами использования букв. Первая модель — американская. Если водитель едет по дороге и видит на большом грузовике надпись How am I driving? Call 1-800-EAT-SHIT, это значит, что ему предлагают позвонить по телефону 1-800-328-7448.
28
Но при наборе СМС-сообщения буквы работают в другом режиме — недостаточно один раз тыкнуть кнопку, на которой изображена буква, нужно нажать несколько раз.
29
Система набора по буквам хорошо знакома в США, так как запомнить слово проще, чем последовательность цифр, хотя набирать потом жутко неудобно. Европейцы, знакомые с СМС, вообще не могут понять, как работает американская система.
30
В России пока только одна компания рискнула использовать подобный мнемонический прием для рекламы своего телефона — это проект «Мегафон», рекламирующий в Москве номер 500-ALLO (500-25-56). Об успехе подобного хода автору ничего не известно.
32
Лирическое отступление
После изобретения тонового набора в 1961 году порядок расположения цифр на кнопочном телефоне обсуждался инженерами компании «Белл». Рассматривалось несколько вариантов, среди которых — расположение кнопок по кругу, как на дисковых аппаратах. Думали, что людям будет тяжело вот так — раз! — и перейти на совершенно новую систему.
Однако исследования показали, что люди быстро привыкают к любому упорядоченному расположению клавиш. Поэтому было решено разместить кнопки тремя рядами по три цифры в привычной последовательности, то есть чтобы ноль шел после девятки, как на дисковом номеронабирателе.
Для счетной машины логичным является расположение нуля перед единицей, поэтому порядок кнопок на калькуляторе и на мобильном телефоне различается.
33
Как правильно писать телефонный номер
В Европе телефонные номера всегда отделялись блоками по две цифры.
34
Во Франции и в Великом Герцогстве Люксембург используют в качестве разделителя точки или пробелы (восьмизначные номера с кодом города):
12.34.56.78.90
12 34 56 78 90
0 800 12 34 56
35
В Германии используют пробелы (реже — дефисы):
123 45 67
123-45-67
00 49 (12 34) 12 34 56
(0 12 34) 1 23
36
В Болгарии всегда записывают номер тремя группами по две цифры:
12-34-56
37
Особняком стоят Италия и Голландия, где очень часто можно встретить номера телефонов без каких-либо разделителей: 12 1234567, 020-1234567 — вопиющее надругательство над человеком, пытающимся такой номер не то что запомнить, а всего лишь прочесть. Особенно не хватает разделительного знака в записной книжке мобильного телефона — с ходу разобрать десять слипшихся цифр невозможно.
38
В Великобритании (у которой в плане технических стандартов очень много общего с США) пишут номера двумя группами цифр после кода:
020 1234 1234
+44 20 1234 1234
01234 123456 (кроме Лондона)
0800 123456 (бесплатные номера)
39
Тут уместно напомнить, что в английском языке не принято большие числительные читать одним словом. Даже год при произношении разбивается на два отдельных числа: 1998 по-английски читается как «девятнадцать девяносто восемь», а не «одна тысяча девятьсот девяносто восемь». Иногда числа произносят по одной цифре.
40
На современный американский формат записи повлияли раннее развитие телефонизации, проблема появления длинных номеров и мнемонические правила.
41
В дореволюционной России (и в СССР) все телефонные номера записывались согласно правилу: дефисом или пробелом отделяются пары цифр справа налево. Если в начале остались три цифры, разрешается записать их слитно.
42
Пункт 3 правил, опубликованных в «Списке абонентов Московской телефонной сети» за 1916 год, гласит:
43
«Нумера свыше сотни произносятся так: напр. 1.23 — один двадцать три, 9.72 — девять семьдесят два, 70.09 — семьдесят нуль девять. Нумера свыше 10.000 — произносятся отдельно каждая цифра сотни, например 1.20.48 — один двадцать сорок восемь, 2.08.35 — два нуль восемь тридцать пять, 3.35.29 — три тридцать пять двадцать девять, 4.49.52 — четыре сорок девять пятьдесят два, 5.15.86 — пять пятнадцать восемьдесят шесть и т. д., а не сто двадцать сорок восемь, двести восемь тридцать пять и т. д.»
44
Эти правила хорошо знают и военные связисты — при произношении двузначных чисел вероятность ошибки принимающей (слушающей) стороны снижается.
45
Формат записи телефонного номера для России, стран СНГ и Балтии такой: 123-45-67. Многие бывшие советские республики переняли американский формат записи (123-4567), совершенно не учитывая культурных, исторических и семантических значений такого формата.
46
В телефонных справочниках дефисы заменялись на пробелы (для экономии времени наборщиков):

48
1960 год. «Список абонентов Московской городской телефонной сети. Квартирные телефоны» (из коллекции автора) |
49
1975 год. «Список абонентов Московской городской телефонной сети. Телефоны организаций, учреждений и предприятий» (из коллекции автора) |
50
В СССР слова не прижились — из первых десяти букв много слов не напридумаешь (а все 33 буквы алфавита расположить на диске в то время не представлялось разумным). В сочетании с очень сложными числительными формат записи группами по два знака был единственно удобным.
51
Кроме отдельных случаев с удачным сочетанием цифр (типа 222-3-222) сегодня в России номера телефонов нужно писать следующим образом:
52
Обычные городские номера
123-45-67
12-34-56
1-23-45
12-34
Стоит помнить, что в телефонных номерах дефисы можно безболезненно заменять на пробелы

Как правильно писать телефонные номера
Часто приходится слышать всякие глупости про телефонные номера. Разберемся, как их правильно писать.
Обычно телефонная надпись состоит из двух частей: подписи и самого номера. Например:
Сначала разберемся со словом.
Подпись
А нужно ли вообще
как-то
подписывать номер, ведь и так понятно, что это номер телефона?
Нет, не понятно.
Это может быть факс, номер аськи, кредитки или бог знает чего еще. У Стива Круга целая книга называется: «Не заставляйте меня думать». Так вот, не заставляйте меня думать. Всего три буквы избавят читателя от лишних вопросов.
Как сокращать: т., тел.?
Общепринято сокращение тел. При минималистическом дизайне допустимо написать т. Часто отлично смотрится слово телефон целиком.
Можно сразу указывать тип телефона: моб., м., факс.
По правилам русского языка после сокращения обязательно нужно ставить точку. После самого слова — двоеточие, после двоеточия — пробел.
Возможно также использование иконок, но часто это невозможно по техническим причинам или неуместно, да и выглядит это, как правило, плохо.
Номер
Телефонные номера следует различать не только по типу (городской, мобильный), но и по назначению (для местных звонков, междугородних, международных).
Телефонный номер всегда состоит из трех частей: префикс страны, код города, сам номер.
Сам номер
По правилам русского языка сам номер нужно писать через дефисы, разбивая цифры таким образом:
123-45-6712-34-561-23-4512-34
Исключение может быть сделано только для «красивых номеров»:
23-777-19
333-555-1
Код города
Код пишется в скобках перед телефоном, не разбиваясь дефисом, но обязательно с пробелом между кодом и номером:
(12345) 1-23-45
Код города необходим, если мы предполагаем, что будут звонить из других городов.
Префикс страны
Если предполагается, что по телефону могут звонить люди из другой страны, тогда надо добавить код страны со знаком выхода на международную линию (+7).
При этом код не будет писаться в скобках (т.к. его нельзя опустить).
Правильно:
+7 123
123-45-67
Мобильные телефоны надо писать так же, как и телефон для международной записи:
+7 916 123-45-67
Никаких скобок, так как из телефона нельзя ни при каких обстоятельствах выкинуть часть.
Таким образом, дизайнер должен понять, кто чаще всего будет звонить по телефону и в зависимости от этого определиться с форматом.
Несколько телефонов
Если телефонов несколько, то не надо каждый раз повторять префикс страны и код города:
(495) 123-45-67, 987-65-43, 123-45-67
Факс
В факсе обязательно писать код города.
Для большинства самой уместной записью является:
Тел.: (123) 123-45-67
Про историю записи телефонных номеров можно почитать у Артемия Лебедева в Ководстве.
