List of country calling codes

Add article description

Country calling codes, country dial-in codes, international subscriber dialing (ISD) codes, or most commonly, telephone country codes are telephone number prefixes for reaching telephone subscribers in foreign countries or areas via international telecommunication networks. Country codes are defined by the International Telecommunication Union (ITU) in ITU-T standards E.123 and E.164. The prefixes enable international direct dialing (IDD).

Worldwide distribution of country calling codes. Regions are coloured by first digit.

Country codes constitute the international telephone numbering plan. They are used only when dialing a telephone number in a country or world region other than the caller's. Country codes are dialed before the national telephone number, but require at least one additional prefix, the international call prefix which is an exit code from the national numbering plan to the international one. In most countries, this prefix is 00, an ITU recommendation; it is 011 in the countries of the North American Numbering Plan while a minority of countries use other prefixes.

Overview

The nine world zones are generally organized geographically, with exceptions for political and historical alignment.

Ordered by world zone

World zones are organized principally, but only approximately, by geographic location. Exceptions exist for political and historical alignments.

Zone 1: North American Numbering Plan (NANP)

See also: List of North American Numbering Plan area codes

NANP members are assigned three-digit numbering plan area (NPA) codes under the common country prefix 1, shown in the format 1 (NPA).

Zone 2: Mostly Africa

(but also Aruba, Faroe Islands, Greenland and British Indian Ocean Territory)

Zones 3–4: Europe

See also: Telephone numbers in Europe

Some of the larger countries were assigned two-digit codes to compensate for their usually longer domestic numbers. Small countries were assigned three-digit codes, which also has been the practice since the 1980s.

Zone 5: South and Central Americas

Zone 6: Southeast Asia and Oceania

Zone 7: Russia and neighboring regions

Formerly assigned to the Soviet Union until its dissolution in 1991.

Zone 8: East Asia, South Asia, and special services

Zone 9: West, Central, and South Asia, and part of Eastern Europe

Summary

This table lists in its first column the initial digits of the country code shared by each country in each row, which is arranged in columns for the last digit. When three-digit codes share a common leading pair, the two-digit code is unassigned, being ambiguous (denoted by "ambig."). Unassigned codes are denoted by a dash (—). Countries are identified by ISO 3166-1 alpha-2 country codes; codes for non-geographic services are denoted by two asterisks (**).
