List of telephone country codes

Telephone country codes are telephone number prefixes for reaching subscribers in foreign countries or areas by international direct dialing (IDD). Country codes are defined by the International Telecommunication Union (ITU) in ITU-T standards E.123 and E.164 and constitute the international telephone numbering plan of the public switched telephone network (PSTN) and other networks.

Overview

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

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 (x). When three-digit codes share a common leading pair, the shared prefix is marked by an arrow, () pointing down and left to the three-digit codes. 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 (**).
