- Country code
Country codes are short alphabetic or numeric geographical codes (geocodes) developed to represent countries and dependent areas, for use in data processing and communications. Several different systems have been developed to do this. The best known of these is ISO 3166-1. The term country code frequently refers to international dialing codes, the E.164 country calling codes.
This standard defines for most of the countries and dependent areas in the world:
- a two letter (ISO 3166-1 alpha-2)
- a three-letter (ISO 3166-1 alpha-3), and
- a three-digit numeric (ISO 3166-1 numeric) code.
The two-letter codes are used as the basis for some other codes or applications, for example,
- for ISO 4217 currency codes and
- with deviations, for country code top-level domain names (ccTLDs) on the Internet: list of Internet TLDs.
For more applications see ISO 3166-1 alpha-2.
