Country code

This standard defines codes for most countries and dependent territories of the world:

• two-letter (ISO 3166-1 alpha-2),
• three-letter (ISO 3166-1 alpha-3) and
• three-digit digital (ISO 3166-1 numeric) code.

Two-letter codes are used as the basis for some other codes, for example:

• for currency codes according to ISO 4217 ,
• with little discrepancies for top-level country domain names (ccTLDs) on the Internet.

For other applications see ISO 3166-1 .

The standard GOST 7.67 "Codes of country names" establishes alphanumeric designations of country names in coded form, common for various information processing systems, its storage and exchange, as well as unified rules for the formation of codes. The standard is a translation of ISO 3166 -88, Codes for the Submission of Country Names.

Currently, the standard GOST 7.67-2003, entered into force on January 1, 2005, is in force.
