ISO 639-1:2002 Codes for the representation of names of languages Part 1: Alpha-2 code is the first part of the ISO 639 series of international standards for language codes. Part 1 covers the registration of two-letter codes. There are 136 two-letter codes registered. The registered codes cover the world's major languages.

These codes are a useful international and formal shorthand for indicating languages. For example: English is represented by en Lithuanian is represented by lt Italian is represented by it French is represented by fr German is represented by de (from the endonym Deutsch) Japanese is represented by ja (even though its endonym is Nihongo) Portuguese is represented by pt Spanish is represented by es (from the endonym espaol) Catalan is represented by ca Swedish is represented by sv (from the endonym Svenska)

ISO 639 the original standard for language codes was approved in 1967. It was split into parts and in 2002 ISO 639-1 became the new revision of the original standard. The last code added was ht representing Haitian Creole on 2003-02-26. The use of the standard was encouraged by IETF language tags introduced in RFC 1766 in March 1995 and continued by RFC 3066 from January 2001 and RFC 4646 from September 2006. The current version is RFC 5646 from September 2009. Infoterm (International Information Center for Terminology) is the registration authority for ISO 639-1 codes.

New ISO 639-1 codes are not added if an ISO 639-2 code exists so systems that use ISO 639-1 and 639-2 codes with 639-1 codes preferred do not have to change existing codes.1

If an ISO 639-2 code that covers a group of languages is used it might be overridden for some specific languages by a new ISO 639-1 code.
