(Two-letter country-specific top-level-domain code suffixes are often different from these language-tag prefixes). ISO 639-1_sentence_7

ISO 639, the original standard for language codes, was approved in 1967. ISO 639-1_sentence_8

The last code added was ht, representing Haitian Creole on 2003-02-26. ISO 639-1_sentence_10

Infoterm (International Information Center for Terminology) is the registration authority for ISO 639-1 codes. ISO 639-1_sentence_13

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. ISO 639-1_sentence_14

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. ISO 639-1_sentence_15
