This is the home page for Part 3 of the ISO 639 family of standards, Codes for the representation of names of languages. ISO 639-3 attempts to provide as complete an enumeration of languages as possible, including living, extinct, ancient, and constructed languages, whether major or minor, written or unwritten.

- 3 simple retirements, one is a correction to a change made last year;
- 2 merged retirements;
- 2 split languages, resulting in 4 new language code elements (a net gain of 2).
- Completely new languages: 7 newly created languages not previously associated with another language in the code set: 5 living languages and 2 extinct languages.

ISO 639-3 is a code that aims to define three-letter identifiers for all known human languages. At the core of ISO 639-3 are the individual languages already accounted for in ISO 639-2. The large number of living languages in the initial inventory of ISO 639-3 beyond those already included in ISO 639-2 was derived primarily from Ethnologue (15th edition). Additional extinct, ancient, historic, and constructed languages have been obtained from Linguist List.
SIL International has been designated as the ISO 639-3/RA for the purpose of processing requests for alpha-3 language codes comprising the International Standard, Codes for the representation of names of languages - Part 3: Alpha-3 code for comprehensive coverage of languages. The ISO 639-3/RA receives and reviews applications for requesting new language codes and for the change of existing ones according to criteria indicated in the standard. It maintains an accurate list of information associated with registered language codes which can be viewed on or downloaded from this website, and processes updates of registered language codes. Notification of pending and adopted updates are also distributed on a regular basis to subscribers and other parties.
