List of ISO 639-2 codes

This article should specify the language of its non-English content, using {{lang}}, {{transliteration}} for transliterated languages, and {{IPA}} for phonetic transcriptions, with an appropriate ISO 639 code. Wikipedia's multilingual support templates may also be used. See why. (January 2024)

ISO 639 is a set of international standards that lists short codes for language names. The following is a complete list of three-letter codes defined in part two (ISO 639-2) of the standard,^[1] including the corresponding two-letter (ISO 639-1) codes where they exist.

Where two ISO 639-2 codes are given in the table, the one with the asterisk is the bibliographic code (B code) and the other is the terminological code (T code).

Entries in the Scope column distinguish:

• individual language
• collections of languages connected, for example genetically or by region
• macrolanguages.

The Type column distinguishes:

• living (natural languages in current use)
• ancient languages (extinct since ancient times);
• historical languages (distinct from their modern form);
• extinct languages in recent times;
• constructed languages.

The standard includes some codes for special situations:^[1]

• mis, for "uncoded languages";
• mul, for "multiple languages";
• qaa–qtz, a range reserved for local use;
• und, for "undetermined";
• zxx, for "no linguistic content; not applicable";
