# List of ISO 639-2 codes

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, including the corresponding two-letter (ISO 639-1) codes where they exist.

## Codes

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:
* 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";
