ISO 639-2

ISO 639 is a set of international standards that lists short codes for language names. First there was ISO 639-1. To list more languages, ISO 639-2 was made. Later versions include ISO 639-3 and ISO 639-5.

Each language has a 3 letter code. The list below shows all the codes in ISO 639-2.

The following is a complete list of three-letter ISO 639-2 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 Notes column show:

• ancient languages (extinct since ancient times);
• collections of languages;
• constructed languages;
• languages extinct in recent times;
• historical languages (distinct from their modern form);
• macrolanguages.
