ISO 639-2 language codes

This project was built out of the need to have a full set of all different ISO 639-2 language codes as well as the English and the native Full Name.

About the ISO 639-X

There're two subset of this ISO Norm.

  • ISO 639-1 (Alpha-2 code/1988)
  • ISO 639-2 (Alpha-3 code/1998)

Every language code present in the two-letter code set has a corresponding language code in the alpha-3 list, but not necessarily vice versa. ISO 639-2:1998 provides two sets of three-letter alphabetic codes for the representation of names of languages, one for terminology applications and the other for bibliographic applications. The code sets are the same except for twenty-five languages that have variant language codes because of the criteria used for formulating them.

The language codes were devised originally for use by libraries, information services, and publishers to indicate language in the exchange of information, especially in computerized systems.
