Use of ISO-639 codes

The language codes defined in the several sections of ISO-639 are used for bibliographic purposes and, in computing and internet environments, as a key element of locale data. The codes also find use in various applications such as Wikipedia URLs for its different language editions. In computing, locale is a set of parameters that defines the users language, country and any special variant preferences that the user wants to see in their user interface. ...

Alpha-2 code space

"Alpha-2" codes (for codes composed of 2 letters of the basic Latin alphabet) are used in ISO 639-1. Thus, there are 26 × 26 = 676 distinct Alpha-2 codes. This is clearly insufficient to cover all languages, which led to the creation of ISO 639-2 and the use of Alpha-3 codes. Variants of the Latin alphabet are used by the writing systems of many languages throughout the world. ... ISO 639-1 is the first part of the ISO 639 international-standard language-code family. ... ISO 639-2 is the second part of the ISO 639 standard, which lists codes for the representation of the names of languages. ...


Alpha-3 code space

"Alpha-3" codes (for codes composed of 3 letters of the basic Latin alphabet) are used in ISO 639-2 and ISO 639-3 and will eventually be used in ISO 639-5. Mathematically, the upper limit for the number of languages and language collections that can be so represented is 26 × 26 × 26 = 17,576. Variants of the Latin alphabet are used by the writing systems of many languages throughout the world. ... ISO 639-2 is the second part of the ISO 639 standard, which lists codes for the representation of the names of languages. ... ISO 639-3 is in process of development as an international standard for language codes. ... ISO/DIS 639-5 Codes for the representation of names of languages – Part 5: Alpha-3 code for language families and groups, being developed by ISO/TC 37/SC 2. ...


The common use of Alpha-3 codes by three parts of ISO 639 requires some coordination within a larger system.


Part 2 defines four special codes mul, und, mis, zxx, a reserved range qaa-qtz (20 × 26 = 520 codes) and has 23 double entries (the B/T codes). This sums up to 520 + 23 + 4 = 547 codes that cannot be used in part 3 to represent languages or in part 5 to represent language families or groups. The remainder is 17,576 – 547 = 17,029.


There are somewhere around six or seven thousand languages on Earth today[1][2]. So those 17,029 codes are adequate to assign a unique code to each language, although some languages may end up with arbitrary codes that sound nothing like traditional name(s) of that language.


Alpha-4 code space

"Alpha-4" codes (for codes composed of 4 letters of the basic Latin alphabet) is proposed to be used in ISO 639-6. Mathematically, the upper limit for the number of languages and dialects that can be so represented is . Variants of the Latin alphabet are used by the writing systems of many languages throughout the world. ...
