Language codes

Wikimedia projects use language codes to identify language specific editions of a Wikimedia project. The codes are often used as a subdomain, e.g. for the Wikipedia editions it is a subdomain below wikipedia.org. Interlanguage links in the English Wikipedia are sorted by that code.

The codes mostly correspond to the language codes defined by ISO 639-1 and ISO 639-3, and the decision of which language code to use is mostly in accordance with the IETF language tag policy.

One code is not a language code ('be-x-old') but refers to a specific orthography.

Codes that do not agree with the ISO 639 meaning or are deprecated

Several codes are used for project editions where the ISO 639 meaning is different from the content contained in the project.^[1]

This makes the codes partially "not useful".^[2]
