Language Subtag Lookup

BCP 47 language tags are built from subtags in the IANA Subtag Registry. This tool helps you find or look up subtags and check for errors in language tags.

Read Choosing a Language Tag for step-by-step guidelines on creating language tags. This tool also provides information to guide your choices.

Check whether a hyphen-separated tag is valid and well-formed See note 4.

List all tags of the following type


Language Codes

Look up in the SIL Ethnologue. mg Malagasy

Note.    mg is a macrolanguage that encompasses the following more specific primary language subtags: bhr bjq bmm msh plt skg tdx txy xmv xmw. If it doesn't break legacy usage for your application, you should use one of these more specific language subtags instead. On the other hand, mg is often preferred by legacy applications rather than plt (Malagasy, Plateau).

This version has been updated to support the approximately 7800 new subtags, including extlang subtags, introduced in July 2009, and the tool now provides help in choosing subtags and a tag checker based on RFC 5646. Please report any bugs to me.
Currently supports the IANA Subtag registry of 2010-08-17. The tool currently reports subtags for 7,844 languages, 225 extlangs, 148 scripts, 297 regions, 50 variants, and 26 grandfathered subtags.
