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.
More than one region subtag: de
Extlang subtag alt not found.
Subtags incorrectly ordered. Current order:
languagede - region419 - regionde - extlangalt
Expected order:
language - extlang - region
Check that the region subtag 419 contributes information needed to distinguish this language tag from another one, otherwise leave it out. For example, en-GB can be useful for spell-checking, but the region subtag in ja-JP is unlikely to be useful unless you are intentionally contrasting it with Japanese spoken in other parts of the world.
Check that the region subtag DE contributes information needed to distinguish this language tag from another one, otherwise leave it out. For example, en-GB can be useful for spell-checking, but the region subtag in ja-JP is unlikely to be useful unless you are intentionally contrasting it with Japanese spoken in other parts of the world.
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.
