The Part 1 code [bh] for Bihari languages has been deprecated per ballot of the Joint Advisory Committee for ISO 639. There is still a part 2 code [bih] which can be used for this language group. The code tables have been updated to reflect this change.

The Registration Authority for ISO 639-3 is accepting Change Requests for 2021 until August 31, 2021. Please submit all relevant forms and additional supporting documentation by that date for consideration this year.
