ConLang Code Registry
The ConLang Code Registry (CLCR) is a project led by Rebecca Bettencourt to assign ISO-639-3 codes out of the "reserved for local use" area (qaa-qtz) to constructed languages.
Constructed Languages with ISO-639-3 Codes
The following constructed languages already have official ISO-639-3 codes and will therefore not be included in the CLCR.

|---|---|---|---|---|---|

bzt | Brithenig | jbo | Lojban | sjn | Sindarin |
dws | Dutton World Speedwords | ldn | Láadan | tlh | Klingon |
