Standardization

We use the ISO 639-3 standard to classify languages. This standard is extremely extensive and meant to cover all known languages. In the case of Swahili for example, the ISO 639-1 code is sw and the ISO 639-2 code is swa. The ISO 639-3 standard allows for a more detailed classification of Swahili, using swc for Congo Swahili and swh for Coastal Swahili.

​
Languages not covered by ISO 639-3

We do not currently cover any languages that are not covered by ISO 639-3. Should this change in the future, we will maintain existing languages codes so as not to break existing API integrations.
