Use
This service converts a country number to the unterminated 2 letter abbreviation specified in ISO3166-1. Conventionally, this is the country’s top level domain name.
Notes
The UK uses ‘uk’ in preference to its allocated ‘gb’ abbreviation.
If a module provides additional countries it should check this service – if the number matches one provided by the module it should claim this service.
