How I can make Apple reach a formal request to include Andorra in the list of international codes?

Apple recognizes Andorra Telecom (Mobiland) as an authorized operator.

However it does not include the international dialing code of Andorra (+376) in the list of telephone prefixes countries.

This prevents verification services, such as two-step and two-factor authentication.

Thanks.
