How to use Country Calling Codes

Looks up a country by calling code (+44), ISO region (GB) or English country name and returns the calling code, every region that shares it, national number lengths, trunk and international dialing prefixes, example numbers and the leading digits of mobile and fixed-line numbers where the numbering plan defines them. Derived from open libphonenumber metadata and CLDR country names; it describes numbering-plan rules, not who is assigned a number.
