List of international dialling codes :-

Country dial-in codes or country calling codes are telephone number prefixes used to reach telephone users in the networks of the International Telecommunication Union’s member nations or regions (ITU). The ITU-T established the codes in standards E.123 and E.164. International direct dialling (IDD) is enabled by the prefixes, which are also known as international subscriber dialling (ISD).

Country codes are part of the international phone numbering system and are only needed when dialling a phone number from one country to another. Dial the country code before dialling the national phone number. International phone numbers are traditionally preceded by a plus sign (+), which also informs the subscriber that the number is international.

The ISO 3166-1 alpha-2 country codes are used to identify the countries.When three-digit codes begin with “+jk,” the two-digit code +jk is unassignable, as indicated by the term “unass.” The m-dash (—) denotes assignable but unassigned codes.
