Telephone country codes are telephone number prefixes for reaching subscribers in foreign countries or areas by international direct dialing (IDD). Country codes are defined by the International Telecommunication Union (ITU) in ITU-T standards E.123 and E.164 and constitute the international telephone numbering plan of the public switched telephone network (PSTN) and other networks.
Overview
This table lists in its first column the initial digits of the country code shared by each country in each row, which is arranged in columns for the last digit (x). When three-digit codes share a common leading pair, the shared prefix is marked by an arrow, (<span style="background-color:#bebada"> â </span>) pointing down and left to the three-digit codes. Unassigned codes are denoted by a dash (<span style="background-color:#8dd3c7">âÂÂ</span>). Countries are identified by ISO 3166-1 alpha-2 country codes; codes for non-geographic services are denoted by two asterisks (<span style="background-color:#ffffb3">**</span>).
List by world numbering zones
<span class="anchor" id="Zone 1"></span> Zone 1: North American Numbering Plan (NANP)
North American Numbering Plan members are assigned three-digit numbering plan area (NPA) codes under the common country code 1, shown in the format 1 (NPA). Within an NPA, all telephone numbers have seven digits.

(but also Aruba, Faroe Islands, Greenland and British Indian Ocean Territory)
<span class="anchor" id="Zone 3"></span> <span class="anchor" id="Zone 4"></span> Zones 3 and 4: Mostly Europe
The larger countries were assigned two-digit codes starting in 1960. Subsequently, beginning in 1964, smaller countries were assigned three-digit codes, which also has been the practice since the 1980s.
