About the North American Numbering Plan

The NANP is a unified telephone numbering plan used by the United States and its unincorporated territories, Canada, Bermuda and most Caribbean islands. All telephone numbers within the NANP have the same dialing format: xxx yyy yyyy (3 digit area code + 7 digit local number).

NANP members

The main two countries using NANP area codes are the United States and Canada. Other countries, territories and municipalities using this numbering system are: American Samoa, Anguilla, Antigua & Barbuda, the Bahamas, Barbados, Bermuda, the British Virgin Islands, Cayman Islands, Dominica, the Dominican Republic, Grenada, Guam, Jamaica, Montserrat, Northern Mariana Islands, Puerto Rico, Sint Maarten, St. Kitts & Nevis, St. Lucia, St. Vincent & the Grenadines, Trinidad & Tobago, Turks & Caicos, US Virgin Islands.

Country code 1 (one) is shared by all NANP members.

Dialing between 2 NANP countries

Since this is a unified numbering plan, calls between NANP member countries have the same dialing format: 1 xxx yyy yyyy. The initial 1 (one) here is not a country code, but a trunk code used to dial long distance calls. There is no need to add + or 011, which is the IDD code used by NANP members to dial internationally. However, calls between different countries are still considered international calls and charged accordingly.

For example, to dial the Bahamas from the USA or from any other NANP location you would use the following: 1 242 yyy yyyy, while a call from California to New York City looks very similar: 1 212 yyy yyyy (242 and 212 are area codes serving the Bahamas and New York City respectively).

Dialing to any NANP country from the rest of the world

All members of the North American Numbering Plan use country code 1. To dial or text to any of these countries/territories use: +1 xxx yyy yyyy. The initial plus sign can be either dialed (with most wireless devices) or replaced with your country's IDD (International Direct Dialing) code.
