About the North American Numbering Plan:

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

Countries part of the NANP:

The main two countries using North American area codes are the US and Canada. Other countries/territories 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.

Dialing between 2 NANP countries:

Technically, calling from a country using the North American Numbering Plan to another is just like placing a US state to state phone call (1 + xxx + xxx xxxx). In other words there is no need to dial the 011 IDD code required for all other overseas calls. However, as far as calling rates are concerned - you will incur international charges when dialing out of your country whether that particular country uses the NANP or not.

Example: say you want to place a call to Jamaica from the USA. The area code for Jamaica is 876 so you would simply dial: 1 876 xxx xxxx.
