'''NANP''' stands for '''North American Numbering Plan'''. It a telephone numbering plan designed and used commonly by 19 different countries and territories in North America. These countries include the United States and its territories, Canada, Bermuda, Anguilla, Antigua & Barbuda, the Bahamas, Barbados, the British Virgin Islands, the Cayman Islands, Dominica, the Dominican Republic, Grenada, Jamaica, Montserrat, St. Kitts and Nevis, St. Lucia, St. Vincent and the Grenadines, Trinidad and Tobago, and Turks & Caicos. NANP aims to reduce the complexity of dialing long distance international calls and make it direct dialing of long distance calls easy within the NANP network. NANP over the period of time had developed a three digit code area code and a seven digit local telephone number system. Through this system the calls can be directly switched to the particular area of NANP- Public Switched Telephone Network (PSTN), from where they can be further transferred to the designation using the local networks. <ref>[http://www.nanpa.com/about_us/abt_nanp.html nanp.com]</ref><ref>[http://www.networkworld.com/details/644.html networkworld.com]</ref>
