'''NANP''' stands for '''North American Numbering Plan'''. It is 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, Anguilla, Antigua & Barbuda, Bermuda, the Bahamas, Barbados, the British Virgin Islands, Canada, the Cayman Islands, Dominica, the Dominican Republic, Grenada, Jamaica, Montserrat, St. Kitts and Nevis, St. Vincent and the Grenadines, St. Lucia, Turks & Caicos and Trinidad and Tobago. NANP aims to reduce the complexity of dialing long distance international calls, making the direct dialing easy for long distance calls within the NANP network. NANP developed a three digit code area code and a seven digit local telephone number system. Through this system, calls can be directly switched to the particular area of the 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>
