'''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>

==Code Plan==  

Earlier the codes were designed in the form of N-Y-X, in which N is a number between 2-9, Y is either 0 or 1 and X represents any number from 1-9 (if Y is 0) or any number between 2-9 (if Y is 1).  This restriction provides assistance to allocate some essential service with special codes, such as 0- Operator, 1- for signaling long distance calls, 00- long distance operator,                 011- international access code, 911- for emergency services such as fire, ambulance and police and so on. But after mid 1990’s and earlier 21st century, there had been rapid growth in telecommunication industry. This demand raised the necessity for allocation of more codes. But the restrictions on the code format limited the number of codes which can be allocated. This caused the North American Numbering Plan Administrator (NANPA) which acts as an administrating organization of NANP to expand the number range. The restriction on middle term ‘Y’ was lifted and the new area codes can use any number from 2 and 8 for the middle term of the three digit code. Thus the new area codes were allotted, the area code given for Alabama is 334 and Washington is 360 and so on. <ref name="link5">[http://www.squidoo.com/area_codes squidoo.com]</ref>
