Area Codes In The United States
The North American Numbering Plan (NANP) is an integrated telephone numbering plan administered by Neustar (formerly Lockheed Martin IMS) which encompasses 24 countries and territories, including the United States and its territories, Canada, Bermuda, and 17 nations of the Caribbean. The term is also used, by metonymy, to refer to the geographic area in which that plan has been implemented.
The NANP is a standardized system of numbering plan areas (NPA), which have evolved over time into a system of three-digit area codes and seven-digit telephone numbers. Through this plan, telephone calls can be directed to particular regions of the larger NANP public switched telephone network (PSTN), where they are further routed by the local networks.
