The North American Numbering Plan (NANP) is the system used throughout North America to designate telephone area codes. It was introduced in 1947 and serves more than 25 countries and the Caribbean Islands. The NANP is managed by the North American Numbering Plan Administration which is part of the US Federal Communications Commission. Every area code is three digits long and is composed of a three-digit code beginning with a number between two and nine, followed by two digits that range from zero to nine. Each area code is unique to a particular geographical area and allows matching a telephone number to its geographic location.
