Telephone Numbers In The United States
The North American Numbering Plan (NANP) is an integrated telephone numbering plan that encompasses 24 countries and territories primarily in North America and the Caribbean.
The NANP is a standardized system of numbering plan areas (NPA) using telephone numbers consisting of three-digit area code, a three-digit central office code, and a four-digit station number. 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. The NANP is administered by the North American Numbering Plan Administration (NANPA), a service operated by Neustar corporation. The international calling code for the NANP is 1. Not all North American countries participate in the NANP.

—Woodrow Wilson (1856–1924)
