The North American Numbering Plan (NANP) is a telephone numbering plan that encompasses twenty-five distinct regions in twenty countries primarily in North America, including the Caribbean.
The NANP was originally devised in the 1940s by AT&T for the Bell System and independent telephone operators in North America to unify the diverse local numbering plans that had been established in the preceding decades.
The NANP divides the territories of its members into numbering plan areas (NPAs) which are encoded numerically with a three-digit telephone number prefix, commonly called the area code. The telephone number consists of a three-digit central office code and a four-digit station number. The combination of an area code and the telephone number serves as a destination routing address in the public switched telephone network.
Twenty-four countries and territories share the North American Numbering Plan (NANP), with a single country code. The formatting convention for phone numbers is NPA-NXX-XXXX, where NPA is the three digit area code and NXX-XXXX is the seven digit subscriber number.
Originally, local calls within an area code could be placed by dialing NXX-XXXX, omitting the area code, known as 7-digit dialing. Only calling a destination in a different area code required dialing the destination area code, known as ten-digit dialing, but due to the need for additional telephone numbers in many regions, seven digit dialing is becoming rare in the United States.
