NANP covers 25 regions in Canada, the United States, parts of the Caribbean Sea and some islands in Pacific and Atlantic oceans. 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.

  • NPA = Numbering plan area code
  • NXX = Central office(exchange) code
  • XXXX = Local number(subscriber number)
