The North American Numbering Plan (NANP) is a standardized system for the numbering of telephone lines in many parts of the world. The NANP is administered by the North American Numbering Plan Administration (NANPA), a unit of Neustar, a communications services provider. The NANP is used by phone companies to assign telephone numbers in the United States, Canada, and 20 Caribbean countries. It divides the region into geographic areas and assigns a single three-digit area code to each area. The 660 area code is part of this system, and it encompasses the northeastern portion of Missouri.
