Area Code Frequently-Asked Questions

Who is in charge of area codes?

Area codes, known technically as NPAs (Numbering Plan Areas), are administered by the North American Numbering Plan Administrator ("NANPA"). The current NANPA is Lockheed Martin IMS. Lockheed Martin is responsible for forecasting the need for new area codes and for assisting state authorities in implementing them. The final details are decided by state authorities. In our home state of California, for example, the California Public Utilities Commission is responsible for working out the details, soliciting public comment, and setting forth the schedules and procedures for implementation.
