About NANPA

About The North American Numbering Plan Administrator (NANPA)

NANPA holds overall responsibility for the neutral administration of NANP numbering resources, subject to directives from regulatory authorities in the countries that share the NANP. NANPA's responsibilities include assignment of NANP resources, and, in the U.S. and its territories, coordination of area code relief planning and collection of utilization and forecast data.

NANPA is not a policy-making entity. In making assignment decisions, NANPA follows regulatory directives and industry-developed guidelines. NANPA's responsibilities are defined in Federal Communication Commission (FCC) rules and in comprehensive technical requirements drafted by the telecommunications industry and approved by the FCC.

Since 1997, the FCC has selected the company that serves as the NANPA through a competitive bidding process. In 1997, Neustar (then Lockheed Martin IMS) was selected to serve for a five-year term as NANPA. Neustar was again selected in July 2003 to serve as the NANPA. In June 2012, the NANPA function was again competitively bid by the FCC and Neustar was chosen to serve another five-year term.

In 2018, the NANPA function was competitively bid by the FCC and Somos was chosen to act as the NANPA for a one-year term.

Regulatory authorities in various NANP countries have named national administrators to oversee the numbering resources assigned by NANPA for use within their country. NANPA is the national administrator for the U.S. and its territories. COMsolve Inc. serves as the Canadian Numbering Administrator. In other participating countries, regulatory authorities either serve as the national administrator or delegate the responsibility to the dominant carrier. NANPA, in its overall coordinating role, consults with and provides assistance to regulatory authorities and national administrators to ensure that numbering resources are used in the best interests of all participants in the North American Numbering Plan.
