Welcome to the Numbering Resources Page. The Commission’s numbering policies are designed to ensure the efficient and effective use of telephone numbers for the provision of telecommunications services. The Commission works closely with the North American Numbering Council, the Commission’s federal advisory committee on numbering issues, state commissions, and industry groups to achieve effective numbering resource management. The Commission has sought to optimize the use of numbering resources by: (1) minimizing negative impact on consumers of premature area code exhaust; (2) ensuring access to numbering resources for all service providers; (3) extending the life of the NANP; (4) imposing the least societal cost possible, and ensuring competitive neutrality; (5) minimizing incentives for carriers to carry excessively large inventories of numbers. Some of the measures used by the Commission include: area code relief; thousands-block number pooling; and local number portability.
