  1. For 'Area served' we list the rate center. In the North American Numbering Plan a rate center is a geographic area used to determine local calling boundaries for billing purposes. Its name is generally a locality, often not the only one served by an NPA-NXX combination.
  2. A single provider refers to the original company controlling a whole NPA-NXX block (10,000 phone numbers). With Number Pooling, NPA-NXX blocks can be split into ten 1,000 phone number blocks and handed over to other service providers (available in the USA and Puerto Rico).
  3. Assignment date. N/A: unavailable date or central office code assigned before 2001.
  4. NXX prefixes last updated: December 15, 2025
