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.
Assignment date. N/A - mostly central office codes assigned before 2001.
NXX prefixes last updated: August 27, 2024
