The NPA is the Numbering Plan Area (area code) and NXX is the central office code.
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.
The assignment date. If no date is shown the exchange code was assigned before 2001.
