Area Code Listing, by Number

The cities listed with each area code are the major cities for that area code; this originated as the city in which the switch computer for that area code is located, but is no longer the case. The cities list are not intended to be exhaustive.

This list is updated only when an Internet user informs me of a (pending) change. There are no special data source from which this is generated -- just the cooperation of the Net. I do not have anything to do with phone companies etc; I do research in computer security, and this is just a random service to the Internet community.

See also the listing by state/country and the NANPA data. There's also a listing at geocities and areacode-info.com
