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 listed 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 sources 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 for/of/by the Internet community.

See also the listing by state/country and the NANPA data. There are also several other listings on the web.

"split" refers to a service area served by one area code being subdivided into two or more areas, with the original area code serving one of the subdivisions and new areacode(s) serving the other(s).

"overlay" refers to a service area being served by two or more area codes simultaneously. usually i write "X overlaid on Y" to mean that X is a new areacode that will service an area that previously was serviced solely by Y.

the advantage of a split is that for intra-service area dialing, only 7 digits are required, but some existing users will be forced to change their web site, stationery, business cards, etc. in contrast, an overlay only affects new customers, so is less of a burden; however, neighbors may have to dial 11 digits to call each other.

The split/overlay information is not exhaustive. Older dates are removed.
