Don't forget that number portability significantly muddied the waters, and VoIP has created an environment where there's no longer any need for a physical relationship. For example, ipKall offers Washington state phone numbers for free. Probably unusual to find your average end user having such a number, but some people on this list will. Number portability probably means that you either need a bit of fuzzy logic to determine if the ZIP and the NPA-NXX are in the same region, or you need to be clever about the implementation and how you handle negative matches. ...
