United States ZIP Code Database is a list of U.S. Zip codes for
quick reference. I downloaded the file they provided us and it only contained a
bit of information on zip code format and a few zip codes.
Undeterred I went to their website and tried the 'free demo' which is basically
a lookup tool from which you can search for a zip code by typing in a city or a
city by typing in its zip code. It does go a bit further and also allow you to
search for a zip code by typing in an area code from a phone number or typing in
a county name.
I don't really see a use for this type of software unless you do a lot of zip
code look ups for a business or something but the online demo at least worked
well enough. Its hard for me to rate their software based on a demo but from
what I've seen if its like the website based demo it does work and that's really
about all I can say for it.
If you need this, then by all means test it out online if not well, then I guess
you'll just have to live without knowing the zip code for Clinton New York and
other exotic places!
