need zip code to state map or something else

[BitShift]

I need a way of determining what state a given zip code falls in. Anyone know if one of the map apis like google or yahoo will give this? Or maybe the us postal service, they have an api to use also.

help?

on what platform do you need to do this?
for example i remember reading about a way to do this in the google maps api using javascript but that won't help if you are doing something server side...

Probably easiest to just download a list of Zip codes & states and convert to a DB on your server. Then it's an easy query to get your answers.
