City, State Lookup from Postal Code

Ruby

Does anyone know the easiest way to find a city and state based on a
supplied postal code?

Thanks for your help.

You could use Google’s or Yahoo’s geo-coding api for that.

I had to do that for a store website once, and I bought a giant text
file with every ZIP code for about $5. ZIP codes change from time to
time (and new ones are added), so you have to buy a new copy every
once in a while.

Or you could use the APIs Bill talked about, which is probably a more
robust solution, though a bit more complicated to implement.
