At one point, I had a listing of (nearly) all US zip codes, the cities and
states to which they belong, and the latitude and longitude for that zip. I
used that for a project in which I calculated the distance between two zips.
The problem with zip codes is that they don't have a 1:1 mapping. Larger
cities have multiple zip codes, sometimes two or more small cities may share
the same zip code, and there's even a loose correlation where the USPS sees
a zip code and while it technically doesn't belong to a particular city,
it's valid enough for delivery.
