Maps ZIPcode (US Postal code) to city, county, state and latitude-longitude.
Data Records: 42,741
Notes [from original author]: This database is a few years old but still works well for me. I originally created it to auto-populate city, county, state information based on zip code. Almost all ZIP codes have lon/lat values associated with them but some ZIP codes do not. Most of those are military zip codes but there are some others. If you find an entry that doesn’t have a long/lat and you happen to know the correct info please let me know. Please also be sure to report any errors or suspected errors with the data and I’ll check into it.
