Find the codes
City & county by ZIP.

City, ZIP and county — and why all three matter
A single US city can span dozens of ZIP codes, and ZIP codes don’t always respect county lines. For freight, the county can matter as much as the city: it can affect taxes, permits for oversize or hazmat loads, and which terminal serves a delivery.
Enter a city to list every ZIP it covers and the county for each. Add a state to narrow it down when a city name is shared across the country — there are a lot of Springfields. You can also paste a ZIP code to look up its city and county directly.
