Frequently Asked Questions

Can one ZIP Code be in more than one county?

Yes. ZIP Codes follow mail delivery routes, not county lines, so many ZIP Code areas touch more than one county. Our ZIP Code lookup lists every county and its share of the area; for an exact answer, use a street address.

How accurate is "Use my location"?

Phones with GPS are usually accurate to within a few dozen feet. Laptops and desktops often estimate location from Wi-Fi or your internet connection, which can be off by a mile or more. We show the accuracy your browser reports and list every county within that range when you might be near a county line.

Why does my result say "parish," "borough," or "city"?

We use the Census Bureau's official names. Louisiana's county equivalents are parishes, Alaska has boroughs and census areas, and some cities (mostly in Virginia) are independent of any county. In Connecticut, Census Bureau data has used nine planning regions in place of the eight historical counties since 2022.

What is a FIPS code?

A FIPS code is a 5-digit number that identifies a county: the first two digits are the state and the last three are the county. Use the Copy button to copy your county name, state, and FIPS code together.

Why is my city in a different county than I expected?

Cities don't always sit inside one county. Some cities span several counties, and many addresses with a city's name in them are actually outside the city limits. The county result is based on the exact point, not the city name in the address.

Does this work outside the United States?

County, city, state, and ZIP Code lookups cover the 50 states, Washington, D.C., and Puerto Rico.

Where does the data come from, and how current is it?

Is this site run by the government?

No. QuickWhere is an independent site that uses public government data. Confirm anything official with your county or state government.
