Find out what county (or parish/borough) you're in right now, using your device GPS. Works worldwide; uses US Census data in the US and OpenStreetMap elsewhere. Free, runs in your browser.
Frequently Asked Questions
How does this tool know what county I am in?
It uses your browser's geolocation to get your latitude/longitude, then queries the US Census Geocoder to find the county that contains your point. Outside the United States, counties aren't a standard administrative division, so the tool falls back to showing the equivalent second-level administrative region (district, municipality, etc.) from OpenStreetMap.
Why does it ask for my location?
Your browser asks permission before sharing your GPS coordinates. Click "Allow" to use your real location, or click "Deny" and type any address or coordinate manually in the input box. Your location is processed in your browser — it is shared only with the US Census API for the county lookup.
Is the county accurate to my exact spot?
Yes — county boundaries are precise polygons, not approximations. The Census Geocoder does a true point-in-polygon lookup, so the result is correct to within centimetres. The same cannot be said for IP-based geolocation (which can be off by kilometres on a VPN).
What is a county, exactly?
In the United States, a county is the primary administrative division of a state — there are 3,143 of them. Louisiana calls them "parishes" and Alaska calls them "boroughs"; this tool uses those local names where appropriate. The equivalent level elsewhere is the UK's "ceremonial county", Canada's "census division", or Australia's "local government area".
