Results appear in under 2 seconds for any location worldwide.
What Is a County and Why Does It Matter
A county is a geographic and administrative subdivision of a state or country. In the United States, counties are the primary divisions of a state โ New York state has 62 counties, Texas has 254. They govern local services including elections, property records, courts, and public health. Knowing your county is required for voter registration, jury duty, property tax records, local business licensing, and many government services.
Outside the US, the equivalent division has different names. In England it's a county or district. In India it's a district. In France it's an arrondissement or dรฉpartement. In Germany it's a Landkreis. This tool returns the correct local name for each country automatically.
How the Location Detection Works
When you click Detect My Location, the browser's navigator.geolocation.getCurrentPosition() API reads your device's GPS (on mobile) or network position (on desktop). The coordinates are sent to OpenStreetMap Nominatim's reverse geocoding API, which returns a complete address breakdown including county, city, state, postcode, and country. No other service is involved.
For manual address search, Nominatim performs forward geocoding โ it converts your typed address into coordinates, then returns the full location breakdown for those coordinates. Both methods use the same free, open-source mapping service used by hundreds of thousands of applications worldwide.

What County Am I In โ Works Worldwide
The tool returns the most relevant administrative division for any country. In the United States, that is the county. In India, it returns the district and state. In the United Kingdom, it returns the county or ceremonial county. In Australia, it returns the local government area and state. In Canada, it returns the municipality and province. The field labels adjust based on the country detected.
How Accurate Is the County Detection
On a smartphone with GPS enabled outdoors, your position is typically accurate to within 5 to 15 metres โ far more precise than any county boundary. On a desktop using Wi-Fi network location, accuracy ranges from a few hundred metres to a few kilometres in dense urban areas. Both are accurate enough for county detection in virtually all cases. In rare situations where you're very close to a county boundary, the accuracy of your device GPS determines which side of the line you fall on.
