How to Find My County
-
Turn the "Location services" switch to ON.
-
Allow the browser to access your device's location data.
-
Your current location will be marked with a blue icon on the map, and your county will appear in the County field.
Using the Tool
Can I zoom in or out on the map?
Yes, you can zoom in or out on the map. To do this:
-
Click or tap the + button on the map toolbar to zoom in.
-
Click or tap the − button on the map toolbar to zoom out.
Can I view the map in full screen?
Yes, you can view the map in full screen by clicking or tapping the "View Fullscreen" button on the map toolbar.
Can I share my current county data?
Yes, you can share your current county data by clicking or tapping the "Share my location" button. Your location details, including the county, address, latitude, longitude, country, state, city, and ZIP code, are included whether you're using a phone or a computer.
What if I'm traveling across county lines?
The tool checks your location when the page loads. After you've moved, refresh the page to see your current county.
Accuracy and Troubleshooting
How accurate is the county detection?
Accuracy depends on two things: how precisely your device can find you, and how your county is looked up. The tool uses your device's GPS through your browser's location feature. Phones and tablets with GPS are typically accurate to about 5 meters (16 feet) outdoors, though accuracy drops indoors and near tall buildings or trees. Laptops and desktops usually estimate your position from nearby Wi-Fi networks, which can be accurate to the neighborhood level. Your county, address, and ZIP code then come from OpenStreetMap's Nominatim service, which looks up the nearest mapped place and returns its details rather than calculating them for your exact spot. Very close to a county line, that can occasionally mean the neighboring county, and the address may belong to a nearby building or even a different street.
Which devices work best with this tool?
It works on all modern devices, but mobile phones and tablets with GPS offer the highest accuracy. Laptops and desktops usually don't have GPS, so they rely on Wi-Fi positioning, which can be less precise near borders.
How can I improve accuracy if I'm near a county border?
If the map shows county lines, zoom in to see which side the blue icon is on, but remember the icon is an estimate. For the best reading, step outside with a clear view of the sky, give your phone a few seconds to settle, and make sure your browser can use your precise location. On iPhone, that's Settings > Privacy & Security > Location Services > Safari Websites > Precise Location. On Android, turn on "Use precise location" in Chrome's location permission. If you need a definitive answer for taxes, voting, or permits, look up your address on your county's official property or GIS map.
Why does the tool sometimes show "Nothing found" for my county?
This can happen if location permission isn't granted or your device can't get a location fix (for example, indoors or in areas with poor coverage). It can also happen in the 41 U.S. independent cities, which aren't part of any county (such as Baltimore, St. Louis, and Richmond, Virginia). There, the County field may be blank or show the city itself. Refresh the page after moving to an open area or re-enabling permissions.
Location Access and Privacy
Can I use this tool without enabling location services?
No. The tool needs location access to work. It uses your device's GPS (or, on devices without GPS, the Wi-Fi or cell-tower data your browser provides) to find your coordinates and determine your county. Without location access, it can't detect your position, so it won't show your county or address or mark your location on the map.
Is my location data private?
The tool doesn't save your location or keep a history of it. To find your position, your browser works out your coordinates (some browsers, such as Chrome, use an online location service for this). The map is built with Leaflet, an open-source library that runs in your browser. Like any online map, it downloads tiles for the area around you from a map provider. To show your county, address, and ZIP code, the tool also sends your coordinates to Nominatim, OpenStreetMap's free public geocoding service. As with any web request, Nominatim sees your IP address too. We use analytics cookies and may show ads from third-party partners that set their own cookies, as many free sites do. See our Privacy Policy for details.
Availability and Limits
Can I search for a county by entering an address?
No. The tool only shows the county for your current location, but you can zoom and pan the map to see the surrounding area.
Does the tool work outside the United States?
While primarily designed for U.S. counties, it functions globally by detecting the local equivalent of a county, such as a district in India or a département in France. In places without a county-level division, the County field may be blank.
Does the tool work offline?
No. Your phone's GPS can find your coordinates without a connection, but the tool needs internet to load the map and to look up which county those coordinates are in.
Is the tool free, and does it have ads?
Yes, the tool is free and doesn't require registration. The site may show non-intrusive ads, and the tool runs smoothly on most connections.
