Location Tools
Find your exact place — county, city, state, congressional district, or township — from your GPS location or a street address. Every tool resolves against official U.S. Census boundaries, not crowd-sourced maps, and returns real data, not just a name.
Which tool answers which question?
All six tools — what you get, when to use them
- What county am I in?Your exact county from GPS, address, city, or ZIP — with its population, median income, unemployment, and county seat.When: Taxes, voter registration, court jurisdiction, or any form that asks for your county.
- What city am I in?The city, town, or community your location falls in — incorporated place or unincorporated area.When: When you need the municipality, not the county.
- ZIP-to-county lookupEvery county a ZIP code touches, with each county’s share of that ZIP’s addresses, from HUD data.When: When a ZIP spans county lines and you need all of them.
- What state am I in?The state or territory for any location or address, with a link to its full county atlas.When: Near a state line, or confirming which state has jurisdiction.
- My congressional districtYour U.S. House district for the current (119th) Congress, from your location or address.When: Contacting your representative or checking your district.
- What township am I in?Your civil township or minor civil division — the layer of local government below the county.When: In the roughly 20 states with township government.
How every tool works
Each one sends your location or address to the U.S. Census Bureau’s geocoder, which point-in-polygon-tests it against the official TIGER/Line boundaries and returns the geography you asked for. CountyAtlas then adds the real figures — population, income, unemployment, county seat — from the same primary sources behind the county maps.
