What city, county and districts am I in?
Type an address to see its city, county, ZIP code, congressional district, state senate and state house districts and voting precinct, using the maps in force for the November 3, 2026 election. Free, and your address isn't stored.
What you'll see
Your city or town (or that you're in an unincorporated area), county, ZIP code, congressional district, state senate and state house districts, and voting precinct. Each links to a page with more detail: which ZIP codes a city covers, which counties a district spans. In Canada, "Use my location" shows your province, federal riding and polling division.
Officials shown: members of Congress serving now (until January 3, 2027), state legislators, and the mayor where known. For your polling place, check your county election office.
Questions
What congressional district am I in?
Type your street address above. The lookup finds your address's coordinates with the free U.S. Census Geocoder, then checks them against the congressional district maps in force for the November 3, 2026 election, including the 2025–26 mid-decade redraws.
What are my state senate and state house districts?
The same lookup returns your state senate and state house (assembly, house of delegates) districts under the 2026 legislative maps. Nebraska has a single-house legislature, so it shows only one.
What is my voting precinct?
The lookup shows the precinct your address falls in, from the current official precinct file where your state or county publishes one, else the 2020 Census voting district. Confirm your polling place with your county election office; precinct lines change between elections.
Am I inside city limits?
If your address is inside an incorporated city, town or village, the lookup names it. If it names a Census-designated place, or no city at all, the address is in an unincorporated area served by the county.
Does this work in Canada?
Use "Use my location": it returns your province, federal riding, federal polling division and provincial district. Typed addresses are US-only for now, because the free geocoder covers the US.
Do you keep my address?
No. Your address is sent to the U.S. Census Geocoder to find its coordinates, and the answer comes back to your browser. Boundary Atlas doesn't store it or put it in any log.
