Congressional districts and state legislative districts

This site covers U.S. congressional districts, the 435 seats in the U.S. House of Representatives. Every state also has its own state legislative districts, which elect members of the state house and state senate. They are drawn separately, use different boundaries, and are numbered independently, so your congressional district number and your state house district number will usually be different.

Use the lookup above for your U.S. House district. To find your state legislative districts and the people who hold those seats, use the USAGov directory of elected officials.

The House right now

The Office of the Clerk lists 218 Republicans, 214 Democrats, 1 independent, and 2 vacancies. Six more seats belong to non-voting delegates from the District of Columbia and five territories.

The two vacant seats are Florida’s 20th and Texas’s 23rd. The vacancies page covers each one and the two Senate special elections this November. A vacant district keeps a staffed office under the supervision of the Clerk, and that office can still help with federal agency casework, but the district has no vote on the floor until the seat is filled.

District lines are normally redrawn once a decade after the census. That pattern broke in the current cycle. Since the summer of 2025, ten states have changed their congressional maps between censuses: Alabama, California, Florida, Louisiana, Missouri, North Carolina, Ohio, Tennessee, Texas and Utah. If a lookup result does not match the district you voted in earlier this year, that is usually why. New lines take effect with the next Congress in January 2027.

Frequently Asked Questions

What congressional district am I in?
Your congressional district is determined by your home address, not by your city or county. Enter a ZIP code or a full street address in the lookup at the top of this page and it will return your district, the House member who represents it, and how to contact that office. A full street address gives an exact answer, because a single ZIP code can cross into more than one district.
What is a congressional district?
A congressional district is a geographic area represented by a single member of the U.S. House of Representatives. There are 435 congressional districts across the United States, and each one has roughly the same population (about 760,000 people based on the 2020 Census). District boundaries are redrawn every ten years following each decennial census through a process called redistricting.
How do I find out what congressional district I live in?
The easiest way to find your congressional district is to enter your ZIP code in the lookup tool at the top of this page. Your ZIP code will be matched to geographic coordinates, which are then used to identify your congressional district and representative.
How many congressional districts are there in the United States?
There are 435 congressional districts in the United States. This number was fixed by the Permanent Apportionment Act of 1929. Each state is guaranteed at least one district. States with smaller populations have a single at-large district, while larger states like California (52 districts) and Texas (38 districts) have many more.
What is redistricting and when does it happen?
Redistricting is the process of redrawing congressional district boundaries. It happens every ten years, after the U.S. Census Bureau completes its decennial population count. The most recent redistricting occurred after the 2020 Census, with new maps taking effect for the 2022 elections.
Can my congressional district change?
Yes. Congressional districts change through redistricting after each decennial census. If your state gains or loses a House seat due to population changes, all district boundaries in the state are typically redrawn. Court orders can also force mid-decade redistricting in some cases.
