Who is my congressman?

One representative, two senators

Every address in the United States sits inside exactly one congressional district, which elects a single member of the House every two years. The same address is also inside a state, which elects two senators on six-year staggered terms. So you have three members of Congress, and all three answer to you.

Congressional districts were redrawn after the 2020 census and several have been redrawn again by state courts since. A ZIP code can straddle two districts, so where the crosswalk is ambiguous we show you both and let you pick the one that matches your street.

House or Senate — who to write to

Write to your House member for anything tied to your district: a federal agency problem, a local project, a specific bill in the House. Write to your senators for nominations, treaties, and Senate votes, and for statewide matters. On a live bill it is worth writing to all three, because they vote in different chambers at different moments.

• House members: 435, two-year terms, district-based casework.
• Senators: 100, six-year terms, statewide and confirmation votes.
• Delegates from DC and the territories can speak and sit on committees but cannot vote on final passage.

How congressional offices count your message

Offices tally incoming contacts by issue and position, and that tally is genuinely read in weekly staff meetings. What moves the tally is a message from a verified constituent address in your own words. Form letters are counted, but in a separate and much less persuasive bucket.
