How do I find out who my representative is?

Choose your state here to see the full House delegation with each member's district number, then confirm your own district with the official lookup at house.gov, which takes a full street address. A ZIP code alone is often not enough because one ZIP can span multiple districts.

How many members of Congress does each state have?

Every state has exactly two senators. House seats are apportioned by population after each decennial census, ranging from a single at-large seat in the smallest states to more than fifty in California. Most residents therefore have three members of Congress in total.

Does Washington, D.C. have members of Congress?

D.C. has no senators and no voting representative. It elects one delegate to the House who can serve on committees, introduce bills, and vote in committee, but cannot vote on final passage. Puerto Rico and four island territories send delegates under the same limitation.

How do I contact my senator or representative effectively?

Use the official .gov link on your state's page and include your full address, since offices weight contact from verified constituents. If a federal agency is involved — a stuck passport, a delayed VA claim, a Social Security problem — ask specifically for casework, which is a formal inquiry staff can make on your behalf.

How often is this list updated?

Daily. Alto pulls the current roster rather than election results, so appointed senators and special-election winners appear as soon as the underlying dataset records the seat change.

Why Alto asks for your state, not your ZIP code

A single ZIP code frequently covers parts of two or three congressional districts, so any ZIP-to-district lookup is either licensed data or a quiet guess. Your two senators are determined by state alone, which Alto can answer exactly, and the full House delegation is listed so you can find your own district by name. For the precise district, the official House tool resolves a full street address.

Sources

Roster, party, district, and contact details from the public @unitedstates congress-legislators dataset, which is public domain and updated within days of any seat change. Alto refreshes it daily.

Pick your state to see both U.S. senators and every U.S. representative in its delegation, each with party, district, Washington office phone, and a link to their official site. There is no sign-up and nothing to enter beyond your state.

Most Americans have three members of Congress: two senators elected by the whole state, and one representative elected by the district they live in. This page gives you the two senators exactly, and lists the full House delegation so you can find your own district.

Why this asks for your state instead of your ZIP code

ZIP codes were built to deliver mail, not to describe political boundaries, and a single ZIP routinely covers parts of two or three congressional districts. Any tool that turns a ZIP into one district is either using licensed crosswalk data or quietly picking the most likely answer. Your senators, by contrast, are determined by state alone, so that part can be answered exactly — and for the precise district, the House's own lookup resolves a full street address.

How the two chambers differ

Senators serve six-year staggered terms and represent an entire state, and the Senate alone confirms federal judges, Cabinet officers, and ambassadors and ratifies treaties. Representatives serve two-year terms and answer to a single district, and the House alone originates revenue bills and brings articles of impeachment. Every state has exactly two senators regardless of population, while House seats are apportioned by population after each census.

Where the roster comes from

Alto reads the public-domain congress-legislators dataset maintained on GitHub, which tracks the current officeholder for every seat and is updated within days of a resignation, death, appointment, or special election. That matters because a roster derived only from election results goes stale the moment a governor appoints a replacement senator. Alto refreshes the data daily and withholds the list entirely rather than showing a partial delegation if the source is unreachable.
