Austin is divided among six congressional districts: the 10th, 17th, 21st, 31st, 35th, and 37th. Because the lines cut through neighborhoods and even single streets, two neighbors can have different U.S. Representatives, and the only reliable way to confirm which of Austin’s congressional districts covers your home is an address-level lookup rather than a map at a glance.
Find Your District by Address
The Texas Legislature’s “Who Represents Me?” page takes a home address and returns every elected official who represents you, from your U.S. Representative down to your state legislators.1Texas Capitol. Who Represents Me? The U.S. House also runs a national “Find Your Representative” tool that works by ZIP code or full address; if your ZIP spans more than one district, it will ask for the street address.2U.S. House of Representatives. Find Your Representative
Communities like Pflugerville, Round Rock, Cedar Park, Kyle, and Buda are each split across two or three districts, so general boundary descriptions can mislead you. If you have moved recently, even a short distance, check whether you crossed a district line. A move between districts means a new representative, and you are required to update your voter registration with your new address. You can update online, by mail, or in person at your county election office.3USAGov. How to Update or Change Your Voter Registration
The Six Districts and Who Represents Them
Each district sends one representative to the U.S. House. The descriptions below give the general shape of each; use an address lookup to confirm.
37th District: Central Austin
The 37th is the most compact of the six, centered on the urban core of Travis County. It covers downtown, the University of Texas campus, and the dense central neighborhoods on both sides of Interstate 35. It also takes in West Lake Hills, Rollingwood, Sunset Valley, and San Leanna, plus parts of Pflugerville to the north.4Texas Department of Transportation.

What Your Representative Can Do for You
Your U.S. Representative’s office provides direct help when you hit a wall with a federal agency. If you are stuck waiting on a passport, cannot get a response from the IRS, or need help with Social Security or veterans’ benefits, the office’s constituent services staff can intervene on your behalf. You will usually need to sign a privacy release form authorizing the office to contact the agency about your case.
Congressional offices also handle requests that surprise many constituents. You can order an American flag flown over the U.S. Capitol, complete with a personalized certificate, through your representative’s office. If you are planning a trip to Washington, the office can help arrange tours of the Capitol, the White House (request at least three months in advance), and FBI headquarters. Each Austin-area representative keeps a local district office in addition to the Washington one, so you do not need to travel to D.C. for help.
