How to Find Your District
Enter your home address on the Indiana General Assembly’s legislator-lookup tool at iga.in.gov. The U.S. House runs a similar tool at house.gov. Either returns your representative’s name, contact information, and office locations. District lines run through the middle of some counties and even some cities, so your neighbor across the street could be in a different district. Checking by address, not by city or county, is the only reliable method.
How the Current Map Was Drawn
The Indiana General Assembly draws congressional boundaries through the normal legislative process: a redistricting bill passes both chambers and goes to the governor. In the most recent cycle, the legislature passed House Enrolled Act 1581 on October 4, 2021, and the governor signed it the same day.2Indiana General Assembly. Indiana Redistricting Process Those maps took effect for the November 2022 elections and will govern Indiana’s congressional elections through the end of the decade.
Indiana law requires that congressional districts be established during the first regular session of the General Assembly after each federal census.11Indiana General Assembly. Indiana Code Title 3 Article 3 Chapter 2 – Section 3-3-2-1 The Indiana Constitution also requires districts to be contiguous, so every part of a district physically connects to the rest.12Justia Law.

Running for a Seat
Three constitutional requirements apply to anyone seeking an Indiana U.S. House seat. A candidate must be at least 25 years old, must have been a U.S. citizen for at least seven years, and must live in Indiana at the time of the election.14Constitution Annotated. Overview of House Qualifications Clause The age and citizenship thresholds have to be met by the time the winner takes the oath, not by Election Day. Neither Congress nor the state can add further qualifications.
Separately, candidates must satisfy Indiana’s ballot-access rules, which include filing paperwork with the Secretary of State and collecting a required number of petition signatures. Filing fees and signature thresholds vary by party affiliation and election type, and they are set by state law rather than the federal Constitution.
