Which States Have New Congressional Maps for 2026? The Full List, With Dates

Ten states have enacted new U.S. House maps for the November 3, 2026 election — 181 districts in all. This page is the reference list: each state’s plan, the vehicle that adopted it, the date it took effect, and where its litigation stood on August 20, 2026. The other 40 states and the District of Columbia vote on the boundaries used in 2024.

Reading the Status Column

“Under challenge” means a lawsuit is pending, not that the map is in doubt for November. In each state, courts have so far allowed the 2026 election to proceed on the enacted lines even where the underlying dispute is unresolved. Missouri’s remaining question concerns whether a referendum petition qualified, not which map the state uses this year. Utah’s map was adopted by a state court rather than the legislature, which has appealed; it governs the 2026 election while the appeal proceeds.

Alabama’s is the map that moved furthest from the one its delegation was elected on. The sitting delegation was elected on a court-ordered plan drawn after Allen v. Milligan; the map in use for November is the legislature’s 2023 plan, which the Supreme Court allowed back for this cycle. For some Alabama addresses, the sitting representative and the November district do not correspond.

Every status above carries its date for a reason. Litigation moves; a court can change which map a state uses. A status without an as-of date is a claim about the past dressed as a claim about the present.

Where the Official Boundaries Live

Each state publishes its own enacted plan: Texas through its Legislative Council (PLANC2333), California on the state’s redistricting database (the Proposition 50 map), Florida through the state Senate, Louisiana through its legislature’s redistricting site, North Carolina through the General Assembly, Ohio through its redistricting commission’s mapping portal, Tennessee through the Comptroller, Missouri through its state spatial data service, Alabama through the Secretary of State, and Utah through the state’s geospatial resource center.

The Census Bureau’s consolidated version — TIGER/Line shapefiles for the 120th Congress — is scheduled for September 2026 and reflects boundaries in effect January 1, 2026, as submitted by the states. Four of the ten plans (Florida, Tennessee, Louisiana, Alabama) were enacted or certified after that reference date, and the bureau’s schedule does not say whether they will appear in the September files. Until then, most commercial address tools answer from the current TIGER vintage, which carries the 119th Congress lines — the districts of the seated members, not the districts on November’s ballots. Why that gap exists, and how to check a file for it, is its own article.

Checking a Single Address

For one address, the free lookup on this site returns the congressional district serving it today and — in the ten redrawn states — the district it votes in for 2026, with that state’s status and the date the status was last checked. What Congressional District Am I In? covers the official lookup routes.

RevAddress, which publishes this site, maintains both sets of boundaries — the Census files for the seated Congress and each redrawn state’s enacted plan for November. For a file of addresses, Campaign File Clean returns both districts on every row. The company calls each row’s result a reading, and says a reading describes the address — its districts and its representatives — never the household or the person at it. It does not sell, source or append voter data.
