Your District May Have Changed This Election Season. Here’s What to Do Before You Vote

Confirming your polling place and researching candidates is a smart move — even if your state is not redrawing lines

Key takeaways

  • Ten states have revised congressional maps since summer 2025, with additional states considering it or in litigation.
  • Redistricting may change your polling place, election date or candidates on the ballot.
  • Checking the location 30 days out, and voting early or by mail can help avoid voting issues.

Ensuring your vote counts gets trickier if the time, place or people you’re voting for changes. Those short-notice election shifts are likelier to happen this year because of redistricting taking place in some states.

Redistricting — the process of redrawing the lines around electoral districts to ensure each one contains roughly the same number of voters — typically happens once every decade following a census count. Recently, there has been an unusual flurry of activity that could trip up voters when it comes time to cast their ballots.

Ten states have changed their congressional maps since the summer of 2025, according to the National Conference of State Legislatures (NCSL), while several others are starting the process or considering it. If your state is one of them, that means your polling location or election dates could change, or you may be voting for a different U.S. House representative from the one you expected.

Right now, some states are modifying their congressional lines, meaning only U.S. House seats are affected. There are also electoral districts for state legislatures, county commissions and city councils. 

Join Our Fight to Make Sure Your Vote Counts

AARP is a nonpartisan organization that never supports or opposes candidates for office. We believe the right to vote is fundamental, and we advocate for policies ensuring that Americans 50 and older can exercise that right without unnecessary barriers. Here’s what you can do to help:

Katy Owens Hubler, director of elections and redistricting at the NCSL, says that she expects to see redistricting continue over the next couple of years with House races and that it could carry over to state and local races as well. In 2024, 10 states had new congressional or legislative maps in place, according to the Redistricting Data Hub, an online data source. 

“The biggest thing is to stay informed,” says Owens Hubler. “People may throw up their arms and say, ‘Things are changing so quickly so I’m not going to pay attention.’ But it’s important to pay attention to deadlines and know what’s on your ballot.”

Follow these steps to avoid hiccups when casting a vote. They’re useful whether your state is experiencing redistricting or not, to make sure your vote counts.

Confirm your polling place

Districts, the geographic areas where people vote for a particular candidate, are often subdivided into smaller areas called precincts.

Justin Levitt, a law professor at Loyola Law School in Los Angeles, likens precincts to molecules or building blocks. Precincts typically have a single polling place for residents, although sometimes more than one precinct will vote in the same location. (If your city or county uses a “vote center” model, where people can choose from several locations rather than having a single designated spot, the specific location you go to doesn’t matter because you will receive an individualized ballot when you arrive.)   

When states redraw district boundaries, Levitt says, “the races you see on the ballot may be different, but they tend not to mess with precincts or polling places.”

Finding new polling places that fit accessibility and proximity requirements can be tough, so election officials try to avoid switching. But it can still be necessary if a district line cuts through a precinct or if a state needs to even out the number of voters, says Owens Hubler.

It’s a good idea to double-check whether or not your state is shuffling its map. Sometimes election administrators find the school or gym they typically use is not available, Levitt points out. “Don’t assume the place you voted last time is the place you’ll vote this time,” he says.

He suggests verifying your voter registration two months in advance and voting location 30 days before the election, when plans will be settled.

Ideally, election officials in states that are making changes will send voters information by mail, on their official voter websites, in traditional media or on social media. But this is a year to be proactive, says Owens Hubler.

Confirm your polling place with the lookup tool on your official state or local election website. If there is no lookup tool, “whoever is administering the election shouldn’t be put out by you contacting them to double-check,” says Kate Donovan, director of the Redistricting Data Hub. You can find this contact information on your state’s official voter information website as well. 

Research your candidates

Finding out who is on your ballot before heading to the polls helps you make an informed decision. It’s especially important if you are in a district where the lines have been redrawn, because you may see different names on the slate than you have in the past.

Your state may mail a sample ballot ahead of time, which will let you familiarize yourself with your options. If not, you can check your state election website for a preview or use the lookup tool at ballotpedia.org. Also, voter guides may appear in your local newspaper.

Knowing the candidates on your ballot in advance can also help you catch a mistake if election officials accidentally mail you the wrong ballot or provide you with the wrong one in person.

Check the 2026 election dates

It is unlikely that your primary dates will change, but two states have done so this year in anticipation of new maps. Shortly before early voting was set to begin on May 2, Louisiana postponed its primaries for U.S. House seats until Nov. 3. (Its general election will take place on Dec. 12 if necessary.) Elections for other ballots and office measures will continue as planned. T

A Year of Redistricting

These 10 states have changed their congressional maps since the summer of 2025.

  • Alabama
  • California
  • Florida
  • Louisiana
  • Missouri
  • North Carolina
  • Ohio
  • Tennessee
  • Texas
  • Utah

Alabama moved primaries for four congressional districts from their scheduled date of May 19 to August. The general election will be held Nov. 3. 

Voting early gives you time to course-correct if you head to the wrong polling place. Voting by mail circumvents the problem altogether. In states that provide drop boxes, this method of delivery is unlikely to be affected because they can typically be used by any voter in the county.

What if redistricting means you miss a change?

If your polling location has moved and you accidentally show up at the old one, don’t panic. Ask poll workers where to go and head there. Officials “are supposed to tell you you’re in the wrong place and give you the option of going to the right place, but it doesn’t always happen,” Levitt says.

If you can’t make it to the correct polling place and you choose to cast a provisional ballot where you are, be aware that your vote may not count at all. In some places, it may count for local races in the same district or statewide races, such as for governor. 

“There is so much variation by state about what happens if you show up at the wrong polling place,” Donovan says.

It’s best to avoid the problem altogether by doing a bit of research and preparation ahead of time.
