How to Register, Vote and Track Your Ballot in Missouri

En español |  Missouri offers several ways to register to vote, including online, by mail and in person. Voters must meet certain criteria to get an absentee ballot, and most will need a notary. 

The state’s Nov. 8 general election decided races for seats in the U.S. House and Senate and the state legislature, among others.

• Upcoming elections:  Information about upcoming elections is not yet available, but will be published on the Missouri elections website.

• Voting at the polls: Polls are open from 6 a.m. to 7 p.m. Find your polling place on the state elections website.

A 2022 election law requires voters to present a valid photo ID when casting a regular ballot in person, allows no-excuse absentee voting two weeks before an election and bans the use of drop boxes. Also, the state's redistricting plan has redrawn certain congressional and state legislative districts, and may affect which candidates appear on your ballot.

• In person: Register in person or drop off a completed registration form at your local election authority. Or register at a local library, a driver’s licensing center or at other state agencies listed on the secretary of state’s website. If you register in person, you’ll need to present a valid form of ID, such as a driver’s license or U.S. passport.
  
• Online: Use the state’s voter registration portal. You’ll be asked for your driver’s license number (if you have a license) and the last four digits of your Social Security number.

• By mail: Download and print a voter registration form from the secretary of state’s website, then complete it and mail it to your county election authority. You can also fill out an online form to have an application mailed to you, or contact your election authority to ask that they mail you a ballot.

Check your voter registration status through the state’s voter information portal.

Visit your election authority to request and submit an absentee ballot without an excuse. Be sure to bring a valid ID.

Absentee ballots are only available to certain voters, including people with an illness or disability or who will be out of town on Election Day.
