The ACLU of Missouri works in the courts, legislature, and communities to defend and preserve the individual rights and liberties under the Constitution, including your right to vote. That includes making sure you have access to information about how to exercise your right to vote and where to get help if you experience a barrier or threat to this tool of democracy.
Your vote is your voice. Voting is the cornerstone of our democracy and the fundamental right upon which all our civil liberties rest.
Your vote will determine what laws and which lawmakers will impact taxes, health care, safety, education, justice, infrastructure and more.

Absentee Voting by Mail
You may request to vote absentee by mail by sending an application for a ballot up to 10 weeks in advance of the election but no later than the second Wednesday prior to the election. Ballots will be mailed to voters 6 weeks prior to any election.
No-Excuse Absentee Voting (in-person)
Missourians now have two weeks of no-excuse in-person absentee voting. Voters will need to provide a non-expired state or federally issued photo identification when voting no- excuse in-person absentee. Contact your local election authority to learn how you can cast your no-excuse in-person ballot.

Acceptable forms of Identification for Voting
While we are challenging the voter restrictions that recently went into effect, it is crucial that you are registered and have the proper identification in order to cast your ballot.
You can vote an absentee ballot without your voter identification card as long as you are a registered voter. Voting absentee does not guarantee your vote will be counted. Provisional ballots will only be counted if you return to the polls with the proper identification or your signature must match the signature on record.
Show one of the forms of acceptable identification and sign the poll book to ensure your vote is counted:
- Photo Identification issued by the State of Missouri, United States government or agency
Protection & Advocacy for Voter Accessibility
Protection & Advocacy for Voter Accessibility (PAVA) is part of the federally mandated system to protect the legal rights of persons with disabilities through legal-based advocacy. PAVA services are available to individuals in Missouri who have a disability and need help to fully participate in the voting process, including:
- Registering to vote
- Casting a ballot
- Accessing your polling place
