The Official Election Day Schedule
Across the entire state of Missouri, polling places operate on a uniform schedule. Polls officially open at 6:00 a.m. Central Time and close at 7:00 p.m. Central Time. This 13-hour window applies to all general elections, primary elections, and special elections held within the state, ensuring consistency whether you live in a dense urban center or a rural county. It is essential to plan your day accordingly, as arriving before 6:00 a.m. or after 7:00 p.m. will mean you are outside the official voting hours. Local election authorities work to ensure every location is ready to begin processing voters promptly at the opening time.
What if I'm Still in Line at 7:00 p.m.?
This is one of the most common questions voters have, and Missouri law is very clear on the matter: if you are in line
at your polling place by 7:00 p.m., you have the right to vote. Election officials are required to allow every voter who was in the queue at the moment of closing to cast their ballot. An election judge will typically stand at the end of the line at 7:00 p.m. to mark the cutoff point. So, if you find yourself in a long line as the deadline approaches, do not leave. As long as you were there on time, your vote will be counted.
What to Bring: Missouri's Voter ID Rules
Missouri has a photo ID requirement for voting. Before you can receive a ballot, you must present an acceptable form of identification. These include a non-expired Missouri driver's license or non-driver license, a non-expired military ID (including a veteran's ID card), or a non-expired United States passport. Other photo IDs issued by the state of Missouri or the U.S. government are also accepted. If you are a registered voter but do not have one of these forms of ID, you can still cast a provisional ballot. That ballot will be counted if you return to the polling place later that day with a valid photo ID, or if election officials can match the signature on your provisional ballot envelope to the one in your voter registration record.
How to Find Your Assigned Polling Place
You can only vote at the specific polling place assigned to you based on your registered address. Voting at the wrong location could result in you having to cast a provisional ballot or being redirected to the correct site. To avoid any confusion on Election Day, you should verify your polling place in advance. The Missouri Secretary of State’s website offers a 'Voter Outreach Portal' where you can enter your information to confirm your registration status and find your designated polling location. Many county election boards also offer online tools to look up this information. Checking this a week or two before the election can save you significant time and stress.
Alternatives: No-Excuse and Absentee Voting
For those who prefer to vote before Election Day, Missouri offers a couple of options. The state has a period for no-excuse in-person absentee voting, which begins on the second Tuesday before an election. During this window, any registered voter can go to their local election authority's office or a designated satellite location to cast their ballot without needing to provide a reason. For those who qualify under specific excuses—such as being absent from the county, illness or disability, or religious belief—traditional absentee voting is available starting six weeks before an election. Ballots can be requested by mail, but they must be received by your local election authority by 7:00 p.m. on Election Day to be counted.
