Note: In-person early voting is sometimes referred to as 'in-person absentee', 'over-the-counter voting', 'assisted voting', or other similar titles. These are all essentially the same kind of voting and will be discussed as one in this section.
For the upcoming {{ next_election_name }}, any registered voter may vote early in person.
In-person early voting may happen in a variety of locations like county election offices, city halls or municipal buildings, public libraries, schools, and community centers. It’s important to note that the availability of early voting can vary significantly by state or even county. They may also change from election to election, so be sure to check your early voting location before you head to the polls.

*If the driver or non-driver license has expired after the most recent general election, it is an acceptable form of voter ID.
It’s extremely important to have the appropriate ID when you go to your polling place to vote. However, if you’re not able to present one of the required forms of identification, ask a poll worker about what options you have to vote via provisional ballot.
A provisional ballot gives you the opportunity to vote when your voter registration is not able to be verified. After Election Day, election officials will attempt to verify that you voted in the correct district. This option is only recommended in exceptional circumstances – for example, you forgot your voter ID and you won’t be able to make it back to your polling place before it closes.
Election Day voting hours are 6:00 AM to 7:00 PM at all polling places statewide in Missouri.
The Help America Vote Act of 2002 states that election officials conducting federal elections must ensure that each polling place has at least one accessible voting system for individuals with disabilities. This system should provide the same level of privacy and independence as those available to other voters.
Plan ahead by getting in touch with an election authority at the state, county, or municipal level to learn more about what specific accommodations are available at your polling place.
