Missouri voters can check their registration status online ahead of midterm elections on November 3, 2026. Residents can confirm whether they are registered and find their polling place from the Missouri Secretary of State website. The voter registration deadline was October 7.

How to check your voter registration

You can visit the Missouri voter registration lookup website to check their records. The lookup tool will ask for details, including the voter's name, date of birth and other information. For example, a voter registered as “Penelope” may not appear if they enter “Penny” instead. The state also allows residents to contact their local election authority if they cannot find their record online.

How to find your Missouri polling place

The Missouri Secretary of State advises voters to confirm their assigned location before Election Day. In some cases, a voter may not be able to cast a regular ballot at a polling place that is not assigned to them. Voters can also use the state's Go Vote Missouri website to find their local election authority and other voting information.

Can Missouri residents still vote before November 3?

Registered voters can still vote early in person through Missouri's no-excuse absentee voting period.

According to the Missouri Secretary of State, this period runs from the second Tuesday before Election Day through the day before the election. Voters can cast a ballot at a location designated by their local election authority. They must bring an accepted form of photo identification.
