Voter Eligibility & Registration
Who Can Register?
Any Missouri resident who is a US Citizen, will be 18 by Election Day, has not been declared legally incompetent, and is not currently serving time, or on probation or parole from a felony conviction, can register to vote.
When Should You Register?
When you turn 18 (or at age 17 1/2 if you will turn 18 by Election Day)
If you’re age 18 or older and have never registered
When you attain eligibility by becoming a US citizen or regain eligibility by getting “off paper” from a felony conviction
When you move to Missouri from another state
What is the Deadline?
New voters must register to vote at least 4 weeks prior to the election date in order to be eligible to vote in that election. There are limited exceptions for people who move to Missouri after the voter registration deadline; those people should contact their local election authority or 1-866-OUR-VOTE (a non-partisan voter help hotline).
Updates to an existing registration, like a name change, an address change within the same county/election jurisdiction, or reactivating from inactive status, can be done anytime, including on Election Day. Missouri voters who move to a new county can update their registration and vote on Election Day, but may need to do so at their election authority office.
