One of the greatest things about living in America is the ability to have our voices heard on local, state and national levels by voting in elections. But first, you must register to vote with your county election authority.

Am I Eligible?

The qualifications are easy! If you are a U.S. citizen and a Missouri resident who is at least 17 and ½ years old (18 years old by election day), you are able to register.

Where do I register?

Voter registration is widely available in Missouri. You can register by mailing the online application to your local election authority, requesting an application by mail, or in person where state services are administered.

Online—You may access the registration form at . Just be sure to print the request as soon as you complete it, as registration forms cannot be saved or submitted online.

When Should I Register?

Registration requests close about 1 month prior to election dates.

However, it is always a good idea to register, even if you are unsure you would like to vote. Voter registration only needs to be renewed or updated if you change addresses. Therefore, even if you think you’re currently uninterested in political happenings, you would have the ability to vote if an issue suddenly sparked your interests!

Additionally, as registration deadlines draw near, election authorities across the state receive many registration requests. To ensure your registration is approved on time, it is smart to register well in advance of an election.

Lastly, registered voters receive the opportunity to work as election judges. For more information on election judges visit:
