Document:
If you moved to Missouri from another state, you must register to vote in Missouri to be able to vote. The last day to register in time to vote in the next election is by 5 p.m. on the fourth Wednesday before Election Day.
If you moved from out of state, you may register to vote the same day you become a resident of the State of Missouri. And, under federal law, if you move within thirty days of a presidential election, you are allowed to vote for President and Vice President in your former state of residence, either in person or by absentee ballot.
Many Missouri registered voters who move are still entitled to cast a ballot that will be counted — even if they did not notify the appropriate election official about the move before Election Day.
If you moved to a new address within the same county but in a different polling place, you can change the address on your voter registration records and vote a regular ballot at the polling place on Election Day for your new address or at a central polling place after confirming your new address.
If you moved to a new address in a different county after the registration deadline, you can vote in that election by limited absentee ballot for presidential and vice presidential electors, United States senators and Congressional representatives, and statewide candidates and issues. You need to apply for absentee ballots in person at the office of the election authority for your new county by 7:00 PM on the day of the election.
If you moved to a new address in a different county before registration deadline, you should complete a new registration form to update your registration records with your new address to be able to vote in the upcoming election.
