The Missouri Voter Address Change Form is a document used to update a voter's residential address with the Missouri Secretary of State. This is a crucial step for any voter who has recently moved to a new residence, as their voter registration must reflect their current address in order to be valid. There are two types of Missouri Voter Address Change Form. The first is the Voter Registration Change Form, which may be completed online, printed, and mailed to the Missouri Secretary of State. The second type is the Absentee Ballot Request Form, which must be completed and returned to the local election authority in order to receive a ballot by mail.
