The Missouri Voter Registration Application is a document used by eligible voters in the U.S. state of Missouri to register to vote. The application is used to register for both state and federal elections. There are two types of Missouri Voter Registration Applications: mail-in and in-person. The mail-in application can be completed online or by mail. The in-person application must be completed in person at a local election official’s office. The application requires applicants to provide personal information including name, address, date of birth, and Social Security number. Applicants must also declare their party affiliation if they wish to vote in a primary election. Upon completion, the application must be signed and submitted with a valid form of identification.
