Missouri ID requirements for voting by mail

Who is eligible to request an absentee ballot and vote by mail?

To be qualified to vote absentee, you must be:

  • Absent from your voting jurisdiction on Election Day
  • Incapacitated or confined due to illness or physical disability, or have primary responsibility of caring for an incapacitated or confined person
  • Restricted by religious belief or practice
  • Employed by an election authority at a location other than such voter's polling place
  • Incarcerated but have retained all voting qualifications
  • A certified participant in address confidentiality program because of safety concerns

Voter Registration

First-time voters who have not voted in a previous federal election, or who have never voted in their county of residence in a federal election, AND who did not provide either a driver’s license number or the last four digits of a Social Security number at the time of registration, must present documentation proving their identity in order to complete their voter registration. First time voters who are voting in person must present this documentation at the polls. First time voters who are voting by mail/absentee ballot must enclose a copy of such documentation with their ballot request or ballot. This is required under the federal Help America Vote Act, enacted in 2002.

Do you need to submit ID with your absentee ballot request?

Voters requesting an absentee ballot by mail who have registered by mail and have not voted in person are required to submit a copy of their personal identification unless they provided a copy with their registration application. Examples of acceptable identification are:

  • ID issued by state of Missouri, agency of the state, or local election authority of the state; 
  • ID issued by U.S. government or agency thereof; 
  • ID issued by institution of higher education within state of Missouri; 
  • Current utility bill, bank statement, pay check, or gov’t document including check with name and address of voter;
  • ID approved by the Secretary of State of Missouri.

Do you need to submit ID with your ballot?

No, but the signature on your mail ballot must match your voter registration signature.
