•A nonexpired military ID, including a veteran’s ID card;
•A nonexpired United States passport; or
•Another photo ID issued by the United States or the state of Missouri which is either not expired or expired after the date of the most recent general election.
You can still use one of the listed IDs if it expired after the most recent election. For more information about Missouri’s voter ID rules, visit: https://www.sos.mo.gov/voterid.
If you registered to vote by mail, have not voted in person before, and requested to vote by mail, you will need to submit a copy of an acceptable ID with your absentee ballot request form. This requirement does not apply if you are located overseas, are on active military duty or living with a family member who is, or have a permanent disability.
