How Vote By Mail Works in Missouri

In Missouri, it is a two step process to vote by mail: Step 1: Request your ballot NOW. You must have an excuse to qualify to vote with an absentee ballot. The deadline for your application to be received is March 22nd.

  • If you have never voted in Missouri before, include a copy of your photo ID with your application.
Step 2: Complete and return your ballot ASAP.
  • Sign your ballot in the presence of a notary. They must sign it, too.
  • Return in person to your local elections office on or before April 4th, Election Day, at 7 p.m. Find your local elections office here.
  • Or return your ballot by mail to your local election authority so that it is received by 7 p.m. on April 4th. We recommend mailing your ballot at least two weeks before as the post office is not always reliable. The best intentions will not matter if your ballot is received after April 4th - your ballot will not count.
