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. The deadline for your application to be received is March 21st.

  • 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.
  • Or return your ballot by mail to your local election authority so that it is received by 7 p.m. on April 6th. 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 6th - your ballot will not count.
