Request and track
Notice: Mail-in voting is a convenient and safe way to vote, but your ballot might not count if it’s submitted late or with errors. So follow the directions below on how to vote early or absentee and make your vote count in Missouri.
Excuse required to vote by mail.
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 October 26th.
Step 2: Complete and return your ballot ASAP.
The absentee ballot envelope must be signed by a notary, election official, or other authorized oath administer.
Remember to sign your return ballot.
Wait! Don't sign your ballot until you find a notary. You must sign the statement on the return envelope in the presence of a notary. They must sign the ballot, too.
If you return your ballot by mail, your postage is prepaid.
You can also drop off your ballot in person at your local elections office.
Close relatives may return a ballot on your behalf.
If you have an unused mail-in ballot and decide you would like to vote in person go to your polling site on Election Day. Bring your mail-in ballot if possible. The poll worker will confirm that your mail-in ballot was not used before allowing you to vote in person.
Missouri does not offer voters a chance to address challenges to their ballot. Your ballot will not count if it is late, or you do not follow directions.
