How do I vote if I'm in the military or live overseas?
Active-duty military, their families, and overseas citizens can register to vote and request their absentee ballot using the Federal Post Card Application (FPCA). The FPCA process is done by mail, but your state may offer other options to request and return ballots. Please contact your local election office for more information about delivery and return methods, including email, fax, and state online portals. To follow the FPCA process:
- Fill out the Federal Post Card Application (FPCA), or download a copy. Your local election office may have questions, so please provide an email address or phone number where they can reach you.
- Send the application to your local election office.
- It is never too early to submit an FPCA! Please do so as soon as possible.
- Please fill out and send back your ballot as soon as you receive it.
- States begin mailing absentee ballots at least 45 days before Election Day. If you haven't received your ballot by 30 days before Election Day, contact your local election office.
If your ballot does not arrive after you submit your FPCA, contact your local election office first. Then:
- You can still vote using the Federal Write-In Absentee Ballot (FWAB). Print, sign, and mail your FWAB to your local election office.
- If you mail a FWAB and then receive your regular absentee ballot, you should complete and mail your absentee ballot also. Election officials will ensure that only one ballot is counted.
The Federal Voting Assistance Program offers additional information on military and overseas voting in Missouri. You can also call 1-800-438-VOTE (8683) or email vote@fvap.gov
