Military and overseas voters

Active-duty military, their families, and voters living outside the US can register to vote and request their absentee ballot using the Federal Post Card Application (FPCA). To do so:
  1. Fill out the Federal Post Card Application (FPCA), or download a copy. Your election official may have questions, so please provide an email address or phone number where they can reach you.
  2. Send the application to your election official.
  3. It is never too early to submit an FPCA! Please do so as soon as possible. You can look up recommended mailing dates by country and region.
  4. When your ballot arrives, read it carefully and follow the instructions to complete it and return it.
  5. 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 after submitting your FPCA, your ballot does not arrive, contact your election official 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 – FVAP.gov offers additional information on military and overseas voting in Colorado.
