in
A few weeks before the election, Colorado will mail a ballot to every voter registered at least eight (8) days before Election Day. Keep an eye on the mailbox! Be sure to mail it back so that it is received by Election Day, or drop it in a drop box before or on Election Day! You can also vote in person during early voting and on Election Day if you prefer to do so. If you register to vote less than eight (8) days before Election Day, you can vote in person.

To register in Colorado you must:
  • be a citizen of the United States

      How do I vote by mail?

      Colorado conducts elections primarily by mail. If you are an active registered voter and you submitted your voter registration application at least eight days before Election Day, then you can expect to receive a ballot in the mail. It will be sent to the mailing address on your voter registration file.

      If you are voting by mail for the first time, you may also need to provide a copy of your ID when you return your mail ballot. For more information, please visit the Colorado Secretary of State's website.

      What should I do if I don’t get my ballot?

      If you don’t receive your ballot in the mail, then contact your local election office. You can also vote in person at a voter service and polling center.

      How do I return my ballot?

      What do I need to do if I’ve moved?

      What’s on your ballot depends on where you live, so your voter registration is tied to your exact address. If you’ve moved, you need to re-register with your new address.

      How can I check the status of my ballot?

      You can check the status of your ballot on Colorado’s site.

      Can I register to vote on Election Day?

      Colorado does offer in person registration on Election Day.

      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:
      1. 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.
      2. Send the application to your local election office.
      3. It is never too early to submit an FPCA! Please do so as soon as possible.
      4. Please fill out and send back your ballot as soon as you receive 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 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 Colorado. You can also call 1-800-438-VOTE (8683) or email vote@fvap.gov
