Colorado absentee ballot directionsAll registered Colorado voters receive mail ballots. You only need to apply for an absentee ballot if you need your ballot mailed someplace other than your usual address. If that's the case:
- Use our Absentee Ballot Tool to prepare your application.
- Sign and date the form. This is very important!
- Return your completed application to your Local Election Office as soon as possible. We'll provide the mailing address for you.
- All Local Election Offices will accept mailed or hand-delivered forms. If it's close to the deadline, call and see if your Local Election Office will let you fax or email the application.
- Make sure your application is received by the deadline. Your application must actually arrive by this time -- simply being postmarked by the deadline is insufficient.
- Please contact your Local Election Office if you have any further questions about the exact process.
Once you receive your ballot...
- Once you receive the ballot, carefully read and follow the instructions.
- Sign and date where indicated.
- Mail your voted ballot back to the address indicated on the return envelope.
- Your voted ballot must arrive by the deadline or it will not be counted.
- If you want to vote in-person, you may return your mail ballot and vote in-person at a voter service and polling center. Even if you do not return your mail ballot you may still vote in person. Once you vote in person your county clerk will not accept for counting any ballot that was mailed to you. The deadline to vote in-person is 7:00 PM on Election Day.
