You can register and cast a ballot after the official deadline by appearing in-person at a Voter Service and Polling Center during the Early Voting period or on Election Day. Contact your Local Election Office if you have any questions.

To register in Colorado you must:

• be a citizen of the United States
• be a resident of Colorado 30 days prior to Election Day
• be 18 years old on or before Election Day
• not be confined as a prisoner or serving any part of a sentence under mandate

1. Use our Register to Vote Tool to fill out the National Voter Registration Form.
2. Sign and date your form. This is very important!
3. Mail or hand-deliver your completed form to the address we provide.
4. Make sure you register before the voter registration deadline.

All registered Colorado voters receive mail ballots. You apply for an absentee ballot if you need your ballot mailed someplace other than your usual address.

1. Use our Absentee Ballot Tool to prepare your application.
2. Sign and date the form. This is very important!
3. Return your completed application to your Local Election Office as soon as possible. We’ll provide the mailing address for you.
4. 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.
5. 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.
6. Please contact your Local Election Office if you have any further questions about the exact process.

1. Once you receive the ballot, carefully read and follow the instructions.
2. Sign and date where indicated.
3. Mail your voted ballot back to the address indicated on the return envelope.
4. Your voted ballot must arrive by the deadline or it will not be counted.

Every Colorado voter receives a ballot in the mail, but you can still vote in person at a Voter Service and Polling Center if you'd like. In-person voting voting begins at least 7 days before Election Day.

In-person voting ends on Election Day.
