How do I get my ballot?

Every voter in Colorado receives a mail ballot. Your mail ballot will be sent to the mailing address you provided when you registered to vote. To check what address you provided when registering to vote, please visit www.GoVoteColorado.gov.

All Colorado voters receive mail ballots. Eligible voters with a disability may request to access their ballot and vote their ballot electronically. An eligible voter must print the voted ballot, the accessible ballot application, and sign the accessible ballot application. All of these materials must be returned together and returned through the USPS or in-person at a county drop-box or county VSPC. For your mail ballot to be counted, it must be received by the county clerk's office no later than 7:00 PM on Election Day. If you did not mail your ballot in with enough time to meet the deadline, you MUST deliver it to your county clerk's office by 7:00 PM on Election Day.

If you wish to vote in-person, you may do so at a voter service and polling center. To find your local polling locations, please visit www.GoVoteColorado.gov.

How do I know if my mail ballot has been mailed to me?

First, go to www.GoVoteColorado.gov. You can then log into your voter record. Once you are logged into your voter record, it should show you whether your mail ballot has been sent. If you run into any snags or have questions about the status of your mail ballot, please contact your local county clerk and recorder.

What is a "residence" for purposes of voter registration and voting?

The term "residence" generally means the principal or primary home or place in which a person lives. A "residence" is a permanent building or part of a building and may include a house, apartment, condominium, room in a house, or mobile home.

Homeless voters can register to vote. A homeless voter may use any address within a specific county that he/she regularly returns to and has the intent to remain. This may include a homeless shelter, a homeless service provider, a park, a campground, a vacant lot, a business address, or any other physical location.

You must have a residence to register to vote. Once you establish a residence, it exists until you establish a new residence.

Note: you may not have more than one residence.

If I choose not to vote on a candidate or question, will my other votes still be counted?

Yes. If you choose not to vote for a candidate or a ballot question, the rest of the votes on your ballot will be counted.

How do I make sure my mail ballot will be counted?

Every valid mail ballot is counted. To be sure your ballot is valid, follow the instructions on the mail ballot envelope. This includes making sure your ballot is signed when it is returned.

For your ballot to count, your county clerk must receive your ballot no later than 7:00 PM on Election Day. If you are unsure whether your ballot will arrive through the mail on time, drop it off in-person at either a drop-box or a drop-off location. There are drop-box and drop-off sites located throughout your county. Drop box locations are open 24 hours per day. If you have trouble finding a drop-box or drop-off location, contact your county clerk and recorder.

If you are registering to vote for the first time, you may need to provide a copy of your ID with your mail ballot. These instructions will be provided by your county clerk with your mail ballot.
