Colorado Voting Information

Absentee Ballot Process

All voters can receive a mail ballot before each Election Day. If you need to update the address you want you ballot mailed to, use the online tool to fill out the Voter Registration Application and update your address. You can sign up to track your mail ballot on your Secretary of State website. 

If you 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.

If you are a first time voter who registers by mail to vote in Colorado, you are required to submit one of the forms of identification (listed below) with your application. If you have not already done so, you must also submit a copy of one of these forms of identification when you return your absentee ballot application. DO NOT include original documents with the application. You must place the copy of ID in the outer envelope of the ballot, not inside the ballot itself. Please submit a copy of one of the following forms of identification:

  • A valid Colorado driver's license
  • A valid Colorado Department of Revenue ID card
  • A valid pilot's license issued by the Federal Aviation Administration
  • A valid U.S. Military ID card with a photograph
  • A valid Medicare or Medicaid card
  • A certified copy of a U.S. birth certificate
  • Certified documentation of naturalization
  • A valid U.S. passport
  • A valid student ID card with a photograph 
  • A valid identification card issued by a federally recognized tribal government certifying tribal membership
  • Valid employee identification with a photograph issued by the U.S. government, Colorado state government, or any county, municipality, board, authority, or other political subdivision of the state
  • A valid veteran identification card issued by the U.S. department of veterans affairs veterans health administration with a photograph of the eligible elector.
  • A copy of a current utility bill, bank statement, government check, paycheck, or another government document that shows your name and address. A cable bill, telephone bill or documentation from a Colorado public institution of higher education containing at least your name, date of birth, and legal residence address, or a paycheck from a government institution are also sufficient forms of ID

Note: Some forms of ID may not contain an address. If your address appears on the identification, the address must be in Colorado.

Ballots are mailed 22 days before Election Day, or three days after the County Clerk receives the request for a mail-in ballot.

To vote, fill out your ballot, sign it and return to your County Clerk.

Overseas citizens and U.S. military personnel can find information on how to register to vote and request an absentee ballot at the Overseas Vote Foundation.

Drop Boxes

Please consider returning your mailed ballot through the mail or to a county drop box if you are able. 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

Early Voting

Early voting is available and no excuse is required. Early voting is available during regular business hours for 8 days before a primary election and for 15 days before a General election.

Note: Colorado conducts elections primarily by mail. Each county clerk and recorder shall provide one or more early voting polling place(s), each of which shall be accessible to persons with disabilities. Information regarding early voting availability, locations, and schedules may be obtained by visiting your county website or by contacting your county clerk and recorder's office.

Eligibility Requirements

To be eligible to vote, you must be:

  • A U.S. Citizen
  • 16 years of age, but you must be at least 18 years old to vote in an other election
  • A Colorado resident for at least 22 days before an election
  • Not serving a sentence for a felony conviction

Incarcerated Voters & Returning Citizens: 

In Colorado, you only lose your right to vote if you are currently incarcerated for a felony conviction. If you lost your voting rights because of a conviction, you could register to vote immediately after release. Your voting rights are not restricted by pretrial detention, misdemeanors, probation, or parole. 

Voters without traditional residence: 

When registering to vote, providing a residential address is unnecessary if a voter lacks a fixed permanent address. For instance, if a voter resides permanently in an RV, they may utilize a campground as their "home base" for the purpose of voter registration. Similarly, individuals who are unable to afford regular or adequate housing can use locations such as a park, vacant lot, or homeless shelter as their "home base" for voter registration. The voter is allowed to provide any physical location as an address as long as they consider it their "home base." As for mailing addresses, post office boxes can be used. This means that if an unhoused voter selects a physical location without a specific mailing address (such as a park), they can provide a post office as their mailing address. However, it's important to note that post office boxes are never acceptable for residency purposes. 

College students that are residents of Colorado may keep their registration in their hometown and vote by mail.

ID Needed for Voter Registration

You must have a valid Social Security Number, Colorado driver’s license or Colorado ID card to register online.

If you do not have any of these forms of ID, please check the appropriate boxes on the paper registration application form. A unique identifying number will then be assigned to you by the state and you will still be registered to vote. However, if the identification section is left blank and you do not check the box(es) indicating you do not have identification, you will not be registered to vote.

Colorado now has automatic voter registration! When you interact with certain agencies, such as the DMV, you usually provide information like your name, address, date of birth, etc. This information is then used to register you to vote in Colorado. The county clerk will verify that they have the complete record to register you to vote. If your record is complete, the county clerk will send a notice to you that you are registered to vote. You can return the notice to either decline to be registered or to affiliate with a political party. If you do not decline to be registered within 20 days after the notice is mailed, and the form is not returned as undeliverable, you are then registered to vote.

For more information please contact your county clerk and recorder or contact your local League for more information.

 

ID Needed for Voting

If you are voting by mail for the first time you may need to provide a photocopy of your identification with your ballot. Voters who recently registered for the first time and are voting by mail are required to provide a photocopy of their identification.

  • A valid Colorado driver's license
  • A valid identification card issued by the Colorado Department of Revenue
  • A valid U.S. passport

  • A valid U.S. military identification card with photograph of the elector
  • A copy of a current utility bill, bank statement, government check, paycheck, or other government document that shows the name and address of the elector. A cable bill, a telephone bill, documentation from a public institution of higher education in Colorado containing at least the name, date of birth, and residence address of the student elector, or a paycheck from a government institution are also sufficient forms of identification
  • A valid Medicare or Medicaid card
  • A certified copy of a U.S. birth certificate

  • A Certificate of Degree of Indian or Alaskan Native Blood
  • Verification that a voter is a resident of a group residential facility
  • Verification that a voter is a person committed to the department of human services and confined and eligible to register and vote

A Social Security number (or last four digits) is NOT a legal form of identification for voting in person. Neither is any document produced by Colorado's statewide registration system.

Voting Machines

The voting machine systems used in Colorado are optical scan, DRE and hand-counted paper ballots.

Optical Scan: With this system, you will receive a card or sheet of paper, which you take over to a private table or booth. The card has the names of the various candidates and ballot measures printed on it. With a pen or pencil you fill in a little box or circle or the space between two arrows. When you are finished filling out all the cards, you may bring the cards over to a ballot box, where poll workers will show you how to put the cards in the box. Or in some places, you may feed the completed cards or papers into a computer device that checks your card or paper right there at the polling place to make sure you have voted the way you want to and counts the votes.

Direct Recording Electronic (DRE): This is the newest kind of system in use in the U.S. All the information about who and what you are voting for is on an electronic screen like a TV or computer screen.

There are many variations of DREs because lots of companies are inventing new ones, and many cities, counties and states are trying them out. Usually, after you have signed in, the poll workers will give you a card that you slide into a device to start your voting session.

Some of these devices will show all of the candidates and ballot choices on one big screen. Often, with these big screen devices you push a button next to the name of the candidate you want to vote for (or yes or no on a ballot measure). On other DREs, the screen is set up to show pages. On each screen or page, there will probably be one thing to vote on. For example, on one screen or page, you might vote for president. Then you might move to the next page to vote for senator. Often these small-screen devices have a touch screen, where you touch the screen next to the name of the person you want to vote for. Other devices have a key pad. Some have a keyboard, so you can write in the name of someone you want to vote for.

You let the system know you are finished voting by pushing a button, touching the screen or entering something on a keypad.

Paper Ballots: Paper ballots are one of the oldest ways of voting in America. They are still used in a few places on Election Day. When you come to the polling place, you will get a paper ballot from the poll worker. You take it to the voting booth, and use a pen or pencil to mark a box next to your candidate and issue choices. You then drop the marked ballot into a sealed ballot box.

You can learn more about voting systems by checking out the Elections Assistance Commission's (EAC) resource or through Verified Voting.
