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 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. 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.

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

Note: You must have a residence in order to register to vote. Once you have established a residence, it exists until you establish a new residence. Residency for the purpose of voting means the principal or primary home place in which you live. 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 provided, a park, a campground, a vacant lot, a business address, or any other physical location. College students that are residents of Colorado may keep their registration in their hometown and vote by mail.

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.

All voters can receive their ballot through the mail as long as they are registered to vote before 8 days before the election. Some voters with a disability may request to access their ballot and vote electronically. For more information about receiving and voting your ballot please contact the Secretary of State. Under HAVA, each polling place must contain a voting system that is accessible for individuals with disabilities, including for visually impaired voters, in a manner that provides the same opportunity for accessibility and participation (including privacy and independence) as for other voters. For more information, you can utilize the American Association of People With Disabilities (AAPD) resource.

Employers must grant employees two hours of paid leave to vote, unless polls are open three hours before or after regular working shift.

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.
