Voter Registration Form Instructions

The easiest way to register to vote in Colorado is online at the Secretary of State’s website. To register online, you will need a Colorado Driver’s License, Colorado State ID, or the last 4 digits of your Social Security number. Note: If you register online using the last 4 digits of your SSN, you will be asked to complete additional steps to provide us with your signature.

If you do not have one of these, you can complete a paper registration form and return it to the Boulder County Elections office via email, mail, or fax. You can type all or your responses into the PDF (except for your signature in section 7, Declaration) or you can print the form and fill everything out by hand.

If you’re a college student, be sure to check out our Student Voting Guidelines which include lots of helpful information for registering to vote in Colorado or updating your registration (in Colorado or in another state) with your college mailing address.

Voter Registration Form – Page 1

Required sections are marked with a red header and the word “Required” on the form. On this page, the labels for required sections are listed in red with “(Required)” in parenthesis.

1. Eligibility (Required) – Mark if you are a US citizen and enter birthdate (do not complete the form if you answer No to “Are you a US Citizen?”).
2. Name (Required) – Provide your current legal name. First name and last name are required, the other fields in this section are optional.
3. Identification (Required) – Enter your Colorado Driver’s License/State ID number or last four digits of your Social Security number or mark the box next to “I don’t have a CO driver’s license, ID card, or SS card.”
   • Note: If you do not provide a CO driver’s license, ID number, or SSN, you will need to provide an Acceptable ID the first time you vote.
4. The address where you currently live in Colorado (Required) – Address where you reside (no P.O. boxes).
   • If you do not have a fixed permanent address, you can still register to vote.
   • See the Secretary of State’s information for Displaced Voters for instructions.
   • You will need to list an address you regularly return to as your residential address and also provide a valid mailing address, see information for section 5 below.
5. The address where you currently receive mail – Complete this line if your mailing address is different from your voter registration address (where you live). If you are a displaced voter, you can provide a friend/relative’s address, P.O. Box, homeless shelter, etc. as long as it is a valid mailing address.
6. The address where you want to receive your ballot – Complete this line if you need your ballot sent to a different address than your residential/mailing address (for example, if you will be traveling during the next election). If you include a temporary address, be sure to change it after the election.
7. Declaration (Required) – Read the self-affirmation then sign and date. If you are unable to sign, see section 11 below for information on having someone witness you making a mark.

8. Political affiliation – If you wish to vote in primary elections, you must either select a party affiliation or register as Unaffiliated. In Colorado, voters can participate in primaries if they are registered as Democrat, Republican, or Unaffiliated (unless another party also holds a primary, which is rare).
9. Information about you – While optional, it is highly recommended that you provide an email address. It helps us get in touch with you if there is ever an issue with your ballot, such as a missing signature. You will also receive important election updates and reminders (but we will never spam or share your email address).
10. Updating your record? – Only complete this if you are updating an existing voter registration record.
11. Witness signature – If you are unable to sign this form, please have a witness sign and date here, affirming that they witnessed you make your mark on section 7.
