Information for New Voters

How to Vote in Boulder County

To be eligible to vote in Colorado, you must be:

A U.S. citizen

At least 18-years-old by the time of the election*

A resident of Colorado for at least 22 days before the election

Must not be serving a sentence of confinement or detention for a felony conviction (Note: Those on probation or parole ARE ELIGIBLE to vote.)

*17-year-olds can vote in primary elections if they will turn 18 by the time of the following general election. Additionally, 16 and 17-year-olds are encouraged to pre-register to vote. This means that they will automatically be mailed a ballot when they become eligible to vote in an election.

ID Requirements

You do not need an acceptable form of ID in order to register to vote, but you must produce this documentation the first time you vote. Therefore, it is recommended to provide this documentation during the registration process to avoid needing to mail in a form of identification when you vote. See the Secretary of State’s list of Acceptable Forms of Identification.

Online

The easiest way to register to vote is online at www.GoVoteColorado.gov. To register online, you will need a Colorado Driver’s License or Colorado State ID. Be sure to include an email address in order to receive important voting and elections updates from our office (we only email a few times during each election and will never spam or sell your email). Including an email address also helps us get in touch with you if there is ever an issue with your ballot. College Students: Please see our Student Voting Guidelines.

By Mail / Email / Fax

If you do not have a Colorado Driver’s License or State ID, you may register using the paper voter registration form (English Form; Forma Español). Print the form, complete it (see instructions below), and return it to the Elections Division:

  • By Email: Scan and email the completed form to Vote@BoulderCountyVotes.org
  • By Mail: Boulder County Elections, 1750 33rd Street, Suite 200, Boulder, CO 80301
  • By Fax: 303-413-7728
Instructions for completing a voter registration form

In-Person

If you prefer, you may also register in-person year-round at any of our three Boulder County Clerk & Recorder offices, open 8 a.m. – 4:30 p.m.

  • Boulder: 1750 33rd Street
  • Longmont: 529 Coffman Street
  • Lafayette: 1376 Miners Drive

During election periods, eligible residents may also register to vote at any Vote Center.

In Colorado, all active, eligible voters are mailed a ballot for each election.

  1. Follow the instructions included in your mail ballot packet. Ballot Return Envelope
  2. Your packet will include a return envelope with your name pre-printed on it. When you are finished marking your ballot, place it in your own return envelope. Be careful not to switch envelopes with anyone else in your household.
  3. If your return envelope is purple, you must include a photocopy of an Acceptable Form of ID.
  4. Finally, be sure to sign the envelope. Your signature is required to verify your identity and is what makes your vote count. (You do not need a “witness signature” unless you are unable to sign for yourself.)

If you prefer to vote in-person, you may also visit a Vote Center to register and vote up to and including Election Day. If you vote in-person, you will be required to show current and valid ID.

All ballots must be returned by 7pm on Election Day to be counted. You have three options for returning your completed ballot:

24-hour ballot drop box24hr Ballot Box

This is the preferred option, as it eliminates any risk of your ballot getting lost or delayed in the mail. We have over a dozen dropbox locations throughout Boulder County. Find locations in your mail ballot packet or on our Ballot Drop-off Locations page.

Return by USPS Mail

You will need to provide postage (look for required amount specified in voter instructions). Please allow plenty of time for your ballot to arrive. It is recommended that you mail your ballot at least 8 days before Election Day. It is too late to return your 2020 General Election ballot by mail. Please use a 24-hour ballot drop box instead. Your ballot must be received by our office by 7pm on Election Day (postmarks do not count).

Return to a Vote Center

You may also drop off your mail ballot during Vote Center hours. This option is not recommended during the COVID-19 pandemic.

Tips for New Voters

  • Sign up for Ballot Track, a free service that helps you keep tabs on the status of your ballot.
  • Include an email address in your voter registration so we can easily get in touch with you if there is ever an issue with your ballot. You will also receive important elections updates & reminders from our office (we do not spam or sell our lists). You can also sign up for emails here.
  • Ballots are mailed to voters starting about three weeks before each election. Check your mail regularly around this time. If your ballot does not arrive within a week, contact our office to request a replacement.
  • Check your voter registration online before each election to make sure it’s up-to-date. It is very important that you update your address whenever you move, since ballots do not get forwarded.
