Ballot Drop-off and Voting Locations

Traveling in October / November?

Whether you’re a snowbird who leaves Boulder County in October, a student studying abroad this fall, or will be away from home for any other reason during election season, you can still vote in the 2025 Coordinated Election. You have a few different options for getting your ballot wherever you will be located.

  1. Pick up a mail ballot early: You can pick up a mail ballot anytime Monday to Thursday* from 8 a.m. – 5 p.m. beginning Monday, Sept. 22 until Vote Centers open Monday, Oct. 27 for full voting services. Simply come in to our main office at 1750 33rd Street in Boulder.
  2. Alternative mailing address: Local/stateside ballots begin mailing Friday, Oct. 10 and ballots cannot be forwarded by the postal service. However, Boulder County Elections can mail your ballot to an alternative address. Simply update your voter registration record with an alternative mailing address. When you access your voter record, the first address is your residential address (your legal residence). If you don’t want your ballot mailed there, simply add a mailing address below this option (second address – no need to put anything in the third address area). Just remember to set a personal calendar reminder to update it after the election.

Traveling internationally?

We recommend you pick up your ballot and vote early. But if you cannot and would like to receive your ballot while traveling internationally, you can vote as an overseas voter. When updating your registration, you’ll see a question labeled, “Are you any of the following?” Select the option labeled “An overseas civilian voter who is eligible to vote in Colorado” and then follow the additional prompts about how you would like to receive your ballot. Learn more about this option on our Military and Overseas Voters page. Ballots begin mailing to overseas/military voters on Friday, Sept. 19 and continue to be mailed as registration changes are received.

*Our office is closed Fridays and will also be closed Monday, Oct. 13 for Indigenous Peoples’ Day.

Mailing Your Ballot

  • We recommend mailing your Coordinated Election ballot by Monday, Oct. 27. After Oct. 27, please use a 24-hour drop box instead.
  • Postage: You will need one first class stamp if your ballot is one page long. If your ballot has two pages, you will need two first class stamps.
