Election Info

ELECTION DAY IS TUESDAY, NOVEMBER 4, 2025

ALL COLORADO ELECTIONS ARE MAIL-IN BALLOT. The Boulder County Clerk will mail ballots to voters beginning October 10 (You can sign up for Ballot Track to receive a text when your ballot is on its way to you.) 

The Boulder County Clerk will have ballot content posted on bouldercounty.gov at the end of September. 

The last day to register or update your registration and still receive a ballot in the mail will be announced by the Boulder County Clerk on their website. Closer to the election, if that deadline has passed, simply visit a Vote Center in person to register, vote, or request a replacement ballot.

In Colorado, there is no registration deadline. Voters can register and vote on the same day at any Vote Center.

BALLOTS MUST BE RECEIVED NO LATER THAN 7PM, ELECTION DAY, NOVEMBER 4, 2025. (Fill out your ballot, and be sure to sign your envelope — do not sign your ballot!) You can return your ballot to any 24-hour ballot drop box in Boulder County (see list of locations included with your ballot) or by mail. If returning your ballot by mail, the last recommended day to mail will be announced by the Boulder County Clerk at a later date. Postmarks do not count.
