Colorado ballots are due by 7:00 PM on Election Day. For the 2025 Coordinated Election, that deadline is 7:00 PM on Tuesday, November 4, 2025. If you’re voting by mail, be sure your ballot is received by the county election office by that time; some counties recommend mailing early or using in-person drop boxes to ensure timely receipt. If you plan to vote in person, you’ll need to be in line by 7:00 PM on Election Day. Key tips:

• Ballots are mailed to all active registered voters in Colorado for coordinated elections, with return deadlines typically aligned to Election Day. Check your county’s specific instructions if your address or eligibility has recently changed.
• If you need to verify your registration, find your polling location or ballot drop-off options, or confirm ballot return methods, contact your county clerk and recorder or visit your county’s election office website.
• For military or overseas voters (UOCAVA), there are separate timelines and mailing options; confirm deadlines with your local election official.
