Voter service and polling centers in Denver set to open up in phased approach starting Monday

Your Personalized Voting Plan

Denver's Voter Service and Polling Centers aren't just polling locations — they're designed to solve voting problems on the spot. Need to register? Done. Got a damaged ballot in the mail? They'll replace it. Want to vote in person instead of mailing it back? Walk right in. The Central Library location at 10 W. 14th Ave. Pkwy opened June 15, with nine additional centers rolling out starting June 22.

If you're voting in person at any VSPC, bring a valid photo ID. Drop boxes, by contrast, require no ID — and Denver's Clerk says they're the most popular option in the city. The boxes run around the clock and are emptied daily by bipartisan teams of Democrats, Republicans, and unaffiliated volunteers working together.

Key Voting Deadlines — Denver Primary 2026

Here's something most Denver voters don't know: you can drop a Denver ballot into another county's drop box. Clerk Lopez confirmed that a Denver ballot dropped in a Jefferson County box before 7 p.m. on Election Day will still be counted — all Colorado counties coordinate to make sure cross-county drops get routed correctly. That means if you're near a drop box in Lakewood or Englewood, you don't have to drive back into the city.

Unaffiliated voters make up the largest voting bloc in Denver. If that's you, watch your mailbox carefully — you'll receive two ballots, one with a red stripe (Republican primary) and one with a blue stripe (Democratic primary). Choose one race to weigh in on and fill out only that ballot. Return the other unused. Submitting both will result in both being canceled.

How to Make Sure Your Vote Counts

  1. Know your registration status — Not sure if you're registered? Visit the Colorado Secretary of State's voter portal at govotecolorado.gov to check or update your registration before Election Day.
  2. Unaffiliated? Choose ONE ballot — If you receive two ballots in the mail (one red-striped, one blue-striped), fill out only one and return the other blank. Submitting both cancels them both.
  3. Find your nearest drop box or VSPC — Use Denver's online locator at denvergov.org/elections to find the closest drop box or Voter Service and Polling Center to your address.
  4. Mail ballot? Send by June 22 — The last day to mail your ballot back is June 22. After that, use a drop box or go in person — it's the safest way to guarantee it arrives on time.
  5. Bring ID for in-person voting — Any VSPC or polling location requires a valid photo ID. Drop boxes do not. Check denvergov.org for the full list of accepted IDs.
  6. Election Day final window: 7 a.m.–7 p.m. — VSPCs open at 7 a.m. on June 30. Drop boxes close at exactly 7 p.m. If you're in line at a VSPC before 7 p.m., you will be allowed to vote.

Denver Voting Resources

Denver's primary election system is built around accessibility — drop boxes in every corner of the city, VSPCs that double as voter registration offices, and a cross-county drop policy that means you don't have to go out of your way. Clerk Lopez's office has designed this to remove barriers, not add them.

But the system only works if voters know the rules. The 612 Denver residents who submitted both primary ballots last cycle didn't lose their vote out of bad intent — they just didn't know. That's exactly the kind of mistake this guide is designed to prevent. You now know more than most Denver voters heading into June 30.
