Who is eligible

To register in Denver you must be a United States citizen, at least 18 years old by election day, and a resident of Colorado and the City and County of Denver at the time you register. If you are registering for a specific election, you must meet any state registration deadline listed below.

How to register

  • Online: Use the Colorado Secretary of State online registration tool; follow the prompts to sign in or create an account and submit your application. Register online[2]
  • By mail: Complete a paper Voter Registration Application (available from state or county election offices) and mail it to the Denver Elections Division address found on the official city site.[1]
  • In person: Register or update your registration at the Denver Elections Division office during business hours or at designated voter service centers.
  • At DMV: When you apply for or renew a Colorado driver license or ID, you can register to vote or update your address through DMV services.
  • Fees: There is no fee to register to vote.

Residency rules — what counts as a residence

Residency for voter registration generally means your domicile: the place you intend to return to after any absence and where you live most of the time. P.O. boxes alone do not establish residence for registration; a street address or valid physical description is required where asked. If you move within Denver, update your address promptly to ensure you receive ballots and are eligible in the correct precinct.

Penalties & Enforcement

Enforcement of voter registration and residency requirements is handled by the Denver Elections Division and the Colorado Secretary of State when statewide matters apply. Specific civil fines or criminal penalties for fraudulent registration are governed by state law; the cited official pages do not specify dollar amounts for fines or the full escalation scheme on the city registration pages and state registration summary pages. See the official contacts below to report suspected violations or request enforcement information.[1][2]

Intentional false registration can lead to cancellation of registration and referral to state authorities.

Escalation and sanctions

  • Initial administrative actions: cancellation or correction of registration (not specified on the cited page).
  • Referral to state enforcement or prosecutor for alleged criminal acts (specific penalties not specified on the cited page).
  • Non-monetary remedies: removal from rolls, provisional ballot processes, or notation of challenge.

Appeals, reviews, and time limits

If your registration is challenged or cancelled you may have rights to provide proof of residency, file an administrative appeal, or seek review under Colorado election procedures; the city and state pages direct you to official contact offices for timelines and appeal steps.[1]

Applications & Forms

The primary official forms and methods are:

  • Colorado online voter registration form via the Secretary of State (official online application). Colorado SOS voter registration[2]
  • Paper Voter Registration Application available from county election offices; mail or deliver to the Denver Elections Division (contact details on the city site). [1]

Common violations

  • Registering at an address where you are not domiciled.
  • Registering more than once in different jurisdictions.
  • Failing to update your address after moving within Denver.
