Register at School or Home

Students have a decision about where to register to vote.

You have a right to register to vote at the address you consider the place where you live, whether that is your family's home or the place where you attend school. You should update your registration anytime this home address changes.

You may only be registered and vote in one location.

What Type of ID Do I Need to Register?

Colorado’s voter registration form asks for either your Colorado driver’s license or ID number, or the last four digits of your Social Security number. You must have a Colorado driver's license or ID number to register online. Be sure to provide one of these numbers if you have it.

What Type of ID Do I Need to Vote?

All voters who vote in-person need to present ID. The following are acceptable forms of ID:

  • A valid Colorado driver’s license or state identification card

  • A valid U.S. passport

  • A valid U.S. government or Colorado government employee identification card with a photograph

  • A valid student ID card with a photograph issued by a Colorado institute of higher education

  • A valid U.S. military identification card with a photograph

  • A copy of a current (within the last 60 days) utility bill, bank statement, government check, paycheck, or other government document that shows your name and address

  • A certificate of Degree of Indian or Alaskan Native Blood

  • A valid Medicare or Medicaid card

  • A certified copy of your U.S. birth certificate

  • Certified documentation of naturalization

  • A valid veteran ID card with a photograph issued by the U.S. Department of Veterans Affairs

  • A valid ID card issued by a federally recognized tribal government certifying tribal membership

  • Verification that a voter is a resident of a group residential facility

  • Written correspondence from a county sheriff indicating that a voter is confined to a county jail or detention facility

  • A valid pilot's license issued by the Federal Aviation Administration or other authorized U.S. agency

If you show ID that has an address on it, the address must be in Colorado, but it does not have to match that address associated with your voter registration.

Common Questions/Concerns

Registering to Vote Does Not Affect Your:

Federal Financial Aid

Where you register to vote will not affect federal financial aid such as Pell Grants, Perkins or Stafford loans, or your dependency status for FAFSA

Status as a Dependent on Your Parents’ Taxes

Being registered to vote at a different address from your parents does not prevent them from claiming you as a dependent on their taxes

Tuition Status

Being deemed out-of-state for tuition purposes does not prevent you from choosing to register to vote in your campus community


Will registering to vote in Colorado affect my driver’s license or car registration?

Registering to vote in Colorado may not necessarily affect your driver's license or car registration. However, as a new resident of Colorado, you may be required to make changes to your driver's license or car registration regardless of whether you register to vote there. You may wish to contact the Colorado Division of Motor Vehicles.
