Students have a choice about where to register to vote.


Students attending college may register at their campus address or choose to remain registered or register at their permanent or home address.


You may only be registered and vote in one location.

What Type of ID Do I Need to Register?

Idaho’s online voter registration portal requires your driver’s license or state ID number. Idaho’s voter registration form asks for your Idaho driver’s license or ID number, or if you don’t have one, the last four digits of your Social Security Number. Be sure to provide one of these numbers if you have it.

If you register online at the Idaho Secretary of State Website, you will need an Idaho driver’s license or identification card.

To register on Election Day or during early voting, bring a document with your current residential address and photo identification when you go to your polling place. Students of a post-secondary education institution may use student photo identification accompanied by a current student fee statement that lists the student’s current address.

What Type of ID Do I Need to Vote?

All voters are required to present a photo identification before voting at the polls or during early voting, or sign a Personal Identification Affidavit. Acceptable identification includes:

  • An Idaho driver’s license or identification card issued by the Idaho transportation department

  • A U.S. passport or federal photo identification card

  • A tribal photo identification card

  • A current student photo identification card issued by an Idaho high school or accredited post-secondary education institution

  • An Idaho concealed carry permit

If a voter does not have the required identification, they can sign a personal identification affidavit.

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 Idaho affect my driver’s license or car registration?

As a full–time student in Idaho, you may have to make changes to your driver’s license or car registration if you are a resident of the state regardless of whether you register to vote in Idaho. For more information, you may wish to contact the Idaho Department of Motor Vehicles.
