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?
Idaho’s online voter registration portal requires your driver’s license or state ID number. Idaho’s paper 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.
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. Your proof of residence must be dated at least 30 days prior to Election Day.
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

Federal Financial Aid

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