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?

Missouri’s voter registration form asks for your Missouri driver’s license number or the last four digits of your Social Security number. Be sure to provide one of these numbers if you have it.

What Type of ID Do I Need to Vote?

Missouri requires in-person voters to present identification. IDs must be current, however, an ID that expired after the most recent general election may be used. The permitted forms of identification for voting are:

  • A Missouri driver or non-driver license;

  • A military ID, including a veteran’s ID card;

  • A United States passport; or

  • Another photo ID issued by the United States or the state of Missouri

This requirement does not apply if you are located overseas, are on active military duty or living with a family member who is, or you have a permanent disability.

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.

Does Registering to Vote Affect my Status as a Dependent on My 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.

Does Registering to Vote impact my 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 Missouri affect my driver’s license or car registration?

As a full time student in Missouri, you may be required to obtain a Missouri driver's license and update your car’s registration, regardless of whether you register to vote there. For more information, contact the Missouri Department of Motor Vehicle.
