Felony Information

Under Missouri law, if you were incarcerated on a misdemeanor conviction, you may register and vote when you are released from jail or prison. If you have been convicted of a felony, you may register and vote when you have completed your imprisonment, parole, and probation. If you have committed any election offense (misdemeanor or felony), you may not vote. For more information, visit the Election Division's website, or call them at 573-751-2301.

Information for Students

  • You must be a resident of the state in which you register and vote. If you're a student from Missouri who attends school in another state, you may need to determine whether you're a Missouri resident or a resident of the state where you attend school. The important thing to keep in mind is that you may only cast your vote in one state.
  • Here's what Missouri says about residency: College students in Missouri have the option of declaring their residency from their home residence - for example, their parents' home - or from their college residence. Residency is determined by your specific circumstances, and you must intend to make Missouri your residence.
  • If you determine you're a Missouri resident, but will not be present in this state or will be away from your home district on Election Day, be sure to check the absentee ballot application requirements and deadlines. In addition, Missouri residents who attend school in-state, but in a different election district, may be eligible to register and vote in the election district where they live while attending school.
  • To determine whether you're a resident of a different state where you attend school, be sure to check that state's residency requirements.

Identification Information

Missouri says that you need to bring ONE of the following forms of identification:

  • Current identification issued by the state of Missouri, an agency of the state, or a local election authority of the state; or
  • Current identification issued by the U.S. government or agency thereof; or
  • Current identification issued by an institution of higher education, including a university, college, vocational and technical school, located within the state of Missouri; or
  • Copy of a current utility bill, bank statement, paycheck, government check or other government document that contains the name and address of the voter; or
  • Current driver's license or state identification card issued by another state
If you do not possess any of those forms of identification, you may still cast a ballot if two supervising election judges, one from each political party, attests that they know you. You may cast a provisional ballot if you are unable to present any of the acceptable forms of ID and will be counted only if you return with the proper identification before the polls close.
