"I registered in high school or somewhere else; do I need to reregister?" In the state of Illinois, you only need to re-register if you change your address, change your name, or haven't voted for several elections. So you do not need to register each time there is an election unless you've moved, had a name change, or haven't voted in a while. If you can't remember if you registered to vote or not, click here: Am I registered to vote in Illinois?

Special Circumstances for Students

"Should I register to vote with my home address or my school address?"

By law, you may register with either (but not both), and there are advantages and disadvantages to either option.

Consider the following if you register with your school address:

  • You will be able to vote here on Election Day (nearly always on a Tuesday).
  • You will not be able to vote in your local elections (e.g. city mayor, your U.S. Representative)
  • You will need to reregister when you finish school and move (but you would have to do that if you move from your parents'/home address as well)

Consider the following if you register with your home address:

  • You will have to get home on Election Day to vote (nearly always on a Tuesday), or you will have to vote early or vote by absentee ballot before the election.
  • You will be able to vote in your local elections.

Am I Registered to Vote?
