Illinois offers grace period registration, which allows you to register to vote during early voting, and even on election day prior to casting your ballot.
Online registration is the easiest, and is open from March 2, 2023 through March 19th, 2023.
If you move, you'll need to update your voter registration, which you can do in-person or online.
Register Online
Online Registration is open between March 2nd and March 19th, 2023. It reopens again on April 6th.
