The deadline to register online using a valid state ID or last 4 digits of your social security number for the 2023 Chicago Municipal Run-off Election is March 19th. You must be 18 years old by the date of the election NOT the time of registering.
In Illinois, you can still register in-person at an early polling location from March 20th through April 3rd at your assigned polling place on Election Day, or a super site. You can view all polling places, super sites, and see Early Voting Places here.
Be sure to take your ID and a piece of mail with your address along with you if you register in person. Check out the Chicago Elections website for a list of acceptable forms of ID and polling places.
If you prefer to register to vote by mail, fill out this form. The deadline to mail in this form is March 7th, 2023.
