Tuesday is the last day of regular voter registration in Illinois before the March 15 primary election.
Illinoisans with a state drivers' license or an ID issued by the secretary of state's office can register to vote online at the State Board of Elections' website until regular registration closes.
Illinois residents can check if they are registered to vote here.
State residents looking to register or change their voting address after February 16 can do so during a registration "grace period" that runs through election day on March 15. During the grace period, residents may register in person at the office of their election authority. Two pieces of identification, one of which has to include a current address, is required to register in person during the grace period.
In Illinois, 17-year-olds who will turn 18 by the November 8 general election can participate in the March 15 primary election.
