Cook County Clerk David Orr reminds suburban Cook County residents who are not yet registered to vote that they can still register online before the October 23 deadline.

Any voter with an Illinois driver’s license or state ID can register to vote online. Qualified applicants must be a United States citizen, at least 18 years old by the Nov. 8 election and a resident of their precinct for at least 30 days prior to the election. 

In the seven months since the March 2016 Presidential Primary Election, over 100,000 suburban Cook County residents have registered to vote online.  

Suburban Cook County voters may cast their ballots prior to Election Day by requesting a mail ballot or voting at one of the Clerk’s 52 designated Early Voting sites.

Any registered suburban Cook County voter may request a mail ballot using the online application at Applying online can take less than a minute – it is the most efficient method for voters and the Clerk’s Elections Division.

The deadline to apply for a mail ballot is November 3 – although the Clerk’s office recommends that voters request their mail ballot before October 31 to ensure against any postal delays. Ballots must be postmarked no later than Election Day, November 8, and received at the Cook County Clerk’s office within 14 days of Election Day.

Following the October 23 online registration deadline, the Clerk’s Early Voting sites will be open to all eligible suburban Cook County residents Monday, October 24 through Monday, November 7. Voters do not need to provide a reason in order to cast a ballot prior to Election Day.

Cook County residents who missed previous voter registration deadlines can still register at any of the Clerk’s county wide Early Voting sites. During this grace period, voters not yet registered must provide two forms of identification, and they must vote in person at the time that they register.
