Chicago early voting will be available in all 50 wards. Suburban Cook County is increasing its number of sites from six to 56, and voters there may use any suburban Cook County location, regardless of where they live. Early voting sites are also opening Monday in DeKalb, DuPage, Kendall, Lake, McHenry and Will counties.

Suburban Cook County residents can register to vote at any of the county’s early-voting sites. Voters do not need to show photo identification, though election officials say it may help resolve questions about registration, an address or a signature.

Cook County Clerk Monica Gordon said her office has received more than 200,000 requests for mail ballots. The office is expanding its ability to track ballots from printing through their return, including by incorporating U.S. Postal Service scanning data.

“We know voters want confidence that their mail ballot is moving through the process, as it should,” Gordon said. The new system, called Election Lens, will also use electronic poll-book data to monitor election activity in real time across suburban Cook County.

Voters returning mail ballots can use designated drop boxes at polling locations. A drop box is also available at Soldier Field.

The expanded access gives residents additional ways to participate before Election Day. Information about polling places, voting by mail and other election details is available through the Illinois State Board of Elections website.
