A new voter registration card was included in an election information guide mailed to all registered voters last month. Voters are not required to show the card before voting, but it does list useful information including the voter’s precinct, polling location and voting districts. Voters can also check their registration status, precinct, polling place and sample ballot at the Clerk’s website,



Election data including voter registration statistics; turnout history; and Post-Election Reports from 2014 and 2010 are available at the Clerk’s website. Maps which show where voters cast specific party ballots throughout Cook County, as well as other election data from the past four elections, can be found in the Map Room section of the Clerk’s website.

After polls close on Election Night, the Cook County Clerk’s office tabulates and displays unofficial vote totals that include: all early votes; all mail ballots received by Election Day; and all ballots cast in the precincts on Election Day. Precinct- and township-level results are not available on Election Night.

After polls close on Election Day, the Clerk’s office tabulates all mail ballots received within two weeks of Election Day if they are postmarked by March 20 and all provisional ballots that are verified. By statute, Illinois election authorities have up to three weeks to certify election results.



Many district boundaries overlap with another election jurisdiction. In those situations, election night vote totals must be combined from different websites. Here is a handy overlapping district chart to help guide your coverage.



Members of the media do not need a paper credential provided by the Clerk's office to visit, film or photograph suburban Cook County precincts. However, Election Judges will require news reporters, photographers and TV crews to show a government-issued or company identification card. Please remember interviews cannot be conducted inside the polling place.
