List of Registered Voters / Voting History

Voter registration and voting history data are public records available for inspection. Units of government or political committees, who are registered with the State Board of Elections, may purchase voter registration lists and associated voter history in electronic form for bona fide political purposes. The Illinois State Board of Election prohibits the use of electronic file for commercial solicitation or other business purposes. (Chapter 10 ILCS 5/4-8, 5-7, and 6-35, Illinois Compiled Statutes)

Voter information is governed by the Illinois Compiled Statutes (Chapter 10 ILCS 5/4-8, 5-7, and 6-35):

  • Political committees, who registered pursuant to the Illinois Campaign Finance Act or the Federal Campaign Act, are qualified to receive this data.
  • Data can only be used for bona fide political purposes.
  • Data shall not be used under any circumstances by political committees or individuals for purposes of commercial solicitation or other business purposes.
  • Voter information contained on compact disk may not be released to another individual, group, or political committee without prior approval of the State Board of Elections.
  • Units of Government are qualified to receive this data but may not use the information for political purposes.
