Computerized Registration Data

Computerized Voting Data
The State Board of Elections compiles a database of voter registration information provided by the 109 Illinois election jurisdictions. Illinois counties (and 7 cities) submit data to the Board electronically on a regular basis, usually nightly.

Voter data is available to registered political committees for bonafide political purposes. Use for commercial solicitation or other business purposes is prohibited. (Chapter 10 ILCS 5/4-8, 5-7, and 6-35, Illinois Compiled Statutes).

Files of computerized voter registration data are available on DVD or CD-ROM. The Board offers two file formats that are tailored to the information needs and processing capabilities of those requesting voter data. (Date of Birth is no longer provided.)

Please note: The Board provides files of voter data; the Board does not provide software to process voter data.

Entire state $500
Supreme/Appellate District $100
Cook County $100
