The service of the U.S. state allows applications to integrate with the Illinois Voter Registration System (IVRS). As part of the U.S. federal law, Help America Vote Act of 2002 (HAVA), it allows access to voter rolls for precincts and jurisdictions within the state along with pertinent registration information for voters, households, and areas. It provides responses to legitimate requests from political committees for voter data and houses information about ballot requests submitted by voters prior to elections.
API methods support voter search by name, address, and precinct. Methods also give access to voter signatures made at time of registration and other administrative data related to verifying voter authenticity.
