  • Where can I find access to criminal records?
    Access to criminal records varies by state and the type of record sought. In Illinois, the Illinois State Police (ISP) maintains the state's central repository for criminal history records. While arrest records may be reported in news sources, they do not always appear in criminal history searches unless there is a conviction. Individuals can access certain criminal history information, but it is limited. Illinois law allows public access to criminal histories of convictions, which can be obtained through the ISP. There are two methods for accessing this information: fingerprint-based searches and non-fingerprint searches. Fingerprint searches tend to be more reliable, as they provide accurate identification compared to name-based searches. For more information on how to request criminal records in Illinois, you can visit the Illinois State Police website at https://isp.illinois.gov/.
