How the Illinois Registry Works
The Illinois State Police runs Illinois's registry. Before you search, know what the public site includes and what it legally can't show — the answer differs state to state, and Illinois's version has its own rules.

If a registrant is currently in custody, VINE tracks it and alerts you on release — the registry itself only shows the registered address.
Frequently Asked Questions
Does the Illinois website show every registrant?
Illinois runs separate public registries — sex offenders, violent offenders against youth, and murderers — searched from the same ISP portal. The national NSOPW search fills cross-state gaps.
Can I get alerts for my address?
Most state registries offer email alerts for a radius around addresses you save — school, home, workplace. Set them once and the registry watches for you.
What can I legally do with registry information?
Awareness and protection. Every state criminalizes using the registry to harass, threaten, or discriminate against a registrant — landlords and employers have separate rules to follow.
Someone on the registry lists a wrong address. Who do I tell?
The sheriff verifying that area, or the Illinois State Police directly — address verification is the compliance backbone, and tips get acted on.

The registry shows registration, not the case: Illinois court records hold the underlying conviction, the criminal records page covers full background checks, and the inmate search shows who is in custody now.
