Illinois Detention Facility Directory

Illinois Jail Facility Directory

Search Illinois Facilities

A facility name often tells the right search route. A county jail name usually means the county roster. A correctional center, treatment center, work camp, adult transition center, or reception center usually means IDOC. FCI, MCC, or another federal label means BOP. A juvenile detention center means restricted youth-custody routing. If the facility row names more than one locality, follow the row's county subdomain and read the local serving-jail explanation.

The BOP inmate locator is the correct route for federal facilities such as MCC Chicago, FCI Greenville, FCI Marion, FCI Pekin, and FCI Thomson.

BOP facilities are physically in Illinois but remain federal custody records.

The Illinois VINELink portal can help when a county facility does not publish a live roster or when custody alerts are needed.

VINELink is a notification route, not a substitute for an official facility page or records office.

Illinois Statewide Facility List

Each covered facility link uses the county folder slug from the research and a facility-page filename. When the source county already has a known built filename, the directory follows that file. Where the apex research named a covered facility but did not expose a filename in the roll-up, the row uses the clear facility-name slug as a forward link for the county subdomain build.
