McHenry County Jail Inmate Search
McHenry County Jail Inmate Lookup
Most local arrests end up at the McHenry County Jail, 2200 North Seminary Avenue, (aka Route 47), Woodstock, IL 60098 (815-338-9396). Search the inmate search first. VINELink tracks custody and sends alerts when the Sheriff's Office books someone. Booking at the county jail can lag; a Boone County jail may have the person. Call 815-334-4700. The sections below run from the county jail to state and federal custody.
How do I search for an inmate?
- Start at the inmate search with the person's name.
- Use VINELink, or the VINELink app for iPhone or the VINELink app for Android.
- No result: phone the McHenry County Sheriff's Office, 815-334-4700.
Where is a federal defendant from McHenry County held?
The U.S. Marshals Service may hold federal defendants in county jails in this county. The Northern District of Illinois hears it at Stanley J. Roszkowski U.S. Courthouse, 327 S. Church Street, Rockford, IL 61101 (815-987-4355). Use VINELink before sentencing; the Federal Bureau of Prisons inmate locator after.
↑ Back to the question listWhat about youth arrested in this county?
Youth stay off the roster (705 ILCS 405/1-7). A judge here picks the juvenile detention center for detained youth. Call 815-334-4700 to learn about a detained child's hearing.
↑ Back to the question listHow does release work after an arrest?
Illinois ended cash bail in 2023 under the Pretrial Fairness Act, so there's no money to post in McHenry County (725 ILCS 5/110). Within 48 hours, a judge rules on release (725 ILCS 5/109-1). Full details: our bail guide.
