This website is a private reference guide, not a Marathon County office. We cannot confirm whether someone is in custody, release a person, post bond, schedule a visit, or retrieve an official booking record. Use the appropriate government office or official portal for those tasks.
Where to Start
For adult jail custody, the main local contact is the Marathon County Sheriff's Office and its Corrections Division at the courthouse in Wausau. The research file did not publish public counter hours for every office, so call before going in person.
Marathon County Sheriff's Office500 Forest Street
Wausau, WI 54403
Main phone: 715-261-1200
Jail/Corrections: 715-261-1700
Public-records requests for sheriff, jail, booking, police-report, or older record material can be filed through Marathon County's NextRequest portal: https://marathoncountywi.nextrequest.com/requests/new.
For filed court records, contact the Marathon County Clerk of Courts at 715-261-1300 or use Wisconsin Circuit Court Access. For prosecution questions, the Marathon County District Attorney's Office is listed at 715-261-1111. Use these routes based on what you are trying to find:
- For someone currently held or supervised by the county jail, start with jail inmate records and the jail line at 715-261-1700.
- For public booking photos and photo-request limits, use jail roster mugshots and, when needed, the NextRequest public-records form.
- For charges filed after an arrest, use court records after a jail arrest, the Clerk of Courts, and Wisconsin Circuit Court Access.
- For facility-specific address or visit information, use the Marathon County Jail and Marathon Juvenile Detention Facility pages listed in the footer.
- For a sentenced Wisconsin prisoner, search the Wisconsin Department of Corrections Offender Locator at https://appsdoc.wi.gov/lop/welcome.
- For a federal prisoner or immigration detainee, use the Bureau of Prisons locator or ICE Online Detainee Locator System rather than the Marathon County jail roster.
