Winnebago County Jail Overview

Winnebago County Jail is operated by the Winnebago County Sheriff's Office. The public jail address is 4311 Jackson Street, Oshkosh, WI 54901. The jail information line is 920-236-7380, and the sheriff's main non-emergency numbers are 920-236-7300 and 920-727-2888. The research names Sheriff John Matz as the current sheriff and Amber Rozek as Corrections Captain in the sheriff directory.

The jail holds the local Winnebago County jail population. That includes people booked after arrest, pretrial detainees, sentenced county-jail inmates, probation or revocation holds, hold/detain cases, and people connected to electronic sanctions, GPS, Huber, or work-release status. It does not hold every person with a Winnebago County court case. Once a person is sentenced to state prison and transferred, the Wisconsin DOC locator becomes the correct search tool.

Winnebago County Jail Roster Lookup

The official county jail lookup starts at the Winnebago County Corrections Division page. The roster itself is the current inmate list PDF. It is sorted by name in the inspected run and shows InmateID, name, sex, judicial status, and initial booking. Use the PDF viewer's search function because the county source does not provide a separate search form.

1. Open the current inmate list from the sheriff Corrections page.
2. Check the run date so the result is not treated as real-time when it is only the latest posted PDF.
3. Search the PDF by last name or a distinctive spelling fragment.
4. Confirm identity with the InmateID, sex, and initial booking date.
5. Open the jail media blotter when charge, arresting agency, or recent release detail is needed.
6. Call the jail information line if the person may have been booked, released, or transferred after the PDF run.

The roster does not display mugshots, bond, housing unit, or court dates in the captured research. Court-date questions go to the Clerk of Courts or WCCA. Booking-photo requests, when appropriate, go through the records custodian rather than a public mugshot gallery.

Winnebago County Jail Contact

The jail and sheriff office share the Jackson Street public location. The sheriff FAQ and Records Division pages describe regular office hours as Monday through Friday, 8 a.m. to 4 p.m. The Property Records Window is also described as regularly staffed during those weekday hours, with closed windows during certain overnight and meal periods when staffed outside regular hours.

If the front doors are locked, the county source instructs visitors to press the entrance button to call Master Control. Visitor parking details and public transit routes were not located in the official county source, so verify travel details before arrival.

Winnebago County Jail Visitation

Winnebago County Jail social visitation is video-only in the captured county FAQ. Visits must be scheduled through GettingOut. The inmate is responsible for setting up the visitor list and scheduling visits after classification. Jail staff does not pass messages to inmates and does not release visiting information by phone because of privacy for the inmate and visitor.

Do not go to the jail lobby for a social visit unless the jail has specifically directed that visit. The county source did not publish a standard in-person social visit schedule.

Winnebago County Jail Mail and Money

Mail and commissary rules are specific. Regular inmate mail uses a Phoenix, Maryland processing address. Legal mail and packages use the jail's Jackson Street address. The sender's full name and return address must appear on the envelope. Stamps, blank envelopes, and blank paper are treated as contraband and are not delivered. Books and magazines must come from a bookstore or publisher, and hardcover books are not allowed.

Winnebago County Jail Bond

Bond is handled in person at the jail. The county says bond payments cannot be made online or by phone. A valid photo ID is required. Accepted forms are cashier's checks, exact-change cash, and credit or debit cards. Credit and debit payments carry an 8.5% PayGOV.us convenience fee, and the cardholder must be physically present. Money orders are not accepted for bonds or fines.

A no-bond hold, probation hold, revocation hold, detainer, or court order may prevent release even when a person appears in the jail population. Confirm release terms with jail or court staff before traveling.

Winnebago County Jail Records Requests

The Sheriff's Records Division is the records channel for sheriff-held reports and official documents. The county directs users to the NextRequest portal for efficient public-records requests. The portal is available 24 hours a day, but it can provide only records for which the Sheriff's Office is the custodian.

The Sheriff's Office directory lists inmate information, property records, warrants, corrections leadership, and other staff contacts. Use that directory when the question is a jail operation question. Use WCCA or the Clerk of Courts when the question is a filed charge, court date, judgment, or copy of a court document.

The directory is also useful because Winnebago County, Wisconsin is often confused with Winnebago County, Illinois or Iowa in search results. Oshkosh and Jackson Street are the Wisconsin signals.

Winnebago County Jail Programs

The research captured work release, Huber/GPS or electronic monitoring setup materials, video visitation, commissary, phone access, and mail rules. The Work Release Unit must be contacted by people sentenced to jail and instructed to report within 72 hours. The contact number is 920-232-1919, Monday through Friday, 8 a.m. to 3:30 p.m. The county also links an Electronic Monitoring setup packet and tells users to complete all fields before reporting.

Formal county jail program details for education, GED, treatment, religious services, grievance procedure, medical screening, mental-health screening, accreditation, and capacity were not located in the captured county source. Those topics should not be overstated. For specialized treatment or state prison programs in Winnebago County, use the DOC facility pages and the Wisconsin Resource Center page instead of assuming county jail services.
