The Winnebago County Jail Inmate Roster in Wisconsin is a public resource that allows anyone to check who is currently held in the county jail. WinnebagoCourt.us helps find public information about current and recently released inmates. Additionally, data can be obtained through the official website of the county sheriff's corrections division, by visiting the facility in person, or by calling the jail. A search in the roster allows you to find out the detainee's name, booking date, charges, and court status. The roster is maintained by the Corrections Division of the Winnebago County Sheriff's Office, and it is published in a PDF document format that is updated daily.
Search Current Inmates in Winnebago Jail
There are several ways to check if a specific person is currently in the county jail.
Online Search
- Visit WinnebagoCourt.us to find publicly available information about court cases and inmates.
- Go to the Current Inmate List (PDF) — this is the official list of individuals held in the Winnebago County Jail. The document is sorted by last name.
- Since the roster is in PDF format, there is no embedded search field. Use the browser's "Find on page" function (Ctrl+F or Cmd+F) and enter the person's last name.
- To check an inmate's court dates, refer to the CCAP Wisconsin Court System or call the Clerk of Courts at 920-236-4854.
What you need for the search:
- Full legal name (last name required)
- Booking number (Inmate ID), if known
Juvenile offenders are not displayed in the public roster.

The link to the Sheriff's Office homepage contains a direct link to the Jail Inmate List (PDF) in the navigation menu.
Find Winnebago Jail Booking Records Online
A booking record is created when a detained person is officially registered in the jail. This process includes fingerprinting, photographing, and entering data into the system.
Each booking record contains:
- Inmate ID (unique booking number)
- Full name of the detainee
- Gender
- Judicial status (Jud. Status)
- Date of initial booking (Initial Booking)
This data is available in the PDF list of current inmates. The document shows only those who are in custody at the time the file is generated. Once released, the person disappears from the list.
If you need older booking records or police reports, contact the Records Division of the Sheriff's Office. This division processes requests for official documents. For individuals sentenced to serve time in a state facility, use the Wisconsin Department of Corrections inmate search tool.
A state-level criminal background check can be ordered through the Wisconsin Department of Justice — data is stored in the Centralized Criminal History (CCH) database.
Search the Winnebago Jail Roster by Last Name or Booking Number
The PDF roster of the Winnebago County Jail is sorted by last name in alphabetical order. This is the primary search method.
Search by Last Name
- Open the PDF file in your browser.
- Press Ctrl+F (Windows) or Cmd+F (Mac).
- Enter the last name in full — for example, "SMITH". The roster uses uppercase letters.
- If the last name is common, add a comma and the first initials: "SMITH, JO".
Search by Booking Number
If you know the Inmate ID, enter it into the browser's search field. The number is formatted with eight digits (e.g., 22110171). This is the fastest way to find a specific person.
If the Search Yields No Results
- Check the spelling — even one incorrect letter will result in an empty outcome.
- The person may have already been released. The roster only displays current inmates.
- The detainee may not have completed the booking process yet — there is often a delay between arrest and appearance on the list.
- If the person has been transferred to a state facility, search through DOC Offender Information.
Jail Roster Updates and Search Limitations in Winnebago
The PDF file with the inmate roster is generated automatically. According to the "Run Date" label in the document, the list is updated several times a day — morning and evening generations are recorded with a few hours' difference.
However, consider the limitations:
- Delay between arrest and appearance on the list. A person who has just been brought to jail may appear in the PDF only after the next automatic update.
- Released individuals disappear. Once a person is released on bail, after serving a term, or by court decision — their name is removed from the roster. The document does not store an archive of past bookings.
- Data entry errors. Sometimes inaccuracies in name spelling occur, complicating the search.
- Adults only. Juvenile cases remain confidential according to Wisconsin law.
The roster is a snapshot of the jail's status at a specific moment in time, not a complete history of all detentions. For archival data or official document copies, contact the Records Division of the Sheriff's Office or submit a request in accordance with the Wisconsin Public Records Law.
