The Fond du Lac County jail roster is a publicly available record of individuals currently held at the county jail in Wisconsin. FondduLacCourt.us can help you find publicly available information about current and recent inmates, including booking details and charges. You can also access jail roster information through the Fond du Lac County Sheriff's Office inmate roster, by calling the jail directly, or by visiting in person. The roster allows the public to look up who is currently in custody, view the charges against them, and confirm detention status. Maintained by the Fond du Lac County Sheriff's Office, the online roster is updated multiple times per day and hosted on the sheriff's department website.

Find Fond du Lac Jail Booking Records Online
A booking record is created each time an individual is processed into the Fond du Lac County Jail. During booking, jail staff record key information that becomes part of the public record:
- Booking number — a unique identifier assigned to that specific intake
- Date and time of booking
- Charges — the criminal offenses listed at the time of arrest
- Arresting agency — the law enforcement department that made the arrest (e.g., Fond du Lac Police Department, Sheriff's Office, Wisconsin State Patrol)
- Custody status — such as pre-trial detainee or sentenced
The most straightforward way to access current booking records is through the sheriff's office inmate roster. This online roster lists individuals who are currently in custody along with their status.
If you need booking records that are no longer displayed on the roster — for example, for someone who has already been released — you can submit a public records request to the Fond du Lac County Sheriff's Office. Under Wisconsin's Public Records Law, most booking records are accessible to the public, though certain information may be redacted to protect ongoing investigations or victim identities.
For criminal background check purposes beyond a single booking, the Wisconsin Online Record Check System (WORCS) through the Department of Justice provides a statewide criminal history search.
Search the Fond du Lac Jail Roster by Last Name or Booking Number
The Fond du Lac County inmate roster supports two primary ways to locate someone:
Search by Last Name
- The roster lists inmates alphabetically. Browse through the paginated entries to find a specific last name.
- Use your browser's find function (Ctrl+F or Cmd+F) to quickly locate a name on the page you are viewing.
- Make sure you are using the individual's legal name — nicknames or aliases may not appear.
- Double-check spelling. A single incorrect letter can cause you to miss a result.
Search by Booking Number
- If you have a booking number from a prior interaction with the jail or from court documents, you may be able to use it to locate the specific record.
- Booking numbers are unique to each intake, so this method returns a single, precise result when available.
If Your Search Returns No Results
There are several reasons an inmate may not appear on the roster:
- The person may have already been released or transferred.
- Booking may still be in progress — there is sometimes a delay between arrest and the record appearing online.
- The name may be spelled differently than expected (check for alternate spellings or hyphenated names).
- The person may be held at a different facility or under state custody through the Wisconsin Department of Corrections.
If you still cannot find someone, call the jail at (920) 929-3390 and ask staff to verify whether the individual is in custody.
Jail Roster Updates and Search Limitations in Fond du Lac
The Fond du Lac County inmate roster is updated multiple times per day. Based on timestamps displayed on the roster page, data loads occur at regular intervals throughout the day — typically several times between early morning and afternoon.
What This Means in Practice
- Someone arrested in the middle of the night may not appear on the roster until the next scheduled data load.
- An inmate who is released, bonded out, or transferred may still appear on the roster briefly until the next update cycle.
- The roster reflects current custody only. Once a person is no longer held at the jail, their record is removed from the online list.
Known Limitations
| Limitation | Details |
|---|---|
| Not an archive | The roster does not store historical bookings. It shows only individuals currently in custody. |
| Data entry delays | There may be a gap between when someone is physically booked and when their record appears online. |
| No juvenile records | Individuals under 18 are excluded from the public roster. |
| Sealed or restricted cases | Certain records may be withheld if they involve protected information or active investigations. |
For court case details tied to a specific booking, use the Wisconsin circuit court case search to look up filings, hearing dates, and case dispositions.
