How to Search the Grant County Jail Roster
Use the search box above to search the Grant County jail roster by name or charge. Start with the last name only — booking records don't always spell first names the way families do. If the person isn't listed, they may not be booked yet, may already be out on bond, or may be held by a neighboring county.
For the full booking record, use the official inmate search at grant-so-wi.zuercherportal.com. People sentenced to state prison are not on this roster; the Wisconsin prison system has its own inmate locator.
