How the Grant County Inmate Search Works
Search the Grant County roster by last name, first name or a word from the listed charge. Names may be spelled differently in booking records, so try the last name on its own first. When the public feed omits charges or bond, the official inmate search for Grant County Jail (grant-so-wi.zuercherportal.com/#/inmates) has the full booking record.
A new booking can appear several hours after the arrest, and a person transferred to another facility will drop off this list. Nearby county jails in Wisconsin, such as Forest, Green, Fond du Lac, keep separate rosters; someone arrested across a county line will be booked there instead. Milwaukee and Dane publish inmate searches.
This roster covers Grant County Jail only; it is not a statewide Wisconsin inmate search. People sentenced to state prison are listed by the state department of corrections. Sheriffs run county jails.
Posting Bail at Grant County Jail
Wisconsin cash and signature bonds appear. An Illinois bondsman in Lake County does not cover Kenosha automatically. County jail windows follow the sheriff. Bail bond agents must be licensed in Wisconsin and approved to post bonds at this jail.
Bond amounts shown on the roster can change after the first court appearance. Criminal cases from this jail are generally heard at Grant County Circuit Court. CurrentPrisonList does not accept bail payments or recommend bondsmen.
If the person also has a hold from another county or state, posting the Grant County bond may not lead to release. The jail or the defense attorney can confirm which holds are active.
