Staying in touch with someone in custody? Wisconsin jails typically use third-party vendors for phone calls, tablet messaging, email, and video visits. You'll likely need to set up vendor accounts, add prepaid credits, or schedule sessions. Most non-legal calls and messages are monitored, recorded, or screened. Wisconsin is also rolling out a statewide video/tablet platform, so vendors and steps may change during the transition.

Looking for someone in Rock County, Wisconsin? Check both the county jail roster and the Wisconsin DOC Offender Locator. Each system covers different populations—one for local holds, one for state supervision—so searching both gives you the best chance of finding them. When using a public roster, search by full name or inmate ID. Confirm you've got the right person by checking details like inmate ID, name, sex, race, booking time, housing location, and classification. Keep in mind that any online listing is a snapshot, not an official record. Information can be outdated or incomplete, so note the record timestamp and verify details before relying on it.
