A jail roster is a custody record, not a court docket. Charges listed at booking are allegations, not convictions. Custody status, bond and release details change constantly, so confirm anything time-sensitive with Jefferson County Jail or the court. Official source: Jefferson County Sheriff's Office. If a record on this page is inaccurate, use our corrections and removal page.

Jefferson County Jail: address, phone and visiting

Call before you travel. Visitation at Jefferson County Jail is normally scheduled in advance and may be video-only, bonding hours can be shorter than the lobby's opening hours, and both change without much notice. The desk can also confirm whether someone booked in the last few hours is in custody, which a roster sync cannot do.

The federal facility dataset lists Jefferson County Jail with 229 beds as recorded in 2018, while 161 people appear on the roster published today. Read those two numbers side by side rather than as an occupancy rate: rated capacity is not a live figure, jails open and close housing units, and a roster counts everyone booked into the facility including people being held for other agencies.

Facility details from the DHS HIFLD Prison Boundaries dataset, last recorded 2018-05-09. We publish them as-is and do not independently verify them; if something here is wrong, tell us and we will correct it.

What to do with this information

Posting bond in Jefferson County

Bond is set by a judge, usually at a first appearance within about 24 to 72 hours of booking. Until a bond amount is set, no one can be released. Once it is set you generally have two options: pay the full amount in cash directly to the detention center, which is refundable at the end of the case, or pay a licensed Wisconsin bail bondsman a non-refundable fee, typically around ten percent, to post the bond for you. Ask the jail which payment methods it accepts and whether bonding hours are limited.

Sending money to someone in custody

Most county jails use a third-party commissary vendor rather than accepting cash at the desk. You will normally need the person's full legal name and booking number, both shown on the roster above. Funds usually appear on the account within a few hours and are used for commissary, phone credit and messaging. Vendor fees vary, so check the amount charged before confirming a deposit.

Phone calls, mail and visitation

Calls are placed by the person in custody, not by you, and are recorded. Visitation is often scheduled in advance and may be video-only. Physical mail is inspected, and many facilities reject anything other than plain letters on white paper. These rules differ from county to county and change often, so verify them with Jefferson County Jail before making arrangements.

Finding the related Jefferson County court case

The roster shows custody, not court proceedings. To follow the case itself, including hearing dates, filings and final disposition, you need the Wisconsin court record system for Jefferson County. Search using the person's full legal name and, where possible, date of birth or case number.

If the person is not on the roster

They may have been released, transferred to another facility, held by a different agency, or booked too recently to appear in the latest sync. People serving longer sentences are usually held by the state department of corrections rather than a county jail, and appear in a separate state system.
