How to Find an Inmate in Wisconsin

If someone you love was just arrested or sent to prison in Wisconsin, the first thing you need is also the hardest to get: a straight answer about where they are. Wisconsin does not have one single database that lists everyone in custody. The person you are looking for could be in a county jail, a state prison, a federal facility, or immigration detention, and each of those is searched a different way. This guide walks you through all four, in the order most families need them, and tells you what to do when someone does not show up at all.

Start here: figure out which system is holding them

Before you search anything, answer one question, because it tells you which tool to use.

How long ago were they taken into custody, and what happened? Someone who was arrested in the last few days is almost always in the county jail for the county where the arrest happened. They stay there through booking, the first court appearance, and often through their entire case if it is a local charge. People do not go to state prison when they are arrested. They go to state prison only after they have been sentenced and physically transferred into the custody of the Wisconsin Department of Corrections, which can take time after sentencing while intake happens at a reception center.

So the rule of thumb is simple. Recently arrested, case still pending, or a short sentence: look in the county jail. Sentenced to state prison time and transferred: look in the Wisconsin Department of Corrections. Federal charge: look in the federal system. Immigration hold: look in ICE custody. Most families searching for someone newly arrested waste time on the state prison site when their person is sitting in a county jail across town.

Searching the Wisconsin state prison system (DOC)

The Wisconsin Department of Corrections, or DOC, holds everyone serving a state prison sentence. Its public Offender Locator lets you look a person up by name or by their DOC number, and you can narrow the results with details like birth year, gender, or race. You have to agree to a disclaimer before the search runs. The results show the person's name, current facility, custody status, and projected release information.

To search, you generally need the person's last name, and the DOC number helps narrow it when the name is common. One thing to know: the locator covers people sentenced to state incarceration or supervision by the DOC. It does not list people held in a county or city jail, and it does not list juveniles. So if your person was just arrested and is not in the DOC results, that is expected. It means they are still in the county system below, not that they cannot be found.

Searching county jails in Wisconsin (recently arrested)

Wisconsin has 72 counties, and each county jail is run by the county sheriff. Cities also operate smaller jails for short holds. There is no statewide county jail search, so you have to find the roster for the specific county where the arrest happened.

If you know the county, search for that county's jail roster directly, or find the facility on InmateAid and use the search link on its page. Most arrests are concentrated in the populous counties: Milwaukee, Dane (Madison), Waukesha, Brown (Green Bay), and Racine. Milwaukee County alone holds roughly one in six Wisconsinites. The larger county jails post online rosters that update through the day; smaller rural counties may not post online, in which case calling the sheriff's office is the fastest route.

To search a county roster you typically need the person's full name. A booking number, if you have it, finds the record immediately. If you are not certain which county made the arrest, the city where it happened tells you: look up which county that city sits in, then search that county's jail.

Federal inmates in Wisconsin (BOP)

If the charge was federal, the person is in the custody of the federal Bureau of Prisons, not the state, and you search the BOP's own national inmate locator rather than any Wisconsin tool. It covers everyone in federal custody from 1982 to the present and searches by name or by federal register number.

Wisconsin's federal prison is FCI Oxford, a low-security facility for men with an adjacent minimum-security camp, located in central Wisconsin near the village of Oxford, about an hour north of Madison. A person arrested on a federal charge may first be held in a county jail under a federal contract, held for the US Marshals, before being assigned to a federal facility that could be FCI Oxford or a prison in another state. So if the BOP locator does not show your person yet, check the county jail where the arrest happened and call the US Marshals if you are unsure.

ICE detainees in Wisconsin

If the person is being held on an immigration matter, they are in ICE custody, which is a civil detention system separate from criminal jail and prison. ICE detainees are not criminals serving sentences; they are held while their immigration cases are decided. You search for them using the federal ICE Online Detainee Locator, which works by the detainee's A-Number (a nine-digit immigration identification number) or by their full name, country of birth, and date of birth.

Wisconsin does not have a standalone ICE detention center. Instead, ICE holds detainees inside county jails under agreements with the federal government. For years the main two were the Dodge County Detention Facility in Juneau and the Kenosha County Detention Center, and as of 2025 more counties have signed on, including jails in Brown, Ozaukee, Sauk, and Douglas counties. The Douglas County jail in Superior, in the far northwest, holds many people who were actually arrested across the border in Minnesota. People are also moved between facilities and sometimes out of state. Because of all this movement, the A-Number is the most reliable way to find someone and to keep track of them. Wisconsin also has immigration legal-aid organizations, and because these situations move quickly and have been the subject of court rulings in 2026, getting legal help early is worthwhile.

When you cannot find them anywhere

If you have searched and your person is not turning up, work through these explanations before assuming the worst.

The booking is not complete yet. Newly arrested people can take hours to appear on a jail roster, and newly sentenced people can sit in a county jail for a while before showing up in the state system. Try again later. They were released, transferred, or moved between systems. Someone can post bond, get transferred to another county, or be handed from county to federal or immigration custody, and during the handoff they may briefly appear nowhere. The name does not match the record. People are booked under legal names, middle names, maiden names, or misspellings. Try variations, and search with less information rather than more. They are a minor. Juveniles are not listed in public adult locators at all, regardless of facility.

When the online tools fail, calling works. Call the jail or facility you believe is holding them, give the full name and date of birth, and ask the booking desk or records office to confirm custody status. That is often faster than any website.

Get notified automatically: VINELink

Rather than checking rosters over and over, you can register with VINE, the free victim and family notification service Wisconsin participates in. It lets you look up a person's custody status and sign up for automatic alerts about changes such as transfer or release. It is the simplest way to stop refreshing a website every day.

Once you have found them

Finding the person is the first step. Staying connected is the next, and it matters more than most families realize for how someone gets through their time.

The best place to start is mail. Letters and photos reach almost everyone in custody, they are the most reliable form of contact, and a person who hears from home regularly does easier time. You address mail to the person at the facility holding them, with their name and DOC number. Phone calls are the next layer, and Wisconsin is reasonably affordable here. State prison calls run at a low flat rate per minute through the department's phone vendor for local, in-state, and out-of-state calls, and the federal rate caps that took effect in April 2026 hold costs down further. Many people in Wisconsin prisons now have tablets that can make calls, and some facilities provide a couple of free calls each week. A practical note: prison phones are outgoing only, so your person calls you rather than the other way around, and you set up a prepaid account first so they can reach you. County jails set their own rates and vendors. You can also send money to most facilities so your person can cover phone time, commissary, and basic needs.

To set any of this up for the specific facility holding your loved one, find that facility on InmateAid and follow the instructions on its page, since the rules, the phone carrier, and the mailing address are different at every facility. For someone held in immigration custody, remember to include the A-Number on mail and deposits.
