Recent Arrests and/or Pre-trial Inmates in Winnebago County Jail

If you are certain your inmate is in Winnebago County Jail, or at the very least in Winnebago County County, go to this page to search for them.

If the Winnebago County Jail inmate search website is not currently online or up to date, call 815-319-6600 for assistance in locating your inmate.

The Winnebago County Jail is "open" 24-hours-a-day. When you call, give the staff member the name of who you are looking for and a birthdate or age if you have it. That person will let you know if your inmate is there.

At minimum you will need a first and last name. If you can provide the middle name or initial that is even better. In a perfect world you will also have the inmate's birthdate, but if not, an estimated age will help.

If you are not sure what county jail the inmate is located in, it helps to at least know the geographic area. Knowing what state the inmate is in is good; knowing which county is even better.

In some cases, there will be more than one possibility. Use patience and check them all. Go here to get started on a search for any jail in the state of Illinois or go to this page to begin a search for all jails in the United States.

If your inmate has been charged but not yet convicted of a misdemeanor or a felony, he or she will most likely be held in Winnebago County County within the county where the crime occurred.

If they are sent to the Winnebago County County Jail, either look them up here or call 815-319-6600 for assistance.

Recently convicted felons are sometimes held at Winnebago County County Jail until transport to a Illinois State Prison is available.

How to find an Inmate already convicted of a felony and sentenced in the state of Illinois

State Inmates

Most states have Department of Corrections websites that allow you to type in a felon's first and last name and pull up inmates in that state. Go to this page for inmates in Illinois. If you need to find an inmate in another state prison system, go here.

When you click next to the inmate's name or on a link, it will show you which jail or prison the inmate is housed in. If the inmate is no longer incarcerated, but is on parole/probation or discharged, it will tell you that as well. In addition, many state prison inmate pages show recent mug shots.

Federal Inmates

The federal prison system has its own inmate locator called the Bureau of Prisons Inmate Locator.

Type in the inmate's name and it will tell you where he or she is incarcerated and their projected release date. It also lists released federal prison inmates and the date they were released.

Federal inmates who are moved from one prison to another will show as "No longer in federal custody" on the system until they reach their next federal prison destination. This movement can take a few days to several months to complete, so keep checking back to find out where the inmate was taken.

ICE Inmates

The ICE Detainee Lookup allows friends, family members and interested parties to locate illegal and/or undocumented immigrants that are in the United States without permission.

They are held in detention centers approved by Immigration Custody and Enforcement until their hearing or date they are deported back to their home country.

To look up the detainee, users need the full legal name the person used upon their arrest and the country the person claimed they originated from. It helps to also have the "A-number", which is the number that ICE assigned to them upon their detention, which you can use instead of attempting to type the detainee's name.
