If you need to find out whether someone arrested in Rockford is in custody, the Winnebago County Sheriff handles that search. This page walks you through the Rockford jail roster tools and resources.
Rockford Jail Roster Quick Facts
Search the Rockford Jail Roster
The Winnebago County Sheriff's Office maintains the jail roster for Rockford and the rest of the county. The Winnebago County Jail sits at 650 W. State Street, Rockford, IL 61102. That address is just blocks from the Rockford Police Department. When someone gets arrested in Rockford, they are booked at the jail and added to the roster. Call (815) 319-6000 to reach the Winnebago County Jail. Staff can confirm if someone is in custody and share basic booking details over the phone.
For people who have been sentenced to state prison, you need a different tool. The IDOC offender search covers everyone in the Illinois state prison system. IDOC handles people convicted of felonies with sentences over one year. If someone arrested in Rockford was convicted and sent to state prison, they leave the Winnebago County jail roster. The IDOC search results show the person's name, IDOC number, date of birth, current facility, admission date, and projected discharge date. The public can call IDOC at 217-558-2200 for help with state inmate searches.
IDOC maintains a wanted fugitives list as well. This shows photos and last known addresses of people who left state custody without permission. It is a separate tool from the Rockford jail roster but can be useful if you are looking for someone who may have violated parole.
Rockford Police and the Jail Roster
The Rockford Police Department makes the arrests in the city. Their offices are at 420 W. State Street, Rockford, IL 61101. Call (815) 966-2900 to reach them. The police department handles the initial arrest, files the report, and processes the person. After that, custody transfers to the Winnebago County Sheriff. The sheriff runs the jail roster from that point forward.
People sometimes call Rockford PD looking for jail roster data. The police can tell you about an arrest. They can give you the arrest report. But they cannot give you real-time updates on custody status. That comes from Winnebago County. If you need to know whether someone arrested in Rockford is still in jail, still has a bond set, or has been released, the Winnebago County Jail at (815) 319-6000 is the right call. The two offices are close together on State Street, but they handle different parts of the process.
Note: Rockford police and the Winnebago County Jail are both on W. State Street, just a short distance apart, but they are separate agencies with different records.
Rockford Jail Roster Public Records
Under 5 ILCS 140, Section 2.15, arrest reports in Illinois must include the person's name, age, address, charges, time and place of arrest, and the arresting agency. If the person is in jail, the report must also show when they were received, discharged, or transferred. These reports must be given within 72 hours of the arrest. This law applies to all Rockford arrests and makes the jail roster a public record.
You can file a Freedom of Information Act request with the Rockford Police Department for arrest details or with the Winnebago County Sheriff for jail roster and booking records. You do not need a reason for your FOIA request. Section 7 of the law does have exemptions. Records that could compromise jail security or endanger someone may be withheld. Staff rosters and internal plans at the Winnebago County Jail are not public. But the core Rockford jail roster data, names, charges, booking dates, and bond amounts, is available in most cases.
Under 730 ILCS 5, the Unified Code of Corrections sets the rules for how inmate records are managed at the state level in Illinois. The Illinois Criminal Justice Information Authority publishes data on incarceration trends across the state. These are good resources if you need numbers beyond a single Rockford jail roster lookup.
