Pontiac Medium Security Unit Inmate Search

Pontiac Medium Security Unit Overview

The Pontiac Medium Security Unit is listed by the Illinois Department of Corrections as a medium-security unit for adult men, with Pontiac Correctional Center as its parent institution. It shares the Pontiac campus at 700 W. Lincoln Street and is reached through the main prison's phone line. It is part of the state prison system, not the county jail.

The state opened the unit in 1937 and lists an operational capacity of 431 beds. That capacity figure counts the maximum number of beds, including health-care, crisis, restricted-housing, protective-custody, and reception beds, based on a state bed-space census. Despite that listed capacity, the unit's published population is zero in the latest data reviewed, so it should not be described as actively housing prisoners right now.

Medium Security in the State System

Security level shapes how a state prison unit operates. A medium-security unit holds sentenced men who do not need the tightest controls of a maximum-security setting, but who are still in state custody under close supervision. The main Pontiac campus is built around maximum security, with general population, segregation, protective custody, and mental-health functions, so the medium unit is a distinct designation within that larger institution.

That difference matters for a search because the security level affects housing, movement, and programming, not the lookup tool. Whether a person is medium or maximum security in the state system, the search still runs through the same statewide locator. The level tells you how a person is housed, while the locator tells you where.

Current Status of the Pontiac Medium Security Unit

This unit is an edge case among the county's detention facilities. The state lists it as an official unit with a real capacity, yet it reports no current population. Reading the state data carefully avoids a common mistake of assuming a 431-bed unit is full.

• Listed capacity - 431 operational beds, per the state facility page.
• Published population - 0 as of June 30, 2024 on the facility page.
• FY25 report - 0 population and 0 average daily population in the annual report.
• Parent institution - Pontiac Correctional Center, which holds the active population on the campus.

Because the published count is zero, any search that points to this unit should be confirmed against the live state data and the parent prison before a visit or a record claim.

The Pontiac Campus and Custody Authority

The unit sits on the same West Lincoln Street campus as Pontiac Correctional Center and the county jail. That clustering of custody sites in one part of Pontiac is part of what makes the area's inmate picture confusing. Three different facilities share a corridor, but they answer to two different governments.

The medium unit and the main prison are both state, under the Illinois Department of Corrections. The jail down the street is county, under the sheriff. A person looking for someone on this campus should always confirm which institution actually holds them, because a wrong assumption sends a phone call or a records request to the wrong agency. With the medium unit showing no population, the live state data and the parent prison are the reliable references.

Pontiac Medium Security Unit Capacity and Population

The state figures for this unit are straightforward. The facility page lists 431 operational beds and a population of zero, and the FY25 annual report repeats the zero population and a zero average daily population. These are state numbers, separate from the county jail and from the active count at the main prison.

Because the population is zero, the unit's capacity should not be added to the active prison count. Doing so would overstate how many people are actually held on the campus. The state defines operational capacity broadly, counting health-care, crisis, restricted-housing, protective-custody, and reception beds, plus beds temporarily down for repair, so the 431 figure describes the unit's full bed footprint rather than a current head count.

How to Look Up an Inmate at the Pontiac Medium Security Unit

A search for anyone tied to this unit uses the statewide corrections locator, the same Individual in Custody Search used for the main prison. The county jail line is not the right channel for a state unit, and with a zero population the live data should be the first check.

1. Open the Illinois Department of Corrections Individual in Custody Search.
2. Search by name, or by IDOC number if you have it.
3. Check the facility shown on any result, since the active campus population is at the parent prison.
4. Confirm current unit status with Pontiac Correctional Center before relying on it.

For the active prison on the same campus, see the Pontiac Correctional Center page.

Pontiac Medium Security Unit Address and Contact

The unit shares the Pontiac campus address and is reached through the parent prison's phone line. There is no separate county contact for it.

Visiting and the Pontiac Medium Security Unit

With no published population at this unit, there is no separate unit visiting schedule to rely on. State visitation rules still apply across the campus, so any visit follows the standard prison process rather than a county jail process. A visitor must be on the approved list, set by the individual, and must schedule the visit online.

Because the unit shows zero population, confirming the current location with the parent prison matters even more than usual.

Mail and Money on the Pontiac Campus

Mail and deposits for anyone in state custody on the Pontiac campus follow state rules, not county jail vendors. Mail uses the individual's name and IDOC number, and money goes through the state deposit-services system. The table sets out the basics.

Confirm the person's actual housing location first, since a name tied to the campus is held at the parent prison rather than this zero-population unit.

Records and Public Access for the Unit

Records for a state unit run through the state, not the county. The statewide locator is the public tool for current custody, and the state also offers information-release forms for a Master Record File Summary, which an attorney or the individual in custody can request. None of that goes through the county jail or the sheriff, because the unit is a state institution.

For population and capacity, the state facility page and the annual report are the sourced references, and both currently show zero people at the unit. A searcher who needs to confirm whether anyone is held here should rely on those state sources and a call to Pontiac Correctional Center rather than a county channel. Treating the unit as documented but inactive is the accurate reading of the published data.

About the Pontiac Medium Security Unit

The unit's long history reaches back to 1937, and it has been part of the Pontiac campus under the parent institution for decades. In current state data it functions as a listed unit rather than an active housing site, which is why both the facility page and the FY25 annual report show zero population.

Anyone tracking the Livingston County inmate population should treat this unit as a documented part of the campus that is not currently holding people. If the state later updates the listing, the right source for any change is the state facility page and Pontiac Correctional Center, not a county jail contact.

The unit is included here for completeness, because it appears in the state's own facility list for the campus. Listing it alongside the main prison and the county jail keeps the county's full detention picture honest, while the zero-population note keeps that picture from overstating how many people are actually held in Livingston County today.
