Types of Correctional Facilities in Illinois

Those who are serving their sentence in an Illinois state prison are overseen by the Illinois Department of Corrections (IDOC). The IDOC has a centralized inmate database that makes it easy to search for inmates in federal prison.

However, if an inmate is serving their time in a county jail, police jail, or a city jail, you will have to visit those sites to find information.

Below you will find information on how to do an inmate search. From there, you will be able to send money and contact an offender.

Illinois Department of Corrections Mission

Every prison throughout the states has a mission. The mission of the Illinois Department of Corrections is to protect the public from those who break the law through a system of incarceration, supervision, and programs to enhance successful reentry into society.

How to Do an Inmate Search

If you would like to talk to an inmate, send money, or visit, you will need to first do an inmate search to get the information you need. You can easily do an inmate search online using the IDOC website.
