Frequently Asked Questions about Performing an Inmate Search

What is the difference between jail and prison?

Though both types of facilities have to do with public safety, the main differences have to do with the length of confinement and who runs them. Generally speaking, jails are used to hold persons who have been arrested and are awaiting trial in court or to detain offenders who have been convicted of minor crimes. They are operated by local governments on the city or county level. Inmate Lookup provides you with an accurate list of these kinds of facilities in Illinois (see below).

Prisons, on the other hand, house offenders who have been convicted of more serious offenses and who have a projected release date farther in the future. They are typically run by the state or the federal government. Examples in Illinois include the Danville Correctional Center and the Stateville Correctional Center. Inmate Lookup walks you through the process of finding someone in a state facility at the top of this page.
