Statewide rules that apply at every Illinois state prison

These rules are set by Illinois DOC and apply at every unit. The full list — including all permitted and prohibited items and the approval process — is in Visiting in Illinois.

Dress code

Clothing must be in good taste — nothing gang-related, sexually explicit, or offensive, and nothing that resembles what incarcerated people or staff wear.
Each prison sets its own visiting dress and item rules, so confirm the specific facility's rules before traveling, since a visitor who is dressed out of code can be turned away.

ID: Every visitor must be on the incarcerated person's approved visitor list, which the person arranges from inside — staff cannot tell you whether you are on a list. Adult visitors bring two forms of identification, one a state-issued photo ID, along with vehicle information.
What to bring: Bring only what the facility allows — phones, tablets, smartwatches, bags, purses, food, drink, books, and currency are not permitted in the visiting room (lockers are provided); generally only labeled prescribed heart medication or an asthma inhaler may be carried in. Money for the person's account is sent through a deposit vendor, never handed over at a visit.
Scheduling: In-person visits are scheduled online through SignUpGenius (the IDOC visitation scheduler); days, hours, and whether a visit is contact or non-contact vary by facility and the person's status, so confirm with the specific prison. A newly committed person is processed at a reception and classification center first — the Northern Reception and Classification Center for men, Logan for women — before transfer.

Mail

Illinois changed how it handles incoming personal mail in 2025, and the change became permanent in January 2026. Personal letters and photos sent to the facility are opened and scanned, and the incarcerated person receives a digital copy on their ICSolutions tablet (a free printed copy is available on request) rather than the original. Address mail with the person’s name and IDOC number, and confirm the current mailing address and format with IDOC and this facility before sending, since the program is recent. Legal mail is handled separately under privileged-mail rules, and publications (books, magazines) must come directly from a publisher, book club, or bookstore. Full rules are in Mail & Packages.
