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.
