The Cook County Department of Corrections requires visitors to submit a Visitor Application before visiting an inmate, according to the Cook County Sheriff's Office. Applications may be rejected if the visitor lies on the application or is involved in other correctional procedures (such as being on probation or house arrest).
CCDOC conducts background checks on all potential visitors before approving applications. Approved visitors must bring at least one form of valid photo ID, explains CCDOC. Accepted forms of ID include a driver's license, a passport, a U.S. military identification card and a school ID card for minors who are accompanied by an approved visitor. Visitors must be searched before entering the Cook County Correctional Center. Banned items, including weapons, drugs, drinks, books, food and cameras, cannot be in the visitor's possession during the visit.
