Phone Contact

Individuals in custody cannot receive telephone calls but can make collect calls to those on their approved calling list. If you want to receive collect calls from an individual in custody, you will need to write the individual in custody and ask to be placed on their approved calling list.

Individuals in custody have scheduled times when they can make collect calls, which are determined by their living unit's schedule. All telephone calls are subject to monitoring and recording at any time by Departmental staff unless prior special arrangements have been made to make or receive an unmonitored attorney call. All requests for unmonitored attorney calls must be processed by a member of IDOC’s legal staff.

Participation or initiation of three-way calls by individuals in custody is strictly prohibited by IDOC rules and will result in disciplinary action.
