New Legal Mail Process – Registration and Control Number Access

Since July 2021, ODRC has been converting to a new legal mail process that requires senders to register and use control numbers on mail sent to incarcerated persons. ODRC will soon begin enforcing the requirement that all legal mail contain a control number. This means that mail without a control number will soon be processed as ordinary mail, i.e., opened, copied and delivered to the addressee.

If you have questions about the process or difficulties registering or obtaining a control number, please send an email to
