Warning: After January 15, 2026, mail that should have gone to the Digital Processing Center but is sent to Cibola Unit will be returned to the sender.

Legal mail is not part of the digital scanning program. As of December 5, 2025, the address and process for sending legal mail to someone at Cibola Unit has not changed. Do not send legal mail to the Digital Processing Center in Texas. It must be addressed and sent to the centralized Phoenix processing address (not the unit).

Letters, greeting cards, your child's drawings, printed photos: these are the kinds of items that get scanned into the digital mail system. Starting December 15, 2025, send them to the Digital Processing Center in Texas, not to Cibola Unit. Anything that isn't simple paper correspondence? Pause and double-check. Magazine subscriptions, books, and other publications are not accepted for scanning. Those have to go through the centralized Phoenix processing address instead. Same goes for packages. And as noted above, legal mail also skips the scanning system and must be sent to the Phoenix processing address.

Rule of thumb: Letters, cards, drawings, and photos go to the Digital Processing Center for scanning. Legal mail, publications, and packages do not.

There's a one-month transition grace period from December 15, 2025 through January 15, 2026. During that window, if you accidentally send something to the prison complex that should have gone to the Digital Processing Center, ADCRR says it will still be processed and provided to the inmate. Once the grace period ends, mistakes get more costly. From January 15, 2026 onward, mail sent to the wrong address will be returned to you.

Need help? Digital mail support is available 24/7 through Securus Customer Service at (800) 844-6591. When sending personal mail, use the Digital Processing Center addressing format (inmate's full name + ADCRR number, prison complex and assigned unit) so it routes correctly.
