How TDCJ's Digital Mail System Works (Where to Send Letters and What Happens Next)

As of September 6, 2023, TDCJ moved all units to a digital mail platform. Your letter no longer goes directly to the unit as a paper document. Instead, incoming mail gets sent to a Digital Mail Processing Center. Staff there sort it, scan it, and upload it to the inmate's secure tablet. Your loved one reads your letter on screen rather than holding the original pages.

For personal mail going through the digital system, address it to TDCJ at the Digital Processing Center. Include your loved one's full first and last name plus their TDCJ number so it reaches the right person. Use this exact address format: Texas Department of Criminal Justice Inmate's Full First and Last Name + TDCJ Number PO Box 660400 Dallas, TX 75266-0400

• ✓ Texas Department of Criminal Justice
• ✓ Inmate’s full first and last name
• ✓ Inmate’s TDCJ number
• ✓ PO Box 660400, Dallas, TX 75266-0400 (for personal mail sent to the Digital Processing Center)
• ✓ The unit address on the envelope when you are mailing something that must be sent to the unit

No tablet? Your loved one still gets your mail. TDCJ provides inmates without tablets black-and-white printed copies of their correspondence.

The Digital Mail Processing Center handles incoming mail that gets scanned and uploaded to tablets, but not everything goes through that system. Some categories (legal mail, media mail, certain books and subscriptions) are exceptions and go directly to the unit. This is why you'll still see guidance about including the inmate's name, TDCJ number, and unit address on the envelope. Unit addresses are listed on the agency website, so you can confirm the right destination before mailing anything that bypasses the digital processing center.
