Where to Actually Send Mail for TDCJ Inmates: Digital Processing Center vs. Unit Address

For everyday correspondence - letters, greeting cards, photos - send everything to the Digital Mail Processing Center, not the prison unit. Use this exact format: Texas Department of Criminal Justice Inmate's Full First and Last Name + TDCJ Number PO Box 660400 Dallas, TX 75266-0400 The full name and TDCJ number are how your mail gets matched to the right person once it arrives for processing.

Unit Exceptions

• ✓ Legal mail (send to the inmate’s unit)
• ✓ Media mail (send to the inmate’s unit)
• ✓ Books, magazines, packages, and other subscriptions from verified publishers or sellers (send to the inmate’s unit)
• ✓ Newspapers, magazines, and books must come directly from the publisher, publication supplier, bookstore, or online bookseller, and they’re subject to review and rejection under correspondence rules

These categories go directly to the unit because they're handled differently. Legal and media mail follow separate procedures. Publications and packages must come from approved sellers - they can be reviewed and rejected under TDCJ correspondence rules.

No tablet? Your mail still gets through. TDCJ prints black-and-white copies of scanned correspondence for inmates without tablets.

Addressing and Rejection Tips

• ✓ For personal mail going to the Digital Mail Processing Center, use the inmate’s full first and last name plus TDCJ number.
• ✓ Use this address for the Digital Mail Processing Center: PO Box 660400, Dallas, TX 75266-0400.
• ✓ If you’re sending something that must go to the unit, put the inmate’s name, TDCJ number, and the unit address on the envelope.

1. Identify what you mailed - If it was legal mail, media mail, or a book/magazine/package/subscription from a verified publisher or seller, it needs to go to the inmate’s unit (not the Digital Mail Processing Center).
2. Fix the addressing - For the Digital Mail Processing Center, make sure you used the inmate’s full first and last name plus TDCJ number. For unit delivery, make sure the envelope includes the inmate’s name, TDCJ number, and the unit address.
3. Ask for the next step - If it’s still unclear why it didn’t go through, contact the unit or follow TDCJ’s mail guidance for how to resend it correctly.
