Sending Mail to William P. Clemens Unit: Why Letters Go to Dallas and Exceptions You Need to Know
Trying to mail a letter to someone at the William P. Clemens Unit? Here's the catch: it usually doesn't go to the unit at all. Most personal mail gets routed to a TDCJ processing center in Dallas, where it's scanned and delivered digitally.
TDCJ switched units - including the William P. Clemens Unit - to a digital mail platform on September 6, 2023. Now, most incoming physical mail gets routed to the TDCJ Digital Mail Processing Center in Dallas. Staff there sort and scan it, then upload the images to the inmate's secure tablet. The goal? Reduce contraband while still letting people receive letters and photos. It's just delivered differently than you might expect.
For mail going through the Dallas Digital Processing Center, use this exact format. Don't skip the TDCJ number - leaving it off can slow things down significantly. Address the envelope to: Texas Department of Criminal Justice; Inmate's Full First and Last Name + TDCJ Number; PO Box 660400; Dallas, TX 75266-0400.

Want to avoid delays? Label everything clearly. Use your loved one's full first and last name, and always include their TDCJ number. Keep in mind what happens once your letter reaches Dallas: it gets scanned and uploaded to the inmate's secure tablet. You're mailing paper, but the delivery is digital. If your loved one doesn't have tablet access, they may receive correspondence differently - worth confirming what they can actually view.
Note: Since most personal mail is scanned and uploaded, anything that doesn't work cleanly in that process may not arrive the way you expect. Unsure about a specific enclosure? Verify what's allowed before sending.
- Double-check where the mail should go - If it’s personal mail, it should go to the Dallas Digital Mail Processing Center to be scanned and uploaded to the inmate’s secure tablet; legal mail and verified subscriptions are handled differently.
- Confirm your addressing details - Make sure you used the inmate’s full name and included the TDCJ number, since that’s how mail is matched and processed.
- Call the unit before you resend anything time-sensitive - Unit information can change, so call for final confirmation before you put a corrected letter or exception item back in the mail.
