Sending mail to someone at Sayle Unit: when to send to the Dallas digital processing center vs directly to the unit
Most personal mail for people at Sayle Unit goes through TDCJ's Digital Processing Center in Dallas. But a few categories need to go directly to the unit—send them the wrong way and you'll face delays or rejection.
For regular personal mail like letters, address your envelope to the Digital Processing Center: Texas Department of Criminal Justice Inmate's Full First and Last Name + TDCJ Number PO Box 660400 Dallas, TX 75266-0400
Note: Include the person's full first and last name along with their TDCJ number on the envelope. This is how processing staff match mail to the right person.
Exceptions
- ✓ Legal mail
- ✓ Media mail
- ✓ Books, magazines, packages, and other subscriptions from verified publishers
For the exception categories above, skip the Dallas address entirely. Send those items straight to Sayle Unit using the official mailing address listed on the TDCJ website.
Whichever route you use, the basics stay the same: include the person's full name, their TDCJ number, and the correct address. Not sure about the exact format? Check the unit addresses on the TDCJ website to avoid misrouted mail.
Quick rule: Personal letters go to the Dallas Digital Processing Center. Legal mail, media mail, and items from publishers or verified subscriptions go directly to Sayle Unit.
No tablet? Mail sent through the Digital Processing Center still gets delivered - it just arrives as a black-and-white printed copy at the unit.
