What Goes to Dallas, What Goes to Gatesville
The Texas Department of Criminal Justice (TDCJ) no longer delivers personal mail to its units. Letters, greeting cards and photos go to a Digital Mail Processing Center:
Texas Department of Criminal Justice
[Full First and Last Name] [TDCJ Number]
PO Box 660400
Dallas, TX 75266-0400
The center scans each item in color and delivers it to his tablet, normally within about three business days. People without a tablet get printed copies. Scanned originals are held for 90 days and then destroyed, unless you enclose a self-addressed stamped envelope to have the original sent back to you.
Two details decide whether a letter arrives at all. The envelope needs his full commitment name, meaning the name TDCJ has on record and not one he goes by, and his eight-digit TDCJ number. Mail missing either is returned to sender.
These still go to the unit itself, not to Dallas: legal mail, special mail, media correspondence, business and agency correspondence, packages, publisher-direct books and magazines, and government checks. Anything needing his signature goes to the unit addressed care of the Law Library.
Alfred D. Hughes Unit
[Full First and Last Name] [TDCJ Number]
3201 FM 929
Gatesville, TX 76597
And here is where Hughes has a wrinkle of its own. TDCJ publishes two ZIP codes for that street address. The unit directory says 76597. The unit’s own November 2024 PREA report says 76528, which is also the ZIP TDCJ uses for the O’Daniel and Woodman units nearby. Both documents are TDCJ’s.
We use 76597 here because it is the value in TDCJ’s mailing directory, its reference for correspondence. TDCJ has not reconciled the two, so a call to (254) 865-6663 is worth it before sending anything that has to reach the unit instead of Dallas.
Photos, Books and the Publisher Rule
Photos follow the same route as letters. They go to the Dallas address, get scanned in color, and reach him on the tablet. Do not send them to Gatesville.
Books and magazines are a special case. TDCJ’s own page contradicts itself: the prose says books and magazines go to the unit, while the routing table further down the same page lists books under digital mail. Before sending a book, confirm on (254) 865-6663.
What is consistent across TDCJ’s guidance is the publisher-direct rule: books and publications are expected to come from a publisher or an established retailer, not from a private individual, and those shipments go to the unit instead of to Dallas.
Packages of any kind go to the unit, not to the processing center, and they are subject to the unit’s own approval rules. This is not a route for sending everyday items, and anything unapproved is refused at the gate.
If printing and posting is the part that gets in the way, Pigeonly is another way to do it. You upload a letter or photos from your phone and we print and mail them under that prison’s mail rules, so there is no printer, no stamps and no trip to the post office. It sits alongside the official postal route above and does not replace it, and the Dallas address is still where the letter physically goes.
