How to send mail to someone at HighTower Unit: digital mail vs. unit address
Sending mail to someone at HighTower Unit? Your first choice is where to send it: the TDCJ Digital Processing Center handles most personal letters, photos, and greeting cards, while the unit's direct address is reserved for specific exceptions like legal mail and anything requiring an inmate signature.
Most personal mail goes through TDCJ's Digital Processing Center. On your envelope, include the inmate's full first and last name along with their TDCJ number, then use this exact address: Texas Department of Criminal Justice Inmate's Full First and Last Name + TDCJ Number PO Box 660400 Dallas, TX 75266-0400
Certain mail still goes directly to the unit rather than the Digital Processing Center. For these items, your envelope needs the inmate's name, TDCJ number, and the unit's mailing address. Double-check the official TDCJ unit listing on their website - it'll give you the correct address for HighTower Unit and show exactly how to format it.
Prohibited Stationery
- ✓ Do not mail food, clothing, jewelry, toiletries, or packages to an inmate.
- ✓ Do not send “extra items” tucked into a letter if they fall into those categories - those are not allowed by mail.
- ✓ The only items that may be mailed (as items) are books, magazines, and newspapers.
- ✓ If your loved one needs writing paper and envelopes, those can be provided through the indigent correspondence supply program.
- ✓ Stationery can also be purchased through the unit commissary, including options available to families/friends through the eCommDirect program.
- Choose the route (Digital Processing Center vs. unit mail) - Personal letters, greeting cards, and photos generally go to the Digital Processing Center; some exceptions (like legal mail or items requiring an inmate signature) go to the unit.
- Write the inmate’s full name and TDCJ number - Put the inmate’s full first and last name plus their TDCJ number on the envelope so it can be matched to the right person.
- Address it correctly - For Digital Processing Center mail, use: Texas Department of Criminal Justice, Inmate’s Full First and Last Name + TDCJ Number, PO Box 660400, Dallas, TX 75266-0400. For unit mail, use the inmate’s name, TDCJ number, and the unit’s official mailing address as published by TDCJ.
- Keep contents mail-safe - Don’t include food, clothing, jewelry, toiletries, or any kind of package contents; those aren’t allowed through the mail.
Note: Books, magazines, and newspapers follow different rules than letters - they're the only physical items allowed by mail and go through unit channels. Your loved one can get paper and envelopes through indigent supplies or purchase stationery via commissary/eCommDirect.
