Visitation

Terrell Unit offers in-person visitation on weekends only—Saturday and Sunday, 8:00 a.m. to 5:30 p.m. Regular visits last two hours, and each inmate can receive just one visit per weekend. To schedule, you'll need to create your own TDCJ Online Visitation Scheduler account (staff can't set one up for you). After registering, you'll receive an email with a 7-digit validation code, and you must complete the Background Questionnaire to finish setup. Each inmate can have up to 10 people on their Visitors List, with changes limited to once every six months for institutional inmates. Visitors 18 and older need a current government-issued photo ID with a physical address. Follow the dress code and leave prohibited items behind—no cell phones, and only coins up to $35. Contact visits allow limited physical contact. If you're traveling more than 250 miles one way, you may qualify for extended visits up to four hours. Confirm the inmate's assignment and visitation privileges before you go.

Communication

Want to get phone calls from an inmate at Terrell Unit? Start by registering your telephone number at texasprisonphone.com and entering the inmate's TDCJ ID. Calls run through the vendor system, and your number typically needs to go through registration steps and be added to an approved phone list before calls can connect. Electronic messaging and tablet services are handled through approved vendors too. Account setup usually starts with creating an account tied to your email address. Read the prompts closely: some vendors don't let you delete an account or change the email after it's created, and new registrations often require a validation email with a 7-digit code. Availability can vary by unit rules, custody level, and inmate privileges.

Mail & Letters

Terrell Unit switched to TDCJ's centralized digital mail system on Sept. 6, 2023. Incoming personal mail—letters, cards, and photos—goes to a Digital Mail Processing Center where it's scanned and uploaded to the inmate's electronic account. Address your envelope with the inmate's full first and last name, TDCJ number, and the unit address. Mail it to: Texas Department of Criminal Justice, Inmate's Full First and Last Name + TDCJ Number, PO Box 660400, Dallas, TX 75266-0400. Newspapers, magazines, and books are only accepted when shipped directly from the publisher, supplier, bookstore, or an online bookseller. If the inmate doesn't have a tablet, they receive black-and-white printed copies of scanned correspondence. Legal or privileged mail follows a separate process.

Sending Money

Sending money to someone at Terrell Unit is restricted to approved senders. Only people on the inmate's Approved Visitation List or Inmate Telephone List can deposit funds (policy effective September 1, 2020). To become an approved eCommDirect sender, have the inmate add you to their Approved Visitation List, or register your phone with Securus to get placed on the Approved Phone List. eCommDirect sets quarterly spending limits: $70 for Jan–Mar, $70 for Apr–Jun, $70 for Jul–Sep, and $95 for Oct–Dec (Holiday Spend). Fees apply: $3.75 per purchase transaction, plus deposit fees of $2.50 and 2.25% of the deposit amount.
