How to Write to Someone at Lopez Unit: Mailing Rules and Publisher-Only Books

Getting mail to someone at the Lopez Unit is straightforward if you format the envelope correctly and follow the publisher-only rule for books and magazines. Here's what you need to know before sending anything.

Every envelope you send to the Lopez Unit needs three things: the inmate's full name, their TDCJ number, and the unit address. The mailroom uses these details to route your letter correctly. Write them clearly and double-check for typos before you seal the envelope.

Not sure you have the right address? Confirm it before mailing anything. TDCJ publishes unit addresses on the agency website, and you can also find them in the family guide.

Books, magazines, and newspapers must come from an approved source: the publisher, a publication supplier, a bookstore, or an online bookseller. This is TDCJ's publisher-only rule. If you try mailing a book yourself (even a brand-new one), it will likely be rejected because it didn't come from an approved sender.

Note: Even when a book, magazine, or newspaper is sent from an approved seller, it is still subject to review under the correspondence rules and may be rejected.

Want an alternative to postal mail? TDCJ allows e-messages to inmates at the Lopez Unit through JPay.

E-messages aren't free. You'll need to purchase electronic stamps through the JPay site before you can send one.

Practical Checklist

  • Confirm the Lopez Unit address using the TDCJ agency website or the family guide.
  • Double-check you wrote the inmate’s TDCJ number correctly on the envelope.
  • If you are sending books, magazines, or newspapers, order them so they ship directly from the publisher, publication supplier, bookstore, or online bookseller.

Reminder: Approved-source publications are still reviewed and can be rejected under TDCJ correspondence rules.
