How to Write to Someone at Lopez Unit: Correct Mailing Format, Books, and Mail Rules

Every envelope to the Lopez Unit needs three things: the incarcerated person's name, their TDCJ number, and the unit address. Get any of these wrong and your letter stalls out. Double-check that TDCJ number before you seal it - one wrong digit can send your mail nowhere.

Want to send reading material? Where it ships from matters. Newspapers, magazines, and books can only reach someone at the Lopez Unit if they come directly from the publisher, a publication supplier, a bookstore, or an online bookseller. You can't mail a book from home, even if it's brand new. Order through an approved seller so it ships straight to the unit.

Need something faster than postal mail? You can send e‑messages to Lopez Unit inmates through JPay (www.jpay.com). There's setup and payment involved, but it's a practical option for quick updates or encouragement without waiting on the mail cycle.

1. Create or sign in to your JPay account - use the JPay site to register and access e‑messaging.
2. Buy electronic stamps - stamps are required to send e‑messages through JPay.
3. Write and send your e‑message - compose your message online and submit it through the JPay system.

• ✓ Confirm the person is currently assigned to the Lopez Unit and has privileges before you send anything.
• ✓ Call the unit for final confirmation before you travel or rely on a mailing plan.
• ✓ Verify the correct unit address using the official TDCJ unit list or agency guide.
• ✓ Re-check that you wrote the correct name and TDCJ number on the envelope.
