How to Address Your First Letter to Someone at Beto Unit

Start with the inmate’s full name on the envelope. That’s the basic identifier mailroom staff use to sort and match mail to the right person, so don’t use nicknames or partial names if you can avoid it.

Include the inmate's TDCJ number (also called the SID/TDCJ number) alongside their name. This 8-digit number is what separates people with similar names, and mail won't process correctly without it.

Write the Beto Unit address on the envelope. This routes your letter to the correct facility - even a perfectly written letter can sit in limbo if the address is missing or outdated.

1. Go to the TDCJ Offender Search - this is the fastest way to confirm the correct TDCJ/SID number to put on the envelope.
2. Search by the person’s name - enter the inmate’s name as completely as you can so you pull up the right record.
3. Copy the 8-digit TDCJ/SID number - use that exact number on your envelope along with the inmate’s full name.

Find the Beto Unit's mailing address on TDCJ's official unit directory or from the inmate's listing. Double-check it before sending your first letter - using the current address prevents unnecessary delays.

Examples-pitfalls

• ✓ Inmate Full Name
• ✓ TDCJ/SID Number (8 digits)
• ✓ Beto Unit (Unit Address)

Letters are straightforward, but sending reading material has extra rules. At Beto Unit, books, magazines, and newspapers must come directly from the publisher, a bookstore, or an online bookseller - not from you. Even then, they're subject to review and can be rejected under the facility's correspondence rules.
