The Cotulla Unit is a Texas Department of Criminal Justice (TDCJ) state prison in Cotulla, La Salle County, on Interstate 35 between San Antonio and Laredo. It opened in July 1992, holds 606 men in a single building on 36 acres, and its custody levels are G1, G2 and Transient, so a share of the population is between assignments. TDCJ runs Cotulla jointly with the Dolph Briscoe Unit in Dilley as the Briscoe-Cotulla Complex under one senior warden. This guide covers the TDCJ locator, weekend visiting, the Dallas mail routing, Securus phone setup, and the Inmate Trust Fund.

Quick Facts
Visitation
- 1 Contact, Regular, Restricted and Video visits all run Saturday and Sunday, 8:00 AM to 5:30 PM.
- 2 Cotulla runs no weekday slots. Of the units in TDCJ's current directory, only Bill Clements adds Monday, Wednesday and Friday, and there they cover video visits only.
- 3 Hours read from TDCJ's Unit Visitation Schedule on August 29, 2026. Visits are still suspended during a lockdown, so (830) 879-3077 is worth a call before you travel.
- 4 All visits end at 5:30 PM regardless of when you arrive, and arriving more than 15 minutes late can forfeit the slot.
Mail & Letters
- 1 Since September 6, 2023, personal mail, greeting cards and photos go to a Securus processing center in Dallas, not to Cotulla.
- 2 Mail without the full commitment name and TDCJ number is returned to sender.
- 3 Legal mail, media and business correspondence, packages, and publisher-direct books still go to the unit's own address.

Cotulla holds people in Transient status and its own PREA audit puts the average stay at about five months, so a locator result goes stale faster here than at a general-population unit.
