Offender Telephone System

The Offender Telephone System (OTS) allows eligible inmates to make paid telephone calls to friends and family, in accordance with the TDCJ Disciplinary Rules and Procedures for Offenders.

Information or registration:

Before you can receive calls from a TDCJ inmate, you must first register your telephone number:

  • Internet:
    Note: You will need the inmate's TDCJ ID Number to register to receive phone calls from him or her. If you do not know their number you can find it through the online inmate search at or by phone at (936) 295-6371 or (800) 535-0283. The phones are answered from 8 a.m. to 5 p.m. Monday - Friday.
  • Telephone: (866) 806-7804

Telephone calls can be placed in the following manner:

  • Collect calls - charges are accepted when the inmate calls.
  • Friends and Family Prepaid - the owner of the telephone number establishes an account in which to deposit money to pay for the inmate's calls.
  • Offender Telephone Prepaid Debit Account - the inmate or family can deposit money into the inmate's account.

The following rules apply to the system:

  • Phones are available from 7:00 a.m. - 10:00 p.m., unless conditions dictate a change.
  • Calls are limited to 30 minutes.
  • You will hear a warning message one minute before being disconnected.

  • Calls may only be made to home landline telephone numbers, post-paid cell phones, and pre-paid cell phones. No calls are allowed to internet services, 800 numbers, businesses, pay phones, or international numbers.
  • To receive calls, the name on the registrant's driver's license or state identification card must be reflected on their telephone listing or bill.
