General Information

Below you will find general information about the telephone policy at Oklahoma State Prisons

The Oklahoma Department of Corrections encourages communication between offenders and their family. Telephones are provided for this purpose. No phone calls can be made until the offender has been issued a Personal Identification Number (PIN) by staff. Offenders are prohibited from using another offender’s PIN. Offenders cannot share any other offender’s calls.

The number of individuals an offender will be allowed to call will be in accordance with OP-060107 “Systems of Incarceration.” Offenders may only request changes to their authorized telephone list every 120 days or during scheduled classification actions. The authorized number of telephone numbers is as follows:

• Level I - legal/clergy only
• Level II – calls limited to four numbers only
• Level III – calls limited to eight numbers only
• Level IV – calls limited to ten numbers only

Due to offenders only being allowed to make collect calls, family members and friends of offenders can set up a prepaid account through GTL. The number to call is: 1-877-650-4249. Collect calls may also be made to cell phones by calling the same number and setting up an account through GTL.
