Inmate Money

Each state prison has a Commissary that was created to provide an account for inmate funds and for purchasing things not issued regularly by the prison.

How to Send an Inmate Money

Family, friends, or other sources may send funds into these Commissary accounts with the U.S. Postal Service and Western Union.

Via U.S. Postal Service: An inmate’s family and friends can choose to send inmates money through the postal service and must send those funds to this address and do so in accordance with the policies written below:

The funds must be in a money order that is made out to the inmate’s full committed name and complete eight-digit register number. You are advised to use a U.S. Postal Service money order, since all non-postal money orders processed through the National Lockbox will be kept for a 15-day hold period, and during this hold period the prisoner will not have access to the depsoit. The Bureau of Prisons will return funds that don’t have appropriate inmate info but only if the envelope it was sent it has a valid return address. Personal checks and cash will not be accepted so do not send any checks or cash.

  2. Ronda says:

    How long will my husband be in DRDC till he can call home? It feels like I’m the one who is suffering not hearing from him. I know he was transferred from county jail to DRDC by me calling the county jail over and over. But now I’m not getting no answers again. Please help . My question is why has my husband not. calling me to let me know whats going on.

  3. Lidia says:

    I came to pickup my son from this facility and the staff inside was nice but one of those prison guard was such an ahole.He was patrolling outside the gate and we were several people waiting for our love ones and. He kept coming back to us talking down to us and giving orders also. I felt like telling him we are not Doc inmates so back off but I just but my tongue Doc Department needs some training. On how to treat citizens

  4. Tammy says:

    My husband had been in DRDC since 4-22-17 when will he be able to call me? I set up a pre paid account up! I also been writing him through mail and through that Jpay email does that really work and I also sent him money for his books through jpay. Does that really work or is it a scam

  5. Ann says:

    What company do we use to setup a prepaid telephone or calling card account for inmates? I’ve been searching for a few hours and still can’t figure it out. I did find the JPay email and have sent 2 out but think it says that it can take 24-48hours to be delivered… I’m sorry to see that so many people are having the same problems contacting loved ones and that this has been an issue for so long. :(

    Hang in there everyone, we can survive this!

  6. Angela Martinez says:
