Inmate Money

Every federal prison has a Commissary which was created to provide an account for prisoner money and for purchasing things not issued regularly by the prison.

How to Send an Inmate Money

Family, friends, or other sources can deposit money to these Commissary accounts by sending it by Western Union and the U.S. Postal Service.

Via U.S. Postal Service: An inmate’s family and friends can to send prisoners money in the mail and must send funds to this address and follow the rules listed below:

Federal Bureau of Prisons
Insert Valid Committed Inmate Name
Insert Inmate Eight-Digit Register Number
Post Office Box 474701
Des Moines, Iowa 50947-0001

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

  1. At a physical location using cash. In order to locate the closest agent, you should call 1-800-325-6000 or visit
  2. On the phone with a credit or debit card: Call 1-800-634-3422 and choose phone promt option 2.

    what is the dollar limit on a prisoners money account. This document doe not specify. Is it a variable according to the prisoner are all prisoner’s treated the same?

  3. P. M. Ph***n says:

    Peace to you,
    I correspond with an inmate as a work of mercy with a Church organization. I have a humble question not knowing who to ask. In my correspondence this inmate said that he will be released in a few months. The halfway house will not take him due to his illness (not offense). Also it is in a city where he has no roots. Question: will he be simply dumped back into society with no money, residence to go to, medical help, job opportunities or training? This is the feeling I am getting, maybe just fears.
    Or does the facility do their best to help them get re-entered into society by the many agencies offering services for inmates – which this city has at least 54 of? Please re-assure me that they should not be afraid to get out, and have a glimpse of hope for rehabilitation. This is a general question for my knowledge. I pray that you will help those who are released in this way. May God bless you in your work. Peace and goodness of the Lord be with you. He too is watching.
    Thank you for your kind answer.

    Am I allowed to mail books from my home to a new inmate, or do they need to be mailed from “Amazon” or another reputable place/store? Thanks!

  5. If an person is sent and is in need of psychological help does this occur at this facility? Do they do assessments on the prisoner’s?
