Inmate Money

Every state prison has a Commissary which serves to provide inmates a bank account for inmate money and for buying items not issued to inmates by the facility.

How to Send an Inmate Money

Friends, family, or other people may deposit money into these accounts using Western Union or by mail.

Via U.S. Postal Service: Inmates’ families and friends can to send inmates money through the mail and have to send those funds to the following address and follow the rules given below:

The money have to be in the form of a money order made out to the prisoner’s full committed name and complete eight-digit register number. It is advisable 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, and in this time the prisoner will not have access to the funds. The Bureau of Prisons will send back money orders that do not have appropriate inmate info but only if the envelope you sent it in has a valid return address. Checks and cash will not be deposited to the inmate’s account so do not send any cash or checks.

    My husband is an inmate at Sierra Conservation Center until 9/2016. He is in there for evading. Right now him and his bunkmate are in Ad-Seg, “the hole”, solitary confinement, until at least May 2014 for a fraudulent charge which occurred AFTER my husband filed a staff misconduct complaint against a Sergeant and a Corrections Officer for staff misconduct. Two days after he filed the complaint, which his bunkmate signed as a witness, the Sergeant and the C/O threatened them that if my husband did not drop the complaint, they would end up in the hole by the end of the week. My husband and his bunkmate continued to be threatened and harassed by every C/O they came across until they were put in Ad-Seg only two days later. Even after they were put in Ad-Seg, my husband said ” they walk all the way over here everyday, just to threaten us. We wont even leave our cells and try not to be alone for fear that they will plant something in our stuff or beat us to death.” This is not the first time nor will it be the last time that this type of thing happens at Sierra Conservation Center. My husband will not drop the complaint, which according to the Ombudsman I talked to recently, is not in my husbands file. I received all of the paperwork, police reports, 115 reports, Ad-Seg admittance papers for both of the men and it is such a mess of errors its a wonder how they think no one would see it. One thing to remember, when a prisoner goes into Ad-Seg, even though they are supposed to be allowed to keep legal papers, all their property is taken from them and if they have enough money on their books it gets shipped home, if not it gets donated or actually thrown away. This typically includes all legal paperwork they have, including complaints they have filed, so there is no original copy. All they do is pull the complaint out of the file and throw away the original and there is no one who will usually look any further. Well, they have it wrong on this one. I have the log number and someone needs to find it. This prison is currently under investigation by the UN for the conditions in their Ad-Seg and SHU departments and the misconduct complaints by inmates are very rarely ever reviewed. If they do make it outside of the prison walls the ratio of complaints that get processed is approx. 1/12 from what I have read. If the families of these inmates helps them, typically the inmates get punished until the family butts out. Although my research has shown this to be true at any of California’s prisons, S.C.C. seems to be the worst for a low level prison. My husband and I are not going to give up and I hope that anyone else in the same position doesn’t either. The only way to be heard by the CDCR or S.C.C. is publicity…and lots of it. Wish us luck and be careful.
