Inmate Money

Every federal prison has a Commissary which was created to provide inmates a bank type account for inmate funds and for buying things not issued regularly by the facility.

How to Send an Inmate Money

Friends, family, or other people can deposit money to inmate’s Commissary accounts using the U.S. Postal Service and Western Union.

Via U.S. Postal Service: An inmate’s family and friends can choose to send prisoners money in the mail and must send funds to this address and follow the rules written 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 has to be in the form of 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 placed on a 15-day hold, and in this time the prisoner will not get the funds. The Bureau of Prisons will return any funds that don’t have valid prisoner info if the envelope it was sent it has an adequate return address. Cash and checks will not be deposited to the prisoner’s account so do not send any cash or checks.

Via Western Union Quick Collect Program: Prisoner’s friends and family may also send prisoners money with Western Union’s Quick Collect Program. Money sent to a prisoner using the Western Union Quick Collect Program can be sent by one of these methods:

  1. At Western Union location using cash. In order to locate the closest agent, you should call 1-800-325-6000 or visit www.westernunion.com.
  2. By phone with a credit/debit card: Call 1-800-634-3422 and select menu option 2.
  3. On the web with a credit/debit card: Go to www.westernunion.com and choose “Quick Collect.”

For the Western Union Quick Collect transaction, this info must be included:

  1. Correct and valid Inmate Eight-Digit Register Number (entered with no spaces or dashes) followed immediately by Inmate’s Last Name
  2. Committed Inmate Full Name entered on Attention Line
  3. Code City: FBOP, DC

If the wrong register number and/or name are used and accepted and sent to that prisoner, funds might not get returned to you.
