The Bureau of Prisons encourages correspondence on a wholesome and constructive level between inmates and members of their families, friends and other community contacts. Outgoing mail is placed in the mailboxes located in the housing units. Outgoing mail will be inspected by staff and must remain unsealed. The outgoing envelope must have the return address in the upper left-hand corner as follows: Inmate’s name, register number, Federal Correctional Institution, P.O. Box 1000, Oxford, WI 53952. Inmates are responsible for the contents of all of their letters. Correspondence containing threats, extortion, etc., may result in prosecution for violation of Federal laws as well as disciplinary action. Inmates may be placed on restricted correspondence status based on misconduct or as a matter of classification. The inmate is notified of this placement and has the opportunity to respond. Mail is distributed Monday through Friday (except holidays) by the Evening Watch Officer in each unit. The number of incoming letters an inmate may receive will not be limited unless the number received places an unreasonable burden on the institution. All incoming mail must contain your register number on the envelope to aid in the prompt delivery of mail.
