To ensure delivery, it is best to contact the correctional facility to which you will be shipping to inquire about any specific rules they have regarding what can and cannot be accepted, such as subject matter, book format, and what courier services they do and do not accept.
If a shipment is returned to us by the facility, we recommend you contact the facility for details about why it was returned, as that information is not provided to us.
Inmate numbers should be included in the Last Name field.
Most correctional facilities will accept only USPS parcels. If your order must be shipped by USPS, you need to check the box at the top of the Address form that states: "This address is a PO Box". Select this box while adding the Correctional Facility as a shipping address during the Checkout process.
