Any books being sent into a prison or jail must be done through a publisher. Books will be rejected by the mail room personnel if they are sent in by an individual. They deem it a security risk if it is not coming from the publisher as a source.
Amazon.com delivers to penitentiaries, but we strongly suggest you contact the prison first to confirm that they accept deliveries and to note any special regulations the prison might have. Some prisons don't allow delivery of hardcover books. Others place a limit on the number of items contained in a package.
The label on the outside of the packages will indicate only the destination address, Amazon.com's name, and return address. Special labels or instructions to the packages can't be attached to the package. Gifts can't be sent anonymously to inmates; the sender's billing address will appear on the order invoice.Because inmates cannot sign for deliveries, packages must be sent via U.S. Mail. While Amazon.com often sends packages via U.S. Mail, they also use UPS and FedEx. There is no way for customers to request a specific shipper.
