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, title or content they accept.
At checkout, the Inmate numbers can now be included in the Last Name field. You can also enter the recipient's inmate number in the "Apt, Suite, etc." field of the shipping address.
UPS is generally not accepted by correctional facilities, so we always use USPS when shipping magazines and books to jails and prisons.
