Which items are accepted/prohibited at prison facilities?   Restrictions on packages at correctional institutions vary from one institution to another. Most facilities will NOT accept Hardcover books and Audiotapes. Before placing an order, make sure that the content of the package you are sending is within the guidelines set by the institution. If you are unsure of which items are considered acceptable, please contact the facility first before placing an order. You can also send the packages to a residential address and deliver the item personally. Many packages are returned to us because they contain restricted/prohibited items.
