Are you wondering if it's possible to ship to a P.O. Box through UPS?
Unfortunately UPS only accept shipments to a valid street address, so they don't deliver to P.O. Boxes.
If a shipper should use a P.O. Box address, the recipient's telephone number must be included on the label. Your package that is addressed to a P.O. Box may be delayed, will not be covered by any UPS Service Guarantee, and will require an address correction charge.
Additionally, Army Post Office (APO) and Fleet Post Office (FPO) addresses are not accepted from the Carrier.
