Can I use UPS to ship to a P.O. Box?

Not technically, no.

If a recipient has a P.O. Box address and a UPS service is selected:

• The recipient's telephone number must be included on the label.
• The package that is addressed to a P.O. Box may be delayed.
• It will not be covered by any UPS Service Guarantee.
• May require an address correction charge of $12.

NOTE: Army Post Office (APO) and Fleet Post Office (FPO) addresses are not accepted for most UPS services.

If you are attempting to ship to a PO Box using a UPS service that does not deliver to that address, you will see a warning in the app.
