Exclusive to packages with prepaid UPS or FedEx shipping labels, you can come to the book return window around the corner from the Phillips Hall Post Office.
If your shipment requires different packaging
Note that USPS (US Mail) branded shipping products are not permissible for use with UPS or FedEx shipments. The Post Office will not provide you any for this use. If you present a UPS or FedEx shipment in USPS packaging, we will not be able to accept it and your shipment will have to be repackaged.
This service is exclusive to prepaid UPS and FedEx shipments. All US Mail packages, prepaid or otherwise are still handled as normal at the postal window.
NOTE: Package tracking is the responsibility of the sender. Mail Services keeps no records of outgoing prepaid shipments. If you don’t have a copy of your tracking info, just take a pic of your shipping label before you hand off your package to us.
