Description

Instantly block P.O. Boxes, APO, and restricted states at checkout. Prevent costly shipping errors.

FedEx and UPS often reject P.O. Box and military (APO/FPO) addresses, causing fulfillment delays, returned packages, and extra shipping costs. PO Box Blocker solves this by automatically validating shipping addresses in real-time during checkout. If a customer enters a restricted address, they cannot complete the purchase until they provide a valid physical address. You can also block specific states or zip codes to fully control your shipping zones. Set up in seconds.
