About PO Box Blocker by mnurksr

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. Automatically block P.O. Box, APO, and FPO addresses during checkout. Restrict shipping to specific states, provinces, or zip codes easily. Seamless Shopify Checkout integration with zero coding or theme changes. Show more Show less
