About the PO Box Blocker Pro
PO Box Blocker Pro automatically checks shipping addresses at checkout and blocks undeliverable locations before orders are placed. Stop deliveries to PO boxes, parcel lockers, locked bags, private bags, and APO/FPO addresses. You can also restrict delivery by country, state, city, or postal code to ensure orders only go where you can ship.
Set up bypass rules for specific products, variants, or collections that are allowed to ship anywhere. Customize your checkout message to help customers correct their address. Test any address using the built-in tester before going live.
Works seamlessly with standard checkout and Shop Pay across all Shopify plans. No theme edits required.
