AddressFence: PO Box Guard

Block PO boxes, lockers and restricted ZIP regions.

AddressFence helps merchants prevent failed deliveries by publishing checkout-native address rules. Configure PO Box, parcel locker, ZIP/postal, region, allowlist, and exception rules, test them in the simulator, publish to Shopify validation, and roll back when needed. The app does not store shopper shipping addresses from checkout.

• Publish checkout-native address rules without theme code.
• Block PO Boxes, lockers, ZIP/postal ranges, and unsupported regions.
• Preview, publish, roll back, and restore validation configs.
