About PO Box Blocker Pro
PO Box Blocker Pro checks each shipping address at checkout and blocks addresses you can't deliver to before the order is placed. Block PO boxes, parcel lockers, locked bags, private bags and APO/FPO addresses, or restrict delivery by country, state, city or postal code. Allow chosen products, variants or collections to bypass the rules, set a custom checkout message, and test any address before going live. Works on standard checkout and Shop Pay across all Shopify plans. No theme edits needed.
