Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureSome carriers (e.g. Fedex) charge extra fees or refuse delivery to PO Boxes. SafeShip validates customer addresses at checkout and blocks orders with PO Box addresses before payment. This prevents failed deliveries, avoids carrier surcharges, and saves you from manually reviewing orders. Customers see a clear message explaining why their address cannot be used, reducing support requests.
Many couriers can't deliver to PO boxes or need a recipient phone number to dispatch a parcel. Orders with these addresses lead to returned parcels, fulfillment delays and extra support work. ShipShield checks each shipping address in Shopify checkout and asks the buyer for a street address or phone number before the order is placed.
