See every featureAutomate U.S. shipping address validation after checkout to verify addresses before fulfillment. Detect invalid or incomplete addresses, including missing apartment numbers and P.O. Boxes. Automatically notify customers to confirm or correct shipping information, then update Shopify orders. Apply address verification tags, customize email notifications, and manage exceptions.
Some 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.
