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. Configure custom block messages and enable or disable protection with one click.

• Real-time address validation catches PO Boxes before orders enter your system
• Works automatically in the background, no manual order review required
• Compatible with all Shopify themes and checkout configurations
