About the modlet: Block PO Box & Lockers

This app blocks PO boxes and lockers at checkout to prevent failed deliveries and expensive carrier return fees. Built directly into Shopify Checkout, it physically stops customers from completing orders to restricted addresses, ensuring 100% reliable blocking that can't be bypassed. The app protects your shipping margins with global PO box blocking and includes a built-in address simulator to test your rules safely. Pro features let you create custom error messages for your brand and local languages, plus set specific exception rules for different shipping methods, regions, or products. Built by a veteran cloud architect with efficient infrastructure, the app offers a generous free tier to help new stores grow. Upgrade to Pro as your order volume increases or when you need granular shipping rules and customization options.
