AddressGuard Address Validator

AddressGuard Address Validator adds real-time, carrier-validated address verification to your Shopify checkout. This address validator checks addresses against global and local carriers to prevent failed deliveries and reduce costly carrier correction fees that can exceed $25 per order. The app uses AI Autocorrection to automatically fix common address errors like "Rd" to "Road" before orders ship. You can create custom rules to block PO Boxes, require apartment numbers, or flag addresses with special characters. Plus users can replace Shopify's Google Autocomplete with AddressGuard's carrier-validated Autocomplete. Built-in email and phone verification improves overall data quality. The validator works seamlessly with Shop Pay, Apple Pay, Google Pay, and PayPal express checkouts. Hold undeliverable orders before they reach your 3PL and add order tags to match your fulfillment workflows. No coding required - install takes just 5 minutes and works with all Shopify plans.
