Address Validation iO

Address Validation iO helps prevent shipping errors and failed deliveries by validating customer addresses in real-time. During checkout, the app uses smart autocomplete to catch common issues like missing house numbers, invalid ZIP codes, and PO box restrictions. Customers receive immediate notifications to fix address problems, reducing returns and customer support requests. The address validation system works across all Shopify themes and plans, with an easy installation process that requires no coding skills. Store owners can customize address validation prompts to match their brand style and preferred language. The app is fully GDPR and CCPA compliant, making it a reliable solution for accurate order fulfillment and improved delivery success rates.
