Melissa Address Validation

Melissa Address Validation helps prevent shipping errors and checkout friction for your Shopify store. This app validates and corrects customer addresses across 240+ countries, ensuring successful deliveries every time. It's certified compliant with USPS CASS, SERP Canada, and Royal Mail UK postal standards. The app offers address autocomplete that fills in missing fields and suggests valid alternatives during checkout. It verifies sub-premise data including suites, apartments, floors, and offices for accurate delivery. Unlike other solutions, Melissa supports native language rules, express checkout validation, and international postal standards in one integrated app. Advanced parsing and formatting precision help reduce returns while improving the customer experience at checkout.
