AiVerify Address Validator

Catch bad shipping addresses before and after checkout — automatically. Address Validator checks shipping addresses at checkout and fixes small mistakes automatically — before orders get marked as delayed or undeliverable. Built-in checks catch PO boxes, missing house numbers, and invalid postal codes in every country. Advanced verification adds real-time address correction: customers see and approve any change on their order confirmation page. Full verification covers 40 countries; built-in checks work everywhere.
