PostGrid Address Verification

PostGrid Address Verification helps reduce failed deliveries by providing accurate, standardized address suggestions at checkout. The app verifies address accuracy, completeness, and deliverability using USPS CASS and Canada SERP postal service standards, helping prevent return-to-sender errors. Customers receive real-time address suggestions during checkout and get notified when a verified address is available. Merchants benefit from reliable address data and can customize filters to block non-deliverable addresses or PO boxes. The app includes usage reporting and address rules to maintain clean customer data and improve delivery success rates.
