About PostGrid Address Verification

The app checks accuracy, completeness, and deliverability using postal service standards, helping reduce issues such as return-to-sender errors. Customers can choose from real-time suggestions during checkout and are notified when a verified address is available. Merchants maintain reliable address data and can set rules to block non-deliverable addresses or PO boxes.
