A meaningful share of failed deliveries trace back to address errors at checkout. Shipping Address Validator checks addresses at checkout and again on the Thank You page after the order is placed, flagging anything a carrier could fail to deliver. Customers get a one-click suggested correction at either point. Merchants set how strict the checkout check is (suggest, warn, or block); the post-checkout check runs automatically as a safety net regardless.

• Real-time carrier-verified address checking at checkout and again post-checkout
• Automatic order tagging and validation history for merchants
• One-click address correction for customers at checkout and post checkout
