What is an NDR (Non-Delivery Report) in shipping?

NDR (Non-Delivery Report) is a shipping update generated when a courier partner is unable to successfully deliver a shipment to the customer. It includes the reason for delivery failure, such as customer unavailability, incorrect address, unreachable phone number, refused delivery, incomplete address, or delivery delay. NDR helps sellers identify failed delivery attempts and take corrective action quickly.

In eCommerce shipping, NDR management is important because failed deliveries can increase Return-to-Origin (RTO) losses, delay order fulfillment, and affect customer satisfaction. Once an NDR is generated, sellers can contact customers, confirm delivery details, reschedule delivery attempts, or update address information to improve delivery success rates.

Shipping aggregators and logistics platforms provide NDR dashboards and automated notifications to help businesses manage delivery exceptions efficiently. Proper NDR handling reduces failed deliveries, improves operational efficiency, and increases successful order fulfillment. For online sellers handling large shipment volumes, effective NDR management plays a major role in reducing shipping losses and improving customer experience.
