NDR Management: The Complete Guide for E-commerce Sellers

A Non-Delivery Report (NDR) is generated whenever a courier attempts delivery and fails.

How a business responds to an NDR — within hours, not days — is often the single biggest factor separating a healthy RTO rate from a damaging one.

The NDR Lifecycle

A typical NDR journey looks like this: Order Placed → Delivery Attempt → NDR Raised → Customer Contacted → Reattempt Scheduled → Delivered or Marked RTO. Each stage is a point where proactive management can change the outcome.

Common NDR Reason Codes

• Customer not available / not reachable
• Customer requested reschedule
• COD amount not ready / refused
• Address not found or incomplete
• Out of delivery area
• Customer refused the order

Building a Proactive NDR Process

The single biggest improvement most sellers can make is contacting the customer within a few hours of an NDR being raised — via SMS, WhatsApp, or a quick call — rather than waiting for the courier's automatic reattempt cycle. A customer who confirms a new delivery slot converts at a far higher rate than one who is simply re-attempted without contact.

Address Intelligence and Proactive Intervention

A growing number of Indian logistics platforms are investing in address-quality tools that flag likely-to-fail addresses before the first delivery attempt, not after. AI-based address scoring — checking for landmark presence, pincode-locality mismatch, or historical failure at that address — is becoming an important layer of NDR prevention, catching problems before they ever generate a failed attempt.

Turning NDR Data Into Long-Term Improvement

Beyond individual order recovery, NDR data is a goldmine for structural fixes: which couriers have the highest NDR-to-delivery conversion in a zone, which product categories see the most refusals, and which checkout flows produce the most address errors.
