What Is an AWB Number? Definition and Origin
The term AWB originally comes from the aviation and freight industry, where an Air Waybill was a non-negotiable contract document accompanying cargo on an aircraft. It contained the shipper's details, the consignee's details, the origin, the destination, and a unique reference number. Over decades, as logistics networks expanded to include road, rail, and last-mile courier delivery, the term AWB — and especially the AWB number — was adopted across all shipping modes, not just air freight.
In the context of Indian e-commerce, an AWB number is simply the unique tracking ID assigned to a single shipment. It has no standard length or format across the industry — each courier partner designs its own. What matters is that within a courier's system, every AWB number is distinct, which means the status, location, delivery attempts, and exception history of any parcel can be retrieved instantly by querying that number.
Think of the AWB number as the shipment's digital identity card. Without it, a parcel is anonymous inside a logistics network that processes millions of packets daily. With it, every warehouse scan, transit hub movement, and delivery attempt is logged against a single, traceable reference — making accountability possible for sellers, buyers, and courier partners alike.
How AWB Numbers Work Across Major Indian Couriers
Each major courier partner in India maintains its own AWB number format, and sellers working across multiple platforms will encounter several of them.
Blue Dart AWB numbers are typically numeric and can be tracked on the Blue Dart website or through third-party dashboards. Blue Dart's system is well-regarded for granular scan updates, making AWB-level tracking highly reliable for high-value or time-sensitive shipments.
Delhivery issues alphanumeric AWB numbers that are accepted on its tracking portal. Delhivery's network covers a wide pin code range, and its AWB system logs both forward and reverse shipment events under the same reference framework.
DTDC assigns numeric AWB numbers prefixed by a zone or origin code. Sellers shipping through DTDC can use the AWB number on DTDC's website or app to get real-time transit status.
India Post Speed Post uses a format that follows the Universal Postal Union (UPU) standard — an alphanumeric code beginning with two letters, followed by digits, and ending with 'IN' for domestic shipments. This format enables tracking on the India Post portal.
Across all of these, the core function is identical: the AWB number is the lookup key that retrieves a shipment's complete event history. Sellers should store AWB numbers against every order ID in their records, as courier customer care teams cannot assist without it.
How Shiprocket Assigns and Manages AWB Numbers
For sellers using Shiprocket, AWB number management is largely automated, which removes a significant manual burden. When a seller creates a shipment on Shiprocket and selects a courier partner — either manually or via the AI-powered courier recommendation engine — Shiprocket's system communicates with the courier's API and retrieves a unique AWB number for that specific shipment.
This AWB number then appears on the shipping label that is printed and affixed to the package. It also populates the seller's Shiprocket dashboard, where it is linked to the original order ID. This means sellers do not need to log into individual courier portals to track shipments — all AWB-level events from the courier's scan network are pulled into the Shiprocket dashboard in one place.
For reverse logistics, when a return is initiated, Shiprocket generates a separate AWB number for the return shipment, keeping forward and reverse journeys traceable independently. Sellers can also share the AWB number directly with their buyers via Shiprocket's automated branded tracking page and notification system, so buyers can self-serve their tracking queries rather than contacting support.
One practical tip: if a shipment status appears stuck on the Shiprocket dashboard, the first diagnostic step is to cross-check the same AWB number on the respective courier's own portal to identify whether the delay is a scan lag or a genuine logistics exception.
Common AWB Number Mistakes That Cause Shipment Problems
Even though AWB numbers are generated automatically in modern platforms, several mistakes at the seller's end can cause serious downstream problems.
The most damaging error is not communicating the AWB number to the buyer. When buyers do not receive a tracking reference, they raise disputes, initiate chargebacks, or simply refuse delivery — all of which drive up RTO (Return-to-Origin) rates and erode seller metrics on marketplaces.
Printing the wrong AWB number on a label — possible when labels are manually prepared or when multiple shipments are processed in a batch — means a package carries an identifier that does not match the courier's booking record. This leads to 'unmanifested shipment' exceptions where the courier's system cannot locate the parcel record, causing delays or misrouting.
Another frequent mistake is sharing an old AWB number for a re-attempted or re-booked shipment. If a first booking is cancelled and the order is re-shipped, a new AWB number is generated. Sharing the old one with the buyer or marketplace will show incorrect or stale tracking data, causing unnecessary escalations.
Finally, sellers sometimes confuse the AWB number with the order ID when filing courier complaints. These are different references — the order ID is internal to the seller's system or marketplace, while the AWB number is the courier's reference. Always use the AWB number when contacting courier customer care or raising a lost-shipment claim.
How to Use AWB Numbers to Reduce RTO and Improve Delivery Experience
An AWB number is not just a tracking tool — used proactively, it is a delivery performance lever. Sellers who build AWB-based workflows into their operations consistently see better delivery rates and fewer escalations.
The first step is immediate AWB sharing. As soon as a shipment is booked and an AWB number is assigned, trigger an automated notification to the buyer — via SMS, WhatsApp, or email — with the tracking link. Buyers who can self-track a shipment are far less likely to raise a non-delivery dispute or refuse the parcel.
The second step is proactive exception monitoring. Use your shipping dashboard to flag AWB numbers where the shipment has not received a scan within an expected window. Early intervention — contacting the courier's hub or raising a ticket — prevents exceptions from compounding into full RTOs.
Third, for high-value orders, cross-check the AWB number on the courier's native portal at each major transit milestone. Dashboards aggregate data via API and may have a short lag; the courier's own system will always have the most current scan.
Finally, when a shipment is marked undelivered or RTO-initiated, use the AWB number to pull the full delivery attempt log. This log tells you exactly when delivery was attempted, what reason was given, and whether a re-attempt is possible — information that is essential for deciding whether to call the buyer and salvage the delivery before the parcel returns.
