What Is an Air Waybill (AWB)?

What is an air waybill?

An air waybill (AWB) is the contract and receipt for a shipment moving by air. Think of it as the cargo version of a ticket: it says who handed the goods to the carrier, where they’re going, and under which airline’s responsibility they’re moving. It matters because banks, customs brokers, and warehouses all refer to the AWB when they need to prove what was shipped, who owns it in transit, and which flight routing applies.

You’ll see the term written as air waybill, airway bill, or just AWB — they mean the same thing in everyday use. The unique AWB number printed on that document is what you type into a tracker when you want status updates.

MAWB vs HAWB

Not every “AWB” you see is the same kind of document. A Master Air Waybill (MAWB) is issued by the airline and covers the full contract between the carrier and the party that booked the uplift — often a freight forwarder. A House Air Waybill (HAWB) is issued by the forwarder to you, the actual shipper or consignee, and describes your piece of a larger consolidated shipment.

For tracking on airline systems, you usually want the MAWB (or the number the airline recognizes as the master). If you only have a house number, your forwarder can tie it to the master. Our AWB vs tracking number page goes deeper when a portal asks for something that doesn’t look like a standard AWB.

What information does an AWB contain?

Layouts vary by carrier and whether the document is paper or electronic, but most AWBs carry the same core story:

• Shipper and consignee — names, addresses, and contact details
• Origin and destination — airports or cities, sometimes with routing via hubs
• Pieces and weight — carton count, gross weight, and often chargeable weight
• Description of goods — enough detail for handling and customs
• Charges and terms — prepaid or collect, and references for billing

Together, those fields explain what moved, who is responsible at each step, and how the shipment should be handled on the ground.

How to read an AWB number

The familiar eleven-digit format is an IATA standard: a three-digit airline prefix (who operates or issues the waybill) followed by an eight-digit serial. The last digit is a check digit — a checksum that helps systems catch transposed or mistyped numbers.

People often show it with a hyphen, like 176-12345675, but trackers accept the digits run together. Prefixes are assigned to carriers; you’ll find many of them on our supported airlines list. For a full breakdown of positions and validation, see AWB number format.

How to track your AWB

Once you have the eleven digits, tracking is simple: open airwaybilltracker.com, paste the number, and follow the link to the carrier’s official tool. That keeps you on the source of truth for scans, delays, and delivery — especially useful when a forwarder’s email trail is one step behind the airline.

Popular airline track pages you can bookmark include Emirates SkyCargo, Lufthansa Cargo, and FedEx. Browse the full directory on airlines.html if you’re not sure which carrier matches your prefix, or look up any 3-digit code in the AWB prefix directory.
