Air Waybill (AWB): Air Cargo Tracking, Number Format & 11-Digit Guide (2026)
An Air Waybill (AWB) is a non-negotiable international air transport document issued by an airline or IATA freight forwarder. It acts as a receipt of goods, evidence of the contract of carriage, customs declaration document, and carrier liability contract capped under the Montreal Convention (22 SDR/kg).

Understanding AWB: Comprehensive Technical Analysis
Operational mechanism and commercial application in international freight
The Air Waybill (AWB) governs international air freight movements departing Turkish aviation hubs. Issued under International Air Transport Association (IATA) regulations, an AWB carries a standard 11-digit numbering format (the first 3 digits represent the airline prefix, e.g., 235 for Turkish Cargo). Crucially, unlike an ocean Bill of Lading, an Air Waybill is strictly non-negotiable and NEVER acts as a document of title: goods are delivered directly to the named consignee upon customs clearance. Carrier liability is governed by the 1999 Montreal Convention, capping compensation at 22 Special Drawing Rights (SDR) per kilogram (~$30/kg) for cargo loss or damage.
What is an Air Waybill (AWB)? Definition & Legal Function
An Air Waybill (AWB) is a non-negotiable international air transport document issued by an operating airline or authorized IATA freight forwarder. It acts as an official receipt of goods, evidence of the contract of carriage, customs clearance manifest, and freight invoice. Unlike a maritime Bill of Lading, an Air Waybill is strictly non-negotiable and does NOT serve as a document of title; goods are released directly to the named consignee upon customs clearance. Carrier liability is strictly capped at 22 SDR per kilogram (~$30/kg) under the Montreal Convention.
11-Digit AWB Number Structure & Check-Digit Verification
All standard international IATA air waybills follow a rigid 11-digit numbering format (e.g., 235-12345675). This number enables automated global flight tracking, electronic e-AWB transmission, and customs reporting:
- 1. Airline Prefix (3 Digits)
- The official numeric identifier assigned by IATA to the operating carrier (e.g., 235 for Turkish Cargo, 020 for Lufthansa Cargo).
- 2. Cargo Serial Number (7 Digits)
- A unique sequential 7-digit identification number allocated by the issuing airline for the specific consignment.
- 3. Check Digit / Modulo 7 (1 Digit)
- Calculated as the remainder when the 7-digit serial number is divided by 7 (Serial mod 7). Validates document integrity and prevents typographical errors.

Istanbul Airport (IST) Mega Cargo Hub Operations
Authoritative operational insights under Turkish Customs Law No. 4458 & border regimes
With Turkish Cargo operating one of the world's fastest-growing air cargo networks from Istanbul Airport (IST / LTFM Mega Cargo City) and Sabiha Gökçen (SAW), AWB documentation moves almost entirely electronically via IATA e-AWB standards. Brosan Lojistik coordinates secure airport transfer, x-ray security screening, and bonded warehouse customs dispatch within 4 to 8 hours of factory pickup.
Key Turkish Export Compliance Points
- •Volumetric ratio for air cargo: 1 CBM = 167 kg (1:6000 ratio). Chargeable weight is the higher of gross weight or volumetric weight.
- •Lithium batteries, perfumes, chemicals, and pharmaceuticals require specialized IATA DGR declarations before AWB execution.
- •Direct tracking available 24/7 via airline 11-digit AWB numbers.
Common Shipper Mistakes to Avoid
- ⚠️Underestimating volumetric chargeable weight: bulky garments or foam products billed at 167 kg/m³ instead of low physical scale weight.
- ⚠️Undeclared hazardous materials (such as lithium battery devices or chemical aerosols), resulting in severe aviation security fines and cargo rejection.
- ⚠️Consignee details not matching the destination customs import declaration, delaying release at European and US airports.

Frequently Asked Questions for AWB
Direct answers to high-intent questions on responsibilities, costs, and risk
Q1:What is an Air Waybill (AWB) and how does its 11-digit structure work?
An Air Waybill (AWB) is a non-negotiable air cargo consignment note and carriage contract. It features a standardized 11-digit structure: a 3-digit airline prefix (e.g., 235 for Turkish Cargo, 020 for Lufthansa Cargo), a 7-digit shipment serial number, and a 1-digit check digit calculated via the Modulo 7 algorithm to ensure verification and prevent typographical errors.
Q2:Can an Air Waybill be negotiated or transferred like an ocean Bill of Lading?
No. An Air Waybill is strictly non-negotiable. It does not carry legal title to the cargo; the airline will release the goods directly to the consignee named on the AWB once customs clearance is completed.
Q3:How is chargeable weight calculated on an Air Waybill?
Air cargo chargeable weight is calculated using the IATA standard ratio of 1:6000 (Length cm × Width cm × Height cm / 6000 = volumetric kg). The airline bills whichever is greater between physical scale weight and volumetric weight.
Q4:What is the carrier liability limit under an Air Waybill?
Under the Montreal Convention 1999 (as amended), airline liability is capped at 22 SDR (Special Drawing Rights) per gross kilogram of damaged weight, roughly $28–$30 per kg.
Q5:What airline uses AWB prefix 235 and how do you track Turkish Air Cargo?
AWB prefix 235 is the official 3-digit IATA airline prefix assigned to Turkish Airlines (Turkish Cargo). To track a Turkish Air Cargo consignment by 11-digit AWB number, enter prefix 235 followed by the 8-digit tracking serial (e.g., 235-XXXXXXXX) into the Turkish Cargo online tracking portal or Brosan Lojistik's air freight tracking system for real-time flight departure, customs clearance, and destination arrival status.
