The Air Waybill comprises three components
- the Airline Code Number which is the issuing carrier's three-digit IATA airline code
- a seven digit serial number
- a check digit
The check digit is based on an unweighted modulus 7 calculation. The seven-digit serial number is simply divided by 7 and the resulting remainder is the check digit.
Example
Serial number = 1234567
1. Divide serial number by 7 = 176366
2. Remainder = 5 = check digit
3. Air Waybill = Airline Code Number + 1234567
