Frequently asked questions

How AWB numbers and check digits work.

Q. How is the AWB check digit calculated?

Take the 7-digit serial number (the digits after the 3-digit airline prefix), divide it by 7 and use the remainder (0 to 6) as the 8th digit. For example 1234567 ÷ 7 leaves 5, so the AWB is 176-12345675.

Q. What is the format of an air waybill number?

11 digits: a 3-digit airline prefix, a 7-digit serial and a 1-digit check digit, usually written 176-1234 5675.

Q. Why is the check digit never 7, 8 or 9?

It's the remainder after dividing by 7, so it can only be 0 to 6. Every serial in your range still gets exactly one AWB number.

Q. Can I enter the start number with the check digit?

Yes. Type 7 digits (serial only) or all 8 digits. If you type 8, the tool checks that the last digit is correct before generating.

Q. Is my AWB stock sent anywhere?

No. The series is generated in your browser and never uploaded.
