AWB Validator

"Tracking returns nothing" is usually a typo, not a missing shipment. Paste the air waybill number and this checks the digit that is meant to catch exactly that — then tells you which airline issued it.

3-digit airline prefix + 8-digit serial. Separators are ignored, so paste it however it arrived.

Anatomy of an air waybill number

   └───────────────────── airline prefix (IATA numeric code)

Eleven digits, always. The prefix identifies the carrier, the serial identifies the consignment, and the check digit exists so a transcription error is caught before anybody phones the airline. The sample above is generated by the same code that validates your input, so it is always self-consistent.

Prefixes we recognise

40+ airlines. Verify a prefix against the carrier's own documentation before issuing a waybill against it.

Frequently asked

How is the AWB check digit calculated?

Take the 7-digit serial that follows the 3-digit airline prefix, divide it by 7, and keep the remainder. That remainder is the 11th digit. For serial 1234567 the remainder is 5, so the full number is 235-12345675.

My AWB fails the check. Is the shipment lost?

Almost certainly not — a failing check digit means the number is wrong, not the cargo. Two digits transposed while being copied from an email is the usual cause. Re-read the number from the waybill itself before escalating to the airline.

What is the difference between a master and a house air waybill?

The master AWB (MAWB) is issued by the airline and covers the flight legs; it is the 11-digit number this tool checks. A house AWB (HAWB) is issued by a forwarder for one shipment inside a consolidation and uses the forwarder’s own numbering, so it has no standard check digit.

Can I tell which airline issued an AWB?

Yes — the first three digits are the airline’s IATA numeric code. This tool resolves the prefix against our registry of 40+ airlines. An unrecognised prefix means we do not cover that carrier yet, not that the number is invalid.
