How to read a Croatia Airlines(OU) air waybill number

831-51989070 example only — not a real shipment

Air waybill numbers are 11 digits, usually printed like 831-51989070. The first three digits are the IATA airline prefix — 831 is Croatia Airlines(OU)’s — and the remaining eight are the serial, where the last digit is a check digit (the first seven digits modulo 7).

One AWB covers the whole consignment (there is no per-piece number), and unlike container numbers, AWB serials are recycled by airlines after roughly a year — so a very old number can show someone else’s shipment.

If your Croatia Airlines(OU) tracking isn’t working

1. 1 Check the number format first

   An air waybill is 11 digits — a 3-digit airline prefix and an 8-digit serial, e.g. 831-51989070. Enter it with or without the dash, but don’t drop leading zeros from the serial.

2. 2 Make sure the number was issued by this carrier

   If your serial doesn’t start with 831, the AWB was issued by a different airline or a freight forwarder (a “house” AWB). Track house AWBs with the forwarder; the airline only sees its own “master” AWB.

3. 3 Too early or too late

   New shipments can take a little while to appear — most carriers only start returning results once the air waybill is in their system after export gate-in or acceptance. Long-delivered shipments drop out too: tracking data is usually purged weeks or months after delivery.

4. 4 Paste carefully on Croatia Airlines(OU)’s page

   Croatia Airlines(OU) asks you to type the number on its own page, so paste it exactly — no spaces before or after, and no extra characters picked up from an email. If the page shows a security check, complete it and search again.

5. 5 Still nothing?

   Your booking agent or Croatia Airlines(OU)’s customer service can look the shipment up internally — have the air waybill number and the issuing office or booking reference handy when you ask.
