How to read a Perimeter air waybill number

632-52136000 example only — not a real shipment

Air waybill numbers are 11 digits, usually printed like 632-52136000. The first three digits are the IATA airline prefix — 632 is Perimeter’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 Perimeter 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. 632-52136000. 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 632, 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

   Timing matters: a number that was only just issued may not show results yet, and carriers remove old shipments from public tracking a few weeks after delivery. If the shipment is very new or long delivered, an empty result doesn’t mean the number is wrong.

4. 4 Paste carefully on Perimeter’s page

   Perimeter 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?

   Contact whoever sold you the freight service (your forwarder, broker, or Perimeter directly) with the air waybill number and the booking reference — they can see internal status that public tracking doesn’t show.

Why does the Perimeter page open without my number filled in?

Perimeter asks everyone to enter the number on its own page (it has a security check), so it can’t be filled in ahead of time. We bring you to the right page — just paste your number there.

What if my number doesn’t start with 632?

Then it probably wasn’t issued by Perimeter — shipments booked through a freight forwarder or partner carrier often travel under another company’s air waybill number. Paste the number on our homepage and we’ll suggest the right airline, or check your shipping paperwork for who issued it.

Is this Perimeter’s official tracking site?

No — this is a free, independent tool that brings every carrier’s tracking together in one place. When you track here you end up on Perimeter’s own page, so everything you see comes straight from Perimeter. We never see or store your shipment details.
