In plain English
It is usually printed on a pro label stuck to the freight and appears on the paperwork and on the carrier’s tracking page. Each carrier uses its own format.
It is different from the BOL number the shipper assigns. You will often be asked for both.
Why it matters when you ship
The pro number is what you give the carrier to track, to book a delivery appointment or to file a claim. Keep it with the BOL.
Example
A shipper receives pro number 123456789 from the carrier after pickup and uses it on the carrier’s website to track the shipment.
