Reserved, never typed
A probill is reserved from a shared sequence the moment the booking sheet opens, shown read-only and unique within the company, so two people booking at once cannot collide.
Every plan
Probill — PRO number
A probill — often called a PRO number — is the carrier's own reference number for a shipment: the number printed on its paperwork that drivers, customers and the office quote when they talk about one load.
Also called: PRO number, pro bill, freight bill number
- Who deals with it
- Issued when the load is created; quoted by drivers, customers and billing.
- When it shows up
- At booking, before any paperwork is produced.
- What usually goes wrong
- Duplicates — two people creating loads at once, or a numbering scheme kept in a spreadsheet — and every document downstream inherits the collision.
Probill, explained
Every load needs a number people can say out loud. The probill is that number: issued by the carrier, unique to one shipment, and carried on the bill of lading, the delivery paperwork and the invoice so everyone is talking about the same freight. It is separate from the customer's or broker's own load number, which often travels alongside it.
It matters more than it looks. On the northern border the probill commonly forms the unique part of the PAPS number, after the carrier's SCAC — so a duplicate is not just an office nuisance. Two shipments sharing one identity can end up sharing a customs reference, and every document downstream inherits the collision.
How Lanexa handles it
This lives mainly in Loads, where 157 catalogued capabilities are live. Each item says which plan it is on.
One sequence for a group
Companies in a group share one probill sequence, so a number never repeats across sister companies.
Enterprise
The root of the customs numbers
Shipment and cargo control numbers are built from your carrier codes plus the probill, so the paperwork and the border reference agree.
Start and up
Open a load by its number
P000123, p123 or just 123 — the same load opens from a deep link anywhere in the product, and every screen shows the probill first, then the load number.

Questions about Probill — PRO number
What is a probill?
A probill — often called a PRO number — is the carrier's own reference number for a shipment: the number printed on its paperwork that drivers, customers and the office quote when they talk about one load.
Is a probill the same as a load number?
Not necessarily. The probill is the carrier's own reference; a load number is often the customer's or broker's reference for the same freight.
Lanexa keeps both, shows the probill first, and refuses a load number reused for the same customer.
Why do probill numbers sometimes skip in Lanexa?
A probill is reserved when the booking sheet opens, so a form that is abandoned uses up its number.
That is deliberate: a number, once issued, is never handed to a different load.
How does a probill relate to PARS and PAPS numbers?
A PAPS number is the carrier's SCAC followed by a unique reference, and a PARS number is the CBSA carrier code followed by one.
The probill is the usual choice for that unique reference, which is why it has to be unique.
