If you are involved in cross-border trucking between the US and Canada, you have almost certainly encountered the terms PARS and PAPS. These two tracking systems are fundamental to how customs brokers and border agencies process commercial shipments, yet many drivers and even some dispatchers confuse the two. This guide breaks down the differences, explains how each system works, and shows why real-time tracking matters.
What Is PARS?
PARS stands for Pre-Arrival Review System and is used by the Canada Border Services Agency (CBSA) for goods entering Canada. When a customs broker prepares the entry documentation for a shipment headed into Canada, they generate a PARS barcode -- a unique number that links the cargo to the broker's customs entry.
Here is how PARS tracking works in practice:
1. The customs broker creates the entry and generates a PARS barcode number
2. The broker transmits the entry data to the CBSA electronically
3. The PARS barcode is affixed to the cargo paperwork that travels with the driver
4. When the driver arrives at the Canadian border, they present the PARS barcode
5. The CBSA officer scans the barcode, which pulls up the pre-filed entry and the eManifest data
6. If everything matches and the entry is cleared, the driver proceeds
The PARS number is typically in the format of a letter followed by digits, and it must exactly match what the broker transmitted to the CBSA.
What Is PAPS?
PAPS stands for Pre-Arrival Processing System and serves the same basic function as PARS, but for goods entering the United States. It is managed by US Customs and Border Protection (CBP).
The PAPS tracking process mirrors PARS:
1. The US customs broker creates the entry and generates a PAPS barcode number
2. The broker transmits the entry data to CBP
3. The PAPS barcode travels with the shipment paperwork
4. At the US port of entry, the driver presents the PAPS barcode
5. CBP scans the barcode to pull up the entry and match it against the ACE eManifest
6. The driver is cleared to proceed once everything checks out
PAPS numbers follow CBP's format and are tied to the broker's filer code.
Key Differences Between PARS and PAPS
| | PARS | PAPS |
|---|---|---|
| Direction | Goods entering Canada | Goods entering the US |
| Agency | CBSA | CBP |
| Linked manifest | ACI eManifest | ACE eManifest |
| Barcode format | CBSA format | CBP filer code format |
| Filing system | ACI/EDI | ACE portal |
The core concept is identical -- both systems let the border agency pre-process a shipment before the truck arrives. The difference is simply which country and which agency is involved.
How PARS and PAPS Work Together
For a round-trip cross-border haul, a carrier may deal with both systems on the same trip. For example:
- A Canadian carrier picks up a load in Toronto heading to Chicago. The US customs broker generates a PAPS barcode for the southbound US entry.
- The same carrier picks up a return load in Chicago heading back to Toronto. A Canadian customs broker generates a PARS barcode for the northbound Canadian entry.
Both barcodes must be accurate, transmitted in advance, and presented at the respective borders. A mismatch on either side causes delays.
Why Real-Time PARS and PAPS Tracking Matters
One of the most common causes of border delays is arriving at the port before the customs broker's entry has been processed. If the broker has not yet transmitted the data, or if the entry is still under review, the driver sits and waits.
Real-time tracking of PARS and PAPS status eliminates this guesswork. When you can see whether an entry has been received, is under review, or has been cleared, you can:
- Time your arrival to avoid sitting at the border waiting for clearance
- Catch problems early -- if an entry is rejected, you know before the driver reaches the port
- Coordinate with brokers -- instead of calling to ask "is it cleared yet?", you can see the status yourself
- Reduce detention charges -- faster crossings mean drivers spend less time waiting and more time earning
