PAPS vs PARS: Which Border Code Does Your LTL Freight Need?
PAPS or PARS for LTL freight shipping? This guide breaks down the key differences so Canadian SME shippers can choose the right border code with confidence.
By Max Gravel · 5 min read ·
Quick Answer#
For LTL freight entering the United States from Canada, the carrier normally assigns a PAPS number for U.S. pre-arrival processing. PARS applies when freight is entering Canada, so confirm the direction of travel, carrier instructions, and broker submission before pickup.
Introduction#
LTL freight moving from Quebec or Ontario into the U.S. needs a PAPS reference, not a PARS reference, when it requires U.S. customs pre-arrival clearance. The code must match the carrier’s manifest and the broker’s entry documents exactly, or the shipment can be held at the border. This is manageable when responsibilities are confirmed before freight leaves the dock. A late correction can turn an ordinary pallet pickup into a missed delivery commitment.
Key Takeaways:
PAPS is used for freight entering the United States by highway.
PARS is used for commercial freight entering Canada.
Carrier, broker, and shipper details must match exactly.
How LTL freight border codes work#
Border codes connect a physical shipment to the electronic pre-arrival filing reviewed by customs authorities. For cross-border LTL shipping from Montreal, the first practical question is simple: which country is the truck entering? The code follows that inbound border process, while the broker prepares the customs release using the commercial documents supplied by the shipper.
PAPS for freight entering the United States#
PAPS, or Pre-Arrival Processing System, is the U.S. shipment reference assigned by the carrier for freight requiring pre-arrival clearance. The carrier’s PAPS label, ACE eManifest, and broker submission must carry the same identifier, and cargo data must reach CBP one hour before arrival at the first U.S. port, or 30 minutes for qualifying CTPAT shipments.
Direction: Use PAPS for highway freight entering the United States.
Issuer: The carrier assigns the PAPS shipment number.
Carrier ID: PAPS uses a four-letter SCAC.
Matching: Labels and broker records require identical numbers.
PARS for freight entering Canada#
PARS, or Pre-Arrival Review System, is Canada’s comparable process for commercial goods arriving by highway. The carrier sends the invoice or cross-border freight documents to the broker at least two hours before arrival in Canada, and the cargo control number must include PARS in the barcode when PARS appears within that number. CBSA bar-coded labels are required for the Canadian highway process.
PAPS vs PARS for LTL shipping Canada to USA customs compliance#
PAPS and PARS are not interchangeable labels, even though both support advance review of commercial cargo. The table below shows the operational distinction that matters when you book LTL shipping across the Canada-U.S. border.
Compare the code by the shipment’s destination country#
Use the code associated with the country of entry, then verify the carrier’s reference before documents go to the broker. This distinction matters for businesses LTL customs clearance because a border crossing does not correct a mismatched cargo reference.
Item | PAPS | PARS |
|---|---|---|
Country entered | United States | Canada |
Carrier identifier | Four-letter SCAC | Carrier code plus cargo control number |
Advance filing | ACE truck manifest | CBSA pre-arrival review |
Document timing | One hour before first U.S. arrival | Broker receives documents two hours before Canadian arrival |
The deciding factor is the border the truck is entering; the carrier must also be authorized and appropriately bonded for the country of entry.
Prevent documentation failures before pickup#
Start by giving the carrier and broker the same shipper, consignee, commodity, port, and estimated arrival details. This reduces customs documentation errors, particularly when shipping 1 to 8 pallets LTL and warehouse staff are managing several outbound orders at once. A broker also needs a reachable carrier contact if a filing needs clarification.
For a Montreal manufacturer delivering pallets to New York, obtain the PAPS number from the carrier, place it on the broker instructions, and ensure it matches the shipment paperwork. BorderConnect states that the related eManifest shipment control number must be identical to the bill or in-bond record where applicable. For U.S.-origin freight delivered to Ontario, obtain the PARS cargo reference instead and send documentation early enough for Canadian review. Maintaining shipment control number consistency is the operational safeguard in either direction.
Use direct carrier coordination for cross-border moves#
