Your first cross-border load can feel like a wall of acronyms: SCAC, PARS, PAPS, ACE, ACI, CARM. It is not as complicated as it looks once you see the pieces in order. At its core, a cross-border load is a normal load with three extra jobs layered on top: proving who your company is to two governments, telling each border agency what is coming before you arrive, and giving the driver the right documents to walk through the door.
If you already run domestic freight cleanly, you have most of the discipline you need. This guide walks a first-time US or Canadian carrier through the whole sequence, from getting authority in both countries to the moment your driver rolls up to the primary inspection booth.
Take it one step at a time. Miss a step and you get turned around at the line; do them in order and your first crossing is quieter than you expect.
What operating authority do I need on each side of the border?
You need active operating authority in whichever country you are hauling into, not just your home country. A Canadian carrier delivering into the US and a US carrier delivering into Canada each register with the other side's regulator before their first load.
To run into the United States, you register with the Federal Motor Carrier Safety Administration (FMCSA). The FMCSA issues operating authority identified as an MC, MX, or FF number, and it dictates the type of operation you can run and the cargo you can carry. Alongside authority you need a USDOT number and, for cross-border trips, the truck and driver information that CBP will expect.
To run into Canada, a US carrier registers with the Canada Border Services Agency (CBSA) for a carrier code (covered below) and complies with the safety and licensing rules of the provinces it operates in. There is no single federal "authority" the way the US has an MC number; provincial and CBSA registration together do the job.
The practical takeaway: do not assume your domestic paperwork carries you across. Confirm your standing with the destination country's agency before you book the load.
What carrier codes and identifiers do I need?
Two identifiers matter most for cross-border highway freight: a SCAC and, for trips into Canada, a CBSA carrier code. Each ties your eManifest filings back to a recognized carrier record.
A SCAC (Standard Carrier Alpha Code) is a two-to-four-letter identifier assigned by the National Motor Freight Traffic Association (NMFTA). You need a valid SCAC to register for and file ACE eManifests into the US. According to NMFTA, the code must be renewed annually, and as of February 2026 non-Class 8 carriers also pay a small identity-verification fee.
A CBSA carrier code is your identifier for filing ACI eManifests into Canada. You apply for it through the CARM Client Portal. A non-bonded code is free and lets you deliver freight to the first point of arrival. A bonded code requires posting security with CBSA of $5,000 to $25,000 and lets you move in-bond goods inland or in transit through Canada. New carriers almost always start non-bonded.
One important CBSA deadline: after receiving your carrier code you have 30 days to obtain the bar-coded labels used for shipment identification. Miss that window and CBSA can impose a $1,000 penalty when labels are not presented with your shipments.
What insurance do I need for cross-border freight?
The insurance limit that gates your US authority is the FMCSA minimum: $750,000 in liability coverage for general freight carriers such as dry van, flatbed, and reefer. The FMCSA will not grant or keep your operating authority active until proof of the required coverage is on file, and higher limits apply for hazardous materials or heavier vehicles.
For freight into Canada, coverage requirements are driven by the provinces you operate in and by your customers' contracts rather than a single federal figure. In practice, brokers and shippers on both sides of the border often require $1,000,000 or more and want to be named as a certificate holder.
Tell your insurance provider explicitly that you are running cross-border. Some domestic policies exclude trips outside the home country, and a coverage gap discovered at the border is an expensive surprise.
How does the eManifest work, and how early do I file?
An eManifest is the electronic manifest you transmit to the border agency before you arrive, describing the truck, driver, and freight. The US system is ACE (Automated Commercial Environment) run by CBP; the Canadian system is ACI (Advance Commercial Information) run by CBSA.
The timing rule for highway carriers is the part that trips up newcomers. Carriers must transmit ACE data to CBP at least one hour before arriving at the US border, and ACI data to CBSA at least one hour before arriving in Canada. If your carrier, driver, and importer are all FAST-approved, the US window shortens to 30 minutes before arrival. You can also submit an ACE manifest up to 30 days in advance, so there is no reason to leave it to the last mile.
The eManifest does not replace the customs entry; it runs alongside it. The border agency must accept both the carrier's eManifest and the broker's entry before the goods are cleared to cross.
Filing eManifests by hand on a government portal for every load gets old fast. Handling ACE and ACI filing inside your operations software keeps the manifest tied to the same load record your dispatcher and driver are already working from. For a deeper walkthrough of the two systems, see our ACE vs ACI eManifest filing guide.
Do I need a customs broker, or can I file myself?
For your first loads, use a licensed customs broker. A broker files the import entry with CBP or CBSA, classifies the goods, calculates any duties, and coordinates the release number with your eManifest. This is the release side of the crossing, separate from your carrier-side manifest.
Self-filing is legal but demanding. It requires your own accounts with the customs agency, tariff-classification knowledge, and the time to manage entries correctly. Most carriers who eventually self-file start by leaning on a broker until the process is second nature.
The connective tissue between broker and carrier is the release number carried on a sticker:
- A PARS (Pre-Arrival Review System) number is used for shipments entering Canada. The PARS barcode is mandatory on the paperwork.
- A PAPS (Pre-Arrival Processing System) number is used for shipments entering the United States. The PAPS number links your manifest to the broker's entry using a Shipment Control Number, and CBP releases the goods only when the number on your manifest exactly matches the number on the broker's entry.
Get the sticker and number to your broker early. A mismatched or missing number is the single most common reason a well-prepared truck still gets held at the line. Cross-border compliance is one more place where a single source of truth for your operations beats juggling emails and spreadsheets.
What documents does the driver need at the booth?
The driver needs a WHTI-compliant identity document plus the load paperwork. Under the Western Hemisphere Travel Initiative, CBP does not accept a standard provincial or state driver's license on its own at a land crossing.
Acceptable identity documents include:
- A valid passport or passport card
- An enhanced driver's license (available in some provinces and states)
- A FAST card (Free and Secure Trade), the commercial trusted-traveler card that can move a qualifying driver through as much as half an hour faster
- A NEXUS card
On top of identity, the driver should carry a hard copy of their CDL, proof of insurance, and the shipment documents the officer will ask for: the bill of lading, commercial invoice, and packing list. Have the PARS or PAPS sticker on the paperwork and know which broker is clearing the load. The driver's hours-of-service clock also changes at the line, and our US vs Canada HOS comparison breaks down the differences.
How do I plan around border and booth hours?
Plan the crossing itself as a scheduled event, not an afterthought. Not every port of entry is open 24 hours, commercial lanes can close earlier than passenger lanes, and wait times swing hard by time of day and day of week.
Here is a simple master checklist to run before your first cross-border load:
| # | Step | Owner | When |
|---|---|---|---|
| 1 | Confirm US operating authority (MC/USDOT) is active | Office | Before booking |
| 2 | Confirm CBSA carrier code (and labels within 30 days) | Office | Before booking |
| 3 | Verify SCAC is valid and renewed | Office | Before booking |
| 4 | Confirm cross-border insurance limits ($750K US min) | Office | Before booking |
| 5 | Engage a customs broker for the lane | Office | At booking |
| 6 | Collect commercial invoice, BOL, packing list | Dispatch | Load day |
| 7 | Assign PARS (Canada) or PAPS (US) number and sticker | Dispatch/Broker | Load day |
| 8 | File ACE or ACI eManifest (1 hr / 30 min FAST) | Dispatch | Before border |
| 9 | Verify driver's WHTI document, CDL, insurance copy | Driver | Before departure |
| 10 | Confirm port of entry hours and commercial lane status | Dispatch | Before departure |
Give the driver a clear plan for which port to use, its hours, and a fallback if a lane is backed up. Build the eManifest lead time into the trip so the "at least one hour" rule is satisfied comfortably, not by a nervous few minutes.

Frequently Asked Questions
What documents does my driver need to cross the US-Canada border?
Under the Western Hemisphere Travel Initiative, a standard driver's license is not enough. The driver needs a WHTI-compliant document such as a passport, passport card, enhanced driver's license, or FAST card, plus their CDL, proof of insurance, and the shipment paperwork like the bill of lading and commercial invoice.
How early must I file an eManifest before reaching the border?
Highway carriers must transmit ACE manifest data to US CBP at least one hour before arriving at the border, and ACI data to Canada's CBSA at least one hour before arrival. If the carrier, driver, and importer are all FAST-approved, the US window shortens to 30 minutes before arrival. You can file up to 30 days ahead.
What is the difference between a PARS and a PAPS sticker?
PARS (Pre-Arrival Review System) is for shipments entering Canada and PAPS (Pre-Arrival Processing System) is for shipments entering the US. Each carries a barcode that links your eManifest to the customs broker's entry so the border officer can release the load quickly.
Do I need a customs broker for my first cross-border load?
In most cases yes. A licensed customs broker files the import entry with CBP or CBSA and coordinates the PARS or PAPS number with your eManifest. Self-filing is possible but requires accounts and expertise most new cross-border carriers do not yet have.
What insurance do I need to run into the United States?
The FMCSA requires a minimum of $750,000 in liability coverage for general freight carriers, with higher limits for hazardous materials or heavier loads. You must have proof of the required coverage on file before your operating authority is activated.
How do I get a CBSA carrier code?
You apply through the CARM Client Portal. A non-bonded code is free and lets you deliver to the first point of arrival, while a bonded code requires posting security of $5,000 to $25,000 and lets you move in-bond freight inland or in transit. Remember to obtain your bar-coded labels within 30 days.
Bottom Line
A first cross-border load comes down to three tasks done in order: register with the destination country's regulator (FMCSA authority into the US, a CBSA carrier code into Canada), file your eManifest through ACE or ACI at least an hour before arrival, and hand the driver a WHTI document plus complete load paperwork with the right PARS or PAPS sticker. Use a customs broker for your first trips and confirm your insurance meets the $750,000 FMCSA minimum. Plan the crossing as a scheduled event around the port's commercial hours, and your first border run will feel like just another load with a little extra homework.
TorqueAI files your ACE and ACI eManifests inside the same load your dispatcher and driver already use, so nothing falls through the cracks at the border. Explore the product tour →
