Canadian vs US VIN: What Is the Difference?

Direct answer: Canadian and US VINs share the same 17-character ISO 3779/3780 format and 9th-digit check digit math, but key differences exist in manufacturing origin, safety standards, and cross-border records. Vehicles manufactured in Canada start with World Manufacturer Identifier (WMI) digit 2, while US-manufactured vehicles start with 1, 4, or 5. Additionally, Canadian market vehicles feature Canadian Motor Vehicle Safety Standards (CMVSS) compliance labels, factory Daytime Running Lights (DRL), and primary metric (km/h) instrument displays.

17-Character VIN Structure Breakdown

Primary sources: NHTSA vPIC API; Transport Canada: Defects and recalls.

Both Transport Canada (CMVSS 115) and the US NHTSA (49 CFR Part 565) enforce the standard 17-character structure:

Positions	Section Name	Canadian vs US Specification
1–3	World Manufacturer Identifier (WMI)	Position 1 indicates manufacturing country: 2 = Canada; 1, 4, 5 = USA; 3 = Mexico; J = Japan; W = Germany.
4–8	Vehicle Descriptor Section (VDS)	Encodes body style, engine type, model series, and safety system features.
9	Check Digit	Calculated mathematical check digit (weighted mod 11 algorithm) required on all North American VINs.
10	Model Year Code	Standardized year character (e.g., L = 2020, P = 2023, R = 2024, S = 2025, T = 2026).
11	Assembly Plant Code	Manufacturer-specific plant identification code.
12–17	Vehicle Identifier Section (VIS)	Unique sequential production serial number for the vehicle.

Key Differences: Canadian Market vs US Market Vehicles

Primary sources: NHTSA vPIC API; Transport Canada: Defects and recalls.

Feature	Canadian Market Vehicle	US Market Vehicle
First VIN Digit (WMI)	Starts with 2 if manufactured in Canada (or J/W/K if imported from overseas for Canadian market).	Starts with 1, 4, or 5 if manufactured in the US.
Safety Compliance Label	CMVSS statement of compliance label with maple leaf / Transport Canada national safety mark.	FMVSS statement of compliance label (U.S. Department of Transportation).
Speedometer & Odometer	Primary display in km/h and kilometers.	Primary display in mph and miles.
Daytime Running Lights (DRL)	Mandatory factory equipment since 1989/1990 model year.	Optional depending on state regulations and manufacturer specs.
Cross-Border History Records	Provincial registries (ServiceOntario, ICBC, SAAQ) and Canadian vehicle history databases.	State DMV records, National Motor Vehicle Title Information System (NMVTIS), and US title history.

Cross-Border Diligence: Importing & Buying US Vehicles in Canada

Primary sources: Registrar of Imported Vehicles (RIV Canada); Transport Canada: Defects and recalls.

When buying a used US-market vehicle in Canada or importing one across the border:

1. Registrar of Imported Vehicles (RIV) Compliance: Verify the vehicle is admissible into Canada on Transport Canada's RIV List of Admissible Vehicles before purchasing.
2. Cross-Border History Check: Always pull a history report that queries both US state DMV / NMVTIS records and Canadian provincial records. US salvage, flood, or lemon titles might not immediately populate on a Canadian provincial search if the vehicle was recently imported.
3. Recall Clearance: Transport Canada and RIV require proof that all open manufacturer safety recalls have been completed before final provincial registration.
4. Instrument & Lighting Modifications: Imported US vehicles must be modified to meet Canadian standards (activation of DRLs, child tether anchorages, and metric speedo verification during RIV Form 2 inspection).
