The first character of a VIN is the country of final assembly. 1, 4 and 5 are the United States. 2 is Canada, 3 Mexico, J Japan, K South Korea, W Germany. It is the least ambiguous fact on the entire car — it is not marketing, it is where the thing was screwed together.
Each manufacturer registers World Manufacturer Identifier codes, one per plant and vehicle type. I went through the registry brand by brand and counted where those codes live.
| Brand | Codes registered | Largest share | US share |
|---|---|---|---|
| Kia | 9 | United States 44% | |
| Ford | 60 | United States 47% | |
| Honda | 45 | United States 36% | |
| Toyota | 34 | Japan 41% | |
| Hyundai | 15 | South Korea 40% | |
| Subaru | 6 | Japan 67% | |
| Volkswagen | 11 | Germany 45% | |
| Mercedes-Benz | 37 | Germany 54% | |
| BMW | 18 | Germany 83% |
Kia — a Korean company — has 44% of its codes registered to American plants, against Ford's 47%. Honda's American codes outnumber its Japanese ones. Meanwhile 20% of Ford's codes are Canadian and 17% Mexican.
One honest caveat before anyone quotes this at a barbecue: these are code registrations, not production volumes. A code covers a plant and vehicle type, so it tells you where a brand builds, not how many cars come out of each door. It is a map of manufacturing footprint, not a sales chart.
The badge stopped meaning a country decades ago
Honda has been building cars in Ohio since 1982. Toyota has plants in Kentucky, Indiana, Texas and Mississippi. Kia builds in Georgia, Hyundai in Alabama, BMW in South Carolina — where it runs one of the largest vehicle exporters in the United States, shipping German-badged SUVs to the rest of the world.
Meanwhile American brands moved substantial production to Mexico and Canada. The result is a market where nationality of badge and nationality of assembly have almost nothing to do with each other, and haven't for a generation.
How to check your own car in ten seconds
Look at the first character of the VIN on your dashboard or door jamb:
1, 4, 5 — United States. 2 — Canada. 3 — Mexico. J — Japan. K — South Korea. W — Germany. S — United Kingdom. Z — Italy. Y — Sweden or Finland.
That is assembly location only. A car assembled in Kentucky can be full of imported parts, and one assembled in Japan can carry an American-built engine. If you want the full picture, the Monroney label lists both US/Canadian parts content and the country of origin of the engine and transmission — you can pull the original window sticker by VIN for any car and read it yourself.
Why it matters beyond bragging rights
Assembly plant is genuinely useful information on a used car. Different plants building the same model can have different build-quality reputations and different recall campaigns — recalls are frequently issued for vehicles built at a specific plant between specific dates, which is exactly the information encoded in your VIN.
So when a recall says "vehicles manufactured at the Lincoln, Alabama plant between March and August," your VIN is what decides whether that is your car. A free VIN check resolves it, and our VIN lookup reads the plant, engine and model year out of the number in one go. The rest of what those seventeen digits encode is in how to read a VIN.
Frequently asked questions
How do I tell where my car was built?
The first character of the VIN is the country of final assembly: 1, 4 or 5 for the United States, 2 for Canada, 3 for Mexico, J for Japan, K for South Korea, W for Germany.
Are Japanese and Korean cars built in America?
Many are. In the manufacturer code registry, 44% of Kia's codes and 36% of Honda's are registered to US plants — Honda has more American codes than Japanese ones. Note these are plant registrations rather than production volumes.
Are American-brand cars built in America?
Partly. Ford has 47% of its codes registered to US plants, with 20% Canadian and 17% Mexican. Badge nationality and assembly nationality have been largely disconnected for decades.
Why does the assembly plant matter on a used car?
Recalls are often issued for vehicles built at a specific plant within specific dates. Your VIN encodes both, so it determines whether a given campaign applies to your car.

The Average Engine Lost a Cylinder and Half a Litre
Engines shrank by half a litre in thirty years while the cars they push around gained a thousand pounds. That combination should not work, and the way manufacturers made it work is the reason modern used cars fail differently than old ones.
Ford Sells Three F-Series Trucks. The Gap Between Them Is $19,500
They look almost identical in a parking lot and they cost as differently as a Corolla and a Corvette. I pulled 21,373 F-Series listings to find where the money goes between the 150, the 250 and the 350. One box on the order form explains most of it.
Today's Honda Civic Outweighs a 1981 Mustang
A 2026 Civic weighs 3,223 lb. A 1981 Mustang weighed 2,643 lb. The commuter hatchback is now heavier than the muscle car it used to park next to — and it is not the worst case in the data.
