The first three characters of a VIN are the World Manufacturer Identifier (WMI). They're assigned through a system run by SAE International on behalf of NHTSA, using ISO 3779 region and country ranges. For buyers, the WMI is a quick sanity check on where and by whom a car was made. This post shows how to read it and what it does not mean.
Character 1: region
| First character | Region |
|---|---|
| A-H | Africa |
| J-R | Asia (e.g. J = Japan, K = South Korea, L = China) |
| S-Z | Europe (e.g. S = UK, V = France/Spain, W = Germany, Y = Sweden/Finland, Z = Italy) |
| 1-5 | North America (1, 4, 5 = United States, 2 = Canada, 3 = Mexico) |
| 6-7 | Oceania (6 = Australia) |
| 8-9 | South America (9 = Brazil) |
Country assignments are actually two-character ranges, so a precise lookup uses characters 1-2. The table is the practical summary.
Characters 2-3: manufacturer and type
Together, the three characters identify a specific manufacturer and often the vehicle type (passenger car, truck, MPV). A few well-known examples:
-
1HG- Honda, built in the U.S. -
JHM- Honda, built in Japan -
WBA- BMW, Germany -
5YJ- Tesla, U.S. -
KMH- Hyundai, South Korea
Some brands use many WMIs, one per plant country or vehicle type.
Low-volume manufacturers
Makers producing fewer than 1,000 vehicles per year use a 9 as the third character, and positions 12-14 of the VIN complete their identifier.
What the WMI does NOT tell you
- Brand nationality. A "1" means built in the U.S., not an American brand. Plenty of Japanese and German brands build cars in North America.
- Where the car was sold. A Canadian-market car can carry a U.S. WMI and vice versa.
- History. The WMI is a factory fact, nothing about ownership, accidents or title brands.
Why buyers should care
- Spot mismatches. If an ad says "Japanese-built" but the VIN starts with 1, 4 or 5, the seller is wrong or the VIN doesn't belong to the car.
- Import checks. Grey-market imports often have VINs that don't follow the 17-character format or carry unusual WMIs. Check eligibility and title paperwork carefully.
- Parts and recalls. Plant country can matter for parts variants and some recall populations, which are sometimes plant-specific.
For developers
- Don't hard-code WMI tables; they change. NHTSA's vPIC database exposes manufacturer lookups (
DecodeWMI,GetWMIsForManufacturer). - Use the full-VIN decode for make and plant country rather than inferring from the first character.
- Display "Plant country" separately from "Make" in your UI to avoid the nationality confusion.
Summary
The WMI tells you who made a vehicle and roughly where. It's a two-second check that catches sloppy or fraudulent listings, as long as you don't read it as brand nationality or history.
