The fastest way is to enter your VIN; we look up the plant in NHTSA's database. Here's how to read the clues yourself.
1. The first character of the VIN
The first character is a region code that usually identifies a country. For some characters (3, K, S, Y and Z) the first two characters together decide the country.
| First character | Usually means |
|---|---|
| 1, 4, 5 | United States |
| 2 | Canada |
| 3 | Mexico (some 3 codes belong to Central American and Caribbean countries) |
| J | Japan |
| K | South Korea for KL–KR (other K codes cover countries such as Israel) |
| L | China |
| S | United Kingdom for SA–SM (other S codes cover countries such as Germany and Poland) |
| W | Germany |
| Y | Sweden or Finland for most car brands (Y also covers Belgium, Norway and Ukraine) |
| Z | Italy for most car brands (Z also covers Slovenia and Lithuania) |
Some newer US manufacturers use codes starting with 7. For example, NHTSA decodes 7SA as Tesla, 7FC as Rivian and 7JR as Volvo's South Carolina plant.
It's a good first clue but not proof: the code identifies the manufacturer, and some vehicles are assembled somewhere other than the country it suggests.
2. The eleventh character: the plant code
The 11th character identifies the specific assembly plant. Each manufacturer assigns its own codes, so a "U" means a different factory for Honda than for Ford. A decoder such as ours (which uses NHTSA's database) translates it into a city, state and country.
3. The window sticker
New cars, SUVs, vans and light trucks (up to 8,500 lb GVWR) sold in the US carry a window sticker with a parts-content section required by the American Automobile Labeling Act. It lists the final assembly point (city, state and country), the share of US and Canadian parts, and the countries where the engine and transmission were made. If you kept your sticker, it's the most direct record for your exact vehicle. Motorcycles and heavier pickups and vans aren't covered by this label, so for them the VIN is the main record.
4. The door-jamb label
The certification label, usually on the driver's door edge or door pillar (on a motorcycle, typically near the steering head), shows the manufacturer, the month and year of manufacture and the gross vehicle weight rating (GVWR). It doesn't always name the plant, but the GVWR is useful for the car loan interest deduction, which requires a GVWR below 14,000 lb.
Why it matters now
For tax years 2025 through 2028, interest on a loan for a new vehicle is deductible only if its final assembly happened in the United States. Many models are built in more than one country, so the model name alone isn't enough; your VIN is. See the full rules.
