VIN Numbers Starting With 1, 4 or 5 — Built in the United States
If the first character of a VIN is 1, 4 or 5, the vehicle rolled off an assembly line in the United States. That is all the first character tells you — a US-built car can still have been titled in six states, flooded in one of them, and shipped back. Decode the whole VIN to see the rest.

A VIN beginning with 1, 4 or 5 identifies a vehicle manufactured in the United States. ISO 3779 allots those three characters to the US, and SAE International assigns the specific three-character World Manufacturer Identifier within them — 1G1 to Chevrolet, 1FA to Ford, 5YJ to Tesla, 4T1 to Toyota's US plants, and so on. Foreign brands that build in the US get US codes: a BMW assembled in South Carolina starts with 5UX, not W.
Reading a American-built VIN
The first character places the factory. Everything that matters about the individual vehicle comes after it.
- 1Read the first character1, 4 or 5 in position one means US assembly. There is no ranking among them — they were allotted as the US ran out of codes, not by state or by brand.
- 2Read the first threeThe full three-character WMI names the manufacturer and often the plant. 1FT and 1FA are both Ford; one is the truck line.
- 3Decode the restCharacters 4–8 carry the model, body, engine and restraint system. Character 10 is the model year, 11 the plant.
- 4Then check the historyBuild country is a fact about the factory. Title brands, theft records and odometer readings are facts about the car, and only a history report has those.
What the code tells you
Which of the three you have
1 was the original US allotment; 4 and 5 were added as it filled. A 5-prefix VIN is not newer or different in kind — Tesla's Fremont cars and Toyota's Indiana trucks both use 5.
The plant, not just the badge
Ford's 1FA and 1FT split cars from trucks. GM splits Chevrolet, GMC and Cadillac across 1G1, 1GK and 1G6. The WMI is finer-grained than the brand on the grille.
Transplant factories
Honda, Toyota, Nissan, Subaru, BMW, Mercedes-Benz and Volkswagen all hold US WMIs for their American plants. A US-code VIN does not mean a US-owned brand.
What it can't tell you
Nothing about title status, accidents, theft or mileage. Those live in state DMV and insurance records, keyed to the same VIN.
VINs beginning with 1, 4 or 5: manufacturer codes
The first three characters of the VIN are the World Manufacturer Identifier. These are the ones you are most likely to meet on a American-built vehicle — a representative list, not a complete one, since a large manufacturer holds many codes across plants and vehicle classes.
| WMI | Manufacturer | Notes |
|---|---|---|
| 1FA | Ford | Passenger cars |
| 1FT | Ford | Trucks |
| 1FM | Ford | SUVs / multipurpose |
| 1LN | Lincoln | — |
| 1G1 | Chevrolet | Passenger cars |
| 1GC | Chevrolet | Trucks |
| 1GK | GMC | SUVs |
| 1G6 | Cadillac | — |
| 1C4 | Stellantis | Jeep, Dodge, Chrysler |
| 1N4 | Nissan | Smyrna, Tennessee |
| 1HG | Honda | Marysville, Ohio |
| 19U | Acura | — |
| 1VW | Volkswagen | Chattanooga, Tennessee |
| 4T1 | Toyota | Georgetown, Kentucky |
| 5TD | Toyota | Princeton, Indiana |
| 4S4 | Subaru | Lafayette, Indiana |
| 4JG | Mercedes-Benz | Tuscaloosa, Alabama |
| 5UX | BMW | Spartanburg, South Carolina |
| 5YJ | Tesla | Fremont, California |
| 7SA | Tesla | Austin, Texas |

The country code is one character. Enter the full VIN to get the make, model, year and plant — plus title brands, theft records, accidents and open recalls.
Why the United States has three codes and everyone else has one
ISO 3779 divides the first VIN character geographically, then subdivides it. Most countries get a two-character range — Mexico holds 3A through 3W, Sweden holds YS through YW. The United States was allotted the whole of 1, and then, as manufacturers and plants multiplied past what a single leading digit could carry, 4 and 5 as well.
The practical consequence is that you cannot infer anything from which of the three you are looking at. 4 is not newer than 1. 5 does not mean an import brand. They are three doors into the same room, opened in sequence, and a manufacturer applying for a new WMI simply got whatever was free at the time.
This is also why a WMI, not the first character alone, is the useful unit. 1G1 and 1GC are both US-built General Motors vehicles, but one is a Chevrolet passenger car and the other a Chevrolet truck, and the difference matters for everything downstream — recall applicability, part numbers, what the 5th through 8th characters even mean.
US-built does not mean US-titled, and that is the part that costs money
A shopper who checks the first character and stops has answered a manufacturing question, not a buying question. The vehicle in front of you was built in Kentucky; it may since have been titled in Louisiana during a hurricane year, written off by an insurer, rebuilt, and retitled in a state with looser branding rules.
The United States is unusual here because title branding is a state function, not a federal one. A salvage brand issued in one state does not automatically follow the car into the next — that is the whole reason NMVTIS, operated by the US Department of Justice, exists: to give every state a shared place to look. A VIN history report reads those records.
So treat the country code as the first step of a decode, not the answer. Run the seventeen characters through a full check and you get the build data plus the title brands, reported theft records, odometer readings and recall status attached to that specific vehicle.
Frequently Asked Questions
What does a VIN starting with 1 mean?
It means the vehicle was assembled in the United States. 1 was the original US allotment under ISO 3779; 4 and 5 were added later and mean exactly the same thing.
Is a VIN starting with 5 different from one starting with 1?
No. Both indicate US assembly. The specific character was allotted to the manufacturer when it applied for its World Manufacturer Identifier, and carries no information about age, quality or brand origin.
Can a Japanese brand have a VIN starting with 1?
Yes. Honda's Marysville, Ohio plant builds cars with the WMI 1HG, and Nissan's Smyrna, Tennessee plant uses 1N4. The code describes where the vehicle was built, not who owns the brand.
Does a US VIN mean the car was never imported?
No. A US-built vehicle can be exported and re-imported, and plenty are. Only a title history keyed to the VIN shows where it has actually been registered.
