What a VIN is and how to read it
A Vehicle Identification Number (VIN) is the 17-character code that uniquely identifies a vehicle. It isn't random — each block tells you who built the car, what it is, and exactly which unit you're looking at. Here's how to read every character, and what's different about European VINs.
The 17 characters, block by block
Every VIN follows the international ISO 3779 standard: 17 characters in three blocks. The letters I, O and Q are never used, so they're never mistaken for 1 and 0.
Identifies the manufacturer and the country of build. The first character alone points to a world region — "W", for example, marks Germany.
Describes the model: body style, engine, restraint system and other attributes. Character 9 is a check digit — mandatory only in North America (see below).
Identifies the individual vehicle. In North America the 10th character is the model year, followed by the assembly plant and a unique serial number.
What's different about European VINs
Most VIN explainers copy the North-American rulebook. Several of those rules don't hold for European cars — this is where they differ, and where we get it right.
Position 10 isn't always the model year
"The 10th character is the model year" is a North-American (FMVSS) rule. It is not part of the worldwide ISO 3779 standard, and many European manufacturers don't encode the year there at all.
Some makers use position 11 for the year
Ford's European plants, for example, encode the model year at position 11 and use position 10 for the assembly plant — the reverse of the US layout.
Model year ≠ production or registration year
Where a year is encoded, it's the model year the maker assigned — not necessarily when the car was built or first registered. A late-2023 build can be a 2024 model first registered in 2024.
A missing check digit is normal
Character 9 is a calculated check digit, but it's only mandatory for North-American VINs. Plenty of genuine European VINs carry no valid check digit, so a failed check doesn't mean the VIN is fake.
First character → world region
The very first character of any VIN narrows down where the vehicle was built. This part of the standard is public:

VIN questions, answered
How can I tell if a VIN is real?
Structure is the first check: a real VIN is exactly 17 characters, never contains I, O or Q, and starts with a valid world-region character. The position-9 check digit is only reliable for North-American VINs — many genuine European VINs don't carry a valid one, so a failed check digit alone doesn't prove a VIN is fake.
Where do I find the VIN on my car?
The most common spots are the lower corner of the windshield on the driver's side, the sticker inside the driver's door jamb, and your registration, title and insurance documents. It's also stamped into the bodywork in the engine bay.
What does position 10 mean on a European car?
On North-American VINs the 10th character is the model year. That rule isn't part of the worldwide ISO 3779 standard, so on many European cars position 10 is not the year — some makers (such as Ford of Europe) put the model year at position 11 instead, and others don't encode it in a fixed position at all.
Why does my VIN have no check digit?
The 9th-character check digit is mandatory only for vehicles built to North-American rules. Outside North America it's optional, so many legitimate European VINs leave it blank or carry a value that doesn't validate. That's normal and doesn't mean anything is wrong.
