How Do You Decipher a VIN?
VIN information is organized in groups. The first group, made up of three digits, is what's called the world manufacturer identifier (WMI).
- In this group, the first digit or letter identifies the country of origin. For example, cars made in the U.S. start with 1, 4 or 5. Canada is 2, and Mexico is 3. Japan is J, South Korea is K, England is S, Germany is W, and Sweden or Finland is Y.
- The second digit in this group tells you about the manufacturer. In some cases, it's the letter that begins the manufacturer's name. For example, A is for Audi, B is for BMW, G is for General Motors, L is for Lincoln and N is for Nissan. But that "A" can also stand for Jaguar or Mitsubishi, and an "R" can also mean Audi. It may sound confusing, but the next digit ties it all together.
- The third digit, when combined with the first two digits, indicates the vehicle's type or manufacturing division. This Wikipedia page has a list of WMI codes.
The next six digits (positions 4-9) make up the vehicle descriptor section.
- Digits 4 through 8 describe the car with such information as the model, body type, restraint system, transmission type and engine code.
- Digit 9, the "check" digit, is used to detect invalid VINs, based on a mathematical formula that was developed by the Department of Transportation.
The following group of eight digits (10-17) is the vehicle identifier section.
- In the 10th position, you won't find a number. Instead, you'll see a letter, indicating the model year. The letters from B to Y correspond to the model years 1981 to 2000. There is no I, O, Q, U or Z. From 2001 to 2009, the numbers 1 through 9 were used in place of letters. The alphabet started over from A in 2010 and will continue until 2030.
Is it confusing? Yes. Here's a list of the model years since 2000: Y=2000, 1='01, 2='02, 3='03, 4='04, 5='05, 6='06, 7='07, 8='08, 9='09, A='10, B='11, C='12, D='13, E='14, F='15, G='16, H='17, J='18, K='19, L='20.
- The letter or number in position 11 indicates the manufacturing plant where the vehicle was assembled. Each automaker has its own set of plant codes.
- The last six digits (positions 12 through 17) are the production sequence numbers. This is the number each car receives on the assembly line.
