The 9th digit in a VIN number is the check digit and has nothing to do with the car. The value of this digit can be 0-9 or X and is used to ensure that the VIN# is valid, i.e. CRC.underpressure said:

To get the value of this digit some calculations need to be performed on the rest of the letters/numbers in the VIN#. Using the table below replace all letters with their number value, while leaving the numbers as is.

Code:

```
Letter=Value
A=1 B=2 C=3 D=4 E=5 F=6 G=7 H=8
J=1 K=2 L=3 M=4 N=5 O=6 P=7 R=9
S=2 T=3 U=4 V=5 W=6 X=7 Y=8 Z=9
```

Code:

```
Position=Value
1st=8 2nd=7 3rd=6 4th=5 5th=4 6th=3
7th=2 8th=10 9th=0 10th=9 11th=8 12th=7
13th=6 14th=5 15th=4 16th=3 17th=2
```

Using a VIN# off a car on eBay as an example:

JF1GD70624L509579

With the first table our 17 digit number would be:

16174706243509579

Multiplying the individual digits with table 2 would result in:

8 42 6 35 16 21 0 60 0 36 24 35 0 45 20 21 18

Adding all these products together and you get:

387

Dividing this by 11 will leave you with remainder:

2

Since the VIN# has a 2 in the 9th position, this means that the VIN# has the correct check digit.

EDIT:

Just in case anyone is wondering here are the what the other digits in the VIN# signify:

Code:

```
Position=Purpose=Details
1st=Country of Origin=J (Japan)
2nd=Manufacturer=F (Fuji Heavy Industries)
3rd=Vehicle Type=1 (Passenger Vehicle)
4th=Model=G (Impreza)
5th=Body Type=D (4 Door Sedan)
6th=Displacement/Engine=7 (2.5L Turbo)
7th=Grade=0 (STi)
8th=Restraints=6 (Manual seatbelts, dual airbags, side airbags)
9th=Check Digit=0-9, X
10th=Model Year=4 (2004)
11th=Transmission=L (Full time AWD, 6MT)
12th-17th=Manufacturer Number=(I believe STis are 5XXXXX)
```
