Mopar VIN Numbers

Next is the actually the VIN number.

The first 4 digits are together.

The first digit is a letter and stands for the car line. Example: J = Dodge Challenger

The second digit is also a letter that stands for the price class. Example: S = Special

The third and fourth digits are numbers, which stand for the body style. Example: 23 = 2 Door Hardtop.

In our example it is “JS23”. That decodes to:

J = Dodge Challenger

S = Special (R/T)

23 = 2 Door Hardtop


Then the next 3 digits are grouped together.

The first digit is a letter and stands for the engine. Example: N = 383 1-4BBL 8 CYL.

The second digit is a number that stands for the car year. Example: 0 = 1970.

The third digit is a letter and tells you where the car was built. Example : B = Dodge Main, Hamtramck, MI, USA.

In our example it is “N0B”. That decodes to:

N = 383 330HP OR 335HP 1-4BBL 8 CYL ( Same as above engine code).

0 = 1970 – Remember that this is the number zero.

B = Built at Dodge Main, Hamtramck, MI, USA


Next, there are 6 digits grouped together. This is the production sequence number of car that rolled off the assembly plant.*

In our example the Sequence Number is '100001'.

* Note: This number doesn't mean that your car was the n'th, lets say Barracuda, built. It is for all of the cars built on that assembly line.
