Digit Definition

1st Country of Origin: 1 = USA 2nd Manufacturer: G = General Motors 3rd Make: 1 = Chevrolet 4th/5th Carline/Series: YY = Corvette 6th Body Style: 1 = hardtop, 2 = two door coupe, 3 = two door convertible 7th Restraint Code: 2 = active, manual w/driver and passenger inflatable restraints. 8th Engine Type: G = LS1, S = LS6 9th Check Digit 10th Model Year: 1 = 2001 11th Plant: 5 = Bowling Green KY Last 6 digits Production number for model year (100001 – 135627).

GM VIN CHECK DIGIT VERIFICATION

To determine check digit (9th digit) of your GM car, assign numeric values to any letters found in the VIN Code, according to the following table: A = B = C = D = E = F = G = H = 1 2 3 4 5 6 7 8 K = L = M = N = O = P = R = J = 1 2 3 4 5 6 7 9 S = T = U = V = W = X = Y = Z = 2 3 4 5 6 7 8 9 Any numbers in the VIN retain their original value (not replaced). This yields a 17 digit number.

Then you multiply each of the 17 digits by a set "multiplier". The multiplier associated with each digit is found in this table:

1st 2nd 3rd 4th 5th 6th 7th 8th Check 8 7 6 5 4 3 2 10 0 11t 12t 13t 14t 15t 16t 17t 10th h h h h h h h 9 8 7 6 5 4 3 2

After multiplying each VIN digit by the associated weight - sum each of the 17 products. Divide this total by 11. The remainder is the check digit. (modulus 11) If the remainder is 10, then the check digit is 'X'.

Here's an example: VIN = 1 G 1 B L 5 2 P 7 T R 1 1 5 5 2 0 (note '7' is the check digit) VIN Code 1 G 1 B L 5 2 P 7 T R 1 1 5 5 2 0 Assigned 1 7 1 2 3 5 2 7 7 3 9 1 1 5 5 2 0 Value Multiplier 8 7 6 5 4 3 2 10 0 9 8 7 6 5 4 3 2 Add the (1 x 8) + (7 x 7) + (1 x 6) + ...... + (5 x 4) + (2 x Products 3) + (0 x 2) = 337 Divide 337 by 11 which gives you 30, and a remainder of 7 which is the same as the 9th digit of the VIN.

GM VIN CHECK DIGIT VERIFICATION

To determine check digit (9th digit) of your car you need to take the VIN and assign any letters in the VIN with a set value (number) as follows:

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

Any numbers in the VIN remain the same (not replaced) and thus you have a 17 digit number.

Then you must multiply each of the 17 digits by a set "weight" (multiplier). The weight applied to each digit is as follows:

1st = 8, 2nd = 7, 3rd = 6, 4th = 5, 5th = 4, 6th = 3, 7th = 2, 8th = 10,

9th = 0 (check digit), 10th = 9, 11th = 8, 12th = 7, 13th = 6, 14th = 5,

15th = 4, 16th = 3, 17th = 2 After multiplying each VIN digit by the associated weight - add up the results of all 17 products. Then divide by 11 and the remainder is your check digit.

If the remained is 10, then the check digit is 'X'.

Here's an example: VIN = 1G1BL52P7TR115520 (note '7' is the check digit)

VIN 1 G 1 B L 5 2 P 7 T R 1 1 5 5 2 0

Assigned Values 1 7 1 2 3 5 2 7 7 3 9 1 1 5 5 2 0

Multiplier 8 7 6 5 4 3 2 10 0 9 8 7 6 5 4 3 2

Add the products: (1 X 8) + (7 X 7) + (1 X 6) ... (0 X 2) = 337

Divide 337 by 11 which gives you 30, and a remainder of 7 which is the same as the 9th digit of the VIN.
