PART 565_VEHICLE IDENTIFICATION NUMBER REQUIREMENTS--Table of Contents

 

Sec. 565.6  Content requirements.



    The VIN shall consist of four sections of characters which shall be 

grouped accordingly:

    (a) The first section shall consist of three characters that occupy 

positions one through three (1-3) in the VIN. This section shall 

uniquely identify the manufacturer, make and type of the motor vehicle 

if its manufacturer produces 500 or more motor vehicles of its type 

annually. If the manufacturer produces less than 500 motor vehicles of 

its type annually, these characters along with the third, fourth and 

fifth characters of the fourth section shall uniquely identify the 

manufacturer, make and type of the motor vehicle. These characters are 

assigned in accordance with Sec. 565.7(a).

    (b) The second section shall consist of five characters, which 

occupy positions four through eight (4-8) in the VIN. This section shall 

uniquely identify the attributes of the vehicle as specified in Table I. 

For passenger cars, and for multipurpose passenger vehicles and trucks 

with a gross vehicle weight rating of 4536 kg. (10,000 lbs.) or less, 

the first and second characters shall be alphabetic and the third and 

fourth characters shall be numeric. The fifth character may be either 

alphabetic or numeric. The characters utilized and their placement 

within the section may be determined by the manufacturer, but the 

specified attributes must be decipherable with information supplied by 

the manufacturer in accordance with Sec. 565.7(c). In submitting the 

required information to NHTSA relating to gross vehicle weight rating, 

the designations in Table II shall be used. The use of these 

designations within the VIN itself is not required. Tables I and II 

follow:



          Table I--Type of Vehicle and Information Decipherable



Passenger car: Line, series, body type, engine type and restraint system 

type.

Multipurpose passenger vehicle: Line, series, body type, engine type, 

gross vehicle weight rating.



[[Page 174]]



Truck: Model or line, series, chassis, cab type, engine type, brake 

system and gross vehicle weight rating.

Bus: Model or line, series, body type, engine type, and brake system

Trailer, including trailer kits and incomplete trailer: Type of trailer, 

body type, length and axle configuration.

Motorcycle: Type of motorcycle, line, engine type, and net brake 

horsepower.

Incomplete Vehicle other than a trailer: Model or line, series, cab 

type, engine type and brake system.



    Note to Table I: Engine net brake horsepower when encoded in the VIN 

shall differ by no more than 10 percent from the actual net brake 

horsepower; shall in the case of motorcycle with an actual net brake 

horsepower of 2 or less, be not more than 2; and shall be greater than 2 

in the case of a motorcycle with an actual brake horsepower greater than 

2.



              Table II--Gross Vehicle Weight Rating Classes



    Class A--Not greater than 1360 kg. (3,000 lbs.)

    Class B--Greater than 1360 kg. to 1814 kg. (3,001-4,000 lbs.)

    Class C--Greater than 1814 kg. to 2268 kg. (4,001-5,000 lbs.)

    Class D--Greater than 2268 kg. to 2722 kg. (5,001-6,000 lbs.)

    Class E--Greater than 2722 kg. to 3175 kg. (6,001-7,000 lbs.)

    Class F--Greater than 3175 kg. to 3629 kg. (7,001-8,000 lbs.)

    Class G--Greater than 3629 kg. to 4082 kg. (8,001-9,000 lbs.)

    Class H--Greater than 4082 kg. to 4536 kg. (9,001-10,000 lbs.)

    Class 3--Greater than 4536 kg. to 6350 kg. (10,001-14,000 lbs.)

    Class 4--Greater than 6350 kg. to 7257 kg. (14,001-16,000 lbs.)

    Class 5--Greater than 7257 kg. to 8845 kg. (16,001-19,500 lbs.)

    Class 6--Greater than 8845 kg. to 11793 kg. (19,501-26,000 lbs.)

    Class 7--Greater than 11793 kg. to 14968 kg.(26,001-33,000 lbs.)

    Class 8--Greater than 14968 kg. (33,001 lbs. and over)



    (c) The third section shall consist of one character, which occupies 

position nine (9) in the VIN. This section shall be the check digit 

whose purpose is to provide a means for verifying the accuracy of any 

VIN transcription. After all other characters in VIN have been 

determined by the manufacturer, the check digit shall be calculated by 

carrying out the mathematical computation specified in paragraphs (c) 

(1) through (4) of this section.

    (1) Assign to each number in the VIN its actual mathematical value 

and assign to each letter the value specified for it in Table III, as 

follows:



                       Table III--Assigned Values



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

P = 7

R = 9

S = 2

T = 3

U = 4

V = 5

W = 6

X = 7

Y = 8

Z = 9



    (2) Multiply the assigned value for each character in the VIN by the 

position weight factor specified in Table IV, as follows:



                Table IV--VIN Position and Weight Factor



 1st...................................................................8

 2d....................................................................7

 3d....................................................................6

 4th...................................................................5

13th...................................................................6

14th...................................................................5

15th...................................................................4

16th...................................................................3

17th...................................................................2



    (3) Add the resulting products and divide the total by 11.

    (4) The numerical remainder is the check digit. If the remainder is 

10 the



[[Page 175]]



letter ``X'' shall be used to designate the check digit. The correct 

numeric remainder, zero through nine (0-9) or the letter ``X,'' shall 

appear in VIN position nine (9).

    (5) A sample check digit calculation is shown in Table V as follows:



                                      Table V--Calculation of a Check Digit

                                                                               .

                                                                               .

Multiply Assigned value times weight factor.   8  49  24   5  32  15  18  80   0  45  56   7   6  40  12  12   2



Add products: 8+49+24+5+32+15+18+80+0+45+56+7+6+40+12+12+2 = 411

Divide by 11: 411/11 = 37 4/11

The remainder is 4; this is the check digit to be inserted in position nine (9) of the VIN



    (d) The fourth section shall consist of eight characters, which 

occupy positions ten through seventeen (10-17) of the VIN. The last five 

(5) characters of this section shall be numeric for passenger cars and 

for multipurpose passenger vehicles and trucks with a gross vehicle 

weight rating of 4536 kg. (10,000 lbs.) or less, and the last four (4) 

characters shall be numeric for all other vehicles.

    (1) The first character of the fourth section shall represent the 

vehicle model year. The year shall be designated as indicated in Table 

VI as follows:

    (2) The second character of the fourth section shall represent the 

plant of manufacture.

    (3) The third through the eighth characters of the fourth section 

shall represent the number sequentially assigned by the manufacturer in 

the production process if the manufacturer produces 500 or more vehicles 

of its type annually. If the manufacturer produces less than 500 motor 

vehicles of its type annually, the third, fourth and fifth characters of 

the fourth section, combined with the three characters of the first 

section, shall uniquely identify the manufacturer, make and type of the 

motor vehicle and the sixth, seventh, and eighth characters of the 

fourth section shall represent the number sequentially assigned by the 

manufacturer in the production process.
