Vehicle identification number

From Wikipedia, the free encyclopedia

"VIN" redirects here. For other uses, see Vin (disambiguation).

Vehicle Identification Numbers (VINs) are used to uniquely identify motor vehicles. Prior to 1980 there was not an accepted standard for these numbers, so different manufacturers used different formats. Modern day VINs consist of 17 characters that do not include the letters I, O or Q. In the United States a confidential vehicle identification number is used with certain major assemblies of a vehicle and is known only to designated persons within the Federal Bureau of Investigation and the National Automobile Theft Bureau.

[edit] Parts of the VIN

Modern Vehicle Identification Number systems are based on two related standards originally issued by the ISO in 1979 and 1980, ISO 3779 and ISO 3780, respectively. Compatible, but somewhat different, implementations of these ISO standards have been adopted by the European Union and the United States of America.

The VIN is composed of the following sections:

Standard 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17
ISO 3779 WMI VDS VIS
North American

> 500 vehicles / year

Manufacturer Identifier Vehicle Attributes Check Digit Model Year Plant Code Sequential Number
North American

< 500 vehicles / year

Manufacturer Identifier Vehicle Attributes Check Digit Model Year Plant Code Manufacturer Identifier Sequential Number

[edit] World Manufacturer Identifier

The first three characters uniquely identify the manufacturer of the vehicle using the World Manufacturer Identifier or WMI code. A manufacturer that builds fewer than 500 vehicles per year uses a 9 as the third digit and the 12th, 13th and 14th position of the VIN for a second part of the identification. Some manufacturers use the third character as a code for a vehicle category (e.g., bus or truck), a division within a manufacturer, or both. For example, within 1G (assigned to General Motors in the United States), 1G1 represents Chevrolet passenger cars; 1G2, Pontiac passenger cars; and 1GC, Chevrolet trucks.

[edit] WMI Regions

The first character of the WMI is the region in which the manufacturer is located. In practice, each is assigned to a country of manufacture. Common auto-manufacturing countries are noted.

[edit] Vehicle Descriptor Section

The 4th through 9th positions in the VIN are the Vehicle Descriptor Section or VDS. This is used, according to local regulations, to identify the vehicle type and may include information on the platform used, the model, and the body style. Each manufacturer has a unique system for using this field.

[edit] North American Check Digits

One element that is fairly consistent is the use of position 9 as a check digit, compulsory for vehicles in North America and used fairly consistently even outside this rule.

[edit] Vehicle Identifier Section

The 10th through 17th positions are used as the Vehicle Identifier Section or VIS. This is used by the manufacturer to identify the individual vehicle in question. This may include information on options installed or engine and transmission choices, but often is a simple sequential number. In fact, in North America, the last five digits must be numeric.

[edit] North American Model Year

One consistent element of the VIS is character number 10, which is required (in North America) to encode the model year of the vehicle.

[edit] North American Plant Code

Another consistently-used element (which is compulsory in North America) is the use of the 11th character to encode the factory of manufacture of the vehicle. Although each manufacturer has their own set of plant codes, their location in the VIN is standardized.

[edit] Model year encoding

Besides the three letters that are not allowed in the VIN itself (I, O and Q), the letters U and Z and the digit 0 are not used for the year code. Note that the year code can be the calendar year in which a vehicle is built, or a model or type year allocated by the manufacturer. The year 1980 is encoded as "A", and subsequent years increment through the allowed letters, so that "Y" represents the year 2000. 2001 through 2009 are encoded as the digits 1 through 9, and subsequent years are encoded as "A", "B", "C", etc.

Code Year Code Year Code Year Code Year
A 1980 L 1990 Y 2000 A 2010
B 1981 M 1991 1 2001 B 2011
C 1982 N 1992 2 2002 C 2012
D 1983 P 1993 3 2003 D 2013
E 1984 R 1994 4 2004
F 1985 S 1995 5 2005
G 1986 T 1996 6 2006
H 1987 V 1997 7 2007
J 1988 W 1998 8 2008
K 1989 X 1999 9 2009

[edit] Memorizing the year codes

For some occupations, it can be beneficial to memorize the year VIN code. One easy way to more easily recall each year code is to relate a rhyme or similarity between the actual year and the VIN code. Here are a few easy ways to remember them:

  • 1993 - P
    • Ninety-three rhymes with P.
  • 1995 - S
    • The '5' in '95' looks similar to an 'S'.
  • 1997 - V
    • V looks similar to a rotated '7'.
  • 2000 - Y
    • Y may remind you of 'Year 2000'.

[edit] Check digit calculation

Firstly, find the numerical value associated with each letter in the VIN. (I, O and Q are not allowed.) Digits use their own values.

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

Secondly, look up the weight factor for each position in the VIN except the 9th (the position of the check digit).

1st: ×8 5th: ×4 10th: ×9 14th: ×5
2nd: ×7 6th: ×3 11th: ×8 15th: ×4
3rd: ×6 7th: ×2 12th: ×7 16th: ×3
4th: ×5 8th: ×10 13th: ×6 17th: ×2

Thirdly, multiply the numbers and the numerical values of the letters by their assigned weight factor, and sum the resulting products. Divide the sum of the products by 11. The remainder is the check digit. If the remainder is 10, the check digit is the letter X.

[edit] Example

Consider the hypothetical VIN 1M8GDM9A_KP042788, where the underscore will be the check digit.

     VIN:  1  M  8  G  D  M  9  A  _  K  P  0  4  2  7  8  8
   Value:  1  4  8  7  4  4  9  1  0  2  7  0  4  2  7  8  8
  Weight:  8  7  6  5  4  3  2 10  0  9  8  7  6  5  4  3  2
Products:  8 28 48 35 16 12 18 10  0 18 56  0 24 10 28 24 16

The sum of all 16 products is 351. Dividing by 11 gives a remainder of 10, so the check digit is "X" and the complete VIN is 1M8GDM9AXKP042788.
