Identification Codes

 

Vehicle Identification Number (VIN)

Vehicle Identification Number (VIN) Locator

The Vehicle Identification Number (VIN) is a 17-digit combination of letters and numbers. The VIN is stamped on a metal tab riveted to the instrument panel top, upper left of the dash. The VIN is also found on the Vehicle Certification (VC) label. If the VIN plate requires replacement, authorized dealers must contact their respective regional office.



Item Description
1 World Manufacturer Identifier (WMI)
2 Restraint-type code
3 Vehicle line and series
4 Engine-type code
5 Computer-generated check digit
6 Model year code
7 Assembly plant code
8 Production sequence number

World Manufacturer Identifier (WMI)

The first 3 VIN positions are the world manufacturer code.

Restraint Type

The fourth VIN position is the vehicle restraint-type code.

Vehicle Line and Series

Positions 5 through 7 indicate vehicle line and series.

Engine Type

The eighth VIN position is the engine displacement and number of cylinders.

Additional engine information can be obtained from the engine tag. Refer to Section 303-01A or Section 303-01B .

Check Digit

The ninth VIN position is a government-assigned, computer-generated check digit.

Model Year

The tenth VIN position is the model year code.

Assembly Plant

The eleventh VIN position is the assembly plant code.

Production Sequence Number

The last 6 VIN positions are a numeric code for the vehicle build sequence. This is also the vehicle serial and warranty number. The serial number can also be found on the engine block, transmission and frame.

 

Vehicle Certification (VC) Label

Vehicle Certification (VC) Label Locator

The Vehicle Certification (VC) label contains the manufacturer name, the month and year of manufacture, the certification statement and the Vehicle Identification Number (VIN). It also includes Gross Vehicle Weight Rating (GVWR).

If a vehicle requires replacement of the VC label and is 4 years old or less, an authorized dealer must submit the VIN to their respective regional office. The regional office will submit a web form to the assembly plant for the replacement label. Once the label has been printed, a representative from the regional office will deliver the label to the dealer and witness installation on the vehicle. If a vehicle is more than 4 years old and requires a replacement label, the dealer must submit a request to the Department of Motor Vehicles.



Item Description
1 Exterior paint code
2 Region code
3 Domestic special order code
4 Interior trim code
5 Tape/paint pinstripe code
6 Radio code
7 Axle code
8 Transmission code
9 Spring code
10 Calibration numbering

Paint Codes

Vehicle paint codes may be listed as a 2-part code. The first set of paint code numbers/letters listed indicate the vehicle primary body color. The second set of numbers/letters listed (if applicable) indicate a 2-tone or accent body color. All colors are base coat/clear coat.

Interior Trim Codes

The interior trim codes are listed as a 2-part code. The first digit listed indicates the seat and fabric style. The second digit listed indicates the interior trim color.

Tape/Paint Pinstripe Codes

Tape and paint pinstripe codes do not apply.

Radio Codes

The following lists the available radio types and codes:

Axle Codes

The following lists the available rear axle ratios.

Additional axle information can be obtained from the axle tag. Refer to Section 205-00 .

Transmission Code

The following lists the available transmission types and codes:

Additional transmission information can be obtained from the transmission tag. Refer to Section 307-01 .

Spring Codes

Spring codes are listed as a 2-part code. The first set of characters identify the front springs. The second set of characters identify the rear springs.

 

Powertrain Calibration Information

NOTE: Powertrain calibration information is limited to a maximum of 5 characters per line on the VC label. Because of this, calibration identification consisting of more than 5 characters will wrap to the second line on the VC label.

Powertrain calibration information is printed in the lower right corner of the VC label. Only the base calibration information is printed. Revision levels will not appear, however, they can be obtained through a scan tool using the most current software revision.



Item Description
1 Model year (year in which calibration strategy was first introduced)
2 Vehicle code
3 Transmission code
4 Unique calibrations (designates different hardware to similar vehicles) Example: tires or drive ratios
5 Fleet code (describes fleet to which the vehicle belongs) Example: 6 — Evaporative Emission (EVAP)
6 Certification region (lead region where multiple regions are included in one calibration) Example: A — US federal
7 Revision level (will advance as revisions occur) Not printed on label

The following offers a more detailed explanation of the coding strategy used.

Model Year

Model year code indicates the year in which the calibration code was introduced.

Vehicle Code

The vehicle code indicates the vehicle line to which the code applies.

Transmission Code

The transmission code identifies the type of transmission used.

Unique Calibration

The Emissions/Corporate Average Fuel Economy/CO2 Compliance Department is responsible for assigning these calibration numbers. Unique identifications are assigned to cover similar vehicles to differentiate between tires, drive configurations, final drive ratios and other calibration-significant factors.

These 2 characters are chosen by the analyst to provide identifiable information unique to each calibration. For example, using the number 2 to denote a 2-valve engine versus using the number 4 to identify a 4-valve engine provides an easily identifiable difference.

Fleet Coding

Identifies the fleet to which the vehicle belongs.

Certification Region

When instances where multiple regions are included in one calibration, the lead region will be listed.
