Several changes are being made to the numbering
structure for VINs (Vehicle Identification Numbers) for GM trucks and cars,
beginning with the 2010 model year.
The VIN structure was instituted by all vehicle makers
in 1981 in compliance with government regulatory requirements. The VIN contains
standardized data required by government and insurance agencies.
Trucks and MPVs
For light-duty trucks and multi-purpose vehicles
(MPVs), beginning with 2010, there is a new requirement for the VIN to identify
the restraint system devices and locations. Position 7 will be used for this
purpose (it formerly indicated Body Type). Previously, position 7 Restraint
System was not common between trucks and cars. Now, it is.
In addition, position 4 previously indicated
GVWR/Brake Systems and now indicates GVWR/Brake Systems and Body Style.
Positions 4, 5 and 6 are now alpha-numeric and
position 7 is alpha only. This increases the number of systems that can be
described with a single character. (Fig. 12)

Cars
For cars, the meanings of all of the positions remain
unchanged. Positions 4, 5 and 6 are now alpha-numeric and position 7 is alpha
only. This increases the number of systems that can be described with a single
character.
