2002 ZO6 VIN Number Question

[Paul C.]

Looking at several vin #'s and noticed difference on several 2002 ZO6's.

VIN #1: 1G1YY12S 9 25135000

VIN #2: 1G1YY12S X 25135001

Why does one Vin have a X and one a 9. What is the significance of this digit/letter?

1: USA
G: GM
1: Chevrolet
YY: Corvette
1: Coupe
2: Safety equipment --air bags, etc
S: Motor type--5.7 L seq. fuel injection 2001-2004

X or 9:???

2: Year 2002
5: Built in Kentucky
135000 0r 135001: number in sequence when car was built.

Can someone explain the X or 9--why the difference and what does it stand for.

Thanks Paul

The ninth digit is a security code, or "check digit". It will vary from car to car. Totally in line and normal. Pretty neat to see consecutive VIN #'s though.

The 9th digit in the later (after 1990s someplace) is called a "security" digit. It is calculated by a formula using ALL the other characters in the VIN.

Believe it or not John Amgwert wrote a story about this the The Restorer that was printed sometime in later 1999 or 2000. I believe the information is also on the Internet -- some security, Ehh?

Here is what Google yielded:

Boy was I off on that date. I knew it was just after I left the Editor's job -- but I pulled the wrong dates out of someplace.
