Default VIN Question

Can a coupe and convertible have the same last six digits in the vin? (I know they can't because that is the sequence number off the line). There is a convertible in the Corvette registry with matching vin as my coupe except for the fourth digit. Mine is 3 for a coupe and the other is 6 for convertible.

For the same year the answer is no with respect to the VIN. They can have the same body number on the trim tag, though.

They probably just made a mistake / typo in the listing on the registry. If you get your car up on a lift, you can check your frame stamp. It is on the top frame arch by the rear drivers tire.

I'll check mine next time it is on the lift, but I know the history of the car and it is definitely correct, all numbers matched, plus shipping data and POP. I was going to put mine on the Corvette Registry, but I guess I'll skip it, no use in causing waves. These two cars are a thousand miles apart, so there should never be an issue.

The registry is only as good as the person imputing the data. Someone can make up anything they want and put it on there and no one would know. That is the problem with them.

The frame numbers are on top of the frame not on the side. One below the drivers door one above the rear tire.

Hope that one doesn't get stolen - hopefully the 1 digit difference would be enough to prevent a problem for YOU. But as we saw with the '59 in Kansas, that was impounded because the tag had at one time been removed then replaced, common sense doesn't always exist in bureaucracies.

The longer THAT car exists without somebody making a stink, the more legitimacy it has. What if an owner of that one tries to say yours is a fraud?

Lots of time on the registry, they have contact information. I would reach out and just carefully question if the VIN listed is a typo (not exposing that you have the same VIN). If just a typo, they could easily correct it and you can sleep at night...

And the frame stamp doesn't lie. I would get a picture of yours for your records...

Well I would like to agree with you but about two weeks ago I was stripping the frame on my 65 Pontiac before it goes to the blaster. I have the PHS documents and the VIN plate is untouched and matches the PHS docs. This is not gonig to be a correct resto sort of a restomod. I thought about even replacing the frame with a Morrison but too expensive. Anyway I decided to check the frame numbers on the drivers side rear frame rail. The number is correct except the last digit is a 5 instead of a six. So did the guy on the line lose count?

Interesting. Is it difficult to correct a mistake in the registry? I made one inputting my Z-28. I contacted the moderator and don't remember it ever getting updated. I think the Z-28 one is dead anyway. Or my old links are perhaps broken.

Yes, 65 Pro Vette is correct...top of the frame rail not the side (been years since I looked for mine)

"GM stamped the last six digits of the serial number along with “S” for St. Louis. In spite of the typical corrosion found in this area, the VIN is legible on this Midyear chassis. The stamping is close to the outside edge of the frame rail directly above the driver-side rear tire. This number should coincide with the VIN. Bring a wire brush and flashlight to help find this stamping. Of course, it is a good idea to ask the Corvette owner before you go scraping and brushing on the car."

There may be an issue if some poor sole buys the car in the future. If you want your car on the Registry, I would put it there for sure. Best to have all your documentation in order. Someday this may come back to you. If your car is as original and documented as you say, make sure the world knows it. Just ask the guys who have to represent owners like you in court.

Regards, Joe

There is a button on the left of the web page that allows you to ask for ownership of the car. They will send an email to the last person attached to the car, and if they don't object they transfer it to you. If they do, you have to send them documentation that it's yours. Once the car is attached to your account you are able to update all the details.

This is actually identicle to the question being asked here.
The 6 and the 3 are the only difference in the VIN

Not weird at all. 30837 would be a coupe. 30867 would be a convertible…can’t have two cars with the same last six of the serial number. One of these two cars has a reproduction VIN tag...and I bet it's the coupe currently for sale on BAT.

That VIN tag on the bring a trailer car doesn't appear bad. But anyone can make a mistake!

It is not usual for BJ to miss transcribe a VIN in their sales listings, if the convertible was. Maybe the convertible is fake? No picture of that VIN tag.

Good luck getting any sort of response from the Registry. I've tried a few times over the same issue and heard nothing back.

In the C2 Registry, there's a '63 listed under my account that doesn't belong to me. The owner's name is John Gamble and I've tried to get this listing corrected — crickets. I even emailed the C3 Registry contact hoping it would be forwarded to the C2 admin, but again, crickets.
