Funny tag on fender- what is it?

Murray said
Here are pics of my collection. I think this thread is on the right track. These extra tags are not rare but are not all that common. I think that them not being common and not knowing what they meant is what lead me to collect them. Have always felt that they were inspection tags, but then why did these cars get them and not the others? You can see two examples were a car got a "double tag". The other tags are inconsistent in the material, size and info contained. I'm hoping that someone here worked on the line and can help us.View attachment 1715260276

WOW! That is some collection. I wish I had an index of what was checked and why? I am all for the tag being a "Inspection tag" and it may not correspond to the vin number but just an internal way for inspectors on the line to know before the car rolled out of the factory that it had somebody checking for repairs so it would cut down on dealer warranty claims. My question from there is- did the car have flaws and this was the tag that said those flaws were corrected and by who? or these are the areas where the flaws are and "get it fixed before it ships out?"

Also as a former dealer Tech for GM, when doing the new car inspections of cars that just rolled into the dealership, we would find all sorts of stuff like tools, cig butts, clothing, etc in the cars and would remove them. Tags included- but they were mostly stickers. If I did not remove them the detail dept would. Years ago with Corvettes ( and Buick Grand Nationals and T types)we actually had to remove the PROM chip from the ECU and the correct one was mailed to the dealer upon truck delivery. This way, along the way these cars were not "hot rodded" before it got to the dealer. Sometime they made a few stops between the manufacture to the dealer. A lot of butts in the seat. The temporary PROMS had programming for starting idle and just over idle- like a 1500 rpm rev limiter. I wonder how many cars were trashed before GM came up with that idea. LOL!
