That's the PVI number ("Primary Vehicle Identifier") which, for Fremont, morphs into the General Assembly sequence number. Flint and Oshawa trucks can also have a stamp in this area.

The PVI is assigned as soon as the dealer order number is delegated to a particular vehicle assembly plant. The PVI is the primary identifier, typically through the body shop, until the VIN and GA sequence number are assigned. At that point the GA sequence number is the "gold source". Nobody cares about the VIN in the vehicle assembly plant (other than getting it on the right vehicle).

For most plants the build order can be shuffled after body shop (before paint) and again after paint (before trim), in order to level work load due to option content or protect against part shortages. In those cases the GA sequence number will be something different than the PVI.

Fremont built straight through (no shuffling) so that's why the PVI will match the GA sequence number.

I'm not sure what that could be, either. Perhaps another indication of trim level. Have to keep our eyes peeled on that one.
