Basically, no.

For us it varies by assembly plant.

Some plants assign the VIN early in the process and build straight through. Those are in the minority.

Most plants have a "bank"/accumulator after the body shop and then again after paint, with multiple "lanes" to input vehicles and draw vehicles from. There is no "first in/first out" relationship. That gives two opportunities to shuffle jobs prior to pulling them for final assembly, based on work load balance, part availabililty, extended repair etc.

Additionally - there are often separate VIN sequences for nameplate (Chevy vs GMC, or Pontiac/Buick/Olds) and sometimes even engine type (V8 starts at 100001 but 6 cylinder starts at 600001). So - based on these constraints the VIN sequence can be dramatically different for two vehicles following each other down the line, as shown here.
