I’ve been looking at dealer order numbers for about 40 years and have never seen any intelligence encoded in them. They do increment up numerically, in batches (based on the ordering entity), but the prefix does not seem to have any rhyme or reason.

In the full size truck example below the builds were received in dealer order number sequence, but were re-sequenced by the receiving plant based on internal constraints (assembler work load leveling or material availability) into "Primary Vehicle Identifier" order before the builds were released for production. After the build is underway (through body shop and paint) they are shuffled yet again prior to final line into General Assembly sequence order.

The GA sequence would be the order they popped off the end of the assembly line.
