You might take a look at the History Section of this site Year and Coach Numbers. If a coach was built in 1990 or later, the Coach number is a part of the VIN and used as an identifier to those who know Newells. Newell started that numbering system as part of an accounting system change in 1983 BUT the VIN did not include the Coach number, it included a Sequence Number (ie 004 would be the 4th coach built during that model year) that started over each year. Coaches built between 1983 and 1990 had the Coach Number typically marked on the plans which Newell kept and on various places, sometimes hidden away, on the coach. Several owners have located Coach Numbers on the bottom of the engine doors. Coaches built prior to 1983 did not have a coach number as the current coach numbering system did not exist at that time. There were 384 coaches built prior to the 1983 numbering system. As a result, Newell skipped 384 numbers in 2007 to get the coach numbers to represent those missing unnumbered coaches.

Hope that helps. Let me know if it just confuses things.
