The first Duesenberg instruments already feature a six-digit serial number, which is based on the YYxxxxsystem. The first two digits represent the year of manufacture, the following four digits show the consecutive production numbers for all models and all years until 2009.
950023 = the 23rd Duesenberg instrument, built in 1995.
990765 = the 765th Duesenberg instrument, built in 1999.
In 2009, this system was revised, redefined and has remained current to this day. The serial numbers still have six digits, the first two digits still indicate the year of manufacture, but the following number now represents the production number across all models and per year.
101145 = the 1145th Duesenberg instrument in 2010.
201483 = the 1483rd Duesenberg instrument in 2020.
The very first Starplayer Special and V-Caster (2002, with two-bolt neck) have five-digit serial numbers, of which the first two indicate the year of manufacture.
From 2005 on, V-Caster, D-Caster and D-Bass got partially no serial numbers, or, just like the 49er, numbers according to another system, which was valid until 2008/09. Here, the serial number consists of a model code with three letters, a hyphen, another letter that indicates the year of manufacture (alphabetical order, e.g. an F stands for 2006, because F is the sixth letter of the alphabet) followed by a three-digit number, the consecutive production number per model.
DCA-E002 = the second D-Caster in 2005
D49-F012 = the twelfth 49er in 2006
DDB-H012 = the twelfth D-Bass in 2008
In 2003/04, a batch of Starplayer TV Special in Black and Silver Sparkle was built without serial numbers, mainly for the American market.
