Effective November 2, 2009, Taylor officially revised its serial numbering system.The change occurred as part of a transition to a new software system that was implemented to improve the company’s inventory management.The new serial numbering convention takes into account Taylor’s two manufacturing locations: its main complex in El Cajon, California and a second factory complex located in nearby Tecate, Mexico.
It takes days to make each Taylor guitar, and the serial number indicates only the day a particular guitar was started in assembly.
The year of manufacture for SE guitars can be determined by the letter prefix prior to the sequence of numbers that follow.
The serial number of an speaker cabinet is located on the back of the cabinet in the upper right corner.
After the year prefix, these models use a code of "EB", indicating Electric Bass.
The serial number on SE model guitars can be found on the back of the headstock.
