Warwick Bass Serial Numbers
The following is from our Gearwiki. Please contribute your own knowledge.
Warwick has had a consistent serial number scheme since its foundation in 1982.
A Warwick bass’s serial number can be found on its headstock. Until 1988, it could be found on top of the headstock. Between 1989 and 2007, it was placed between the machine heads on the back of the headstock. Since the end of 2007 it has been placed below the machine heads.
The serial number is a letter followed by a six-digit number and then a two-digit number. The letter represents the month the bass was made.
| Letter | Month |
|---|---|
| A | January |
| B | February |
| C | March |
| D | April |
| E | May |
| F | June |
| G | July |
| H | August |
| J | September |
| K | October |
| L | November |
| M | December |
The last two digits represent the year the bass was made. 1994 becomes 94, 2003 becomes 03, and so on.

The serial number on my thumb bolt-on is M-097154-02. I understand it was made in December, 2002, but the number won’t come up on the Warwick site serial number check “tool”. I’d like to know where it was made, etc. Any ideas?
