Boss Serial Number Decoder. Value and date finder for Boss pedals

Trying to work out if your Japanese DS-1 is from 1978 or 1985? Looking to sell your 80's CE-2 and want to list it as accurately as possible? Here's our cheat-sheet for understanding your Boss serial number and how some of the systems work! Types of serial: There are THREE main serial number sequences used for Japanese Boss pedals.

Located above the switch inside the battery compartment, these codes are stamped directly to the enclosure using black ink or white ink on darker pedals like the SG-1. The first batch of Boss pedals were made in October, 1977 and featured the code 6300 for the whole month of production.

The second month November, 1977 were labelled 6400, the third December, 1977 were 6500 and so on. This system continued all the way through to around April, 1981 at 10500 or sometimes just 0500. As these were just batch codes and not specific serial numbers, they are not unique to the pedal and you will often see two of the same or different pedals with dating your boss dating your boss pedal numbers.

The number moved to a sticker inside the battery compartment under where the battery would sit dating your boss pedal feature a 6 digit code.

The first two digits are the primary modifier in these codes, starting with 02XXXX at January 1981. Like the previous format, the sequence went month by month with 03XXXX being February 1981, 04XXXX being March 1981 and so on. This system can theoretically be used up to 99XXXX February 1989. This system was more complex than the previous batch code system and the last four digits of the serial varied slightly likely due to there being multiple batches being produced in a single month.

The numbers still weren't unique though and you will once again find identical numbers dating your boss pedal two different pedals. XA0XXXX is the first code used which indicates March, 1989 following on from the previous system and is followed by XA1XXXX April, 1989XA2XXXX May, 1989 and so on.

After XA9XXXX December, 1989 the letter changes to B and the cycle continues. This serial number can theoretically be used all the way through to the 90's, although Japanese production ended in the mid 90's so it's unlikely you'll see anything with second letter past E for a Japanese pedal.

I believe this is the first true "Serial Number" format with unique numbers for each pedal rather than monthly batches. This serial number format continued for a while longer with Taiwanese pedals until they ran out of letters at Z in 2010.
