Dating yamaha guitars serial number
These serial numbers have 1 letter followed by 4 numbers. For example: J7012 This would be a guitar built in March of 1987 and it was the 12 Unit made that day in the Japan custom shop. For example: 790507 This is simply the 7 guitar built in May (05) in 1979 (79). For example: 860102 This represents the 102(0102) guitar built in 1986 (86). The last 4 (instead of 3) represent the unit number, the rest are the same.The letter represents the month and follows the same system for months as the most common system above. The J is March as per the main system above and the year has to be 1987 since this system was only used between 19. For this short period there is also a 6 digit serial number but doesn’t show the month. This is the same system as used for “Made in Japan Custom Shop 1991 – 1996” except that the unit number started at 501 except for 701. This is the same as for 1997-1999 except there are 10 numbers.If yours doesn’t you’ll need to keep reading to decipher it.
I'm repeating a post I've made in a couple other forums. This past May Yamaha deleted their Yamaha Guitar Archive web page, pushing me to start a forum to share the info that I’ve collected, including all the data from the Yamaha Guitar Archive.It’s widely known that the 8 digit serial numbers start with the year as the first number.But the 6 & 7 digit numbers (located on the neck block) are just sequential numbers used by all the guitars they built, not just the FG’s.I’ve written other articles on: the history of the Yamaha FG 1966-1981 & FG-3XX series; vintage Yamaha truss rod adjustment procedure; vintage Yamaha neck reset procedure; replacement nuts & saddles; Yamaha FG weights; Japanese emperor date codes; Republic of China date codes; and I’m working on many others.My latest interest is decoding the mystery of the 6 & 7 digit serial numbers.

For these ones you will also need to know where your guitar was built – which you should be able to be found next to the serial number of your guitar and will say “made in..” and then the country it was built in (either Japan, Taiwan or Indonesia).
