Ever wondered what your Yamaha guitar serial numbers tell you about your guitar? Or maybe you’re just curious about the year that your guitar was built?

Here’s the system that Yamaha uses for their acoustic guitar serial numbers and what those numbers can tell you about your guitar.

Table of Contents

Where to Find the Serial Number

If you don’t already have your serial number, you’ll need to locate it. And in some cases you’ll need to find out where your guitar was made as well.

This information will usually be found next to the serial number and will say “made in..” and then the country that the guitar was built in (either Japan, Taiwan or Indonesia).

This information is usually found inside the sound hole of your guitar.

How to Decode your Serial Number

Yamaha’s serial number system (like on your Yamaha LLC or Yamaha FG800) is one of the more complicated ones I have come across, so it’s a little bit involved.

But the complexity of decoding the number isn’t the most frustrating part of this particular serial number system. It’s the fact that the serial numbers actually repeat every decade, so you actually have to know what decade your guitar was built in to begin with.

Anyway, let’s start with how the main system works.

If you don’t have a serial number that looks one of the ones in the next section, then carry on to the following sections for the less common serial numbers.

Most Common Yamaha Serial Number System


The most common Yamaha serial numbers follow a system that uses 2 letters, followed by 5 numbers.

let’s look at an example of what this might look like – MM12022

From this we can tell that this is the 22nd guitar built on June 12 of either 1966, 1976, 1986, 1996 or 2006.

So, how does this work?

The First Letter

The first letter represents the year that the guitar was built.

The letters H to Q each represent the number that the year the guitar was built in ends in.

H = 1

I = 2

J = 3

K = 4

L = 5

M = 6

N = 7

O = 8

P = 9

Q = 0

But it gives no clue as to the decade so for each letter it could represent the following years.

First LetterYears
H1961, 1971, 1981, 1991, 2001
I1962, 1972, 1982, 1992, 2002
J1963, 1973, 1983, 1993, 2003
K1964, 1974, 1984, 1994, 2004
L1965, 1975, 1985, 1995, 2005
M1966, 1976, 1986, 1996, 2006
N1967, 1977, 1987, 1997, 2007
O1968, 1978, 1988, 1998
P1969, 1979, 1989, 1999
Q1960, 1970, 1980, 1990, 2000

I can only assume that this has been continued beyond 2010 because I haven’t been able to find any information for a different system but I can’t confirm this. If anyone knows please feel free to leave a comment in the comments section at the end of this post.

So, in our example we have an “M”, so it could have been built in 1966, 1976, 1986, 1996 or 2006 (and maybe 2016).

  • MM12022
Yamaha C40II Classical Guitar

The Second Letter

The second letter represents the month that the guitar was built. A similar number system is used but includes 3 extra letters (X, Y & Z) to represent 10 (October), 11 (November) and 12 (December).

Second LetterMonth
HJanuary
IFebruary
JMarch
KApril
LMay
MJune
NJuly
OAugust
PSeptember
XOctober
YNovember
ZDecember

In our example, M = June.

  • MM12022

The First 2 Numbers

The first 2 numbers represent the day of the month so this is pretty straight forward.

In our example 12 = the 12th day of the month.

  • MM12022

The Final 3 Numbers

The last 3 numbers represent the unit number that was built that day.

So, in our example 022 means that this guitar was the 22nd guitar built on that day.

  • MM12022

If your serial number follows this format and you want a faster way of deciphering it check out the serial number wizard at the link below:

>>Guitar Dater Project Yamaha Serial Number Wizard

Note: The Serial number wizard at the link above only works for serial numbers that follow the format above. If yours doesn’t you’ll need to keep reading to decipher it.

Yamaha C40II Classical Guitar

What if My Yamaha Serial Number doesn’t Follow This Format?


If your serial number looks nothing like this 2-letter, 5-number format, check out the other systems used below, your guitar might fit with one of these.

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).

Note: The following only applies to acoustic, acoustic-electric and classical guitars. There is a different system for electric guitars and bases.

Made in Japan Custom Shop 1966-1985

These were just sequential serial numbers from 001 up to 1042.

To work out the year you’ll have to take a rough guess. The closer to 001 it is the closer to 1966 and the closer to 1042, the closer to 1985.

Made in Japan Custom Shop 1986-1990

These serial numbers have 1 letter followed by 4 numbers.

The letter represents the month and follows the same system for months as the most common system above.

The first number represents the year.

The last 3 numbers represent the unit number.

For example: J7012

This would be a guitar built in March of 1987 and it was the 12th Unit made that day in the Japan custom shop.

The J is March as per the main system above and the year has to be 1987 since this system was only used between 1986 and 1990.

Made in Japan Custom Shop 1991-1996

This was a 2 letter, 3 number, then 1 letter system.

The first letter is the year and follows the same code as the main system above.

The second letter is the month and also follows the same system as the main system above.

The 3 numbers represent the unit number, but in this case the unit numbers started at 700 for some reason. So the first unit of the day wasn’t 001 but rather 701.

The final letter is an unknown internal code.

For example: IP703J

The example serial number above belongs to a guitar that was the 3rd guitar built in September of 1992.

Made in Japan Custom Shop 1997-2003

This is the same as for 1991 to 1996 with the following differences:

  • There is no internal code at the end
  • The unit numbers start at 001 instead of 701

For example: PP045

The example serial number here represents the 45th guitar built in September of 1999.

Made in Japan Custom Shop 2004-

This uses a 3 letter, 3 number, 1 letter system.

The first 2 letters represent the year in this case. So you do get the decade here.

The third letter represents the month as per the main system.

The 3 numbers represent the unit number.

The final letter is an internal code.

For example: QNK026C

This guitar in the example serial number was the 26th guitar built in April of 2007.

The Q represents an 0 and the N is a 7, meaning 07 for 2007.

Made in Japan Tenryu/Wada Factory 1946-1968

This is a 5 digit sequential system. There is no indication of year of production in this system.

Made in Japan Tenryu/Wada Factory 1969-1984

This is a nice and simple 6 digit system.

The first two numbers represent the year.

The Second two numbers represent the month.

The last 2 numbers represent the unit number.

For example: 790507

This is simply the 7th guitar built in May (05) in 1979 (79).

Made in Japan Tenryu/Wada Factory 1985-1986

For this short period there is also a 6 digit serial number but doesn’t show the month.

The first 2 numbers are the year.

The last 4 numbers are the unit number.

For example: 860102

This represents the 102nd (0102) guitar built in 1986 (86).

Made in Japan Yamaha Music Craft 1997-1999

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.

Made in Japan Yamaha Music Craft 1999-

The first letter is the year.

The second letter in the month.

The 3 numbers are the unit number.

The unit number starts at 200.

For example: PL225

This guitar was the 25th guitar built in May of 1999.

Made in Japan Yamaha Music Craft 2001-

This is a 3 letter, 3 number, 1 letter system as follows.

The first 2 letters represent the year following the same coding system.

The 3rd letter represents the month following the same coding system.

The 3 numbers are the unit number.

The last letter is an internal code.

For example: QJK033A

This would be the 33rd (033) guitar built in April (K) in 2003 (Q = 0, J = 3)

Made in Taiwan Kaohsiung Factory 1971-2001

This is an eight number system.

The first number represents the year.

The second and third numbers represent the month.

The fourth and fifth numbers represent the day of the month.

The Final three numbers represent the unit number.

Because there is only 1 number representing the year, there are possible duplicates using this system.

For example: 30914023

This example serial number was the 23rd guitar built on the 14th day of September in either 1973, 1983 or 1993.

Made in Taiwan Kaohsiung Factory 2001-

In 2001 the Kaohsiung Factory system changed to a 3 letter, 6 number system as follows:

The first 2 letters represent the year.

The 3rd letter represents the month.

The first 2 numbers are the day of the month.

The last 4 numbers are the unit number.

For example: QLY180122

The example serial number represents the 122nd guitar built on the 18th of November 2005 (Q = 0, L = 5).

Made in Indonesia YMMI (Yamaha Music Manufacturing Indonesia) 1990-1996

For this period in this factory they used an 8 digit serial number.

The first number is the year.

The 2nd and 3rd numbers are the month.

The 4th and 5th numbers are the day of the month.

The final 3 numbers are the unit number.

For example: 30814023

The example serial number represents the 23rd guitar built on the 14th of August in 1993.

Made in Indonesia YMMI 1997-1999

This is the same as for 1990 to 1996 except there are 9 numbers. The last 4 (instead of 3) represent the unit number, the rest are the same.

Made in Indonesia YMMI 2000-

This is the same as for 1997-1999 except there are 10 numbers. The first 2 numbers represent the year (instead of just 1 previously).

Made in Indonesia YMMI 2001-

The YMMI changed to a 3 letter, 6 number system in 2001 as follows:

The first 2 letters represent the year.

The 3rd letter represents the month.

The first 2 numbers represent the day of the month.

The last 4 numbers represent the unit number.

For example: QKZ160062

The example serial number above represents the 62nd guitar built on the 16th of December 2004 (Q =0, K=4).

Is this Everything?

Apparently, some could even fall outside of this range. If your serial number doesn’t seem to match any of the above, you’ll need to contact Yamaha to see if they can tell you about your serial number.

Hopefully this will help most people to find the information for the serial number of their Yamaha guitar.

Yamaha Guitar Serial Number FAQs

How do you read a Yamaha guitar serial number?

Locate the serial number on your Yamaha guitar and consult this blog post. If your serial number doesn’t seem to match any of the above, you’ll need to contact Yamaha to see if they can tell you about your serial number.

Where is the Yamaha guitar serial number?

This information is usually found inside the sound hole of your guitar. It will usually be found next to the serial number and will say “made in..” and then the country that the guitar was built in (either Japan, Taiwan or Indonesia).

What is the date on a Yamaha guitar serial number?

The first letter or letters of the serial number typically represent the manufacturing year, and the subsequent letters or numbers may indicate the manufacturing location and other production details. By deciphering the serial number and referring to Yamaha’s documentation or contacting their customer support, you can determine the manufacturing year of your guitar.

Where is the serial number on a Yamaha electric guitar?

On a Yamaha electric guitar, the serial number is typically located on the back of the headstock. The headstock is the portion of the guitar located at the top of the neck, where the tuning pegs are situated. Look at the backside of the headstock, and you should find the serial number engraved, stamped, or printed there.

In some cases, the serial number may also be found on a sticker or label on the back of the headstock. Occasionally, it can be located on the neck plate or on the back of the guitar body, near the neck joint. However, the most common placement for the serial number on a Yamaha electric guitar is on the back of the headstock.

Nate is just your average (above average) guitar player. He's no Joe Satriani, Jimi Hendrix or Jimmy Page - wait this site is about acoustic guitars (sorry) He's no Django Reinhardt, Chet Atkins, or Michael Hedges, wait? who!? He's no Robert Johnson, Eric Clapton or Ben Harper - more familiar? Anyway you get the point :-)

  1. I have a Yamaha FG-160, having trouble with the truss rod,I cannot straiten the neck.I have turned the nut clock wise as far as it will go.Any suggests.

    1. Hi Don

      If you’re unable to turn it any further I wouldn’t force it as you could do damage. I think the best option is to get a guitar tech/luthier to take a look at it for you.

      1. I have a made in Japan s/n 1588339 model FG-75 Nippon gakki. Any info you may have would be appreciated.

        1. Hi Paul

          Thanks for your message.

          That number doesn’t seem to fit any of the serial number systems that I know of, unfortunately. It seems that FG-75s might be one model that didn’t necessarily follow any of these systems – here’s someone else searching for this (though their serial number is only 5 digits!) – http://www.harmonycentral.com/forum/forum/guitar/acapella-42/1313586-

          I think your best bet would be to contact Yamaha and see if they can provide you with more info.

  2. Buena Tarde.
    Tengo dos guitarras Yamaha nuevas, creo que son del a?o 1961 o anteriores, una es la C40 y la otra es la C 60 los n?meros de serie que aparecen son 61029058; 71010006 respectivamente, quisiera que me ayuden para saber su valor.
    Lo mismo tengo una guitarra nueva Brasilera Giannini, a?o 1956.

    Gracias de antemano.

    Good evening.
    I have two new Yamaha guitars, I think they are from 1961 or earlier, one is the C40 and the other is the C 60 the serial numbers that appear are 61029058; 71010006 respectively, I would like you to help me to know its value.
    The same I have a new Brazilian guitar Giannini, year 1956.

    Thanks in advance.

    1. Hi Alvaro

      Thanks for your message. I have added an English translation to your message as I don’t speak Spanish. I hope this translation is accurate.

      Unfortunately I don’t do valuations for guitars, and those serial numbers seem to be numbers that you might have to contact Yamaha to get information on them.

      The only serial number systems that those numbers seem to fit into would be the following: But since you think they’re from around 1961, then these are probably not the right ones:

      ~ Made in Taiwan Kaohsiung Factory 1971-2001
      If it was under this system, it the numbers would be:
      61029058 = The 58th guitar made on the October 29th of either 1976, 1986, or 1996
      71010006 = The 6th guitar made on October 10th of either 1977, 1987, 1997

      ~ Made in Indonesia YMMI (Yamaha Music Manufacturing Indonesia) 1990-1996
      If it was under this system, it the numbers would be:
      61029058 = The 58th guitar made on the October 29th of 1996
      71010006 = can’t be a part of this system

      You can see how their serial number system is very confusing and how its hard to tell from a lot of the systems they used and a lot of duplicates. I think your best option is to contact Yamaha to see if they know.

      Hope this helps

  3. Hello, I’m just trying to find out more information on my guitar but the serial numbers and the instructions above just don’t add up lol. Any help would be appreciated. It’s an F325D and the serial is HLN0475W

    1. Hi Jamie

      Yeah, that number doesn’t seem to fit into any of these systems. The only one that it’s close to is the Japan Custom Shop 2004 to present. That system uses 3 letters, then 3 numbers, then another letter. Your number is 3 letter, 4 numbers, then another letter. If it was made in the Japan Custom Shop, then it would be:

      Made in July 2015 and the 475th guitar built in that factory in that month.

      But definitely couldn’t say for sure. I think your best bet would be to message Yamaha with your serial number and ask them. There are serial numbers that don’t fit any of these systems – a confusing, ever changing serial number system for sure!

      Hope this helps

  4. Hi, I’m Dave, and I’m having a fair amount of difficulty deciphering these Yamah codes. I have a FG430A I believe, with a serial # of 20820627 if you can, please help

    1. Hi David

      It looks like this was either “Made in Taiwan Kaohsiung Factory 1971-2001” or “Made in Indonesia YMMI (Yamaha Music Manufacturing Indonesia) 1990-1996” – both of which used an 8 digit serial number system.

      Because there are duplicates used in these serial number systems it’s hard to know the precise year, unless you know which decade it’s in.

      If it’s part of the “Made in Taiwan Kaohsiung Factory 1971-2001” then it would be either:

      The 627th Guitar built on August 20, 1972
      The 627th Guitar built on August 20, 1982
      The 627th Guitar built on August 20, 1992

      If it’s part of the “Made in Indonesia YMMI (Yamaha Music Manufacturing Indonesia) 1990-1996” then it would be:

      The 627th Guitar built on August 20, 1992

      Hope this gives you more to go off

  5. Hi,
    Can someone help me please. I have a six string Yamaha. Inside there is a brown label with a black scroll Design motif and G-60A written in gold, the serial number inside is.
    T0096752

    1. Hi Bob

      That serial number doesn’t seem to fit any of the systems described here – as far as I know the G-60A is a classical guitar – but couldn’t say when it was built. This – https://reverb.com/ca/item/1431986-yamaha-g-60a-classical-acoustic-guitar seems to suggest that at least some of those models were built in the Taiwan Factory. But I couldn’t tell you when. If anyone knows more, feel free to chime in. Otherwise, your best bet is to contact Yamaha and ask them.

      Hope this helps

  6. I have a yamaha fg-110 red label with 7 digital ser#1055988. It also has a person’s head carved in the head stock can you help with identity of this guitar thanks Roy

    1. Hi Roy

      Thanks for your message.

      Unfortunately I haven’t been able to match that number to any of the serial number systems here. I’m also not familiar with any Yamahas with a persons head carved into the headstock. Your best bet is to contact Yamaha and see if they can identify it.

  7. My Yamaha, certainly pre-1970, has the number 1419682 on the inside of the block where the neck attaches. Can’t figure out what that means – have to assume it is the serial number. Any help welcome.

    1. Hi Cecil

      Thanks for your message.

      I can’t seem to match that up to any of their serial number systems unfortunately – they seem to have a very complicated way of doing it and many numbers that seem to fall outside of any system. I would contact Yamaha and see if they know – maybe send them a picture of the guitar and the serial number (if you can get an angle that can take a picture of the serial number).

  8. Good day i have a yamaha CG100A made in Taiwan Koahsiung factory with serial nr O1009175 can you please date it for me

    1. Hi Joy

      Thanks for your message. Assuming that this is supposed to be 01009175 as opposed to O1009175 – i.e with a zero rather than the letter “O” at the start, then it would be, by my calculations:

      The 175th guitar made on October 9 in either 1980, 1990 or 2000.

      Unfortunately the serial number system for guitars made in the Kaohsiung Factory between 1971 and 2001 didn’t specify which decade.

      If it is an “O” at the start and not a “0” then I’m not sure.

      Hope this answers your question

  9. Great page and thanks for collecting so much information! I have an MIJ LS-500 with the serial PX341J.

    Going by the above that dates it to Oct 99, but is the number date related, or is it the 341’st guitar made that month? It seems to fit most closely to the MIJ Music Craft, but with the additipn of a J.

  10. Any idea what year my Yamaha is?…only number I could locate was at base of neck…visable in hole of acoustic guitar…it’s a FG-411CE # 60917659…made in Taiwan. Thanks!

    1. Hi. From the Yamaha 8-digit dating system (see above), your guitar was the 659th of its range, made on 17 Sep – made in either 1996, 2006 or 2016 . Hope that helps

    2. Sorry Bill… a correction – your guitar would have been the 659th made in that factory, on 17 September in either 1976, 1986 or 1996

  11. Hello,
    I have looked all over with different sites and am hoping maybe you can help.
    Your listing is good but mine is also different.
    It is stamped on the head-stock “Yamaha EG112”
    and on the back a Indonesia 10328042.
    Any help would be appreciated.

  12. Thanks for the very useful advice in determining the age of a Yamaha guitar….. I have one of the first Yamaha CJ838S accoustic guitars – fabulous instrument solidly played and gigged since purchase – sound just gets better and better and never adjusted….. Back when I bought it , it cost me GBP225 – a lot of money then when I bought it – which I thought was around 1976…. Thanks to your info, I now know it was purchased around 1980, serial number is : 80602404 – which tells me it was the 404th one made on 2/6/80. This surprises me as it would have been purchased not long before I got married, the following year. Given that finances were tight, wonder how I managed to get my fiancee to allow me to buy it ….. !!!???!!! It has given me some nearly 40 years of playing pleasure….. no gigging now, just playing at home….. but still makes my playing seem a lot better than it actually is…..

  13. Help…I have a Yamaha acoustic made in Taiwan with the coding of FG-441CE TBS and the serial of 58629482. can you help on the date of manufacture please.

  14. Good Afternoon Nate,

    I have a CJ-838Sii with the serial #112220834, which is odd since it has 9 numerals instead of 8. The sticker badge says “Made in Taiwan Republic of China”. Yamaha Japan tuners. Any ideas?

    Thanks,
    Eric

    1. Eric.. Re yourt Yamaha CJ838S – serila 112220834. From my own same make instrument, would suggest you interpret your serial as: manufactured, 1981/1991/2001, the 834th instrument made at the factory on 22 Dec ?

  15. Any idea what year my Yamaha is??only number I could locate was at ?visIble in hole of acoustic guitar?it?s a F 210

  16. Sir, I have a guitar with the numbers OLN0087S a Yamaha and I do not know how to figure what the worth is of this guitar. My husband passed and left me with two this one and a Fender plus a Japanese one also. Can you help me find out what the worth of this one is. I have a hard case to keep it in and it is in excellent shape with no scratches or anything on it. I want to sell these and do not want someone to cheat me on these items. Thanks Susan

  17. Hey there I too have a letter M,the next I think is letter I so the whole thing is MI07299 I am intrested to see year and any other info

  18. Hello, I just got my fg-410e and i am confused about the dating, since you showed so much knowledge about it i would appreciate your help if you could maybe give me some more details about its age. Serial is 50606068 and the sticker inside is oval(like an ellipse) and it says yamaha
    FG-410E
    made in taiwan
    Republic of china.
    Thanky very much

  19. I have just bought a Yamaha 6-string acoustic with the serial No. FG-420-L, made in Taiwan.
    Any idea of its age, please?

    1. That is the model number not the serial number. Check in the sound hole at end of neck where trust rod adjustment is.p

  20. I have a early 70?s Yamaha classical guitar model # C-180 It has a 5 digit serial #70311 I think, with a red line to the right of the serial number. Anyone have any info on it?

  21. Hi i have a nippon gakki red label fg230 12 string ,no made in…..8 digit serial….it has a K inside a circle ink stamped above the label on the centre strut …this must mean( imo )the Kaohsiung Factory also before the digits, it has a chinese/japanese character stamped in ink.it also has a sticker on back of headstock saying made in japan, all very confusing…hope this helps….regards

  23. If your Yamaha guitar has an 8 digit serial number, based on its general age or when you purchased it, you should be able to date it. From my CJ838S serial number, I know it was generally manufactured from late 70’s-80’s , so my serial number – 80502171, given when I was gigging, makes it the 171st guitar produced at the factory on 2 May 1978?.. making it one of the first made and sold…. Still a fabulous instrument whose tone gets better every year (even if its owner doesn’t… !!!??)???.

  27. Hello.
    I appreciate this comprehensive listing, but still can’t seem to determine when my guitar was manufactured.
    It is an FG-180 with a reddish/orange label that says Nippon Gakki.
    There is a six-digit number, 887554, on the inside, near where the neck attaches.
    Any help in identifying the the manufacture date would be appreciated.
    Thank you.

  31. Hi, great info site this, I have a Yamaha F-310 was given to me, low end I guess, but surprisingly sounds good for a low end guitar, label, Indonesia, 8 numbers 80730042, when I check it should relate to 90-96 having 8 numbers, but this starts with 8, so I’m thinking the year ends like 98 ??, now I think the 97-99, But those are 9 number , and so cannot work it out which year, any help on this appreciated, forgot to mention, open backed tuners on this model …. Thanks

  32. hello i have a yamaha fg 180
    red label nippon gakki
    serial 735920 can anyone please tell me how old this guitar is?

    1. Hi… I played an FG180 back in late 60’s….. So because of the models’ history, and your serial no 735920, suggest it was made in 1973, on 9 May, and was the 20th guitar made on the day. Hope that helps..

  33. I have a G 245 S ii bought new in the eighties from a musical instrument shop. There is no serial number anywhere (believe me I’ve looked). It’s made in Taiwan, the label and build quality all check out perfectly. Anyone know why there is no serial number?

  34. I have a red label Yamaha FG180 made in Japan……I bought it second hand in the mid 70s…….the serial no is1132230. Does anyone know the date of manufacture. Reading other comments I suspect not!! Cheers.

  36. FG 200 number on the Bridge A0506170 number on the neck 0521990. Inside label Made in Taiwan under that Republic of China. What’s it all about?

    1. Hey there CB.

      I’m no expert on the topic of serial numbers from Yamaha, hence why I religiously referred to a couple of in-depth sources (https://yamahavintagefg.com/yamaha-fg-serial-numbers-interior-markings-and-labels-1966-to-1981/ & https://www.yamaha.com/yamahaguitars/AcousticGuitarSerialNumberSystems.pdf) on the subject when I wrote this article – sources which happen to be written by a representative of Yamaha.

      Hope these sources can also be of help for you, CB!!
