To find the exact age and origin of your Yamaha guitar, the best approach is to combine the serial number with the "Made in" label. Yamaha has used over 29 different serial number formats since the 1960s, many of which recycle every 10 years, making the country of manufacture essential for accurate dating. 1. Locate the Serial Number
Serial number locations differ significantly by guitar type:
Acoustic & Classical: Usually found on the label inside the soundhole, stamped on the neck block (look inside the soundhole toward the neck), or stamped on the brace under the fretboard.
Electric & Bass: Most often stamped into the back of the headstock. Hollow-Body: Printed on a label visible through the F-hole. 2. Decode the Format
Most modern Yamaha serials (post-1980s) use a letter-to-number code where specific letters represent the month or year digits. The Letter-to-Number Key: Digit Common Format (Taiwan/Indonesia, 2000s): QIM180013 Q & I (Year): 0 and 2 = 2002. M (Month): 6th letter = June. 18 (Day): 18th day. Acoustic Format (8 Digits): 20918022 1st Digit (Year): 2 = 1992 (or 1982, 2002). 2nd & 3rd (Month): 09 = September. 4th & 5th (Day): 18 = 18th. 3. Dating Vintage Yamahas (1966–1984)
Early models can be harder to date because they often used sequential numbering rather than date-encoded formats.
1966–1971 (Japan): Often 6 or 7 digits; these are sequential and do not directly encode the date.
Internal Date Codes: Check the inner sides of the guitar for a hidden ink-stamped code like 45.12.28. The first number refers to the Showa era year. (e.g., 45 = 1970). Best Lookup Tools
