How to use this serial-number series
Use this page when the factory, production series or serial prefix matches your piano. The main Yamaha lookup checks all known Yamaha series automatically.
Why separate production series?
Some manufacturers used different serial sequences for factories, countries, instrument types or letter prefixes. Keeping those systems separate avoids forcing unrelated numbering into one chart.
