This tool will decode the serial number of your Yamaha grand piano or Yamaha upright / vertical piano to show the year and location of manufacture. It works by firstly decoding the Yamaha factory code to see where it was made and then comparing the rest of the serial number with records for the first and last manufactured pianos in each year from each factory. It covers Yamaha pianos made from 1917 to 2012 in all 6 factories (Hamamatsu Japan, South Haven Michigan, Hangzhou China, Thomaston Georgia, Jakarta Indonesia, Taoyuan Taiwan).
Enter your Yamaha piano's serial number. It can normally be found somewhere on the piano's gold plate.
