The serial number on YAMAHA VERTICAL PIANOS is stamped on the gold colored plate on the inside of the piano as illustrated in the vertical piano picture. The serial number can be seen by opening the toplid of the piano and looking inside. Yamaha Pianos produced for the North American market have been manufactured in 4 locations.
1. The brand name of the piano.
Note: Some pianos will have more than one name for the manufacturer. For example: 'Hamilton' by Baldwin or 'Cable Nelson' by Everett. To make sure that you have all of the information you will need, open the lid of your piano and check out the name or names engraved or printed on the plate. Do NOT trust the name on the outside of the piano since in could have been refinished and a different name added.
2. The serial number (NOT the model number) of the piano.
To locate the serial number on a vertical piano, open the top and look inside. Almost all of them include the serial number on the plate in a small 'window' near the tuning pins. The number will usually be a 4 to 7 digit number, but may include a letter or two. If you can't locate it here, look inside to the far left or far right as some manufacturers attach it there on a small piece of metal. It may be stamped in the wood under the lid, or as a last resort, pull the piano away from the wall and look on the back.
To locate the serial number on a grand piano, take the music desk off. It's usually stamped on the pinblock here. Also look on the soundboard, many of the manufacturers will include it inside one of the 'windows' in the plate.
After you have located the manufacturer's name and the serial number, you have two options.
