Finding out the age of a Yamaha Piano can be a complex task…
Every Yamaha Acoustic Piano ever produced has its own unique code called a serial number. This code is located on the top right hand side of the Cast-Iron Plate and is commonly used by prospective buyers and sellers to ascertain the exact age of an instrument for resale purposes.
Whilst there are many index tables available online to match these numbers to corresponding dates, there’s a few things to remember before doing so.
Yamaha Pianos have been produced in many factories located all over the world. In the last 30 years, each of these factories have had their own unique system for serial number allocation,
South Haven, Michigan
Milton Keynes, London
Furthermore, the Grey Market Piano business has seen a cross pollination of Piano models sell to markets where they may have never been sold new. Not knowing the country of manufacture can make for difficultly matching the right number to an Instrument.
The key to accurately dating any Yamaha Pianos age is to look for the production number instead of the serial number.
The production number is usually 8 digits long and located at the end of the aluminium action rail inside the right hand corner Piano. The first two digits of this row of numbers indicates the year of manufacture. For example,
This Yamaha C108 has a serial number of 4934078. The production number on the rail is 90552303. The first 2 digits (90) tell us that this Instrument was made in 1990.
This numbering system is ubiquitous for all models and assembly plants and provides a much quicker system for accurately dating an Instrument.
