HOW OLD IS MY STEINWAY?

To determine the age of a Steinway piano we need to first locate the serial number.

 

Steinway Upright Piano Serial Number Location

3830-serial-number-upright

On Steinway upright pianos the serial number can be located on top of the wrest plank (pinblock) above the cast iron plate when you open the lid.

Steinway Grand Piano Serial Number Location

3829-serial-number-grand

On Steinway grand pianos the serial number can be found on the cast iron plate between the tuning pins above the keyboard.
