How old is my Steinway?

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

On Steinway upright pianos the serial number can be located on top of the wrestplank above the cast iron plate when you open the lid.

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

Steinway Serial Numbers by Year Manufactured

Please Note: Serial numbers represent the approximate beginning serial number for the year of production for New York and Hamburg pianos.  Steinway Serial numbers for some early production may span more than one year.

There’s a nifty new lookup feature at Steinway.com to discover additional details about your piano’s serial number
(note we’ve found not ALL serial numbers are found).  See https://www.steinway.com/pianos/serial-lookup#/.
