The serial number on a Wurlitzer piano corresponds to the year in which it was made. A Wurlitzer piano made in 1903 has a serial number starting with 1910. After 1940, serial numbers start at 195000.
Serial numbers on Wurlitzer pianos can be placed in a few different places. When lifting the lid, the serial number may be stamped on a small, golden plate. It could be located on the back of the piano, near the top of the frame or on the piano's soundboard. Wurlitzer pianos were made in America starting in 1880. In 1995, Baldwin Piano and Organ Co. purchased the Wurlitzer name.
