Where to find the serial number on a Heintzman & Co. piano

  • Upright piano: open the top lid and look at the cast-iron plate near the tuning pins, usually on the left or right side.
  • Grand piano: look on the plate near the tuning pins, under the music desk, or on the soundboard beside the plate.
  • It may also be stamped on the back of the case, under the keyboard, or on the keyframe — check with a flashlight.
  • Ignore model numbers and patent dates: the serial number is usually 4 to 7 digits long.

Good to know

  • The year in the chart is when the piano was manufactured, not when it was first sold.
  • Our Heintzman & Co. records cover 1867 to 1980. If your number is outside this range, the result shows the closest year we have.
  • Pianos built decades ago often need more than a tuning: worn hammers, loose tuning pins and dry wood are common. A technician can tell you what yours needs.
