Frequently asked questions
Is PianoLookup free?
Yes, completely free, no registration or email required.
Where is the serial number on a piano?
On an upright piano, look inside the top lid for a number on the metal plate or near the tuning pins. On a grand piano, it is often on the metal plate under the lid. The location varies by maker; use our Find Serial Number guide for more help. Do not confuse the model number with the serial number.
How accurate is the estimate?
Accuracy depends on the manufacturer and the available records. A serial number may identify a production year or a range of years; some dates are approximate. Overlapping sequences and different factories can produce several possible matches. Check the source and serial range shown with your result, and see our Methodology page for details.
What if my brand isn't listed?
Check the spelling on your piano and browse the full brand directory for alternative names. If the brand is still missing, PianoLookup cannot provide an estimate for it. Try the manufacturer, if it still exists, or a piano technician who has access to historical records.
Does the serial number tell me what my piano is worth?
No. A serial number helps identify age and sometimes manufacturing origin, but it does not establish value. Condition, model, maintenance history and local demand all matter. A piano technician or appraiser needs to assess the instrument for a valuation.
