Grand Piano Serial Numbers
Where Are They Found? ...

Here are the TOP FIVE places to locate the serial number of your BABY GRAND or GRAND piano:

(See this link for a detailed picture of where to look)

Note: You may have to remove the (1) music desk first and (2) gently clean out any dust from your piano's plate [using a soft dry cloth + vacuum hose] before you can find these numbers.

Serial number locations are found:

1) On the piano’s cast iron plate, near the tuning pins, as you face the keys. Look to the right or to the left.

2) The Capo d'astro bar. Located on the right, this acts as a 'bridge' to the 'beams' of the cast iron plate.

3) On the piano's soundboard (see link above for a diagram).

4) On a metal plate underneath the piano's top lid, near the strings and soundboard.

5) Immediate interior [front]: On the back of the [a] keyslip (long wooden ledge, runs along the front/bottom of the piano's keys. The serial number is often hidden and stamped on the other side, facing the keys). On the front of the [b] action frame (after the keyslip is removed), or stamped on [c] one or both of the cheek blocks, viewed to the right and left of the piano's keyboard.

On older pianos, you may find 3-5 screws, underneath the keyslip, that will need to be removed (or, simply lift up, if no screws are present) to view the action frame. The serial number may be stamped on the front of the frame's wooden base, immediately under the keys.

To the right and left of the keys are two end cheek blocks, which are each secured down with a giant bolt or screw, which passes through the piano's keybed, both of which must be removed, to access the interior of the piano (see video, above).

Caution: When unscrewing and removing the cheek blocks, do not mistake the piano's leg screw/bolt, with the cheek block's screw/bolt.

Also, be careful not to drop the cheek blocks once they are removed, which can gouge and permanently damage the piano's case, and the block's delicate condition.

To recap: the piano's serial number may be hidden on the back of the piano'skeyslip (immediately in front of / below the keys), on the action's frontkeyframe, on the cheek blocks (each side), or within the action itself, once removed from the piano.
