Paolo Soprani serial numbers.

Paolo Soprani is the name at the root of the Italian accordion industry. There are no company records to date an instrument by serial, but Paolo Soprani left unusually rich era markers: badges and exhibition medals, the “Cav.” and “Comm.” titles, and the evolution of the grille — a dating language the museum and forum communities have mapped out.

The first Italian accordion house.
Badges and medals tell the era.

Frequently asked
Does this archive date Paolo Soprani instruments?

Paolo Soprani serial numbers are not a date key — company records are not available. Dating is done from badge and medal eras, titles, and grille styles. See the dating guide.

Where is the serial number on a Paolo Soprani instrument?

The exact spot varies by era and instrument type — the serial number guide walks through the common locations.

What if my Paolo Soprani serial number is not found?

Recheck the characters exactly as marked, including any letters and leading zeros. Letter-prefixed numbers often belong to student or non-domestic lines that cannot be dated from the number. Some production periods may simply not be covered yet.
