Accordiola began production in Camerano, Italy, on June 5, 1937, and can be considered for completion in 1985 when another accordion manufacturer, Nello Mengaschini, bought Accordiola. Nevertheless, the history of the Accordiola brand is unclear. Nowadays (2020) Accordiola brand is produced at least in Belgium. Those Accordiolas that do not have an indication of Italian origin are marked as Belgian.
