The reason they need to do this is because FMIC and the international Fender/Squier distributors have different warranties and totally separate support systems including service centers.Our serial number guide shows approximate date of manufacture.For all dates, you will need to look at the construction technique and components used to get a more precise idea of the date of manufacture.
