The first two digits should be the year it was made,but after that who knows.You might try writing Washburn and see if they can help.If you own one you either love it or hate it from what I have seen and heard,mine was made in China and it's one of the best guitars I own.Some are made in Indonesia and I think these are the ones that have the most problems .I have an Indonesian Squier Strat that I am very happy with so who knows?I hope this post was of some help to you.
