This solution is not 100% correct. The location code can be letters and digits. The second character can have a meaning (if 0,1 or 2), but all other digits are also valid and indeed are used.

The RegEx therefore has to be changed to: /^([A-Z]{6}[A-Z2-9][A-NP-Z1-9])(X{3}|[A-WY-Z0-9][A-Z0-9]{2})?$/

Commenting since I also found this via search. The source at jquery-validation/additional/bic.js also changed this already.

will the above code work for Euro countries ??
