Our BIN is registered to Wirecard (our issuer in the UK) but it was previously in use by Westpac. Some merchants have not updated their BIN tables to reflect this change.
However, if you can provide details of the merchant where you had issues we can inform MasterCard® who will ask them to update their BIN information.
