Our Canadian customer getting AVS Response code :N when trying to do payment using moneris payment gateway. His card type is MasterCard. As per our application log payment message is "APPROVED * APPROVAL =" but AVSResultCode is "N" and as per moneris documentation AVSResultCode "N" means "Neither address nor postal code matches" because of this AVS Result resonse code we are rejecting this transaction. We think this might happened because customer may entered zip code with blank space e.g N9E 4S2.
Please suggest that in which condition of zip code code is invalid or AVSResultCode provide Rejected response code?
