Address Verification System (AVS)

 Top  Previous  Next

This one character field contains the Address Verification System (AVS) result code. An AVS result code can provide additional information concerning the authentication of a particular transaction for which cardholder address verification was requested. An AVS result code of "0" will be returned in the response message when no address verification has been requested. The value returned should be stored and submitted as part of the batch settlement. The valid AVS codes are listed in the table below. Please see the ResponseCode property for a more detailed list of ResponseCode and ResponseAVS code combinations.
