ResponseAVS Property

Contains the Address Verification System result code.

Data Type

String

Default Value

Remarks

This one character field contains the Address Verification Service (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 for later retrieval, as it may be required when voiding or refunding a transaction. Valid AVS response codes are listed below, and are identical across all Gateways (note that some gateways do not return an AVS response).
