GOOD, BAD, STREET, and ZIP are Address Verification Service (AVS) response codes.
AVS is a service provided by the payment brands that determines the match or partial match of the consumer's address information. The responses are returned to you during the authorization process via your transaction processing software and/or hardware and can help you determine your next action (e.g. approval, exception, or decline).
Please note that your transactions will not decline automatically, even if the AVS response returns something other than GOOD.
If you want to set up automatic transaction handling based on the AVS response contact technicalsupport@fortispay.com to change your settings.
