The postal code does not match, is not verified or is not provided.These rejection checklists often suggest rejecting a request based on the following: Traditionally, a payment processor will provide basic checklists to merchants so they can quickly decide which order to reject and which to accept. This helps merchants control their risk levels while maintaining positive relationships with their processors and issuers. Typically, depending on the level of risk for each transaction, a merchant can decide on which type of AVS code they want to accept or reject. This can include three options: Match, partial match and mismatch (see the chart below for an explanation of each AVS mismatch code). Once the transaction gets initiated, the merchant receives a particular AVS code signaling the type of match. To complete the transaction request, an issuer’s system has to be able to quickly and adequately verify the order details against the payment details they have on file with that specific cardholder. If authorized, an issuer will approve the processor to authorize the transaction request. With each order placed online, the payment processor sends a request for an AVS approval to determine if there is an address match. These filters are complicated to understand as they vary by issuer and card type. When a merchant receives an AVS mismatch alert, that doesn’t always mean the purchase is fraudulent.

By automatically setting AVS mismatch filters, merchants can flag suspicious transactions before they occur. This system helps merchants, payment processors and card issuers proactively fight fraud. To do so, an AVS validates the numbers in the billing address with the card address on file to ensure the cardholder is making the purchase. It’s much harder to mediate the problem after fraud occurs, which is why AVS filters are useful. To cut down on credit card fraud, card issuers and banks have implemented more sophisticated measures that can flag suspicious transactions before they occur.
