Failed AVS Check: Ship the Order or Not?
A billing address that does not match is a warning, not a verdict. Here is how to read it before you pack the box.
The order looks fine. Good basket, normal amount, a name that sounds like a person. Then the payment detail says the address check failed.
What the check actually compared
The Address Verification System is a service that checks if a billing address matches the address of a credit card cardholder. It looks at the billing address only. The shipping address is a separate question, and you have to answer that one yourself.
AVS is a widely used fraud-prevention measure for card not present transactions, such as online payments or Mail Order/Telephone Order payments. That is your whole store.
A mismatch is not a confession
AVS checks can fail for legitimate payments. People move and forget to tell their bank. Apartment numbers get typed three different ways. The card is fine and the customer is real.
A failed CVC or postal code check can indicate the payment is fraudulent. Can, not does. So treat the result as one signal among the others on the order.
Read the rest of the order
Put the AVS result next to everything else you can see. Is the shipping address a freight forwarder? Is this a new customer buying your most resold item in bulk? Did the same card fail twice before it went through?
Those forwarders turn up in refund abuse too.
One soft signal is a phone call. Three together is a cancel.
Decide, then write the rule down
Based on the AVS response, you can decide to accept, make an exception, or cancel a transaction. Whatever you pick, pick it the same way next time. Some tools can do it for you. When the AVS check results in a mismatch, you can trigger a risk rule that holds the order.
Collect the CVC, postal code, and billing address for every payment, so the check always has something to compare.
