Fraud Filter Reference
High-risk Payment Filters
E
How does the filter protect me?
Some products are attractive to fraudsters (especially popular products with high resale value
like computers or televisions). The Product Watch List filter gives you the opportunity to
review transactions involving such products to ensure that the order is legitimate.
High-risk Payment Filters
High-risk Payment Filters identify transactions that show billing/shipping discrepancies or an
indication that someone other than the legitimate account holder is initiating the transaction.
AVS Failure Filter
What does the filter do?
Address Verification Service (AVS), compares the street number and the ZIP code submitted
by the customer against the data on file with the issuer.
The AVS response is composed of a Y, N, or X value for the customer’s street address and a Y,
N, or X value for the ZIP code. For example, the response for a correct street number and an
incorrect ZIP code is YN.
If AVS information is not submitted with the transaction, then the response is NN.
AVS checks only for a street number match, not a street name match, so 123 Main Street
returns the same response as 123 Elm Street. The “USPS Address Validation Failure Filter”
on page 93 validates the address information
NOTE: .
The specified action is taken whenever the AVS response does not meet the criterion that you
specified.
IMPORTANT: The AVS Failure filter performs the action after the transaction is processed.
This means that, if set to reject, the filter rejects the transaction after the
transaction is authorized by the processor. To charge the customer for such a
transaction, you must resubmit the transaction data.
