AVS (Address Verification System) is a system that attempts to match the billing address that your customers enter in the Billing Address fields during checkout. When the credit card entered is authorized, AVS checks to see if the cardholder's address entered during checkout matches the address information on file with the issuing bank. AVS returns codes that match AVS Rules set by you about the address such as if the address and or zip/postal code match.
AVS is one of the informational tools in Risk Tools that helps merchants make decisions about which transactions to flag for follow-up with the customer or issuing bank. AVS allows the merchant to set up rules to flag transactions based on address and zip/postal code.
AVS Rules are based on the codes returned by the Address Verification System (AVS). The codes used by AVS Rules and the default settings are outlined in Table 1:
|AVS Code||Default Setting|
|Address OK, Zip/Postal Code wrong||YNA, YNB||Flag|
|Address wrong, Zip/Postal code OK||NYZ, NY, NYW, NYP||Flag|
|Address and Zip/Postal code wrong||NNN, NNC||Flag|
|System is not available||XXR||Flag|
|Verification is not on card||XXE, XXG, XX||Flag|
Address and Zip code match
|YYY, YY, YYX|
Address and Postal code match
|YYD, YYF, YYM|
Based on the codes returned for a particular credit card authorization, you can set the AVS Rules to automatically flag orders. Flagged orders will appear with a "pending review" status on the Order pages. The AVS code information will also appear with the credit card information in the Payment section of the individual order screen.
To set AVS Rules:
Note: You must have your online payment processing set to perform real-time authorizations in order to use AVS and CVV Rules to flag orders based on response codes as part of Risk Tools. Without real-time authorization, Risk Tools cannot check the address and card verification value provided by customers during checkout. View instructions for enabling real-time authorization of orders.
