What is AVS?
The Address Verification Service is a tool that allows you to check if the address of a credit card is linked to the person claiming to own that credit card. The AVS tool is usually provided to you by your credit card processor and can be used whenever you're processing a keyed-in transaction (such as online or through a Virtual Terminal).
AVS is one of a number of fraud prevention tools that can help prevent stolen credit cards from being used for purchases at your business.
How Does AVS Verify The Address?
When a customer has finished adding items to their cart on your site and is ready to pay, they are brought to a payment form. On this form, they are asked to enter their credit card payment information, along with their billing address.
While the credit card transaction is being processed, the system will also compare the billing address entered by the user at checkout, with the address linked on file at the customer's credit card bank (the issuer). As part of the transaction response, an AVS response code will be returned. Examples of these could be “X” for “Exact Match”, or “N” “No Match”.
Keep in mind that the AVS result doesn’t actually impact if the transaction is approved or declined - it only gives you the result of the address. That means that if the customer enters an incorrect address, the transaction can still be approved by the bank. It is up to you as the merchant to decide, based on your comfort level, whether you should ship the item or cancel their order and refund the transaction.
AVS Increases Your Security.
AVS is just one of many tools that merchants can use to review orders and prevent fraud. When your business combines an AVS system with other security measures like requiring a CVV on your credit card transactions and even implementing a fraud detection tool (like Helcim’s Fraud Defender), you reduce the risk of exposing your business to fraudulent orders.
