AVS Response Codes


What is AVS?

The address verification service (AVS) is offered as part of the Visa, Mastercard, Discover and Amex network.

The AVS response will not impact the approval or decline of a transaction, but can help as an indicator for merchants on whether they should proceed with the transaction. Although the street address can sometimes be tricky to match, the postal/zip code is usually a more accurate indicator. AVS is mostly supported by banks throughout Canada, the United States and the United Kingdom. Most card issuers outside of those countries do not participate in the address verification service.
