AVS Response Codes

Article Summary

The address verification service (AVS) is offered as part of the Visa, Mastercard, Discover and Amex network. The service checks if the address of a credit card is linked to the person claiming to own that card.

The AVS response will not impact the approval or decline of a transaction, but can help as an indicator on whether you 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.
