How a billing address is used
The checkout collects the address and the gateway sends it with the authorisation request. Where the issuer supports address verification, the issuer compares what was entered with its own record and returns a result code alongside the approval or decline.
The Visa Core Rules of 18 April 2026 define the Address Verification Service as a service through which a merchant verifies a cardholder's billing address. The result is advice: the merchant decides whether a mismatch is a reason to refuse the order.
The address also feeds the data that 3-D Secure sends to the issuer, fraud scoring, invoices and tax calculation.
Why the billing address matters to a checkout
Every extra field loses some buyers, and issuers in many countries do not check addresses at all. A checkout therefore asks for a full billing address only where it adds something: in markets with address verification, for high-risk orders, or where an invoice needs it.
A billing address is personal data. A gateway stores it with the same care as the rest of the customer record, and keeps it only as long as there is a reason to.
Billing address or shipping address?
- Shipping address
- Where the goods are sent. A difference between the two is a fraud signal, and also an ordinary feature of gifts and office deliveries.
- Card security code
- The digits printed on the card. Like the address, the code shows that the buyer has the card's details, not who the buyer is.
