Address Verification Service (AVS)

AVS enables merchants that accept card-not-present transactions to compare the billing address (the address to which the card issuer sends its monthly statement for that account) provided by a customer with the billing address on the card issuer's file before processing a transaction. After comparing the provided address with the one they have on file for their cardholder, the card issuer responds by issuing an AVS Response code. Address verification and transaction authorization occur simultaneously and, within seconds, the merchant receives both results.
