Address Verification System

The Address Verification System (AVS ) is a system to verify the identity of a person who owns a credit card. The system checks the address on the credit card with the details of the billing address. Other security options for credit card include the CVV2 number and expiration date.

Example: AVS compares the billing address of the credit card holder. The address is, for example, 101 Main Street, Highland, CA 92346th The AVS 101 checks and 92346th Sometimes AVS checks even more information, such as the apartment number.

From e -commerce online shops (especially in USA) incorrect data is returned if, for example, the German spelling of the street name and house number are specified.

Error message: "The transaction resulted in mismatch of AVS. The address does not match Provided billing address of cardholder. "

For Visa and Mastercard, this service is only available for credit cards that were issued in the United States. American Express offers the Address Verification System for all cards.
