Receiving the message "Error: Verify AVS Failed" when adding your credit or debit card indicates a mismatch in the information with the Address Verification Service (AVS). This service is responsible for confirming the cardholder's billing address.
To address this problem, double-check that the information you provided is correct. The billing address must correspond with the one associated with your credit card. If everything appears correct but the error persists, contact your financial institution for assistance.
