If you receive an error message related to credit card authorization failure, double-check that the billing address on the credit card matches your account billing address, try re-entering your CVN or security code, and be sure that the card is current (not expired) and valid. After validating the information you've entered and an error message is received on a second attempt, domestic customers email us at customerservice@yaraandco.com or contact your financial institution for further assistance. For international customers, please visit our international help center or contact your financial institution for further assistance.
