If Your Card Is Issued by a Non-U.S. Bank
Credit and debit cards issued by banks outside of the U.S. are a valid form of payment on Walmart.com. These cards are subject to the same security checks as cards issued by banks in the U.S.
The security checks are intended to ensure the safety and security of your financial information and prevent unauthorized use of your credit or debit card. Unfortunately, communication with foreign banks is not always as seamless as with banks based in the U.S., and we may be unable to verify the information required to complete your transaction.
If we are unable to verify payment, we will cancel your order and send you notification by email that the order could not be completed. To further ensure security and privacy, these emails do not include details of why the order was not completed.
