Foreign visitors to Walmart locations in the United States can use their credit cards issued by banks outside of the U.S. Walmart accepts international credit cards, including American Express, Discover, MasterCard and Visa. Some Walmart stores may accept international credit cards issued by JCB and UnionPay (only those with the "UnionPay" logo on the front of the card and card numbers starting with "62") as well.
Tips for Using Your International Credit Card at Walmart Stores
To be sure what credit cards are accepted at the Walmart store that you're visiting, consult the "We gladly accept" sign located at the store's entrance.
The international financial institution that issued your credit card may require advance notification that you're traveling to authorize transactions abroad. Call the customer service line on the back of your card and notify the representative about your travel plans to prevent any problems.
The chip-and-pin cards are very new in the U.S. Their current iteration, as of October 2015, is closer to "chip-and-sign" cards. Some Walmart pay terminals may ask you to provide a signature instead of your card's PIN.
If you run into any issues when processing your card's chip, payment terminals at Walmart are still equipped with magnetic stripe readers. If you card has a magnetic stripe, you can use it as a backup plan for payment.
Tips for Using Your International Credit Card on Walmart's Website
When using your international credit card to shop on Walmart.com, remember that Walmart's site only delivers orders to the 50 states, APO/FPO military addresses and U.S. territories.
Most credit and debit cards issued by banks outside of the U.S. are accepted forms of payment for purchases made on Walmart.com. To ensure that your transaction goes through, Walmart recommends that you enter your full billing international address in the Billing Address line and your international phone number without the 001 or 011 prefix in the Billing Phone Number line. If your transaction is declined, your order is canceled and you'll receive a notification to the email addressed that you used to attempt your purchase.
