Where You Can Use Your Sam's Club Credit Card

You can use your Sam's Club credit card at Sam's Club warehouses, on their website, and at gas stations inside Sam's Club locations — but not at other retailers

The Sam's Club Mastercard works only within the Sam's Club ecosystem. That means you can swipe it at any of the roughly 600 Sam's Club warehouse locations in the United States, on Samsclub.com when you order online, and at the fuel stations that sit at the entrance of most warehouses. You cannot use it at grocery stores, restaurants, or other businesses the way you would a standard Mastercard.

This is different from a regular credit card. The Sam's Club card is designed as a membership benefit, not a general-purpose payment tool. If you need a card that works everywhere, you would need a different card — either a standard Mastercard or Visa from another bank, or a different rewards card that accepts merchants outside a single chain.

Key Takeaways

• The Sam's Club Mastercard works only at Sam's Club warehouses, Samsclub.com, and Sam's Club fuel stations.
• You must have an active Sam's Club membership to use the card, and the card itself is tied to your membership account.
• The card earns rewards points on purchases at Sam's Club, but those points do not transfer to other retailers.
• If you need a card that works at other stores, you will need a separate credit card from a different bank or card network.

How the card works at Sam's Club warehouses

When you shop in person at a Sam's Club location, you present your membership card at the entrance, then use your Sam's Club Mastercard to pay for your purchases at checkout. The card pulls from your credit line, not your membership balance. Your rewards points post to your account after the transaction clears, usually within a few days.

You do not need to do anything special to activate the card for warehouse use — it works as soon as you receive it in the mail, provided your membership is active. If your membership lapses, the card will still function as a Mastercard at other merchants that accept Mastercard, but you lose access to the warehouse and the rewards program.

Online shopping on Samsclub.com

You can use your Sam's Club Mastercard to pay for orders on Samsclub.com. Enter your card number, expiration date, and CVV at checkout just as you would on any other website. The same rewards structure applies — you earn points on your purchase, and those points show up in your Sam's Club account.

Online orders ship to your home or to a Sam's Club location for pickup, depending on the item and your preference. Delivery times vary by location and product type. Your card statement will show the charge as a Sam's Club purchase, and the transaction counts toward any annual spending thresholds if your membership tier has them.

Fuel purchases at Sam's Club gas stations

Most Sam's Club warehouses have a fuel station at the entrance where members can buy gasoline and diesel. You can pay with your Sam's Club Mastercard at the pump or inside the fuel station kiosk. These purchases earn rewards points at the same rate as in-warehouse purchases, though the exact rate depends on your membership tier and the current rewards structure.

You do not need to be shopping inside the warehouse to use the fuel station — you can drive in, fill up, and leave. However, you still need an active Sam's Club membership to access the pumps. If your membership has expired, the pump will not activate your card.

What happens if you try to use it outside Sam's Club

If you attempt to use your Sam's Club Mastercard at a retailer outside the Sam's Club system — a grocery store, restaurant, or gas station that is not part of Sam's Club — the transaction will be declined. The card is restricted to Sam's Club merchants only, and the payment network blocks any other use.

This restriction exists because the card is a membership benefit, not a general credit card. Sam's Club controls where the card can be used to keep the rewards program tied to their business. If you need a card that works everywhere, you would need to carry a separate Mastercard or Visa from another bank.

International use and travel

The Sam's Club Mastercard cannot be used at Sam's Club locations outside the United States. There are no Sam's Club warehouses in other countries, so the card has no international merchant network to tap into. If you travel abroad and need to make purchases, you would need a different credit card.

Even though the card carries the Mastercard logo, the Sam's Club restriction overrides the standard Mastercard network. You cannot use it as a regular Mastercard overseas. Before traveling, confirm that you have a separate card that works internationally, or contact Sam's Club to discuss travel options.

How rewards points work with your card

Every purchase you make with your Sam's Club Mastercard earns rewards points. The number of points per dollar spent varies depending on your membership level — Gold Star members earn at one rate, and Plus members earn at a higher rate. Points accumulate in your Sam's Club account and can be redeemed for discounts on future purchases or merchandise.

Points do not expire as long as your membership remains active. If your membership lapses, you lose access to your points balance. Points earned through the card stay within the Sam's Club ecosystem — you cannot transfer them to airline miles, hotel programs, or other loyalty schemes.

Frequently Asked Questions

Can I use my Sam's Club card if my membership expires?

No. Once your membership lapses, the card stops working at Sam's Club warehouses and fuel stations. The card will function as a regular Mastercard at other retailers that accept Mastercard, but you lose warehouse access and rewards benefits. You must renew your membership to use the card at Sam's Club again.

What if I lose my Sam's Club card?

Contact Sam's Club customer service to report the card lost or stolen. They will cancel the card and issue a replacement, which typically arrives within 7 to 10 business days. In the meantime, you can still shop at Sam's Club using your membership number and a different payment method.

Do I earn rewards on fuel purchases?

Yes. Fuel purchases at Sam's Club gas stations earn rewards points at the same rate as warehouse purchases. The exact rate depends on your membership tier. Points post to your account after the transaction clears, just like in-warehouse purchases.

Can I use the card at other Mastercard merchants?

No. The Sam's Club Mastercard is restricted to Sam's Club locations only. It will not work at other retailers, even though it carries the Mastercard logo. If you need a card for general use, you need a separate credit card from another bank.

What should I do if my card is declined at Sam's Club?

First, check that your membership is active and has not expired. If your membership is current, the decline may be due to fraud detection or a technical issue. Contact Sam's Club customer service or your card issuer to troubleshoot. You can also pay with a different method while the issue is resolved.
