The Sam's Club Mastercard is issued by Synchrony and works like a standard store credit card

The Sam's Club Mastercard is a store credit card issued by Synchrony Bank, the financial company that handles credit for many retailers. You use it to make purchases at Sam's Club locations and on their website, and you pay the balance back to Synchrony each month. Unlike a general-purpose credit card, this card is designed specifically for Sam's Club members and offers rewards on Sam's Club purchases.

Synchrony handles all the behind-the-scenes work: they approve your process, set your credit limit, send your monthly statement, and process your payments. When you call customer service about your Sam's Club card, you are calling Synchrony, not Sam's Club itself. This matters because Synchrony's policies on interest rates, late fees, and payment options are what govern how the card actually works in your wallet.

Key Takeaways

  • The Sam's Club Mastercard earns rewards on purchases at Sam's Club and on gas, but the rewards rate and redemption method depend on which version of the card you hold.
  • You need an active Sam's Club membership to open the card, and you must maintain that membership to keep the card active.
  • Synchrony sets the interest rate based on your credit history, and that rate can change over time; the card has no annual fee.
  • You can pay your bill online through Synchrony's website, by phone, by mail, or through automatic payments, and payments are due by the date shown on your statement.
  • If you close your Sam's Club membership, Synchrony will close your credit card account as well.

What rewards you earn and how to use them

The Sam's Club Mastercard comes in two versions: the standard card and the Sam's Club Business Mastercard. Both earn rewards on purchases, but the rates differ. The standard card earns rewards on Sam's Club purchases and on gas bought outside Sam's Club, though the exact rate varies depending on which tier of Sam's Club membership you hold (Gold Star or Platinum). The business version has its own reward structure for business purchases.

Rewards are not automatically redeemed. Instead, they accumulate as a Sam's Club Cash reward that appears in your Sam's Club account. You can view your reward balance online or in the Sam's Club mobile app, and the reward is applied as a credit when you check out at a Sam's Club register or on their website. You do not need to do anything to "cash out" — the system applies it automatically at checkout if you have a balance.

Rewards do not expire as long as your membership and card account remain active. However, if you close your membership or your card account is closed, any unused rewards may be forfeited. Check your Sam's Club account regularly to see your current reward balance and use it before any account changes occur.

How to open a Sam's Club Mastercard account

To open the card, you must already be a Sam's Club member. If you are not yet a member, you will need to join Sam's Club first — membership requires an in-person visit to a Sam's Club location or an online signup. Once you have an active membership, you can explore for the credit card online through Sam's Club's website, in a Sam's Club warehouse, or by phone.

The process asks for your name, address, Social Security number, income, and employment information. Synchrony will pull your credit report to make a decision, which may lower your credit score slightly. You will receive a decision within minutes to a few days. If approved, your card will arrive by mail within 7 to 10 business days, and you can begin using it when ready once it arrives.

If you are denied, you can contact Synchrony to understand why. Common reasons include insufficient credit history, a recent bankruptcy, or too many recent credit inquiries. You may reapply after addressing the issue, though explore again when ready will likely result in another denial.

Interest rates, fees, and how payments work

The Sam's Club Mastercard has no annual fee. The interest rate (called the Annual Percentage Rate, or APR) is set by Synchrony based on your credit score and credit history at the time you explore. This rate is not fixed — Synchrony can raise or lower it over time, though they must notify you in writing before making a change. The APR applies to any balance you carry from month to month; if you pay your full statement balance by the due date, no interest is charged.

Late fees explore if your payment arrives after the due date shown on your statement. Synchrony also charges a fee if your payment bounces due to insufficient funds. These fees are separate from interest and are added to your balance. If you miss a payment by 30 days or more, the late payment will be reported to credit bureaus and may lower your credit score.

You can pay your bill through several methods: online at Synchrony's website using your bank account, by phone by calling the number on your statement, by mail by sending a check to the address listed on your bill, or by setting up automatic payments so the amount is withdrawn from your bank account each month. Automatic payments are the easiest way to avoid missing a due date.

What happens if you close your Sam's Club membership

Your Sam's Club Mastercard is tied to your membership. If you let your membership expire or cancel it, Synchrony will automatically close your credit card account. This closure will be reported to credit bureaus and may lower your credit score, even if you have never missed a payment. The card will no longer work for purchases.

If you have a balance on the card when your membership closes, you will still owe that balance to Synchrony. You can continue making payments by phone, mail, or online, but you cannot use the card to make new purchases. Any unused rewards will be forfeited when the account closes.

If you plan to rejoin Sam's Club later, you can reapply for the credit card at that time. Synchrony will review your process as if you were a new customer, and approval is not may provide even if you held the card before.

How to manage your account online and by phone

Synchrony offers an online portal where you can view your statement, make payments, set up automatic payments, and update your contact information. You can access this portal through Synchrony's website or through the Sam's Club mobile app if you link your credit card account. The portal shows your current balance, available credit, recent transactions, and reward balance.

If you prefer to handle things by phone, you can call the customer service number on the back of your card. Synchrony's representatives can answer questions about your balance, process payments over the phone, help you set up automatic payments, and address billing disputes. Phone lines are open during business hours, typically 7 a.m. to 11 p.m. Eastern time, seven days a week.

If you notice a transaction you did not make, you can report it as fraudulent through the online portal or by calling customer service. Synchrony will investigate and may issue a temporary credit while the investigation is underway. Unauthorized transactions are typically covered under Synchrony's fraud protection policy, though you may be asked to provide documentation.

Comparing the Sam's Club card to other warehouse and grocery store cards

The Sam's Club Mastercard is one option if you shop at Sam's Club regularly, but other warehouse and grocery retailers offer their own credit cards or rewards programs. Costco does not issue a credit card but offers cash back through their Costco Anywhere Visa card issued by Citi. Walmart offers a store card through Synchrony as well. The choice depends on where you shop most often and which rewards structure benefits you most.

If you shop at multiple retailers, a general-purpose rewards credit card from a bank might earn rewards at all of them rather than just one store. However, store cards often offer higher rewards rates on purchases at that specific retailer, which can offset the narrower use. Calculate your typical monthly spending at Sam's Club to see whether the rewards rate justifies carrying another card.

Frequently Asked Questions

Can I use the Sam's Club Mastercard outside of Sam's Club?

Yes, the card is a Mastercard and works anywhere Mastercard is accepted. However, you only earn rewards on purchases at Sam's Club and on gas bought outside Sam's Club. Regular purchases at other retailers earn no rewards, so the card is most valuable if you use it primarily at Sam's Club.

What is the credit limit on the Sam's Club Mastercard?

Synchrony sets your credit limit based on your credit score, income, and credit history. There is no standard limit; it varies by person. You can request a credit limit increase by contacting Synchrony after you have held the card for several months and made on-time payments.

Do I lose my rewards if I pay off my balance in full each month?

No. Rewards are earned on purchases regardless of whether you carry a balance or pay in full. Paying in full each month is actually the best approach because you avoid interest charges while still earning rewards.

What happens to my card if my Sam's Club membership expires?

Synchrony will close your credit card account automatically when your membership expires. Any remaining balance must still be paid, but you cannot make new purchases with the card. Rejoin Sam's Club and reapply for the card if you want to use it again.

Can I transfer my Sam's Club Mastercard balance to another credit card?

Yes, you can perform a balance transfer to another card issued by a different bank. Contact the other card issuer to initiate the transfer. Be aware that balance transfers typically have a fee and may have a different interest rate than regular purchases.
