What the Sam's Club Mastercard is and who issues it

The Sam's Club Mastercard is a co-branded credit card issued by Synchrony Bank in partnership with Sam's Club. Synchrony handles all the account management, billing, and customer service—Sam's Club handles the membership and warehouse operations. When you open the card, Synchrony becomes your card issuer and the company you contact for payment, disputes, or account questions.

The card works at Sam's Club locations and online at samsclub.com, as well as anywhere Mastercard is accepted. You do not need a Sam's Club membership to open the card, but you will need one to shop at the warehouse. The card itself comes with a rewards program that gives you cash back on purchases, with higher rates on Sam's Club spending and fuel.

Synchrony is a major credit card issuer that also runs store cards for other retailers. They manage the underwriting (the decision to approve or deny you), set the credit limit, and handle all ongoing account administration. Sam's Club sets the rewards rates and membership benefits that come with the card.

Key Takeaways

  • The card earns cash back at Sam's Club and gas stations at higher rates than other purchases, with exact percentages varying by membership tier.

  • Synchrony will pull your credit report and review your credit history before deciding whether to approve your process.

How to open a Sam's Club Mastercard account

You can start the process on samsclub.com or in a Sam's Club warehouse. The online route is faster—you go to the Sam's Club website, find the credit card section, and click the link to explore. You will need your Social Security number, date of birth, address, and income information. Synchrony will ask for your employment status and annual income, though they do not verify this information against tax returns or W-2s at the time of process.

The process takes about 10 minutes. Synchrony will pull your credit report from one or more of the three major credit bureaus (Equifax, Experian, or TransUnion). This pull is a hard inquiry, which shows up on your credit report and can lower your score by a few points for several months. After you submit, you will get a decision within minutes in most cases—either approved, denied, or pending review.

If you are approved, Synchrony will mail your physical card to the address you provided. The card typically arrives within 7 to 10 business days. You can also explore in person at a Sam's Club warehouse, where a staff member can walk you through the process on a tablet or computer. In-warehouse applications follow the same timeline and credit check.

Activating your card and setting up online access

When your card arrives, you will see a sticker on the front with instructions to call a phone number or visit a website to set up it. You can set up by phone (the number is on the sticker) or online through Synchrony's website. set up takes a few minutes and requires you to verify your identity—usually by confirming your last four Social Security digits and your date of birth.

After set up, you can set up online account access at Synchrony's website. You will create a username and password, and Synchrony will send you a temporary access code via email or text to confirm your identity. Once you log in, you can view your balance, make payments, set up automatic payments, and read statements. You can also read the Synchrony mobile app to manage your account from your phone.

Your card is ready to use when ready after set up. You can use it at any Sam's Club location, at samsclub.com, at gas stations, or anywhere Mastercard is accepted. If you do not set up within 30 days of receiving it, Synchrony may close the account, so set up as soon as the card arrives.

Understanding the rewards structure and cash back rates

The Sam's Club Mastercard earns cash back on all purchases, but the rate depends on where you shop and what membership tier you have. At Sam's Club warehouses and samsclub.com, you earn a higher rate—this varies by membership level, typically ranging from 2% to 5% cash back. At gas stations (including Sam's Club fuel stations), you earn a set rate, usually 5% cash back. On all other purchases, you earn a lower rate, typically 1% cash back.

The exact rates change based on your membership type—Sam's Club Plus members earn higher cash back percentages than standard members. You can see your specific rates in your Synchrony account or on the Sam's Club website. Cash back is not automatic—you must redeem it. Most cardholders redeem as a statement credit (which reduces their balance) or as a Sam's Club purchase credit that appears in their account.

There is no annual fee for the Sam's Club Mastercard, and there is no minimum spending requirement to earn rewards. Cash back does not expire as long as your account remains open and in good standing. If you close the account, any unredeemed cash back may be forfeited, so check your balance before closing.

How to make payments and manage your account

You can pay your Sam's Club Mastercard bill online through Synchrony's website or mobile app, by phone, by mail, or in person at a Sam's Club warehouse. Online and mobile payments are free and typically post within one business day. Phone payments are also free—the number is on your statement or in your online account. Mail payments take 7 to 10 business days to arrive and post, so send them early if your due date is approaching.

Your statement is due on the same date each month, shown on your bill. If you pay the full balance by the due date, you will not be charged interest. If you carry a balance, Synchrony will charge interest at the Annual Percentage Rate (APR) shown in your account—this rate varies based on your creditworthiness and current market conditions. You can set up automatic payments so the full balance, a fixed amount, or the minimum payment is deducted from your bank account each month.

You can view your balance, recent transactions, and available credit anytime in your online account or app. If you notice a transaction you did not make, you can report it as fraud or dispute it through your Synchrony account. Synchrony has a 60-day window to investigate disputes, and you are not responsible for fraudulent charges while the investigation is underway.

What happens if you miss a payment or carry a balance

If your payment is not received by the due date, Synchrony will report it as late to the credit bureaus. A payment that is 30 days late will show on your credit report and may lower your credit score. Synchrony may also charge a late fee, which appears on your next statement. If your payment is 60 days late, Synchrony may increase your APR as a penalty. If your account reaches 180 days past due, Synchrony may close the account and send it to a collection agency.

If you are carrying a balance and cannot pay it in full, you can still make the minimum payment to avoid late fees and credit damage. The minimum payment is shown on your statement and is usually 1% to 3% of your balance plus any fees and interest. Paying only the minimum means you will pay interest on the remaining balance, and it will take much longer to pay off the card.

If you are struggling to make payments, contact Synchrony before you miss a due date. Synchrony has hardship programs that may lower your interest rate or allow you to pause payments temporarily. You can reach Synchrony's customer service through your online account, by phone (the number is on your statement), or by mail.

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

The Sam's Club Mastercard competes with cards like the Costco Anywhere Visa, the Amazon Prime Rewards Visa, and general cash back cards from other issuers. The main difference is the rewards rate and where you shop. If you spend most of your money at Sam's Club, the Sam's Club Mastercard will earn you more cash back than a general card. If you shop at multiple warehouses or spend heavily on groceries outside Sam's Club, a different card might earn more.

The Costco Anywhere Visa is issued by Visa (not Mastercard) and earns higher cash back at Costco, but you must be a Costco member to use it. The Amazon Prime Rewards Visa earns cash back at Amazon and Whole Foods, which is useful if you shop there regularly. A general 2% cash back card from another issuer might earn more if you do not spend much at Sam's Club specifically.

The best card for you depends on where you shop and how much you spend. If you are a regular Sam's Club shopper, the Sam's Club Mastercard will likely earn you more rewards than a general card. If you shop at multiple retailers, you may want to compare the cash back rates and annual fees across all your options before opening a new card.

Frequently Asked Questions

Do I need a Sam's Club membership to open the card?

No, you can open the Sam's Club Mastercard without a membership. However, you will need a membership to shop at Sam's Club warehouses and use the higher cash back rates. You can purchase a membership at the same time you open the card, either online or in person at a warehouse.

What is Synchrony's customer service phone number?

The phone number is on the back of your card and on your monthly statement. You can also find it by logging into your Synchrony account online. Synchrony's customer service is available 24/7 for most account questions, fraud reports, and payment issues.

Can I use the Sam's Club Mastercard outside the United States?

Yes, you can use it anywhere Mastercard is accepted internationally. However, Synchrony will charge a foreign transaction fee, usually 3% of the purchase amount. Check your account terms or call Synchrony before traveling to confirm the exact fee.

What credit score do I need to open the card?

Synchrony does not publish a minimum credit score requirement. Generally, applicants with fair to good credit (a score of 650 or higher) have a reasonable chance of approval, but Synchrony also considers your income, employment history, and existing debts. If you are denied, you can ask Synchrony why and reapply after improving your credit.

How do I redeem my cash back rewards?

Log into your Synchrony account and look for the rewards or cash back section. You can usually redeem as a statement credit (which reduces your balance) or as a Sam's Club purchase credit. Some accounts also allow you to redeem as a check mailed to your address. The exact options depend on your account type.
