Yes, Costco accepts credit cards—but with an important catch. Not all credit cards are welcome, and the ones that are depend on your membership tier and where you shop. Understanding Costco's payment landscape helps you know what plastic will work at checkout and what won't.
Costco's main credit card partnership is with Visa. This means Visa-branded credit cards—whether from your bank, a retailer, or Costco itself—are accepted at most Costco warehouse locations in the United States.
For decades, American Express held the exclusive relationship with Costco, but that partnership ended in 2016. The shift to Visa opened the door to a much wider range of cards, though it also means other major networks face restrictions.
| Card Network | Status at Costco Warehouses | Notes |
|---|---|---|
| Visa | ✓ Accepted | Primary accepted network; includes Costco Anywhere Visa |
| Mastercard | ✗ Not accepted | Costco does not accept Mastercard at warehouse locations |
| American Express | ✗ Not accepted | Partnership ended in 2016 |
| Discover | ✗ Not accepted | Discover cards are not accepted |
| Costco Anywhere Visa | ✓ Accepted & rewards | Costco's co-branded card; earns cash back on purchases |
This creates a real limitation: if your primary credit card is a Mastercard, Amex, or Discover card, you cannot pay with it at a Costco warehouse. You'd need to use a different Visa, debit card, or another payment method.
Costco.com (their e-commerce site) accepts a broader range of credit cards, including Mastercard and American Express, along with Visa. So your payment options expand if you're ordering online rather than shopping in the warehouse.
This distinction matters if you rely on a non-Visa card and want the flexibility to shop either way.
Credit card limitations don't mean you're stuck. Costco warehouses also accept:
So even without a qualifying credit card, you have multiple ways to complete a purchase.
Costco offers its own co-branded Costco Anywhere Visa Card, which is accepted everywhere Visa is accepted (not just Costco) and earns cash back on Costco purchases. Some members find this card valuable if they shop at Costco regularly and want rewards that compound over time.
Whether a co-branded card makes sense depends on your spending patterns, existing card benefits, and interest in simplified rewards tracking—not something we can evaluate for you.
If you carry a Mastercard or American Express as your primary card:
None of these is universally "best"—the right choice depends on convenience, your spending habits, and whether you value cashback or rewards.
Costco's credit card acceptance is straightforward once you know the rule: Visa cards are in; everything else is out at warehouse locations. Online shopping is more flexible. If your go-to credit card doesn't fit, you have alternatives, but knowing this ahead of time saves frustration at checkout. 💳
