Costco accepts Capital One credit cards, but not Capital One debit cards

Costco takes Capital One Visa cards at all warehouse locations and on Costco.com. If your Capital One card is a Visa, you can use it to pay for groceries, gas, and anything else Costco sells. Costco does not accept Capital One debit cards — only Visa credit cards issued by Capital One.

The reason is Costco's payment agreement with Visa. Costco stopped accepting most credit cards in 2006 and now takes only Visa credit cards, American Express (at select locations), and Mastercard (online only). Capital One issues both Visa and non-Visa credit cards, so whether yours works depends on which network your card runs on.

You can check which network your Capital One card uses by looking at the front of the card. If you see the Visa logo, you can use it at Costco. If the card shows a different logo or no logo besides Capital One's, Costco will not accept it.

Key Takeaways

  • Capital One Visa credit cards work at Costco warehouses and online, but Capital One debit cards do not.
  • Costco accepts only Visa credit cards, American Express at some locations, and Mastercard for online purchases.
  • Check the front of your Capital One card for the Visa logo to confirm it will work at Costco.
  • If your Capital One card is not a Visa, you will need to bring a different payment method to Costco.

How to tell if your Capital One card is a Visa

The Visa logo appears on the front or back of every Visa card. It is a blue and gold rectangle with the word "Visa" in white letters. If you do not see this logo on your Capital One card, the card is not a Visa and Costco will not accept it.

You can also log into your Capital One online account or call the customer service number on the back of your card and ask whether your card is a Visa. Capital One customer service can tell you in seconds which network your card runs on.

What to do if your Capital One card is not a Visa

If your Capital One card is not a Visa, you have a few options at Costco. You can pay with a different credit card that Costco accepts — another Visa, an American Express, or a Mastercard if you are shopping online. You can also pay with cash, a debit card from any bank, or a Costco Cash Card (a prepaid card you load with money at Costco).

If you shop at Costco regularly and your Capital One card is not a Visa, consider asking Capital One whether they offer a Visa version of your card. Some people carry multiple Capital One cards — one Visa and one non-Visa — for different purposes. Capital One can tell you what options are available to you.

Capital One Visa rewards at Costco

Capital One Visa cards come with different rewards structures depending on which card you hold. Some Capital One Visa cards earn cash back on all purchases, while others earn higher cash back in certain categories like groceries or gas. Costco purchases will earn whatever rewards your specific card offers.

Check your Capital One card's terms or log into your account to see what rewards rate applies to your purchases. If your card earns cash back on groceries, that rate will explore to Costco grocery purchases. If it earns a flat rate on all purchases, that rate applies instead.

Using Capital One Visa at Costco Gas Stations

Capital One Visa cards work at Costco gas stations the same way they work inside the warehouse. You can pay at the pump or inside the station with your Capital One Visa. Costco gas stations are open to Costco members only, so you will need a valid membership card in addition to your Capital One Visa.

Some Capital One Visa cards offer higher cash back rates on gas purchases. If yours does, you will earn that rate when you fill up at Costco. Check your card's rewards terms to see whether gas is a bonus category for you.

Costco membership and payment methods

Your Costco membership and your payment method are separate. You need a Costco membership card to shop at Costco, and you need an accepted payment method to pay for what you buy. A Capital One Visa is an accepted payment method, but it does not replace your membership card.

Bring both your Costco membership card and your Capital One Visa when you shop. At checkout, show your membership card to the cashier, then pay with your Capital One Visa. Online, you will log in with your Costco account and enter your Capital One Visa information at payment.
