Costco Gas Accepts Credit Cards, But Only Costco Cards

Costco gas stations take credit cards, but only one kind: a Costco credit card. You cannot pay with Visa, Mastercard, American Express, or Discover at the pump or inside the station, even if those cards are linked to your Costco membership account. The only plastic payment method Costco gas accepts is the Costco Anywhere Visa Card, which is a co-branded card issued by Visa but branded and managed by Costco.

This restriction applies at every Costco gas station in the United States. If you do not have a Costco credit card, you can still buy gas — you just have to pay with a debit card, cash, or a Costco Shop Card (the prepaid card Costco sells). The Costco Anywhere Visa Card is the only credit card option.

Key Takeaways

  • Costco gas stations accept only the Costco Anywhere Visa Card as a credit card; no other credit cards work at the pump.
  • You can pay with a debit card, cash, or a Costco Shop Card (prepaid) if you do not have the Costco credit card.
  • Costco members without the credit card can still buy gas using their membership number and a debit card or cash.
  • The Costco Anywhere Visa Card earns cash back on gas purchases, which is the main financial reason members choose it for fuel.

Why Costco Limits Credit Cards to Its Own Brand

Costco restricts credit card payments to its own card because of the fees Costco pays to Visa, Mastercard, and other networks. When you swipe a Visa or Mastercard, the merchant (Costco) pays a percentage of the sale to the card network and the card issuer — typically 2 to 3 percent on debit cards and higher on credit cards. For a high-volume business like a gas station, those fees add up quickly.

By accepting only the Costco Anywhere Visa Card, Costco negotiates a single fee structure with Visa instead of paying separate fees to multiple networks. This keeps Costco's costs down, which is part of how the company maintains its low gas prices. The trade-off for members is that you need the Costco card to use credit at the pump — but the card itself is free to open and offers cash back on gas, so many members see it as worth the step.

How to Pay With a Costco Credit Card at the Pump

To use your Costco Anywhere Visa Card at a Costco gas station, insert the card into the pump's reader just as you would with any other card. The pump will ask for your ZIP code (the one on your billing address), and then you can select your fuel grade and pump. The transaction processes the same way as any other credit card purchase.

Inside the station, you can also pay at the counter with your Costco card. If you are buying snacks, drinks, or other items along with gas, you can pay for everything together. The card works both at the pump and at the register.

Payment Options If You Do Not Have the Costco Credit Card

If you are a Costco member but do not have the Costco Anywhere Visa Card, you have three other ways to pay for gas. The first is a debit card — any debit card from any bank works at Costco pumps. The second is cash. The third is a Costco Shop Card, which is a prepaid card you load with money at the warehouse and use like a gift card.

All three of these methods work at the pump and at the counter. You will need your Costco membership number to buy gas, but you can look that up on your membership card or in the Costco app if you do not have the card with you. The pump will ask for your ZIP code regardless of which payment method you use.

Cash Back and Rewards on Costco Gas Purchases

The Costco Anywhere Visa Card earns 4 percent cash back on gas purchases at Costco stations. That is the highest rate the card offers — it earns 3 percent on restaurants and travel, 2 percent on other Costco purchases, and 1 percent on everything else. The cash back is paid as an annual reward certificate that you can use at Costco warehouses or online.

If you pay with a debit card, cash, or Costco Shop Card, you earn no rewards on gas. This is the main financial reason many Costco members open the credit card — the 4 percent cash back on gas can offset the cost of the card's annual membership fee over time, depending on how much gas you buy. There is no annual fee on the Costco Anywhere Visa Card itself, only on your Costco membership.

What Happens If You Try to Use Another Credit Card

If you insert a Visa, Mastercard, American Express, or Discover card into a Costco gas pump, the pump will decline the transaction. The screen will display a message saying that card is not accepted. You will need to remove the card and use one of the accepted payment methods instead: the Costco Anywhere Visa Card, a debit card, cash, or a Costco Shop Card.

This happens at the pump itself, so you will know when ready and can switch payment methods without delay. Inside the warehouse, the same rule applies — only the Costco credit card works as a credit card. If you try to pay for warehouse purchases with another credit card, the register will decline it.

Opening a Costco Anywhere Visa Card

You can open a Costco Anywhere Visa Card at any Costco warehouse or online through the Costco website. The process takes a few minutes and asks for your name, address, Social Security number, and income information. Costco will run a credit check, and you will usually find out whether you are approved the same day.

There is no annual fee on the card itself. You do need an active Costco membership to hold the card, and your membership fee is separate. Once you are approved, Costco will mail the physical card to you, which usually arrives within 7 to 10 business days. You can use the card at the pump and in the warehouse as soon as it arrives.

Frequently Asked Questions

Can I use my Costco membership card as a payment method at the pump?

No. Your Costco membership card only proves you are a member and lets you enter the warehouse and buy gas. It does not process payments. You need a separate payment method: the Costco Anywhere Visa Card, a debit card, cash, or a Costco Shop Card.

Do I need a Costco membership to open the Costco Anywhere Visa Card?

Yes. You must have an active Costco membership to hold the card. If your membership expires, you will need to renew it to keep using the card. The card and the membership are separate fees.

Can I use the Costco credit card at other gas stations?

Yes. The Costco Anywhere Visa Card is a Visa card, so it works anywhere Visa is accepted — at other gas stations, grocery stores, restaurants, and online. However, you only earn the 4 percent cash back rate on gas at Costco stations. At other merchants, the card earns lower rates.

What if the pump declines my debit card?

Debit cards sometimes decline at gas pumps if the pump cannot verify your identity or if your bank flags the transaction as suspicious. If this happens, try paying inside at the counter instead, or call your bank to let them know you are buying gas at Costco. You can also use cash or the Costco Shop Card as a backup.

Is the Costco Shop Card the same as the Costco credit card?

No. The Costco Shop Card is a prepaid card you load with cash at the warehouse. The Costco Anywhere Visa Card is a credit card issued by Visa. They are separate products. The Shop Card does not earn rewards, but it does work at the pump if you do not have the credit card.
