Where You Can Use Your Costco Credit Card and Where You Can't

The Costco Credit Card Works at Costco Warehouses and Online, But Nowhere Else

The Costco Anywhere Visa Card by American Express is designed specifically for Costco members and works only at Costco locations and Costco.com. You cannot use it at other retailers, restaurants, gas stations, or anywhere outside the Costco ecosystem. If you try to swipe it at a grocery store or department store, it will be declined.

This is different from a regular credit card. Most credit cards work anywhere that accepts Visa, Mastercard, or American Express. The Costco card is restricted by design — Costco limits where you can use it to keep the card tied to membership and to control how the rewards program works.

If you need a card that works everywhere, you would need a different credit card in addition to the Costco card. Many people carry both: the Costco card for warehouse purchases and a general-purpose card for other spending.

Key Takeaways

• The Costco Anywhere Visa Card works only at Costco warehouses, Costco.com, and the Costco Gas stations inside warehouses.
• You cannot use this card at other stores, restaurants, online retailers, or anywhere outside Costco locations.
• The card is tied to your Costco membership, so you must be a member to hold it and use it.
• If you need a credit card that works everywhere, you should carry a second card alongside the Costco card.

Where the Costco Card Is Accepted

The Costco Anywhere Visa Card works at all Costco warehouse locations in the United States, Canada, Mexico, Japan, South Korea, Taiwan, and the United Kingdom. You can use it in person at the register or at the self-checkout kiosks.

Online, the card works on Costco.com for purchases shipped to your home. You can also use it at Costco Gas stations, which are located inside or adjacent to warehouse buildings. The card will not work at standalone gas stations or at Costco Travel, which requires a different payment method.

If you are traveling internationally to a country where Costco operates, you can use the card at those warehouses. However, if you travel to a country without Costco locations, the card will not work anywhere.

Why Costco Restricts Where You Can Use This Card

Costco restricts the card to its own locations because the rewards program is built around Costco purchases. The card earns cash back on Costco spending — typically 2% at the warehouse and 1% on other purchases. By limiting where you can use it, Costco ensures the card is used for what it was designed for.

The restriction also protects Costco's business model. Costco makes money from membership fees and from the products it sells. A card that only works at Costco keeps members coming back to the warehouse instead of shopping elsewhere. It strengthens the relationship between the member and the company.

From a practical standpoint, the restriction simplifies fraud prevention. Costco can monitor card use more easily when it knows exactly where the card should be used. Unusual activity outside Costco locations is immediately flagged as suspicious.

What Happens If You Try to Use It Elsewhere

If you attempt to use the Costco Anywhere Visa Card at a retailer that is not Costco, the transaction will be declined at the point of sale. The card reader will reject it, and you will need to provide a different payment method to complete your purchase.

The decline is not a mistake or a temporary block. It is how the card is programmed. You will not receive an error message explaining why — the card simply will not work. If you are unsure whether a location accepts the card, you can call the number on the back of your card or contact Costco member services before attempting the purchase.

Some people mistakenly believe the card will work at gas stations or pharmacies outside Costco. It will not. The only gas stations where it works are Costco Gas locations inside warehouses.

Using a Different Card When the Costco Card Does Not Work

Since the Costco card only works at Costco, you will need a second credit card for everyday purchases outside the warehouse. Many people carry a general-purpose Visa or Mastercard for groceries, restaurants, online shopping, and other retailers.

You might choose a card based on what rewards it offers. Some cards earn cash back on groceries or dining. Others offer points you can redeem for travel. The key is to pick a card that works where you actually shop, since the Costco card covers only Costco spending.

If you do not have a second card, you can use a debit card, prepaid card, or cash at other retailers. The Costco card is not your only payment option — it is one tool for one specific place.

How to Check If a Location Accepts the Costco Card

The simplest way to know if a location accepts the Costco card is to remember the rule: Costco warehouses, Costco.com, and Costco Gas stations only. If you are not at one of those three places, the card will not work.

If you are unsure whether a specific Costco location accepts the card, you can call that warehouse directly or visit Costco.com to confirm. You can also call the customer service number on the back of your card. Costco member services can tell you whether a particular location or service accepts the card.

When shopping online, Costco.com will accept the card at checkout. If you are using a third-party seller through Costco's marketplace, check the payment options listed before you place your order, as some third-party sellers may have different payment rules.

International Use of the Costco Card

If you travel to a country where Costco operates, you can use the card at that country's Costco warehouses. The card works in Canada, Mexico, Japan, South Korea, Taiwan, and the United Kingdom. You will need to be a Costco member in that country or have a valid membership card to enter the warehouse.

Outside Costco warehouses in those countries, the card will not work. You will need a different payment method for restaurants, hotels, shops, and other businesses. If you are traveling to a country without Costco locations, bring a general-purpose credit card or notify your bank that you will be traveling so your other cards are not blocked.

Currency conversion fees may apply when you use the card internationally at Costco warehouses. Check with American Express or your Costco card documentation for current foreign transaction fees.

Frequently Asked Questions

Can I use my Costco card at Sam's Club or other warehouse clubs?

No. The Costco card works only at Costco locations. Sam's Club, BJ's Wholesale, and other warehouse clubs have their own membership cards and do not accept the Costco Anywhere Visa Card. You would need a separate membership and card for those retailers.

Will the card work at Costco Travel?

No. Costco Travel requires a different payment method. You can use a general-purpose credit card, debit card, or other payment method to book travel through Costco Travel, but the Costco Anywhere Visa Card is not accepted there.

What if I lose my Costco card while traveling?

Call the number on the back of your card or contact American Express immediately to report it lost or stolen. American Express will cancel the card and can issue a replacement. If you are traveling and need to make a purchase at Costco, you can show your Costco membership card at the warehouse and use a different payment method to complete the transaction.

Can I use the Costco card for online purchases outside Costco.com?

No. The card is restricted to Costco.com only for online purchases. You cannot use it on Amazon, eBay, other retailers' websites, or any online store outside the Costco ecosystem. You will need a different credit card for those purchases.

Does the card work at Costco pharmacies or optical centers?

Yes, if those services are located inside a Costco warehouse. The card works anywhere inside the warehouse building. However, if a Costco pharmacy or optical center operates as a standalone location outside the warehouse, the card will not work there.
