In a Nutshell

If you’re headed to Costco and planning to use a credit card to pay for your wholesale goods, make sure it’s a Visa because your American Express card won’t be accepted there anymore.

We think it's important for you to understand how we make money. It's pretty simple, actually. The offers for financial products you see on our platform come from companies who pay us. The money we make helps us give you access to free credit scores and reports and helps us create our other great tools and educational materials.

Compensation may factor into how and where products appear on our platform (and in what order). But since we generally make money when you find an offer you like and get, we try to show you offers we think are a good match for you. That's why we provide features like your Approval Odds and savings estimates.

Of course, the offers on our platform don't represent all financial products out there, but our goal is to show you as many great options as we can.

You head off on your errand run and swing by Costco to stock up on paper towels, potato chips and protein bars. You’re calculating how much you’re saving in your head and head to the register. That’s when it hits you.

You don’t have a Visa credit card and don’t have enough cash to pay for the items in your cart. You take out your trusty American Express card to swipe it through the machine only to see that the payment doesn’t go through.


Why doesn’t my American Express card work at Costco?

For a long time, starting in 1999, American Express was Costco’s exclusive credit card partner. It was the only type of credit card accepted at the store, and if members of the wholesale giant wanted a credit card with Costco-related rewards, their only option was to get a co-branded American Express/Costco card.

But that changed when Costco and American Express decided to end their relationship in 2016. After that, Costco went on to name Citi as its exclusive credit card issuer and Visa as its new exclusive credit card network for Costco in the U.S. and Puerto Rico. Since then, American Express has been out and Citi along with Visa has been in — and that has a few implications for Costco members.

Today if you want to use a credit card after shopping at the bulk superstore, there are a few things you should know:

  • You can only use a Visa if you’re paying by credit card at Costco
  • If you want a co-branded credit card with a Costco logo on it, you can now only get it through Citi
  • In addition to Visa cards, Costco still accepts cash, checks, debit and ATM cards, electronic benefit transfer (EBT) and Costco Cash Cards

So, what cards do work at Costco?

If you’re a Costco fan but don’t have a Visa credit card, there’s no need to worry. There are many cards available to meet your needs and still give you the option to continue shopping at Costco.

Here’s one we recommend checking out.

Costco Anywhere Visa® Card by Citi is a co-branded Costco/Citi credit card and a great option for frequent Costco shoppers. It’s a rewards card that gives you cash back at the pump, when eating out, while shopping at Costco, on Costco.com purchases and more.

Here’s a full summary of the cash back rewards you’ll get with this card.

  • 4% cash back on eligible gas around the world and at Costco gas stations (up to $7,000 annually, 1% cash back after that)
  • 3% cash back at restaurants and on eligible travel purchases
  • 2% cash back on all other purchases from Costco and Costco.com
  • 1% cash back on all other purchases

A quick note on cash back rewards: You’ll get an annual reward certificate at the close of the billing cycle each February summing up the amount of cash back you accrued throughout the year. You can then redeem your cash back at any Costco warehouses in the U.S. in the form of cash or merchandise.

The card also doesn’t have an annual fee if you have a paid Costco membership. But you’ll need a Costco membership to shop at the store, and annual memberships range from $60 to $120. Fortunately, once you have a membership, this card can act as your membership ID card.

Is the Costco Anywhere Visa® Card by Citi right for you?

Your lifestyle and interests can play important roles when deciding on a rewards card. Costco Anywhere Visa® Card by Citi might be a great fit if you shop regularly at Costco, enjoy eating out and fill up your gas tank at least weekly.

However, you may find a different Visa that better matches your needs. Here are two other Visa cards you might want to consider:

Chase Sapphire Preferred® Card Good for travel rewards
Chase Freedom Unlimited® Good for balance transfers

Bottom line

Before you head out to Costco, make sure there is a Visa in your wallet if you’re going to use a credit card because your American Express card will no longer work there. The good news is there are many types of Visa cards to choose from if you want to keep using a credit card at Costco.

Whether you decide on going with the Costco Anywhere Visa® Card by Citi or another Visa card depends on your situation and interests. No matter which card you choose, make sure it makes sense for you and gives you what you want from a credit card.
