What Credit Cards Does Costco Accept? A Complete Guide to Costco's Payment Policy

If you've ever pulled out the wrong card at a Costco checkout — or done the math on which card to carry before a big warehouse run — you already know this matters. Costco has one of the most specific payment policies of any major retailer, and understanding exactly how it works can affect both your shopping experience and your rewards strategy.

Costco Only Accepts Visa Credit Cards

This is the core fact: Costco warehouse locations in the United States exclusively accept Visa-branded credit cards. Mastercard, American Express, and Discover credit cards are not accepted at the register inside U.S. Costco warehouses.

This policy is a direct result of Costco's exclusive co-branded partnership with Citibank, which issues the Costco Anywhere Visa Card. That partnership — secured when Costco ended its long-running relationship with American Express in 2016 — locked in Visa as the only accepted credit network in-store.

This surprises a lot of shoppers, especially those who carry premium Amex or Mastercard rewards cards. It's worth knowing before you show up with a cart full of bulk paper towels and a card Costco won't take.

What About Debit Cards, Cash, and Checks?

Costco accepts a broader range of payment methods beyond credit cards:

The key distinction: debit cards follow different rules than credit cards. Costco accepts debit cards from multiple networks, including Mastercard debit. The Visa-only restriction applies specifically to credit cards.

Costco.com Accepts More Card Types

The in-warehouse restriction does not apply online. Costco.com accepts Visa, Mastercard, and Discover credit cards for purchases. American Express is still not accepted on Costco's website, but the broader online acceptance gives cardholders more flexibility when ordering for delivery or pickup.

This distinction matters for shoppers who earn strong rewards on a non-Visa card. Routing certain purchases through Costco.com can let you use cards that wouldn't work at the physical register.

The Costco Anywhere Visa Card: How It Fits In

Because Visa is the only accepted credit network in Costco warehouses, many members consider the Costco Anywhere Visa Card by Citi — the store's own co-branded card. It's structured as a rewards credit card rather than a traditional closed-loop store card, meaning it can be used anywhere Visa is accepted, not just at Costco.

The card earns tiered cash-back rewards across spending categories — including at Costco itself, on gas, dining, and travel — and redemption happens once per year in the form of a reward certificate, usable in-store or redeemable for cash.

Whether this card makes sense depends entirely on your spending patterns and existing credit profile. It requires a Costco membership to apply and is generally targeted at applicants with good to excellent credit, though specific approval criteria are set by Citi and aren't publicly disclosed.

What Issuers Typically Evaluate for a Card Like This 🔍

Co-branded rewards cards — including store-affiliated Visa cards — typically involve standard credit underwriting. Factors that influence approval decisions include:

• Credit score range — higher scores generally improve approval odds, though the exact thresholds vary by issuer
• Credit utilization — how much of your available revolving credit you're currently using
• Payment history — whether you've paid past accounts on time
• Length of credit history — how long your accounts have been open
• Recent hard inquiries — applying for multiple cards in a short window can signal risk
• Income and debt-to-income ratio — issuers want to see you can manage additional credit

These factors don't operate in isolation. A long, clean payment history can offset a moderately high utilization rate. A high income can counterbalance a shorter credit history. Issuers weigh the full picture.

If You Don't Have a Visa Credit Card

You don't need the Costco co-branded card to shop at Costco — you just need any Visa credit card. A basic Visa from your bank, a travel rewards Visa, or a cash-back Visa all work at the register. The acceptance policy is about the network (Visa), not about which specific Visa card you carry.

That said, shoppers who frequently spend at Costco — especially on gas, since many Costco locations have fuel stations — sometimes find that a card optimized for warehouse or gas spending earns more over time than a generic flat-rate card. That calculation depends on your actual spending mix. 💡

The Gap That Only Your Profile Can Fill

Here's what the policy alone doesn't answer: which Visa card actually belongs in your wallet for Costco runs.

Someone with a long credit history, low utilization, and strong scores is looking at a meaningfully different set of options than someone building credit from scratch or recovering from past delinquencies. The first person might qualify for a premium rewards Visa with elevated earning rates. The second might be best served by a secured Visa card — which does work at Costco's register — while building toward better options.

The mechanics of Costco's payment policy are fixed and clear. What varies is your own credit profile, and that's the piece that determines which Visa card you're actually positioned to carry — and how much those warehouse trips are really working for you. 🛒
