What Credit Cards Does Costco Accept?

🔑 10 Key Takeaways: Quick Answers

What credit cards does Costco accept? Only Visa credit cards are accepted at U.S. Costco warehouse locations.

Does Costco accept Mastercard? No — not for credit card transactions in-store. However, Mastercard is accepted on Costco.com for online purchases.

Does Costco accept American Express? No. Costco ended its 16-year exclusive relationship with AmEx in 2016 and has not accepted it since.

Does Costco accept Discover? No — not in-store. Discover can be used for online orders on Costco.com in some cases.

Does Costco take debit cards? Yes! Costco accepts most Pin-based debit/Atm cards from any network — Visa, Mastercard, Discover, or otherwise.

Does Costco accept Apple Pay? Yes — Apple Pay, Google Pay, and Samsung Pay are all accepted in-store.

Why does Costco only take Visa? Costco negotiated an exclusive deal with Visa for processing fees of only 0.4%, compared to the industry standard of 1.3%–3.5%.

Will Costco ever accept other credit cards? The current exclusive agreement with Visa extends through June 2029, so no changes are expected before then.

Is it the same in every state, including Texas? Yes. The Visa-only credit card policy is uniform across all 50 states.

What if I don’t have a Visa credit card? Use a debit card (any network), cash, Costco Shop Card, Apple Pay linked to a debit card, or personal check.

💳 Costco Only Accepts Visa Credit Cards in-Store — and the Math Behind This Decision Is Staggering

Let’s talk numbers, because the financial engineering behind this decision is genuinely fascinating.

Most credit card merchant fees range from 1.5% to 3.5% per transaction. On Costco’s roughly $250 billion in annual net sales, even a 2% fee would cost the company $5 billion per year in processing charges. That’s more than Costco’s entire net income.

Here’s how the exclusive Visa deal changes everything:

💳 Card Network	📊 Typical Merchant Fee	💰 Costco’s Annual Cost (est. on $250B sales)
American Express	2.5%–3.5%	$6.25B–$8.75B 😱
Discover	1.5%–2.5%	$3.75B–$6.25B
Mastercard	1.5%–2.5%	$3.75B–$6.25B
Visa (standard rate)	1.3%–2.5%	$3.25B–$6.25B
Visa (Costco’s exclusive deal)	<0.4%	<$1B 🔥

The arrangement allows Costco to pay near-zero interchange fees on in-warehouse Visa transactions, subsidized by Citi and Visa. In practical terms, this is why a gallon of milk, a rotisserie chicken, or a Kirkland Signature product costs less at Costco than virtually anywhere else — the credit card savings are baked into every price tag on every shelf.

When Costco’s previous partner, American Express, was charging approximately 0.6% in merchant fees, that still added up to about $180 million per year. Visa came in below that number, and the deal was sealed.

💡 Critical insight: The current exclusive co-brand agreement between Costco, Citi, and Visa was originally set to expire in 2026, but Costco has exercised its right to extend the term through June 19, 2029. This means the Visa-only policy is locked in for at least three more years.

❌ Costco Does Not Accept Mastercard, Amex, or Discover for Credit — Here’s What Gets Declined

This is the section that saves you embarrassment at the checkout counter. Here’s the definitive list of what does not work for credit card payments inside a Costco warehouse:

❌ Declined at Costco In-Store	📌 Why
Mastercard credit cards	Excluded by Visa exclusivity agreement
American Express credit cards	Partnership ended in 2016 after Costco and AmEx failed to reach a new deal
Discover credit cards	Not part of the exclusive network agreement
Any credit card linked via Apple Pay that isn’t Visa	The mobile wallet passes through the card network
Store credit cards (Target, Amazon, etc.)	Not Visa-branded
Prepaid credit cards (non-Visa)	Must be Visa network

The one exception that confuses people: The Visa-only restriction applies only to credit cards — Costco accepts most Pin-based Atm/debit cards from any network. So if you have a Mastercard debit card, it works perfectly fine at Costco. It’s the credit function that gets blocked.

🤔 Why Doesn’t Costco Accept Mastercard? It’s Not Personal — It’s a $5 Billion Decision

Here’s the thing most people don’t realize: Costco’s decision to reject Mastercard isn’t about the quality of Mastercard as a payment network — it’s about the financial structure of an exclusivity deal that makes it impossible to accept competing cards.

When Costco signs an exclusive agreement with Visa, the deal works like this:

Visa gives Costco dramatically reduced interchange fees (below 0.4%)
In exchange, Costco agrees to accept only Visa credit cards in U.S. warehouses
Citi issues the co-branded Costco Anywhere Visa Card, driving new cardholders to both Visa and Citi
Costco gets additional revenue from the co-brand partnership arrangement

By signing an exclusive deal with Visa, Costco secured significantly lower interchange fees than what Mastercard, Discover, or American Express could offer without a similar guarantee of exclusivity. If Costco accepted all four networks, none of them would offer the rock-bottom rate that Visa provides exclusively.

Interestingly, this approach isn’t entirely uniform worldwide — in Canada, Costco actually accepts Mastercard, because the partnership dynamics and regulatory environment differ in each country.

✅ The Complete List of Every Payment Method Costco Accepts in 2026

🕰️ Why Doesn’t Costco Accept Amex Anymore? The $180 Million Breakup Explained

The Costco-American Express split in 2016 was one of the most dramatic breakups in retail history. Here’s what actually happened:

Costco and American Express had a partnership that dated back 16 years, making AmEx the only credit card accepted at Costco warehouses from 1999 through March 2016. Before that, Costco exclusively accepted Discover.

But when renewal negotiations began, the numbers fell apart. The AmEx merchant fee was approximately 0.6% for every Costco member transaction — which, while below the national average, added up to roughly $180 million per year for Costco.

AmEx wanted to maintain (or even increase) its fee structure. Costco wanted it lower. Neither side blinked.

AmEx chief executive Kenneth Chenault stated at the time that they couldn’t accept Costco’s financial terms, saying some conditions would have meant taking on more risk than AmEx was comfortable with.

Visa swooped in with a processing fee below 0.4% — dramatically undercutting AmEx — and the deal was done. Visa replaced American Express as the credit card network, and Citi became the exclusive issuer of the co-branded Costco credit card.

📅 Year	💳 Costco’s Exclusive Credit Card Partner	📊 Approx. Merchant Fee
Pre-1999	Discover	~1.5%
1999–2016	American Express	~0.6%
2016–2029+	Visa	<0.4% 🔥

For shoppers who still carry AmEx: Your American Express card will not work anywhere at Costco — not in the warehouse, not at the gas pump, and not even on Costco.com. It’s a complete exclusion.

🗺️ What Credit Cards Does Costco Accept in Texas? (Spoiler: the Same as Every Other State)

This is one of the most frequently searched questions, and the answer is simple: Costco’s credit card policy is identical in all 50 states, including Texas. There are no state-by-state variations for payment acceptance.

Whether you’re shopping at a Costco in Houston, Dallas, San Antonio, Austin, Fort Worth, or El Paso, you’ll face the exact same rules:

✅ Visa credit cards accepted
✅ All debit cards accepted
✅ Cash, checks, Shop Cards, mobile payments accepted
❌ Mastercard, AmEx, Discover credit cards not accepted

The confusion often comes from the fact that certain state-specific laws affect other Costco policies (like alcohol sales to non-members or Snap/Ebt restrictions), but the credit card policy is a nationwide corporate agreement with Visa that applies uniformly.

📱 Costco Accepts Apple Pay, Google Pay, and Samsung Pay — but There’s a Catch Most People Miss

Costco warehouses accept Apple Pay, Google Pay, and Samsung Pay at all in-store registers, including self-checkout. This is great news for mobile payment fans.

But here’s the catch: When you tap your phone or watch to pay at Costco, the transaction still passes through your underlying card’s payment network. That means:

📱 Mobile Wallet Scenario	✅ Works at Costco?
Apple Pay linked to a Visa credit card	✅ Yes
Apple Pay linked to a Mastercard debit card	✅ Yes (processes as debit)
Apple Pay linked to a Mastercard credit card	❌ No — Mastercard credit is blocked
Google Pay linked to a Discover credit card	❌ No — Discover credit is blocked
Samsung Pay linked to any debit card	✅ Yes

At gas stations, only Apple Pay is accepted for mobile payments — Google Pay and Samsung Pay don’t work at the pumps, even though they work inside the warehouse.

💡 Pro tip: If your primary credit card isn’t Visa but you have a debit card from any bank, link that debit card to Apple Pay or Google Pay and you’ll be able to tap-to-pay at Costco without any issues. The debit transaction processes as a Pin-based payment, bypassing the Visa-only credit card restriction entirely.

🧮 The Costco Anywhere Visa Card: Is It Actually Worth It in 2026?

The Costco Anywhere Visa Card by Citi is Costco’s co-branded credit card, and it’s designed to reward members who do a significant portion of their spending at Costco. Here’s the rewards structure:

🏷️ Spending Category	💰 Cashback Rate	📌 Cap/Limit
Costco gas stations	5%	First $7,000/year combined with Ev charging, then 1%
Non-Costco gas + Ev charging	4%	Same $7,000 combined cap
Restaurants + eligible travel	3%	Unlimited
Costco + Costco.com purchases	2%	Unlimited
Everything else	1%	Unlimited

No annual fee (beyond your Costco membership), no foreign transaction fees. Rewards are issued as an annual certificate redeemable at Costco warehouses.

However, criticism of the card has grown significantly. As one analysis noted, the Costco Visa was a great credit card when it launched, but the broader credit card market has become increasingly competitive since 2016. Several non-Costco Visa cards now offer 2% flat cashback on everything with no annual fee and no warehouse membership required.

🔄 7 Smart Workarounds If You Don’t Have a Visa Credit Card

Don’t have a Visa? Here are the easiest ways to shop at Costco without one:

1. Use your debit card. Costco accepts most debit cards from any network — even Mastercard-branded debit cards work perfectly as Pin-based transactions.

2. Link a debit card to Apple Pay or Google Pay. Tap-to-pay at the register using your debit card through your phone’s mobile wallet.

3. Pay with cash. Old-fashioned? Yes. Always accepted? Also yes.

4. Use a Costco Shop Card. Any member can purchase Shop Cards loaded with $25–$2,000, and they work like prepaid gift cards at any register, gas pump, or online.

5. Shop on Costco.com with Mastercard. Online orders accept both Visa and Mastercard, so Mastercard holders can order online for delivery.

6. Write a personal check. Costco accepts personal checks from current members with valid photo Id. Not the fastest checkout, but it works.

7. Apply for a Visa credit card. Several excellent no-annual-fee Visa cards exist outside the Costco ecosystem, including the Chase Freedom Unlimited (1.5% cashback everywhere) and the Wells Fargo Active Cash (2% cashback everywhere).

🔮 Will Costco Ever Accept Mastercard or Other Credit Cards? Here’s What We Know

The current Visa exclusivity deal has been extended through June 19, 2029, per Sec filings. Until that date, there is virtually zero chance Costco will accept Mastercard, American Express, or Discover credit cards in-store.

There are no public indications that Costco plans to accept Mastercard or other credit networks, as the current Visa arrangement is highly beneficial for both parties.

Could things change after 2029? Theoretically, yes. But consider this:

Costco has never accepted multiple credit card networks simultaneously in its entire history
The exclusive model has been Costco’s strategy since the company’s founding — first Discover, then AmEx, now Visa
The exclusivity model is fundamentally what allows Costco to charge near-zero processing fees and maintain its legendary low prices

The most likely scenario after 2029 is that Costco renews with Visa on similar terms, or potentially switches to a different single partner if a competitor offers better rates. The idea of Costco accepting all major credit cards simultaneously would fundamentally break their pricing model.

❓ Frequently Asked Questions

Can I use my Mastercard at Costco if I run it as credit? No. Mastercard credit transactions are declined at all Costco warehouse registers. You can use a Mastercard-branded debit card if it processes as a Pin-based debit transaction.

Does the Costco food court accept credit cards? Yes — Visa credit cards and debit cards work at the food court. Mobile payments from Apple Pay, Google Pay, and Samsung Pay are also accepted at the food court.

Can I use Discover at Costco in any way? Not in-store. Discover credit may work on Costco.com for certain online purchases, and a Discover-branded debit card should work in-store if processed as Pin-based.

Why does Costco accept Mastercard online but not in-store? Costco.com has a broader payment acceptance policy than warehouses, likely because online transactions have different fee structures and competitive dynamics. The exclusivity deal with Visa specifically targets in-warehouse and gas station transactions.

If I have Fsa or Hsa funds, can I use them at Costco? Fsa/Hsa Visa or Mastercard debit cards are accepted at Costco pharmacies, optical departments, and hearing aid departments only — not at regular warehouse registers.

Is the Costco credit card policy different in Canada? Yes. Costco Canada accepts Mastercard rather than Visa, because the international partnership arrangements differ by country.

How much does Costco save by only accepting Visa? Costco pays transaction fees of approximately 0.4% compared to the industry standard of 1.3% to over 3%. On $250 billion in annual sales, this saves Costco billions of dollars — savings that translate directly into lower prices on every product in the warehouse.

What’s the best non-Costco Visa card for shopping at Costco? Any Visa card with 2% flat cashback (like Wells Fargo Active Cash or U.S. Bank Altitude Go) gives you comparable or better rewards than the Costco Anywhere Visa’s 2% in-store rate — without tying your rewards to an annual certificate redeemable only at Costco.

The bottom line? Costco’s Visa-only credit card policy isn’t going anywhere before 2029 at the earliest. It’s the financial backbone of how Costco keeps its prices lower than virtually every competitor. The workaround is simple: carry a Visa credit card, use any debit card, or pay with cash. The minor inconvenience at the register is what funds the massive convenience of paying less for everything else in the warehouse.
