Does Costco Accept Discover?

🏬💳

Costco Official Policy • Verified March 2026

Plain language facts from Costco’s official customer service page, major financial publications, and Discover’s own website — so you never get caught off guard at the checkout line.

🏪 The Direct Answer

No — Discover Credit Cards Are NOT Accepted at Costco

Costco warehouses and gas stations in the United States accept Visa credit cards only. Discover credit cards are declined at every in-store checkout lane, at the gas pump, and on Costco.com — effective since 2023 when Costco removed Discover from online purchases as well.

✅ One exception: a Discover-branded debit card used with a PIN may work in-store if your bank routes it through a PIN-debit network — but this is unreliable and Costco does not guarantee it. Have a backup payment ready.

💡 10 Key Things Every Costco Shopper Should Know About Discover

Costco’s payment rules have changed multiple times over the decades — from Discover, to American Express, to Visa — and many loyal members understandably get confused. Here is everything confirmed from Costco’s own official customer service page and verified by major financial publications, written in plain language so you can shop with confidence.

1
Does Costco accept Discover credit cards in-store? No — Discover credit cards are declined at every U.S. Costco warehouse.
Costco’s official customer service page lists only Visa credit cards, PIN-based debit cards, cash, checks, EBT, and Costco Shop Cards as accepted in-store. Discover, Mastercard, and American Express credit cards are all excluded. If you present a Discover credit card at the register, it will be politely declined — no exceptions.
2
Can I use my Discover card on Costco.com? No — Discover was removed from Costco.com in 2023.
There was a period when Costco.com accepted Discover cards for online purchases. That ended in 2023. Costco’s website now accepts Visa and Mastercard credit cards only. American Express and Discover are not accepted online, in the Costco app, or in-store. This is confirmed by Costco’s official payment page updated March 2, 2026.
3
What about my Discover debit card — does that work at Costco? Possibly — but only as a PIN debit transaction, and it is not guaranteed.
Costco accepts “most PIN-based debit/ATM cards” regardless of network. If your Discover debit card is processed through a PIN-debit network (by entering your PIN at the keypad), it may be accepted. However, this is not guaranteed — the result depends on how your bank routes the transaction. Always have a backup payment method such as cash, a Visa card, or a Costco Shop Card when shopping with a Discover debit card.
4
Why doesn’t Costco accept Discover? An exclusive contract with Visa — designed to lower prices for all members.
Costco negotiated an exclusive deal with Visa in 2016 to drastically reduce the “interchange fees” it pays to process credit card transactions — from the typical 2% to 3% range down to below 0.5% per transaction. By guaranteeing Visa exclusive access across hundreds of stores and billions in purchases, Costco keeps its operating costs low and passes those savings to members through lower shelf prices. Discover, Mastercard, and American Express were all excluded from this arrangement.
5
Did Costco ever accept Discover cards in the past? Yes — Discover was Costco’s very first credit card partner in the 1990s.
Before American Express, Costco actually accepted Discover as one of its earliest credit card options. The retailer then moved to an exclusive arrangement with American Express that lasted from 1999 to 2016. In June 2016, Costco switched to Visa as its sole credit card partner — ending acceptance of Amex in-store and, eventually, Discover online as well. Many longtime members remember one or more of these past arrangements, which is why the question still comes up so often today.
6
What credit cards does Costco actually accept? Any Visa credit card — from any bank or credit union — works at every Costco.
The Visa requirement applies to the network, not the issuing bank. Any card with the Visa logo — from Chase, Bank of America, a local credit union, or anywhere else — is accepted. This includes the store’s own co-branded Costco Anywhere Visa® Card by Citi, which earns extra cash back on Costco purchases, gas, and dining. If you have a Visa card from any source, you are set for every Costco checkout, gas pump, and food court.
7
What is the best workaround for Discover cardholders who shop at Costco? Buy a Costco Shop Card using your Discover card on Costco.com — then use it in-store.
Wait — Costco.com no longer accepts Discover credit cards, as noted in Takeaway #2. However, if you have a Discover-linked account you can use elsewhere (such as PayPal if accepted, or a bank transfer), you can preload a Costco Shop Card (essentially a Costco gift card) and use it for in-store purchases. The most reliable workaround in today’s policy is simply carrying a Visa-branded debit card from your checking account for Costco trips, or using cash. See the Workarounds section below for the full list of options.
8
Does Costco accept Discover at the gas station? No — Costco gas stations follow the same Visa-only credit card rule.
Costco gas stations accept Visa credit cards, PIN-based debit cards, and Costco Shop Cards only. Discover credit cards will be declined at the pump just as they are at the warehouse register. The same exception as in-store applies: if you have a Discover-branded debit card and can enter your PIN, it may process through the PIN-debit network — but this is not guaranteed. Have a Visa debit card or Costco Shop Card as your backup for the gas pump.
9
Does Costco accept Apple Pay, Google Pay, or Samsung Pay with a Discover card linked? No — the underlying card linked to your mobile wallet must be a Visa to work in-store.
Costco does accept Apple Pay, Google Pay, and Samsung Pay in-store. But acceptance depends on the credit card linked to those digital wallets, not the wallet itself. If your Apple Pay or Google Pay is linked to a Discover credit card, it will be declined at Costco’s register just as the physical card would be. To use mobile pay at Costco, your wallet must have a Visa credit card linked. Visa debit cards linked to mobile wallets are also accepted.
10
Is there any way Costco’s Discover policy could change in the future? Possible but unlikely anytime soon — the Visa partnership is deeply embedded in Costco’s business model.
Costco’s exclusive partnership with Visa gives the retailer significantly lower processing fees that directly fund the low shelf prices members depend on. Changing to an open-network or multi-network policy would increase operating costs. Historically, Costco has always maintained single-network exclusivity — first Discover, then American Express for 17 years, and now Visa. Unless Discover or Mastercard could offer Costco comparable or better interchange terms, a policy change is considered unlikely in the near term. Always verify at Costco.com before shopping if you are uncertain.

🔧 If You Only Have a Discover Card — Here Are Your Best Options

⚠️ Plan Ahead Before Your Costco Trip

Running into a declined card at a packed Costco checkout is stressful and embarrassing. None of these workarounds are complicated — but they do require a small amount of planning before you leave home. Review the options below and choose the one that best fits your situation.

1
Use a Visa-branded debit card from your checking account (Best option)
The simplest solution. Most checking accounts come with a debit card — if yours has a Visa logo on it, it works at every Costco checkout lane and gas pump with no complications. If your current debit card is Mastercard-branded, it still works as a PIN debit in-store. If your debit card has the Discover logo only, bring a backup. Many free checking accounts at online banks and credit unions issue Visa debit cards at no cost.
2
Buy a Costco Shop Card in advance — use it like cash in the warehouse
A Costco Shop Card is Costco’s own gift card and is accepted at every warehouse checkout, at gas pumps, and online. You can load any amount you plan to spend. Purchase a Shop Card at any Costco location using a Visa card or via a method available to you. Once loaded, use it exactly like a debit card at the register — no special instructions needed. This is particularly convenient for members who do regular Costco runs and want to pre-budget their spending.
3
Pay with cash at the warehouse register
Cash is accepted at all in-store Costco warehouse checkout lanes. It is not accepted at gas pumps, car wash stations, or on Costco.com. For members who are comfortable carrying cash for a large Costco run, this is the most reliable non-card option. Withdrawing cash in advance at a free ATM from your bank or credit union avoids any ATM fees.
4
Write a personal check (for current Costco members)
Active Costco members can pay with a personal check at the warehouse register. Business members can use business checks. Checks are not accepted at gas stations or online. This works well for members who still carry a checkbook and prefer writing checks for larger purchases. You will need your current Costco membership card and the check must match the membership name.
5
Apply for any no-annual-fee Visa credit card for Costco trips
If you shop at Costco regularly enough, it may be worth simply having a Visa card in your wallet. Many Visa credit cards have no annual fee and earn cash back on purchases — even 1% to 2% back on everything. You do not need the Costco-branded Citi card specifically; any Visa from your bank, credit union, or a free online bank qualifies. A no-annual-fee Visa used only at Costco costs nothing to carry and solves the payment problem permanently.
6
Try your Discover debit card at PIN — but always have a backup
If your bank-issued debit card carries the Discover logo and is PIN-capable, it may work at Costco checkout if your bank routes the transaction through a PIN-debit network rather than the Discover credit network. This is inconsistent and depends entirely on your bank’s routing setup. Some members report success; others report declines. The safest approach: try it and have cash or another payment method ready in case it does not process. Never rely on this as your only option for a large cart of groceries.

💳 Visa Cards That Work at Costco — Practical Options

You do not need the Costco co-branded card to shop at Costco. Any Visa — credit or debit — works at every register and pump. Here are practical, lower-cost options worth considering alongside your Discover card.

Best No-Fee Costco Visa Costco Anywhere Visa® Card by Citi — The Dedicated Costco Card

No annual fee with a paid Costco membership. Earns 4% on eligible gas and EV charging (first $7,000/year), 3% on restaurants and travel, 2% on Costco purchases, and 1% on everything else. Rewards paid as an annual certificate redeemable for cash or merchandise in-store. The best rewards rate for dedicated Costco shoppers. Apply at Citi.com or any Costco warehouse.

Best Free Visa for Seniors Any Free Visa Debit Card from Your Checking Account

The simplest solution: check whether your current bank debit card carries the Visa logo. If it does, it is accepted at every Costco lane and pump at no extra cost. If you are looking for a free checking account with a Visa debit card, Ally Bank, Capital One 360, Axos Golden Checking (age 55+), and most credit unions all issue Visa debit cards with their free checking accounts. No credit check, no annual fee, no application complexity.

Best 2% Back Visa Citi Double Cash® Card — 2% Cash Back Everywhere Including Costco

Earns 2% cash back on all purchases (1% when you buy, 1% when you pay). No annual fee. Works at every Costco in-store and online. A straightforward cash-back Visa that pairs well with Costco membership without the restrictions of the co-branded card. Good choice for members who shop at Costco regularly but also want rewards on spending at other stores.

Best Seniors Over 55 Axos Bank Golden Checking Visa Debit — Age 55+ Free Account

The only nationally available checking account designed specifically for adults 55 and older issues a Visa-branded debit card accepted at Costco. Zero monthly fee, zero overdraft fee, 91,000 ATMs, and $8 monthly ATM reimbursement. Free personal checks included.

❓ Costco & Discover — Questions Answered Plainly

💡 What Is a Costco Shop Card and How Do I Get One?

A Costco Shop Card is Costco’s version of a prepaid gift card. It is accepted at every U.S. Costco warehouse checkout lane, at gas pumps, and on Costco.com. There is no expiration date and no fees. You can buy a Shop Card at any Costco warehouse register (using cash, a Visa debit or credit card, or another accepted payment method), or online at Costco.com using Visa or Mastercard. Once you have a Shop Card, it works exactly like a debit card at checkout — hand it to the cashier or insert it at the terminal. For anyone whose primary card is Discover, buying a Shop Card before a planned Costco trip is the cleanest workaround available today.

💡 Can I Use My Discover Card If I Link It to PayPal and Pay with PayPal at Costco?

No. Costco does not accept PayPal as a payment method in-store or online. PayPal is specifically listed among the payment types Costco does not accept, along with Buy Now Pay Later services like Afterpay. Linking your Discover card to PayPal does not create a workaround for Costco’s payment restrictions. The only reliable non-Visa options for in-store Costco purchases remain cash, PIN-based debit cards, personal checks (members only), EBT for eligible food items, and Costco Shop Cards.

💡 If I Get Declined at Costco, What Should I Say or Do?

Stay calm — it happens to many shoppers who are unaware of the Visa-only rule. The cashier is not making a personal judgment; it is a company-wide policy printed on signage at most Costco entrances. Simply say: “I wasn’t aware of the Visa-only policy — I’ll pay with cash instead,” or ask to put the items aside while you run to the ATM. Costco cashiers handle this situation every day and are courteous about it. For future trips, the simplest prevention is to confirm before leaving home that you have an accepted payment method in your wallet: any Visa card or debit card, a Costco Shop Card you’ve loaded in advance, or cash for in-store use.

💡 Does the Costco Rule Apply at Costco Canada or Costco in Other Countries?

No — Costco’s payment policy varies by country. In Canada, Costco’s exclusive credit card partner is Mastercard, not Visa. Canadian Costco warehouses accept Mastercard credit cards only (no Visa credit cards in-store). In other international Costco locations, different card networks may apply. The Visa-only rule described throughout this guide applies specifically to United States Costco locations. If you travel internationally and plan to shop at a Costco, always check that country’s Costco website for the current accepted payment methods before assuming your U.S. Visa or Discover card will work.

💡 Why Does Costco Keep Prices So Low — and Is the Payment Restriction Part of That?

Yes, directly. Costco’s entire business model is built around eliminating unnecessary costs and passing those savings to members through lower shelf prices and the annual Executive Member rebate. Credit card processing fees — called interchange fees — typically cost merchants 2% to 3% of every transaction. For a company processing billions of dollars in transactions annually, even shaving 1.5 percentage points off that fee rate saves tens of millions of dollars per year. By negotiating an exclusive deal with Visa, Costco reportedly reduced its interchange fees to below 0.5% per transaction. Those savings flow into the prices you see on the shelf. The payment restriction is an inconvenience for some shoppers but a meaningful financial strategy that helps keep Costco competitive on price.

📊 Understanding Costco’s Payment Policy — By the Numbers

📅 Visa Exclusivity Began

June 2016

Costco ended its 17-year American Express exclusive partnership and switched entirely to Visa as its sole credit card network. Discover and Mastercard have been excluded from in-store credit purchases since this date.

🌐 Discover Removed Online

2023

Costco removed Discover as an accepted payment method on Costco.com and the Costco app in 2023. Before then, Discover could be used for online purchases even though it was not accepted in-store. Today Discover is not accepted anywhere at Costco.

💲 Typical Credit Card Fee Rate

2% – 3%

The interchange fee most merchants pay to credit card networks per transaction. By negotiating an exclusive Visa deal, Costco reduced this below 0.5% — saving tens of millions per year and funding lower member prices.

✅ Cards Always Accepted In-Store

Visa Only

Any Visa-branded credit or debit card from any issuing bank works at every U.S. Costco warehouse and gas station. No specific bank is required — only the Visa network logo on your card.

🏦 Costco’s Payment History at a Glance

Costco has always operated on exclusive single-network credit card partnerships. The progression: early years — Discover cards accepted; 1999 to 2016 — American Express exclusive (the only credit card accepted in-store); June 2016 to present — Visa exclusive (Amex dropped entirely; Mastercard accepted online only; Discover accepted online until 2023, then removed). Understanding this history explains why so many longtime members are still surprised to have their Discover or American Express card declined — the policy has changed significantly over the decades.

📍 Plan Your Costco Trip

Before heading out, confirm you have an accepted payment method: a Visa credit or debit card, cash, a Costco Shop Card, or a PIN-based debit card from your checking account. Use the buttons below to find your nearest Costco or to check Costco’s official payment policy page directly.

✅ Five Things to Do Before Your Next Costco Trip

Check your wallet right now. Does any card in your wallet have the Visa logo? A Visa debit card from your checking account is all you need — no credit card required. If you have one, you are all set.
If no Visa card, get a Costco Shop Card before you go. You can load one at any Costco warehouse or ask a family member with a Visa card to buy one for you. It works exactly like cash at the register and never expires.
Know that your Discover debit card might work — but bring a backup. If your Discover debit card is PIN-capable, try it at checkout by entering your PIN. If it processes, great. If it declines, have cash or another method ready so you are not stranded.
Do not rely on Apple Pay or Google Pay linked to a Discover card. The digital wallet itself is not the issue — the linked card network is. Discover-linked mobile wallets will be declined. Re-link your mobile wallet to a Visa card before your Costco visit.
If you shop at Costco often, consider a no-annual-fee Visa credit card. Even a basic Visa with 1% to 2% cash back earns money back on every Costco trip. Many free options exist from credit unions and online banks with no income requirement and no annual fee.

⚠️ Three Common Misconceptions About Discover at Costco

“I used my Discover card at Costco years ago — it should still work.” Many members remember using Discover at Costco in the early days of their membership. Costco has changed its credit card policy multiple times over the decades. The current Visa-only policy has been in place since 2016 for in-store purchases, and Discover was removed from Costco.com in 2023. Past acceptance does not predict current acceptance.
“I enter my PIN, so any card should work.” Entering a PIN does not automatically make a Discover credit card acceptable at Costco. The PIN workaround applies only to debit cards, and even then it depends on how your bank routes the transaction. A Discover credit card — even entered as a PIN debit — will be declined because Costco’s system excludes the Discover network entirely for credit transactions.
“If Discover is accepted at 10 million merchants, why not Costco?” Discover is indeed one of the four major U.S. credit card networks and is widely accepted nationwide. The exception at Costco is specifically due to Costco’s exclusive contractual partnership with Visa — a business arrangement, not a reflection of Discover’s general acceptance. Discover itself acknowledges on its own website that Costco is among the merchants where its card is not accepted due to an exclusive partner agreement.
