Can You Use a Credit Card at Costco?
Yes — but with one important catch. Costco only accepts Visa credit cards in its warehouses and on Costco.com. If you're carrying a Mastercard, American Express, or Discover, you won't be able to use it at the register. This policy has been in place since 2016, when Costco ended its long-running partnership with American Express and switched exclusively to Visa.
Understanding why this matters — and how to make it work for you — depends on what's in your wallet and what kind of credit card user you are.
Why Costco Only Takes Visa
Retailers negotiate directly with card networks over interchange fees — the small percentage of each transaction that goes to the card issuer. Costco, known for its obsession with keeping costs low, struck an exclusive deal with Visa that gives it favorable processing rates in exchange for accepting only Visa-branded cards.
This isn't a judgment on your card's quality. It's a business arrangement. Many excellent cards — including some top-tier rewards cards — run on networks other than Visa, so plenty of savvy cardholders hit this wall on their first Costco trip.
What Payment Methods Does Costco Accept?
Here's a clear breakdown of what works and what doesn't at Costco warehouses and on Costco.com:
| Payment Type | Accepted In-Warehouse | Accepted Online |
|---|---|---|
| Visa credit cards | ✅ Yes | ✅ Yes |
| Mastercard credit cards | ❌ No | ❌ No |
| American Express credit cards | ❌ No | ❌ No |
| Discover credit cards | ❌ No | ❌ No |
| Visa debit cards | ✅ Yes | ✅ Yes |
| Mastercard debit cards | ✅ Yes | ✅ Yes |
| PIN-based debit (any network) | ✅ Yes | N/A |
| Cash | ✅ Yes | ❌ No |
| Costco Shop Cards (gift cards) | ✅ Yes | ✅ Yes |
| EBT/SNAP | ✅ Yes | ✅ Yes |
| Personal checks | ✅ Yes | ❌ No |
💡 One nuance worth knowing: debit cards are less restricted than credit cards. Mastercard debit works fine in-warehouse even though Mastercard credit does not. The Visa-only rule applies specifically to credit card networks.
The Costco Anywhere Visa Card
Costco has its own co-branded credit card — the Costco Anywhere Visa® Card by Citi. Since it runs on the Visa network, it works seamlessly at any Costco location. It also earns rewards on gas, restaurants, travel, and Costco purchases.
That said, a co-branded store card isn't automatically the right card for everyone. Whether it makes sense depends on how frequently you shop at Costco, what rewards structure fits your spending, and whether you'd qualify for comparable or better rewards through a general-purpose Visa card instead.
Your Options If You Don't Have a Visa Credit Card
If your current credit cards aren't Visa, you have a few paths:
Use a non-credit alternative. Your Mastercard debit card, PIN debit, cash, or a Costco Shop Card all work fine. You won't earn credit card rewards, but you'll still get through checkout.
Open a Visa credit card. This is where your personal credit profile enters the picture. Visa-branded cards exist across the entire credit spectrum — from secured cards designed for people building credit from scratch to premium travel rewards cards that require strong credit histories.
Use a mobile wallet carefully. Apple Pay, Google Pay, and Samsung Pay are accepted at many Costco locations — but the underlying card still needs to be Visa. The network restriction doesn't disappear because you're tapping your phone.
Which Visa Card Is Right for You? That Depends on Your Profile 🔍
This is where general information can only take you so far. Visa credit cards vary enormously in their requirements, benefits, and costs. Factors that determine which cards you'd likely qualify for — and which would actually benefit you — include:
- Credit score range: Scores are generally bucketed into tiers (poor, fair, good, very good, exceptional), and issuers use these ranges as rough filters. A score in the mid-600s opens different doors than a score in the mid-700s.
- Credit history length: A thin file with only a year of history is evaluated differently than a decade-long track record, even if scores look similar on paper.
- Credit utilization: How much of your available revolving credit you're currently using affects both your score and how issuers perceive risk.
- Income and debt load: Issuers consider your ability to repay, not just your score. High income with manageable debt is viewed differently than the same score with significant existing obligations.
- Recent hard inquiries: Applying for multiple credit products in a short period can signal risk to issuers, regardless of your underlying score.
A Visa card that earns strong rewards and carries no annual fee might be well within reach for one reader — and a stretch for another with a similar score but a thinner credit history.
What This Means in Practice
If you already have a Visa credit card, the answer to "can I use a credit card at Costco?" is simply yes. Bring your Visa, use it like any other retailer.
If you don't have a Visa credit card, whether getting one is straightforward or more of a process comes down entirely to where your credit profile stands right now — your score, your history, your current utilization, and what issuers see when they pull your file. Those numbers tell a story that general information can't tell for you.
