What Credit Cards Does Costco Accept? A Complete Guide

If you've ever pulled out the wrong card at a Costco checkout, you know the experience is mildly embarrassing and entirely avoidable. Costco has one of the most restrictive payment policies of any major retailer — but once you understand the logic behind it, navigating it becomes straightforward.

Costco Only Accepts Visa Credit Cards

At all Costco warehouse locations in the United States, only Visa-branded credit cards are accepted. Mastercard, American Express, and Discover credit cards are not accepted in-store. This has been the policy since 2016, when Costco ended its long-running exclusive partnership with American Express and moved to a co-branded arrangement with Visa through Citibank.

The reasoning is business-driven: card networks charge merchants a processing fee (called an interchange rate) on every transaction. Costco's entire model is built around keeping costs low and passing savings to members, so locking in a single network partner gives them leverage to negotiate favorable terms.

What About Debit Cards and Other Payment Methods?

Costco accepts a broader range of payment types beyond Visa credit:

The key distinction: debit cards from most major networks are generally accepted, but credit cards must carry the Visa logo.

Shopping on Costco.com Is Different 💻

The credit card rules are more flexible on Costco's website. Online, Costco accepts:

• Visa credit and debit cards
• Mastercard credit and debit cards
• Discover credit cards
• American Express credit cards

So if you have an Amex or Mastercard you prefer for online purchases, you can still use it at Costco.com — just not at the warehouse register.

The Costco Anywhere Visa Card: Built for Costco Shoppers

The card most closely associated with Costco is the Costco Anywhere Visa® Card by Citi. It's a co-branded card, meaning it's issued by a bank (Citi) but carries Costco branding and is designed around Costco membership.

Because it's a Visa, it's accepted anywhere in the warehouse. It also earns cash back rewards in categories like gas, dining, travel, and Costco purchases — though the specific reward rates are subject to change and worth verifying directly with Citi.

A few things worth knowing about this card:

• A valid Costco membership is required to apply
• Rewards are paid annually as a certificate redeemable at Costco warehouses (not as direct cash back to your account)
• It functions as a general-purpose Visa, accepted beyond Costco wherever Visa is welcome

Who Typically Qualifies?

Like most co-branded retail cards issued by major banks, the Costco Anywhere Visa generally targets applicants with good to excellent credit. What falls into those categories varies by scoring model, but lenders typically consider credit scores in the mid-to-upper range of the 670–850 band as favorable.

However, a credit score is only one piece of the approval picture.

What Card Issuers Actually Look At 🔍

If you're considering applying for the Costco Anywhere Visa — or any Visa card you plan to use at Costco — understanding how approvals work helps set realistic expectations.

Factors that typically influence credit card approvals:

• Credit score — A snapshot of your creditworthiness based on your credit history
• Credit utilization — What percentage of your available revolving credit you're currently using; lower is generally better
• Payment history — Whether you've paid bills on time, and how consistently
• Length of credit history — How long your accounts have been open on average
• Recent hard inquiries — Applying for multiple cards in a short window can signal risk to lenders
• Income and debt-to-income ratio — Issuers want confidence you can service the credit line
• Existing relationship with the issuer — If you already have accounts with Citi, that history may factor in

None of these variables works in isolation. Someone with a strong credit score but very high utilization may fare differently than someone with a slightly lower score and clean payment history across many years.

If Your Credit Profile Is Still Developing

Not everyone applying for a Costco Visa will have an established credit history. If your score is on the lower end, or your history is thin, a few things are worth understanding:

• Secured credit cards require a cash deposit as collateral and are often more accessible to those building or rebuilding credit. They're not co-branded warehouse cards, but using one responsibly helps build the profile needed to qualify for better cards later.
• Authorized user status on someone else's account can add positive history to your credit file without requiring a new application.
• Credit utilization improvements — paying down existing balances — can meaningfully shift your score in a relatively short timeframe compared to other factors.

The Variable That Makes It Personal

Costco's card acceptance policy is simple and fixed: Visa credit cards only in the warehouse, broader options online. That part applies to everyone equally.

But whether a particular Visa card — especially the co-branded Costco Anywhere Visa — makes sense to apply for, and whether you're likely to qualify for favorable terms, depends entirely on where your credit profile currently stands. Two people walking into the same Costco checkout line could be in very different positions when it comes to the card in their wallet. The policy is uniform; the credit picture behind each card is anything but.
