Costco's payment policy is stricter than most retailers—not every credit card works there. Understanding what's accepted, why, and how this might affect your shopping matters if you're a member or considering membership.
Costco accepts only Visa credit cards for in-warehouse purchases and online orders. This has been the standard since 2016, when Costco ended its exclusive partnership with American Express and moved to Visa.
This means:
The one exception: American Express cardholders can still shop online at Costco.com, though not in physical warehouses.
If you don't have a Visa credit card, you still have options:
Cash is always accepted in-warehouse and remains one of the simplest ways to pay. Debit cards (including non-Visa debit cards) work at the register. Digital wallets like Apple Pay and Google Pay are accepted if they're linked to a Visa credit card, debit card, or another supported method.
Some Costco locations accept EBT cards for eligible members, though this varies by region and product category.
Costco's payment restrictions stem from its wholesale warehouse model and member-centric approach. By limiting card brands, Costco negotiates favorable processing fees, which keeps costs down across the business. The Visa partnership allows the company to pass savings to members rather than absorbing higher payment processing costs.
This also simplifies the payment system in warehouses and reduces fraud risk.
Your situation determines how much this policy affects you:
| Profile | Practical Impact |
|---|---|
| Visa cardholder | No friction—your card works everywhere Costco accepts cards |
| Mastercard or Discover user | You'll need to pay with cash or debit, or use a digital wallet if linked to an eligible card |
| American Express member | In-warehouse shopping requires cash/debit; online shopping via Amex works |
| No credit cards | Cash or debit card works fine; no membership barrier |
Consider these factors when deciding if Costco's payment policy affects your shopping experience:
How you typically pay. If you rely on a single credit card for rewards or budgeting, check whether it's Visa before joining.
Where you shop most. If you shop primarily online, American Express acceptance at Costco.com may matter more than warehouse restrictions.
Reward priorities. Some shoppers prioritize specific credit card benefits. Costco doesn't accept all cards, so you'll want to confirm whether your preferred card works before relying on it for purchases there.
Payment flexibility. If you're comfortable using cash, debit, or a digital wallet, the Visa-only rule has minimal practical impact.
Costco's credit card policy is straightforward but non-negotiable: Visa credit cards only in warehouses; cash, debit, and select digital wallets are also accepted. If you're an American Express cardholder interested in Costco membership, you can still shop online but not in-warehouse with your card.
This policy won't change your ability to be a Costco member, but it may influence how you pay when you shop. Knowing the rules upfront helps you avoid surprise friction at checkout.
