What Credit Cards Does Costco Accept in 2026? (In-Store, Online, and Gas)

Costco has an exclusive agreement with Visa for credit card acceptance. This means the card in your wallet matters more at Costco than almost any other retailer. Here is exactly what is accepted and where.

Costco Payment Methods by Location

The key rule: In the warehouse, only Visa credit cards work. At the gas station and online, more options are available.

Why Only Visa?

Costco has an exclusive co-brand and acceptance agreement with Visa (since 2016, replacing a long-standing American Express partnership). This means:

• The Costco Anywhere Visa (issued by Citi) is the only co-branded Costco credit card
• Only Visa-network credit cards are accepted at warehouse registers
• This is a business-level agreement, not a technical limitation

This matters for your card strategy. If your best rewards card is a Mastercard or Amex, you cannot use it inside Costco warehouses.

Best Visa Credit Cards for Costco

Since you need a Visa, here are the strongest options:

Costco Anywhere Visa — The default choice. 4% gas (up to $7k/year), 3% dining and travel, 2% at Costco, 1% everything else. No annual fee (requires Costco membership). See our Costco Calculator for your exact cash back.

Chase Sapphire Preferred — 3x dining, 5x Chase Travel portal. Not Costco-specific, but earns well on dining/travel and pairs with the Costco Visa for a strong two-card setup.

Chase Freedom Unlimited — 1.5% on everything (including Costco), 3% on dining. A simple Visa option if you do not want the Costco co-brand.

Common Questions

Can I use my Amex Gold at Costco? No. The Amex Gold is not a Visa card. It will not work at Costco warehouses, online, or at gas stations.

Can I use debit at Costco? Yes. Debit cards from any network (Visa, Mastercard, etc.) are accepted in-store with a PIN. Debit is not accepted for online orders.

Does Costco give cash back on debit? No. Costco does not offer cash back at the register on debit purchases.

Can I use PayPal at Costco? Online only. PayPal is accepted on Costco.com but not at warehouse registers or gas stations. For a PayPal strategy, see our Costco PayPal Debit Card guide.

Does the Costco Executive membership 2% rebate stack with the Costco Visa? Yes. The Executive 2% rebate and the Costco Visa's 2% cash back are separate programs that stack for an effective 4% back at Costco. See our Costco Executive Breakeven Analysis for the math.

The Bottom Line

Costco only accepts Visa credit cards in-store. Plan your wallet accordingly. If your primary rewards card is a Mastercard or Amex, you will need a Visa card specifically for Costco warehouse purchases. The Costco Anywhere Visa is the default choice, but it is not always the best option — our optimizer can show you which Visa card earns the most at Costco based on your overall spending.
