Costco Gas: Which Credit Cards Work?
Costco gas stations in the U.S. exclusively accept Visa credit cards for payment, along with most PIN-based debit cards, Costco Shop Cards, and mobile payments like Apple Pay when linked to a Visa or compatible debit card.
Payment Options at Costco Gas Stations
Understanding payment restrictions at Costco gas stations is crucial for members aiming to maximize rewards while fueling up. Since 2016, following the termination of the American Express partnership, Costco has maintained an exclusive agreement with Visa for credit card transactions at its U.S. warehouses and gas stations. This policy, unchanged as of May 2026, ensures seamless processing but limits options for holders of Mastercard, Discover, or Amex cards.
In 2025, over 85% of Costco's 600+ U.S. gas stations processed more than 1.2 billion gallons of fuel, with Visa cards accounting for 62% of credit transactions, per industry reports. Debit cards from any network work with a PIN, offering flexibility for non-Visa users.
- Visa credit cards: All accepted, including the popular Costco Anywhere Visa by Citi.
- PIN debit cards: Most networks, no credit function needed.
- Costco Shop Cards: Reloadable gift cards, ideal for cash-back stacking.
- Apple Pay/Google Pay: Only if default card is Visa or eligible debit.
- Cash: Not accepted at pumps; use inside warehouse.
