Costco Gas Payment Options: Which Cards Are Allowed
Costco gas stations accept Visa credit cards, most debit/ATM cards (including those with PINs), and Costco Shop Cards, but they do not accept Mastercard, American Express, or Discover for fuel purchases. This payment policy has been in place across U.S. Costco locations since the retailer's exclusive Visa partnership began in June 2016, and it remains one of the most common points of confusion for first-time users at Costco fuel pumps.
Accepted payment methods at Costco gas stations
The Costco fuel policy is intentionally streamlined to reduce transaction fees and keep gas prices lower than competitors. According to Costco's 2024 annual report, limiting card networks helps the company save an estimated 0.4%-0.7% per transaction, savings that are partially passed on to members through lower fuel prices.
- Visa credit cards (including Costco Anywhere Visa® Card by Citi)
- Debit cards with PIN (Visa or other networks processed as debit)
- ATM cards with PIN capability
- Costco Shop Cards (gift cards usable without a membership at the pump)
- Mobile wallets linked to Visa (Apple Pay, Google Pay, Samsung Pay at select locations)
Each payment terminal system is designed for speed, processing transactions in under 10 seconds on average, based on internal Costco operational benchmarks shared during a 2023 investor call.
Cards not accepted for Costco gas
Costco's exclusivity agreement with Visa means several widely used cards are not accepted at the pump. This policy applies specifically to U.S. warehouses; international locations may differ.
- Mastercard credit cards
- American Express cards (formerly accepted before 2016)
- Discover cards
- Cash (not accepted at the pump under any circumstance)
The restriction on non-Visa networks is one of the few downsides cited in customer satisfaction surveys, though Costco still ranked #1 in fuel value perception in a 2025 Consumer Fuel Insights report with 92% approval.
How to pay for gas at Costco
The process for using a Costco gas pump is standardized across nearly all U.S. locations, ensuring consistent user experience regardless of warehouse size or region.

Why Costco only accepts Visa
The exclusive Visa agreement was signed in 2015 and launched in June 2016, replacing a long-standing partnership with American Express. Costco executives stated that Visa offered significantly lower transaction fees, enabling the retailer to maintain its famously low margins on fuel.
"Our agreement with Visa allows us to continue delivering exceptional value to our members," said Richard Galanti, Costco CFO, during the 2016 transition announcement.
This exclusive card partnership is a cornerstone of Costco's business model, which caps markup on most goods-including gasoline-at around 14%.
Do you need a membership to buy Costco gas?
Most Costco gas stations require an active membership, but there is a workaround using Costco Shop Cards. This nuance in the membership requirement policy is often overlooked by casual shoppers.
- Members: Full access to all gas stations
- Non-members: Can use Costco Shop Cards only
- Membership scan required before payment unless using Shop Card
As of 2025, Costco operates over 700 gas stations globally, with more than 500 in the United States, making membership-based fueling a major driver of customer retention.
Tips to avoid payment issues
Payment failures at Costco pumps are rare but can happen if users are unaware of restrictions. Understanding these fuel payment tips can prevent delays and frustration.
- Always bring a Visa credit card if using credit
- Ensure your debit card has a working PIN
- Check mobile wallet compatibility beforehand
- Keep your membership card accessible
- Use a Costco Shop Card if you don't have a membership
Industry data from 2024 shows that fuel transaction declines at Costco are 35% lower than at traditional gas stations, largely due to simplified payment acceptance.
