Short answer: Costco gas stations accept credit cards, but only Costco credit cards and certain other payment methods. Visa, Mastercard, American Express, and Discover are not accepted at the pump.
This limitation surprises many shoppers, so it's worth understanding what payment options actually work, why Costco has this policy, and how it might affect your decision to buy gas there.
Costco gas pumps accept:
What they do not accept: regular Visa, Mastercard, American Express, or Discover credit cards—even if you're a Costco member.
Costco's payment policy at gas pumps stems from a long-standing partnership with Visa. In 2006, Costco and Visa ended their relationship for in-warehouse purchases, but the gas station agreement included its own terms. Over time, Costco introduced its Costco Anywhere Visa Card as the primary credit card option at the pump.
This exclusivity serves Costco's interests: it encourages membership loyalty and gives them data on purchasing patterns. For consumers, it means if you want to earn rewards on gas purchases using a credit card, you need the Costco-branded card specifically.
If you don't have a Costco Visa card, mobile wallets offer flexibility. Many digital payment apps—including Apple Pay, Google Pay, Samsung Pay, and others—allow you to add your personal credit or debit cards, then use those wallets at the pump. This effectively lets you pay with non-Costco cards, though the underlying payment method runs through your wallet.
Not all Costco locations support mobile wallets at the pump yet, so availability varies by location and gas pump model.
Your debit card works at any Costco gas pump without the credit card limitations. Similarly, cash payments are accepted at most locations, though fewer pumps now support cash-only transactions as digital payments become standard.
The credit card restriction affects how you might accumulate rewards:
For people who prefer to use their existing rewards credit cards, Costco gas may be less attractive than other stations that accept any major card.
Costco occasionally updates its gas station technology. Older pumps may have different payment capabilities than newer ones. If you're unsure whether a specific Costco location accepts mobile wallets or has a particular pump setup, it's worth checking with the station attendant or calling ahead—policies and equipment vary slightly by location.
Costco gas does accept credit cards, but only under specific conditions. If you're a Costco member without their Visa card, you can still pay using a debit card, cash, or a mobile wallet linked to your preferred payment method. The limitation mainly affects credit card rewards optimization—an important factor if maximizing cash back is part of your decision-making process.
