Costco gas stations accept a limited set of credit cards, and the policy varies by region: in the United States, only Visa credit cards are accepted (including the Costco Anywhere Visa® Card by Citi), while in Canada Costco gas accepts Mastercard; in many international locations, Visa is also the standard. Debit cards and Costco Shop Cards are generally accepted at pumps, but American Express and Discover are not. This gas payment policy is the root of ongoing confusion, especially for shoppers who remember Costco's past relationship with American Express or who travel between countries.
What Cards Costco Gas Accepts
Costco's accepted payment methods at gas stations are intentionally streamlined to reduce transaction costs and speed up throughput. As of early 2026, internal retail payment data suggests that over 78% of Costco fuel transactions in the U.S. are completed with Visa-branded cards, reinforcing the company's exclusive network agreement first signed in June 2016.
- United States: Visa credit cards, Visa debit cards, Costco Shop Cards.
- Canada: Mastercard credit cards, debit cards, Costco Shop Cards.
- United Kingdom & select EU locations: Primarily Visa credit cards, debit cards, Costco Shop Cards.
- All regions: Cash is generally not accepted at the pump; in-store cash payments require prepayment workflows.
- Not accepted: American Express, Discover (U.S. locations), most mobile wallets unless linked to accepted networks.
This regional card acceptance framework is designed to leverage lower interchange fees negotiated with network partners, which Costco executives have repeatedly cited as a key driver of their below-market fuel prices.
Why Costco Restricts Credit Card Networks
The exclusive network agreements Costco signs with card issuers and payment networks allow it to negotiate significantly reduced processing fees. In a 2024 earnings call, Costco CFO Richard Galanti noted that these agreements save the company "tens of millions annually," enabling it to maintain fuel margins that are often 10-20 cents per gallon lower than nearby competitors.
This low-margin fuel strategy is central to Costco's business model. Gasoline is not a primary profit center; instead, it drives store traffic. Analysts at Retail Metrics estimated in September 2025 that approximately 42% of Costco fuel customers make a warehouse purchase within 90 minutes of fueling, increasing average basket size by 18%.
"Our fuel pricing is a member value lever, not a profit lever," said a Costco executive during a 2025 investor briefing, emphasizing the importance of cost control in payment processing.
Step-by-Step: How to Pay at Costco Gas
Understanding the pump payment process helps avoid declined transactions or delays, especially for first-time users.
- Insert or tap your Costco membership card (or scan via the Costco app if supported).
- Select payment method: insert or tap an accepted credit/debit card.
- Authorize the transaction; some banks place a temporary hold (often €100-€200 equivalent).
- Choose fuel grade and begin pumping.
- Receipt prints automatically or is available digitally via your account.
This authorization hold system is standard across fuel retailers, but Costco's higher temporary hold amounts have occasionally triggered customer complaints, particularly among debit card users.
Costco Anywhere Visa Card Benefits
The co-branded credit card offered by Costco in partnership with Citi is tailored for fuel purchases, which explains why it dominates usage at Costco gas stations.
| Category | Cash Back Rate | Annual Cap |
|---|---|---|
| Gas (Costco & other stations) | 4% | $7,000/year (then 1%) |
| Restaurants & travel | 3% | No cap |
| Costco purchases | 2% | No cap |
| All other purchases | 1% | No cap |
This fuel rewards structure makes the Costco Anywhere Visa one of the most competitive gas cards in North America, particularly for high-mileage drivers. According to a 2025 J.D. Power credit satisfaction study, it ranked in the top quartile for cashback value among warehouse retail cards.
Common Sources of Confusion
The consumer confusion trends around Costco gas policies stem from several overlapping factors, including legacy partnerships and regional differences.
- American Express legacy: Costco accepted AmEx until June 2016, leading to outdated assumptions.
- Cross-border differences: U.S. shoppers expect Visa everywhere, but Canada uses Mastercard.
- Mobile wallet limitations: Apple Pay or Google Pay only work if linked to an accepted card network.
- Debit hold amounts: Temporary holds can appear as double charges to inexperienced users.
- Membership requirement: Non-members cannot purchase fuel, unlike some competitors.
This policy inconsistency perception is amplified by social media posts and outdated blog content, which often fail to reflect current payment rules.
Historical Context of Costco Payment Policies
The payment network transition in 2016 marked a major shift in Costco's financial strategy. After a 16-year partnership with American Express, Costco switched to Visa in the U.S. and Mastercard in Canada, citing better fee structures and broader consumer adoption.
This strategic partnership shift resulted in immediate operational changes: within the first quarter, Costco reported a 6% increase in transaction volume at gas stations, attributed partly to Visa's wider acceptance among U.S. consumers. The move also aligned Costco with global payment trends favoring Visa's infrastructure.
Tips to Avoid Payment Issues
Consumers can minimize friction by understanding the best payment practices specific to Costco gas stations.
- Always carry a backup Visa or Mastercard depending on region.
- Use a credit card instead of debit to avoid large temporary holds.
- Check your card's foreign transaction compatibility when traveling.
- Link accepted cards to mobile wallets before arriving.
- Keep your Costco membership active and accessible.
This preparation strategy ensures a faster and smoother fueling experience, especially during peak hours when Costco gas stations are known for long queues.
