How to Contact Sunoco Customer Service

Choose the Correct Sunoco Support Route

Station Feedback and Store Complaints

For complaints about a specific Sunoco station, start with the station manager or operator when possible. Many Sunoco locations are independently operated, so local management may be the fastest way to resolve issues involving employees, restrooms, receipts, store conditions, pricing, or product availability.

If the location does not resolve the issue, call 1-800-786-6261 or use Sunoco’s official contact form. Sunoco’s form includes topics such as station feedback, transaction disputes, Mobile App/Go Rewards loyalty, other loyalty programs, and other customer issues.

Fuel, Pump, and Gasoline Issues

For fuel-quality concerns, wrong fuel, pump malfunction, missing receipt, or gas-price issues, write down the station address, pump number, fuel grade, gallons purchased, date, time, and payment method. Keep your receipt and any vehicle repair documentation if you believe the fuel caused a vehicle problem.

Transaction Disputes and Incorrect Charges

For incorrect charges, duplicate charges, pending authorizations, missing refunds, or payment disputes, compare your receipt with your bank or credit card statement. Contact the station first if the issue appears tied to a local register or pump, then contact Sunoco customer service if it remains unresolved.

Sunoco Pay and Mobile App Support

For Sunoco Pay, mobile payment, linked checking account, app login, digital receipt, or Go Rewards issues, contact Sunoco Pay support at 1-800-337-9897. If you believe your Sunoco Pay account or payment device was used without permission, call 1-800-337-9780 as soon as possible.

Sunoco Credit Card Questions

Sunoco’s consumer credit-card program may change over time. If you have an existing Sunoco credit card, use the phone number shown on the back of your card, your billing statement, or the official Sunoco credit-card payment portal. Do not enter credit-card details into unofficial websites.

Sunoco Fleet Card Questions

For Sunoco Business Fleet Card or Sunoco Fleet Universal Card questions, call 1-800-950-6124 or use the official Sunoco Fleet Cards website.
