Exxon Mobil Smart Card+ customers may need help with a credit-card payment, billing question, declined transaction, lost or stolen card, online account access, fuel discount, statement credit, fraud concern, application, or Exxon Mobil Rewards+ connection. The Exxon Mobil Smart Card+ is issued by Citibank, N.A., so credit-card billing and account issues should be directed to Citi’s Exxon Mobil Credit Card support rather than ordinary Exxon or Mobil station customer service.

What Is the Exxon Mobil Smart Card+?
The Exxon Mobil Smart Card+ is a private-label credit card issued by Citibank.
It can be used at participating Exxon and Mobil branded stations.
Unlike a general-purpose Visa or Mastercard, the Smart Card+ is designed primarily for purchases within the participating Exxon and Mobil network.
At participating locations, customers can use it for:
- Fuel at the pump
- Fuel purchased through the Exxon Mobil Rewards+ app
- Qualifying convenience-store purchases
- Car washes
The card is subject to credit approval.
Exxon Mobil Smart Card+ Fuel Savings
Current Smart Card+ fuel benefits include:
- 12 cents per gallon in savings on Exxon Supreme+ or Mobil Supreme+ premium gasoline
- 10 cents per gallon in savings on regular, mid-grade, and diesel fuel
The savings are normally applied as an immediate price reduction at the pump.
If the point-of-sale discount is unavailable for a qualifying transaction, Exxon Mobil states that the earned discount can instead appear as a statement credit within approximately one to two billing cycles.
Keep the fuel receipt when an expected discount does not appear.
Exxon Mobil Smart Card+ 5% In-Store Benefit
Smart Card+ customers can currently receive 5% back as a statement credit on the first $1,200 of qualifying non-fuel purchases each year at participating Exxon and Mobil stations.
Qualifying purchases can include:
- Snacks
- Drinks
- Car washes
- Other qualifying convenience-store merchandise
Excluded purchases include:
- Fuel
- Lottery tickets
- Money orders
- Gift cards
State restrictions may also apply.
The 5% benefit appears as a credit on the monthly Citi statement and can take one or two billing cycles to appear after a qualifying purchase.
Can Smart Card+ Savings Be Combined With Exxon Mobil Rewards+?
Yes.
Current Exxon Mobil guidance states that customers can stack Exxon Mobil Smart Card+ benefits with the Exxon Mobil Rewards+ loyalty program.
This means an enrolled Rewards+ member can receive the Smart Card+ per-gallon discount while also earning applicable Rewards+ points on qualifying transactions.
Current standard Rewards+ earning includes:
- 3 points per gallon on regular, mid-grade, or diesel fuel
- 6 points per gallon on qualifying premium fuel
- 2 points per dollar on qualifying convenience-store purchases and car washes
This is an important change from older Exxon Mobil materials that said Smart Card+ purchases did not earn Rewards+ points.
Use current Exxon Mobil Rewards+ terms rather than relying on older card brochures.
Exxon Mobil Smart Card+ Annual Fee
Exxon Mobil currently advertises the Smart Card+ with no annual fee.
However, a card with no annual fee can still have:
- Interest charges
- Late-payment fees
- Returned-payment fees
- Other charges permitted by the card agreement
Review the current Citi Terms & Conditions shown during the application process before applying because interest rates and account fees can change.
How to Apply for an Exxon Mobil Smart Card+
Applications are processed by Citibank.
Customers can apply online through the official Exxon Mobil Smart Card+ page or Citi’s Exxon Mobil card application.
Exxon Mobil states that applicants must meet current eligibility requirements and that approval is determined by Citibank.
If approved, Citi mails a physical card.
A customer applying through the Exxon Mobil Rewards+ app may also be able to add an approved digital card to the app and begin using it before the physical card arrives.
Do not provide Social Security numbers or other credit-application information through a website reached from an unsolicited email, text, advertisement, or search result that you cannot verify.
Start through ExxonMobilFuels.com or Citi’s official Exxon Mobil credit-card site.

Cardholders can sign in to:
- View the account balance
- Review transactions

Philadelphia, PA 19176-0605

The ordinary card customer-service number remains 1-800-344-4355 for billing and account servicing.
Lost or Stolen Exxon Mobil Credit Card
A lost or stolen card should be reported promptly to Citi.
Call:
Also review recent transactions for unauthorized activity.
Exxon Mobil currently advertises $0 fraud liability for unauthorized Smart Card+ charges, subject to the applicable account terms.
If the physical card was saved in the Exxon Mobil Rewards+ app or another supported digital account, review those payment settings as well.
Never publish the card number, security code, expiration date, account password, or fraud-case information in a public customer review.
What If the Fuel Discount Does Not Appear?
Smart Card+ savings are normally reflected as a reduced per-gallon price.
If a qualifying discount does not appear:
- Keep the fuel receipt.
- Confirm that the station participates in the Smart Card+ program.
- Confirm that the Smart Card+ was the payment method.
- Review the Citi statement.
- Allow the applicable one-to-two-billing-cycle period for a fallback statement credit.
- Contact Citi if the expected credit still does not appear.
The premium and other-fuel savings amounts can change, so check the current Smart Card+ page before relying on an older advertisement.
Smart Card+ Versus Exxon Mobil Rewards+
The Smart Card+ and Rewards+ programs serve different purposes.
Smart Card+ is a credit account issued by Citibank.
Exxon Mobil Rewards+ is a separate loyalty program operated for qualifying Exxon and Mobil station purchases.
A billing dispute, late payment, lost credit card, interest charge, or credit-account problem belongs with Citi.
A missing Rewards+ point balance, loyalty account, Frequent Filler status, or Rewards+ profile problem belongs with Exxon Mobil Rewards+ support.
Exxon Mobil Rewards+ currently lists:
also shown as 1-888-REWARD+.
Use the correct department so a loyalty-program question is not incorrectly sent to credit-card servicing.
Exxon Mobil Smart Card+ Versus Direct Debit+
Exxon Mobil also offers Direct Debit+, which is different from the Smart Card+ credit card.
Smart Card+ is a Citi-issued credit account.
Direct Debit+ is a separate payment product that connects to an eligible bank account.
Both products can offer fuel savings, but their:
- Application process
- Payment method
- Account servicing
- Terms
are different.
Check which product appears in your Exxon Mobil account before calling about an unfamiliar charge or payment.
Exxon Mobil Smart Card+ Mailing Addresses
For ordinary credit-card correspondence, Citi currently lists:
Exxon Mobil Credit Card
P.O. Box 6404
Sioux Falls, SD 57117
The payment address is different:
Exxon Mobil Credit Card
P.O. Box 70605
Philadelphia, PA 19176-0605
Do not send an ordinary payment to ExxonMobil corporate headquarters or to a local Exxon or Mobil station.
Who Issues the Exxon Mobil Smart Card+?
The Exxon Mobil Smart Card+ is issued by Citibank, N.A.
Exxon Mobil markets the card and provides the associated station discounts and Rewards+ integration, while Citi handles the credit account.
This distinction explains why:
- Credit approvals come from Citi.
- Monthly card statements come from Citi.
- Payments are made through Citi.
- Credit-account disputes are handled through Citi.
- Rewards+ loyalty issues may require Exxon Mobil instead.
ExxonMobil Corporate Headquarters
Exxon Mobil Corporation’s global headquarters is currently:
Exxon Mobil Corporation
22777 Springwoods Village Parkway
Spring, TX 77389-1425
The Houston-area campus serves as ExxonMobil’s global headquarters.
Corporate headquarters should not be used as the first contact for an Exxon Mobil Smart Card+ bill, payment, lost card, credit application, or account dispute.
Use Citi’s Exxon Mobil Credit Card support at 1-800-344-4355 for those issues.
How to Escalate an Exxon Mobil Card Complaint
If the first contact does not resolve the problem:
- Determine whether the problem involves the Citi credit account, an Exxon Mobil Rewards+ account, or a station transaction.
- Keep the monthly statement, fuel receipt, payment confirmation, and prior correspondence.
- Call Citi at 1-800-344-4355 for a Smart Card+ account issue.
- Explain the specific charge, payment, discount, or account problem.
- Ask the representative to document the account.
- Keep any case or dispute reference number.
- Ask for additional review when the initial response does not resolve the issue.
- For a missing Rewards+ benefit, separately contact Rewards+ support if Citi confirms the credit account is correct.
Do not dispute an ordinary gas-station merchandise or service complaint as a Citi account problem unless the issue actually involves the card transaction or billing.
