Mudflap customers, drivers, dispatchers, and fleet operators may need help with a fuel code, discounted price, linked payment method, unexpected charge, receipt, IFTA report, account login, Mudflap Fuel Card, or unresolved support issue. Mudflap provides a diesel-discount app for drivers and a separate Visa fleet card for qualifying businesses.

Quick Answer: Call Mudflap Customer Service at 1-888-885-3835 or email support@mudflapinc.com. Mudflap currently states that live support is available 24 hours a day, 7 days a week, 365 days a year by phone, email, text, or chat. For a new Mudflap Fuel Card application, call a card specialist at 1-888-388-3275.

How to Contact Mudflap Customer Service

Use the correct Mudflap support route: The Mudflap app lets drivers buy discounted fuel using a linked bank account, debit card, or credit card. The Mudflap Fuel Card is a separate business charge card for approved fleets. Tell support which product you use because payment holds, billing statements, disputes, card replacement, and account closure are handled differently.

Best Mudflap Support Route by Issue

  • Fuel code is not working: Call 1-888-885-3835 while you are still at the truck stop.
  • Discount is missing or incorrect: Save the Mudflap and truck-stop receipts, then contact support.
  • Unexpected Mudflap charge: Check the purchase history and emailed receipt, then report the date, amount, and location.
  • Pending authorization or reduced credit: Identify whether the app or Fuel Card was used and ask support to explain the hold and final amount.
  • Lost or stolen Fuel Card: Call 1-888-885-3835 immediately or report it through the Fleet Portal.
  • New Fuel Card application: Call 1-888-388-3275.
  • Login or password problem: Use password reset and confirm the account phone number and email are current.
  • Receipt or IFTA report: Check the Fuel Codes section of the app.
  • Close an account: Email support for an app account; use the Fleet Portal for a Fuel Card account.
  • Unresolved complaint: Follow a phone call with a documented email and request escalation.

Mudflap App and Mudflap Fuel Card: What Is the Difference?

Mudflap App

The Mudflap app can be used for diesel purchases by drivers of trucks, pickups, RVs, and other diesel-powered vehicles. A driver selects a participating stop, obtains a six-digit fuel code, presents it to the fuel desk, pumps fuel, and is charged through the payment method connected to the app.

Mudflap emails a receipt showing the discounted amount. The truck-stop receipt can show the pump or retail price, so compare the correct receipts before reporting a missing discount.

The app currently has no user fee for debit-card or ACH payments. Mudflap’s FAQ states that credit-card payments carry a 1.9% processing fee.

Mudflap Fuel Card

The Mudflap Fuel Card is a Visa business charge card for qualifying fleets. It is subject to application and credit approval and includes fleet controls, reporting, driver management, and fraud-prevention tools.

Mudflap says the card has no annual, monthly, per-card, subscription, or interest charges. Other fees, including returned-payment or late-payment fees, can apply under the card agreement. The card may be issued by Celtic Bank or Community Federal Savings Bank; check the back of the card and the account agreement for the applicable issuer.

Mudflap Fuel Code Is Not Working

Mudflap fuel codes are currently valid for 24 hours and can be canceled without a fee if plans change.

If a code does not work:

  1. Confirm that it was generated for the truck stop where you are fueling.
  2. Check that it has not expired or already been used.
  3. Show the six-digit code to the fuel desk and follow the location’s authorization instructions.
  4. Record the stop, pump, code, time, and error message.
  5. Call 1-888-885-3835 before leaving the location when possible.

Do not publish an active fuel code. It is intended for one-time use by the purchaser or designated driver.

Mudflap Charge, Pending Hold, or Payment Problem

Charges Through the Mudflap App

After a fuel code is used, Mudflap charges the linked payment method for the discounted transaction. Mudflap may preauthorize the payment method to confirm available funds or credit. If a primary payment method fails, a backup payment method saved to the account can be used.

Before reporting an incorrect charge, compare the emailed Mudflap receipt, the app transaction, the truck-stop receipt, and the posted or pending bank transaction. The truck-stop receipt may show the retail price, while the Mudflap receipt shows the discounted charge.

Mudflap Fuel Card Authorization Holds

A merchant can place an authorization hold based on the retail price before the Mudflap discount is applied. At some locations, the hold can exceed the final purchase amount because the total is not yet known.

The current card agreement states that it can take a couple of days for the hold to be removed after the final transaction and discount are processed. Contact Customer Service if a hold remains longer than expected or prevents necessary fueling.

Missing Mudflap Discount or Incorrect Fuel Price

If the expected discount is missing:

  1. Open the transaction in the app or Fleet Portal.
  2. Compare the location, fuel type, gallons, retail price, and final Mudflap amount.
  3. Save both the truck-stop and Mudflap receipts.
  4. Email support@mudflapinc.com or call 1-888-885-3835.
  5. Explain the price shown before fueling and the amount that posted.

For Fuel Card transactions, Mudflap directs customers to monitor the account dashboard and report a missing or inaccurate discount. Mudflap may request the receipt and apply an account credit after verifying an eligible purchase.

Mudflap Receipts and IFTA Reports

Mudflap automatically emails a detailed receipt after an app fuel purchase. A printable PDF is included, and receipt history is available in the Fuel Codes section. Customers can also request an IFTA-formatted report there.

If a receipt is missing, check the registered email address and spam folder, review the Fuel Codes section, and contact support with the purchase date, location, gallons, and amount.

Mudflap Fuel Card Help

For a new Fuel Card application, call 1-888-388-3275. Existing cardholders should generally use 1-888-885-3835 or the Mudflap Fleet Portal for declined purchases, spending controls, statements, payments, missing discounts, card replacement, or account closure.

Lost, Stolen, or Compromised Mudflap Fuel Card

Call 1-888-885-3835 immediately or report the card through the Fleet Portal. Do not wait for an unauthorized charge to post before reporting a missing card or suspicious activity.

Disputing a Mudflap Fuel Card Charge

The current Fuel Card agreement instructs businesses to first try to resolve a purchase dispute with the merchant. A charge that may qualify for a Visa dispute must be reported in writing through the Mudflap Portal within 60 days after it posts. Report suspected unauthorized use immediately rather than waiting for that deadline.

Mudflap Login, Password, and Account Security

Use the “forgot password” option when you cannot sign in. Mudflap uses the phone number or email on file to verify password resets, so outdated contact information can delay account recovery.

If an unfamiliar purchase or account change appears:

  1. Change the Mudflap password.
  2. Review payment methods, drivers, and recent transactions.
  3. Call 1-888-885-3835.
  4. Block or report a compromised Fuel Card through the Fleet Portal.
  5. Contact the bank or card issuer if a linked payment method may also be compromised.

Do not publish passwords, verification codes, bank information, card numbers, driver’s-license images, Social Security numbers, or EIN records.

How to Close a Mudflap Account

Mudflap’s Terms and Conditions state that an app account can be terminated by emailing support@mudflapinc.com.

A Fuel Card account has a separate process. The current card agreement requires a written termination request through the Mudflap Portal. Outstanding balances remain due, and issued cards must be returned or destroyed as instructed.

Before closing, download needed receipts and IFTA records, review pending transactions, resolve disputes, and request written confirmation.

How to Escalate a Mudflap Customer Service Complaint

  1. Contact 24-hour support: Call 1-888-885-3835 or use chat.
  2. Create a written record: Email support@mudflapinc.com with the date, location, transaction, and requested resolution.
  3. Provide documentation: Include receipts, screenshots, statement entries, fuel-code information, and prior support references. Hide complete financial account numbers.
  4. State the requested result: Ask for a corrected discount, hold explanation, card replacement, account correction, receipt, refund review, or closure confirmation.
  5. Request escalation: Ask for a supervisor or the appropriate payment or Fuel Card team when the first response does not resolve the issue.
  6. Follow the applicable financial dispute process: Unauthorized payment or Fuel Card transactions can have separate reporting requirements and deadlines.
