Guides How to Dispute Fraudulent Credit Card Charges

To the point Learn how to detect and dispute fraudulent credit card charges: set up alerts, monitor accounts regularly, and follow the proper steps to protect yourself.

Credit card fraud can happen to anyone at any time, regardless of how careful you are with your cards. While you likely won’t be financially responsible for fraudulent charges thanks to federal protections, detecting and disputing unauthorized transactions quickly is essential to minimize hassle and protect your credit.

This guide will walk you through how to effectively monitor your accounts, identify suspicious activity, and take the proper steps to dispute fraudulent charges when they occur.

How to Detect Fraudulent Credit Card Charges

The key to minimizing the impact of credit card fraud is early detection. Here are effective strategies to help you spot unauthorized transactions quickly:

Monitor Your Accounts Regularly

Check statements monthly: Review your credit card statements thoroughly when they arrive
Monitor transactions online: Don’t wait for your monthly statement—log into your account regularly to review recent activity
Check pending transactions: Catching fraud while charges are still pending can make the dispute process easier
Keep receipts: Save receipts for major purchases to compare against your statement

Set Up Account Alerts

Most credit card issuers offer customizable alerts that can notify you of account activity in real-time:

Transaction alerts: Get notified about all purchases or only those above a certain amount
“Card not present” alerts: Receive notifications when your card is used online or over the phone
International transaction alerts: Be informed when your card is used outside your home country
Unusual activity alerts: Many issuers use AI to detect and alert you about suspicious patterns

These alerts can be delivered via text message, email, or push notifications through your card issuer’s mobile app, giving you immediate awareness of potential fraud.

Know What to Look For

Common signs of credit card fraud include:

Unfamiliar merchant names: Charges from businesses you don’t recognize
Unusual locations: Transactions in cities or countries you haven’t visited
Multiple charges from the same merchant: Especially small “test” charges followed by larger ones
Round number purchases: Fraudsters often make purchases in even dollar amounts
Unexpected declined transactions: If your card is suddenly declined, it could mean someone has maxed out your credit line

Distinguishing Between Fraud and Billing Errors

Before reporting fraud, determine whether the unrecognized charge might be a simple error rather than malicious activity:

Search the merchant name: Many businesses operate under different names than what appears on statements—search online for the merchant name to see if it’s actually a legitimate purchase
Check with authorized users: If family members or others are authorized to use your account, verify they didn’t make the purchase
Look for recurring subscriptions: Annual renewals for services you signed up for long ago can be surprising
Identify parent companies: Some charges appear under a parent company name rather than the store where you shopped
Contact the merchant directly: For double charges or incorrect amounts, the merchant may be able to resolve the issue faster than a formal dispute

How to Dispute Fraudulent Credit Card Charges

If you’ve confirmed that a charge is unauthorized, follow these steps to dispute it effectively:

Step 1: Contact Your Credit Card Issuer Immediately

Call the number on the back of your card: This is the most direct way to report fraud
Explain the situation clearly: Identify which charges are fraudulent and confirm which are legitimate
Ask about next steps: The representative should explain the dispute process and timeline
Request a new card: Your issuer will typically cancel your compromised card and issue a new one with a different number
Update automatic payments: Make a list of recurring payments linked to your card that will need updating

Most major credit card issuers also allow you to dispute charges online or through their mobile apps. Look for a “dispute this charge” option when viewing your transactions.

Step 2: Follow Up in Writing

While calling is a good first step, the Fair Credit Billing Act (FCBA) provides the strongest protections when you submit your dispute in writing:

Send a formal dispute letter: Address it to your card issuer’s billing inquiries department, not the payment address
Include essential information: Your name, account number, and details of the disputed transaction(s)
Attach supporting documentation: Include copies (not originals) of any relevant receipts or correspondence
Be timely: Your letter must reach the issuer within 60 days of when the bill containing the error was mailed to you
Use certified mail: Request a return receipt so you have proof the issuer received your letter
Keep copies: Maintain a complete file of all correspondence

The Federal Trade Commission (FTC) offers a sample dispute letter you can use as a template.

Step 3: Monitor the Investigation

Once you’ve initiated a dispute, stay engaged in the process:

Track the timeline: By law, the issuer must acknowledge your written dispute within 30 days and resolve it within two billing cycles (not exceeding 90 days)
Check your statements: Verify that disputed charges are marked accordingly
Respond promptly: If the issuer requests additional information, provide it quickly
Document all communication: Keep notes of phone conversations, including representative names and dates

Your Rights During the Dispute Process

The Fair Credit Billing Act provides important protections while your dispute is being investigated:

You don’t have to pay the disputed amount: You can withhold payment on the specific charge in question while it’s under investigation
You must pay the undisputed portion: Continue making payments on the rest of your bill to avoid late fees
Your account remains active: The issuer cannot close or restrict your account during the investigation
No collection actions: The issuer cannot take steps to collect the disputed amount or report it as delinquent
No negative credit reporting: The issuer may note that you’re disputing a charge, but cannot report you as delinquent for that amount
Protection from retaliation: The issuer cannot discriminate against you for exercising your dispute rights

What Happens After the Investigation

The credit card issuer must provide a written explanation of their findings:

If the Issuer Rules in Your Favor

Credit to your account: The disputed amount will be permanently removed
Refund of related charges: Any interest or fees related to the disputed amount will be refunded
Written confirmation: You’ll receive documentation of the resolution

If the Issuer Rules Against You

Written explanation: The issuer must explain why they believe the charge is valid
Supporting documentation: You can request copies of documents the issuer used to make their determination
Payment timeline: The issuer must give you time to pay the disputed amount without additional penalties
Right to appeal: You can appeal the decision within the time period the issuer gives you for payment (or within 10 days of receiving their explanation, whichever is later)

If you disagree with the issuer’s findings, you can:

File a complaint with the Consumer Financial Protection Bureau (CFPB)
Contact your state’s attorney general or consumer protection office
Consider small claims court for significant amounts

Your Liability for Fraudulent Charges

Federal law limits your financial responsibility for unauthorized credit card charges:

Maximum liability of $50: Under the Fair Credit Billing Act, your liability for unauthorized charges is capped at $50
Zero liability policies: Most major credit card issuers go beyond the law and offer zero liability for fraudulent transactions
No liability for “card not present” transactions: You have no liability for unauthorized online or phone purchases
Timely reporting matters: Report suspected fraud as soon as possible to minimize complications

Preventing Future Credit Card Fraud

While you can’t completely eliminate the risk of credit card fraud, you can take steps to reduce your vulnerability:

Sign up for account alerts: Enable notifications for all transactions or those above a certain amount
Use virtual card numbers: Many issuers offer virtual card numbers for online shopping
Enable two-factor authentication: Add this extra security layer to your online account access
Regularly check your credit reports: Monitor for unauthorized accounts or inquiries
Be cautious with your card information: Only provide your card details on secure websites (look for “https” and a lock icon)
Inspect card readers: Check for skimming devices before inserting your card at ATMs or gas pumps
Use mobile payment options: Services like Apple Pay and Google Pay add an extra layer of security

Bottom Line

Credit card fraud is an unfortunate reality in today’s digital world, but you have strong protections under federal law. By monitoring your accounts regularly, setting up alerts, and knowing how to dispute unauthorized charges properly, you can minimize the impact of fraud on your finances and peace of mind.

Remember that timing is crucial—the sooner you identify and report fraudulent activity, the easier the resolution process will be. Make account monitoring a regular habit, just like checking your email or social media accounts, and you’ll be well-positioned to catch and address fraud quickly if it occurs.

Most importantly, don’t panic if you discover fraud on your account. The systems in place to protect consumers are robust, and with prompt action, you can resolve most issues with minimal hassle and financial impact.

Frequently Asked Questions

How quickly should I report fraudulent credit card charges?

You should report fraudulent charges as soon as you discover them. While the Fair Credit Billing Act gives you up to 60 days from the date the statement containing the error was mailed to dispute charges in writing, it’s best to act immediately. Most card issuers allow you to dispute charges online or by phone, which can freeze the disputed amount right away and prevent further unauthorized activity. The sooner you report fraud, the easier it typically is to resolve, and many issuers will expedite replacement cards if you report fraud promptly.

What information should I have ready when disputing a credit card charge?

When disputing a credit card charge, be prepared with the following information:

• Your credit card number and personal identification details
• The exact date and amount of the fraudulent transaction(s)
• The merchant name as it appears on your statement
• Any transaction reference numbers from your statement
• A clear explanation of why you believe the charge is fraudulent
• Copies of relevant receipts or correspondence if available
• Details of any attempts you’ve made to resolve the issue with the merchant
• A timeline of when you discovered the fraud

Having this information organized before contacting your card issuer will help stream line the dispute process and ensure all relevant details are captured in your case.

Can I dispute a charge if I authorized the purchase but am unhappy with the product or service?

This situation falls under a different category than fraud. If you authorized a purchase but are dissatisfied with what you received, you should first attempt to resolve the issue directly with the merchant. However, if the merchant refuses to address legitimate concerns, you may have rights under a different protection called a “chargeback for quality disputes.”

To qualify for this type of dispute:

• The purchase must have cost more than $50
• The purchase must have been made in your home state or within 100 miles of your billing address
• You must have made a good faith effort to resolve the issue with the merchant first

If these conditions are met, you can dispute the charge with your credit card issuer, explaining the quality issue and your attempts to resolve it. The process is similar to disputing fraud, but the burden of proof is higher, and you’ll need to document your efforts to work with the merchant.

Will disputing a charge affect my credit score?

Properly disputing a fraudulent charge should not negatively affect your credit score. During the investigation period, the credit card issuer cannot report the disputed amount as delinquent to the credit bureaus. If the dispute is resolved in your favor, the charge will be removed from your account as if it never happened, with no impact on your credit score.

However, if you withhold payment on legitimate charges or on the undisputed portion of your bill during the investigation, those amounts could be reported as late payments, which would affect your credit score. That’s why it’s important to continue paying the undisputed portion of your bill on time while the investigation is in progress.

Additionally, if a card is compromised and needs to be replaced, the new card will typically maintain the same account history as the old one, so the account age (which positively affects your credit score) remains intact.

What if the fraudulent charge is from a subscription or recurring payment?

Fraudulent recurring charges require special handling. In addition to disputing the unauthorized charges with your credit card issuer, take these extra steps:

1. Contact the merchant directly to cancel the subscription or recurring payment
2. Request written confirmation of the cancellation
3. Monitor your account closely for additional charges
4. If new charges appear after cancellation, dispute them immediately
5. Consider placing a block on that specific merchant through your card issuer

In cases where you cannot identify or contact the merchant, your card issuer can help block future charges from that vendor. This is particularly important with fraudulent subscriptions, as simply disputing the current charge won’t prevent future unauthorized charges from appearing. In extreme cases where unauthorized recurring charges continue despite your efforts, you may need to have your card reissued with a new number.

How long does it take to resolve a credit card dispute?

By law, credit card issuers must acknowledge your written dispute within 30 days and resolve it within two billing cycles (not exceeding 90 days) after receiving your dispute letter. However, many disputes are resolved much faster, especially when reported promptly.

The timeline typically follows this pattern:

• Initial acknowledgment: 1-5 business days
• Temporary credit to your account: Often within 10 business days
• Investigation period: 30-90 days
• Final resolution: Within 90 days of receiving your dispute

Simple cases of obvious fraud are often resolved quickly, sometimes in just a few days. More complex disputes, especially those involving merchants who contest the chargeback, may take the full 90 days. During this time, you’re not required to pay the disputed amount, and the issuer cannot charge interest or late fees on that portion of your bill.
