What to check first (before you act)

Goal and timeline

What is your primary goal? Is it to recover lost funds, prevent future fraud, or both? Your timeline for resolving this will depend on how quickly you can gather information and report it. Generally, acting fast is crucial.

Current cash flow

Before disputing a charge, ensure you have enough available credit or cash to cover your essential expenses. If the unauthorized charge has reduced your available credit significantly, you might need to adjust your spending temporarily.

Emergency fund or safety buffer

An emergency fund can provide peace of mind during a fraud investigation. If you have a buffer, you won’t have to worry about immediate financial strain while your credit card company resolves the issue.

Debt and interest rates

Understand the terms of your credit card agreement. While you typically won’t be liable for unauthorized charges, be aware of how any legitimate charges are being handled regarding interest if you have a balance.

Credit impact

Unauthorized charges, if not promptly disputed and resolved, could potentially impact your credit score if they lead to missed payments on legitimate balances or are incorrectly reported. However, disputing fraudulent activity itself should not harm your credit.

Step-by-step (simple workflow)

1. Review your credit card statements

What to do: Carefully examine every transaction listed on your current and past credit card statements.
What “good” looks like: You have identified all charges you authorized and can account for them.
Common mistake: Only checking the most recent statement.
How to avoid it: Review at least the last two to three months of statements, as fraudulent charges can sometimes be small or appear infrequently.

2. Identify unfamiliar transactions

What to do: Make a list of any merchants, amounts, or dates that don’t match your memory or records.
What “good” looks like: You have a clear list of all potential unauthorized charges.
Common mistake: Assuming a small charge is insignificant.
How to avoid it: Even small, recurring charges can indicate a larger problem or a subscription you don’t remember signing up for. Investigate all unknowns.

3. Research suspicious merchant names

What to do: If a merchant name is vague or unfamiliar, search online for it. Sometimes, the name on the statement differs from the actual business name.
What “good” looks like: You can confirm whether the transaction belongs to a legitimate business you’ve used, even if the name is slightly different.
Common mistake: Giving up if the merchant name is confusing.
How to avoid it: Use search engines to look for common variations of the merchant name or the associated phone number if available on the statement.

4. Check for recurring subscriptions

What to do: See if the unfamiliar charge is part of a recurring subscription or free trial that you may have forgotten about.
What “good” looks like: You’ve distinguished between actual fraud and forgotten recurring payments.
Common mistake: Immediately flagging a forgotten subscription as fraud.
How to avoid it: If you find a forgotten subscription, contact the merchant first to cancel it and request a refund, if applicable, before involving your credit card company.

5. Contact your credit card issuer

What to do: Call the customer service number on the back of your credit card as soon as possible.
What “good” looks like: You have spoken with a representative and initiated the dispute process.
Common mistake: Waiting too long to report the issue.
How to avoid it: Most credit card companies have time limits for reporting fraud, so act promptly.

6. Provide transaction details

What to do: Give the representative all the information you gathered about the unauthorized charges.
What “good” looks like: You have clearly communicated the specifics of each disputed transaction.
Common mistake: Not having enough information.
How to avoid it: Have your account number, the exact transaction details (date, amount, merchant), and any research you’ve done readily available.

7. Understand the dispute process

What to do: Ask your credit card issuer about their specific fraud investigation and dispute resolution process.
What “good” looks like: You understand the timeline, what to expect, and what information you might need to provide.
Common mistake: Not knowing your rights.
How to avoid it: Familiarize yourself with consumer protection laws like the Fair Credit Billing Act, which limits your liability for unauthorized charges.

8. Secure your account

What to do: Ask your credit card issuer to cancel your current card and issue a new one with a different number.
What “good” looks like: Your compromised card is no longer active and a new, secure card is on its way.
Common mistake: Not replacing the compromised card.
How to avoid it: If your card number was stolen, it’s essential to prevent further unauthorized use by getting a new card.

9. Monitor your credit reports

What to do: After reporting the fraud, check your credit reports from Equifax, Experian, and TransUnion for any other suspicious activity.
What “good” looks like: Your credit reports are free of any new fraudulent accounts or inquiries.
Common mistake: Forgetting to check credit reports.
How to avoid it: You can get free copies of your credit reports annually from each of the three major bureaus.

Common mistakes (and what happens if you ignore them)

Mistake	What it causes	Fix
Waiting too long to report	Increased risk of further fraud; potential denial of dispute; missed deadlines for protection.	Contact your credit card issuer immediately upon noticing an unauthorized charge.
Ignoring small charges	Small charges can be a test to see if an account is active, leading to larger fraudulent transactions later.	Treat every unrecognized charge, no matter how small, with suspicion and investigate it.
Not cancelling and replacing the card	The compromised card number can continue to be used for fraudulent purchases.	Always request a new card with a new number after reporting a compromise or unauthorized transaction.
Not understanding consumer rights	You might not get the full protection you’re entitled to under federal law.	Familiarize yourself with the Fair Credit Billing Act and your credit card issuer’s fraud policies.
Assuming the issuer will automatically fix it	The issuer needs your active participation to investigate and resolve the dispute.	Proactively provide all requested information and follow up on your dispute.
Not securing other financial accounts	If one account is compromised, others might be at risk if you use similar passwords or information.	Review and secure all your financial accounts, change passwords, and enable two-factor authentication where available.
Relying solely on credit monitoring	Credit monitoring alerts you to activity but doesn’t stop it; you still need to act.	Use credit monitoring as a tool, but don’t neglect your own regular statement reviews and prompt action.
Not keeping records of communication	Lack of documentation can hinder dispute resolution if questions arise later.	Keep copies of all correspondence, note dates and times of calls, and record the names of representatives you speak with.
Not checking for forgotten subscriptions	You continue to be charged for services you no longer want or need, masking potential fraud.	Regularly review your statements for recurring charges and cancel unwanted subscriptions promptly.
Failing to monitor credit reports	Other fraudulent accounts or inquiries may go unnoticed, impacting your credit score.	Obtain and review your credit reports from all three bureaus periodically.

Decision rules (simple if/then)

• If a transaction appears on your statement that you don’t recognize, then contact your credit card issuer immediately because prompt reporting is key to fraud protection.
• If the merchant name is vague or unfamiliar, then search online for it because it might be a different operating name for a legitimate business.
• If you discover a forgotten subscription, then contact the merchant first to cancel and request a refund because this is often easier than disputing it as fraud.
• If your credit card issuer confirms a fraudulent charge, then they will likely issue a new card number because this prevents further unauthorized use.
• If you are unsure about a transaction, then err on the side of caution and investigate it because it’s better to be safe than sorry.
• If your credit card company asks for more information during a dispute, then provide it promptly because delays can hinder the investigation.
• If you notice a pattern of small, recurring charges from the same merchant, then investigate it thoroughly because it could be a sign of ongoing unauthorized activity.
• If you have a zero-liability policy on your credit card, then you are generally not responsible for unauthorized charges because most major issuers offer this protection.
• If you suspect your identity has been compromised beyond just a credit card number, then consider placing a fraud alert on your credit reports because this adds an extra layer of protection.
• If you successfully dispute a charge, then ensure the credit appears on your statement and that no interest is charged on the disputed amount because the resolution should be complete.
• If you encounter resistance from your credit card issuer, then calmly reiterate your case and ask to speak to a supervisor because persistence can be helpful.
• If you see a charge from a location you haven’t visited, then this is a strong indicator of unauthorized use because it’s unlikely you made a purchase there.

FAQ

Q: How long do I have to report an unauthorized charge?

A: While policies vary, it’s best to report it as soon as you notice it. Many credit card companies have a time limit, often within 60 days of the statement date, to dispute a charge.

Q: Will reporting fraud hurt my credit score?

A: No, disputing fraudulent charges and having them removed should not negatively impact your credit score. In fact, not reporting it could lead to issues if it’s not resolved.

Q: What if the charge is very small? Should I still report it?

A: Yes, even small charges should be investigated. They could be a test run by fraudsters or a forgotten subscription that you want to cancel.

Q: What happens after I dispute a charge?

A: Your credit card issuer will typically launch an investigation. They may issue a provisional credit while they investigate, and you’ll be asked to provide documentation.

Q: Can I get my money back if I paid the bill with the unauthorized charge on it?

A: If you paid the bill and the charge was fraudulent, your credit card issuer will investigate and refund you for the unauthorized amount if the dispute is resolved in your favor.

A: It’s possible someone else used your card details with a legitimate merchant. Contact the merchant first to see if they have any information or if it was a mistake. If not, proceed with disputing it with your card issuer.

Q: How can I prevent future unauthorized charges?

A: Monitor your statements regularly, use strong, unique passwords for online accounts, enable two-factor authentication, and be cautious about sharing your credit card information online or over the phone.
