Seeing a charge you don't recognize can make your stomach drop fast. One minute you're checking your account balance. The next, you're wondering whether your card information has been stolen.

Unfortunately, unauthorized charges are more common than many people realize. According to the Federal Trade Commission, consumers reported billions of dollars lost to fraud in recent years, with credit card fraud remaining one of the most frequent issues. The good news? Acting quickly can dramatically improve your chances of recovering your money and limiting further damage.
At community banks like ours, we've helped customers through these stressful situations many times. And while every case is different, the process for disputing unauthorized debit card charges and credit card fraud follows a few important steps.
Here's what you should do if you spot a suspicious transaction on your account.
What Counts as an Unauthorized Charge?
An unauthorized charge is any transaction made without your permission or knowledge. That could include:
- Fraudulent online purchases
- Stolen card transactions
- Duplicate charges
- Charges from merchants you've never heard of
- Recurring subscriptions you never approved
- Card information compromised through data breaches
Sometimes the issue is fraud. Other times, it's a billing error or forgotten subscription. Either way, it's important not to ignore it.
Step 1: Review the Transaction Carefully
Before filing a dispute, take a close look at the charge details.
Many merchants use parent company names or payment processors that look unfamiliar on your statement. A quick online search may reveal the business is legitimate after all.
You should also:
- Check with family members or authorized users
- Review recent receipts and online orders
- Look for pending transactions that may later update with clearer descriptions
If the transaction still doesn't look right, move quickly.
Step 2: Lock or Freeze Your Card Immediately
If you suspect fraud, your first priority is preventing additional charges.
Most banks and credit card companies allow you to temporarily lock your card through online banking or a mobile app. If that option isn't available, call your financial institution right away.
Taking immediate action can:
- Stop additional unauthorized transactions
- Reduce your financial exposure
- Speed up the fraud investigation process
If your physical card was lost or stolen, request a replacement immediately.
Step 3: Contact Your Bank or Credit Card Company
The next step is formally reporting the unauthorized charge.
For the fastest response, contact your bank or card issuer directly using the phone number listed on:
- The back of your card
- Your banking app
- Your official account statement
Avoid searching random phone numbers online, especially during stressful moments. Fraudsters sometimes create fake support numbers to target consumers.
When you contact your financial institution, be prepared to provide:
- The date and amount of the suspicious charge
- The merchant name
- Details about why you believe the transaction is unauthorized
- Confirmation of whether your card is still in your possession
Step 4: Understand Your Rights Under Federal Law
Consumers have important protections when reporting fraudulent charges.
For credit cards, the Consumer Financial Protection Bureau explains that your liability for unauthorized charges is generally limited to $50 under federal law — and many card issuers offer zero-liability policies.
Debit cards work differently. Your liability often depends on how quickly you report the fraud.
According to the Federal Trade Commission:
- Report before unauthorized charges occur: $0 liability
- Report within 2 business days: up to $50 liability
- Report after 2 business days: liability can increase significantly
That's why timing matters so much with debit card fraud.
Step 5: File a Formal Dispute
Your bank or card issuer may ask you to:
- Submit a written dispute
- Complete a fraud affidavit
- Verify recent transactions
- Provide supporting documentation
In many cases, you can complete this process online through your banking portal.
Be as detailed and accurate as possible. Clear documentation helps investigators resolve claims faster.
Helpful records include:
- Screenshots of suspicious charges
- Emails or receipts
- Notes from conversations with merchants
- Copies of police reports if applicable
Step 6: Monitor Your Account Closely
Even after filing a dispute, keep a close eye on your accounts.
Fraudsters sometimes test stolen card numbers with small purchases before making larger transactions later.
Watch for:
- Tiny "test" charges
- Additional suspicious purchases
- Login alerts or password reset emails
- Unauthorized transfers or withdrawals
This is also a smart time to:
- Change your online banking password
- Update passwords on shopping sites
- Enable multi-factor authentication
- Review linked payment apps
Step 7: Follow Up Until the Case Is Resolved
Fraud investigations can take time. Some disputes are resolved within days. Others may take several billing cycles depending on the complexity of the case.
During the process:
- Save all correspondence
- Respond promptly to requests for information
- Check your account for provisional credits
- Review final investigation results carefully
If you disagree with the outcome, you may have the right to appeal or provide additional evidence.
Debit Card vs. Credit Card Fraud: Why the Difference Matters
One reason many financial experts recommend using credit cards for online purchases is consumer protection.
Credit cards generally offer:
- Stronger fraud protections
- Easier dispute processes
- Less direct impact on your checking account balance
With debit cards, fraudulent charges can temporarily remove actual cash from your account while the investigation takes place.
That doesn't mean debit cards are unsafe. It simply means reporting suspicious activity immediately is especially important.
Tips to Help Prevent Unauthorized Charges
While no system is perfect, a few proactive habits can greatly reduce your risk.
Use Account Alerts
Set up transaction alerts through your bank so you're notified immediately about purchases, withdrawals, or login attempts.
Avoid Public Wi-Fi for Banking
Public networks can expose sensitive financial information if they're unsecured.
Review Statements Frequently
Many people only notice fraud weeks later because they rarely review account activity. A quick weekly check can make a huge difference.
Use Digital Wallets When Possible
Payment methods like Apple Pay or Google Pay add additional layers of encryption and tokenization for security.
Be Careful With Phishing Scams
Fraudsters often impersonate banks, delivery companies, or government agencies to steal account information. Never click suspicious links or provide personal information through unsolicited messages.
The FDIC Consumer News Center regularly shares updates and tips about current fraud scams targeting consumers.
When in Doubt, Reach Out Quickly
Unauthorized charges can feel overwhelming. Frustrating, too. But fast action matters more than perfection.
At community banks, we understand there's a real person behind every account. A family budget. A retirement plan. A small business trying to stay on track. That's why fraud prevention and customer support matter so much to us.
If something doesn't look right on your account, trust your instincts and contact your financial institution immediately. The sooner you report suspicious activity, the better your chances of protecting your money and restoring peace of mind.
