An unfamiliar charge on your credit card can be alarming, especially when the amount is small enough to overlook. Your priority is to stop further use of the account, report the transaction, and preserve your rights before a billing deadline passes.
Federal law protects U.S. cardholders against unauthorized credit card charges. Yet telling customer service about suspected fraud and formally disputing a billing error are not always the same step. Understanding the difference matters.
What to Do When You Spot a Suspicious Charge
Check the transaction, but don’t delay reporting
Some unfamiliar transactions are legitimate. A merchant may use its parent company’s name, a trial may have become a subscription, or a pending authorization may differ from the final charge. Check receipts and ask other authorized users if they recognize the purchase.
If you still cannot identify it, contact your issuer immediately. A small unauthorized credit card charge can be a test before a larger fraudulent purchase.
Contact the issuer through a trusted channel
Use the number on your card, a statement, or the official banking app. Explain which transaction you believe was unauthorized and request steps to prevent further misuse, including a replacement card if needed.
Record the representative’s name, the date, and your case number. Enable transaction alerts, check recent activity, and change your account password if you suspect compromised credentials. Never rely on a phone number supplied in an unexpected fraud-alert text.
Save the first signs of possible fraud
Imagine spotting a $14.95 online charge followed two days later by a $690 electronics purchase. Report both, even if the first was reversed. Screenshots showing the transaction dates, merchant names, and amounts can help establish a pattern of credit card fraud.
How Much Can You Be Required to Pay?
Under the Truth in Lending Act and Regulation Z, your liability for unauthorized use of a lost or stolen credit card is generally limited to $50 for charges made before you report it missing. Report the loss before fraudulent use occurs, and you owe nothing for later unauthorized charges. If only your account number was stolen and you retained the card, you generally have no liability for unauthorized use.
Many issuers voluntarily provide broader zero-liability protection. Review your cardholder agreement, but report suspicious transactions promptly regardless of the policy.
Authorization is not always straightforward. If you willingly allowed someone to use your card, a purchase exceeding your instructions may still be considered authorized. An unwanted subscription or a disagreement over delivered goods may also involve different rules. Describe the facts accurately rather than labeling every disagreement as fraud.
Why the 60-Day Billing Dispute Deadline Matters
To invoke the Fair Credit Billing Act’s formal billing-error process, send a written notice that the issuer receives within 60 days after sending the first statement showing the charge. The deadline is tied to the statement, not when you noticed the problem. Phone the issuer right away, but don’t assume that calling alone preserves your written-dispute rights.
Use the billing-inquiries address on your statement, not the payment address. Electronic notice can qualify if the issuer expressly accepts billing-error notices through its designated method. Otherwise, send a letter promptly and keep delivery evidence.
How to explain the disputed transaction
Include your name and account identification, transaction date, amount, and a clear reason for disputing the charge. Ask the issuer to investigate and correct the error. Attach copies of relevant supporting records and keep originals.
For example: “I dispute the $690 charge dated June 8 from ABC Electronics. I did not make or authorize the purchase, and my card remained in my possession.” Precise facts are more helpful than speculation about how someone obtained the card details.
What Happens During the Investigation?
After receiving a qualifying written billing-error notice, the issuer generally must acknowledge it within 30 days unless it resolves the matter sooner. It must complete the required investigation within two complete billing cycles, and no later than 90 days.
You may withhold the disputed amount and related finance charges while the matter is investigated, but must still pay undisputed charges when due. The issuer generally cannot report the properly disputed amount as delinquent because you withheld payment during that process. It may continue listing the charge on statements while identifying it as not currently payable.
If the issuer confirms an error, it must correct the account and related charges as applicable. If it denies the dispute, it must give a written explanation and identify what remains payable. You can request documentary evidence supporting its conclusion.
Build a Useful Record, Not Just a Long One
Keep the statement showing the charge, a copy of your written notice, proof it arrived, transaction screenshots, case numbers, and issuer replies. A short timeline of when you noticed, reported, and disputed the activity makes follow-up easier.
Don’t send passwords or complete card numbers in ordinary email. If the issuer requests an affidavit or police report, ask what it needs to establish. A creditor cannot automatically deny a billing-error claim solely because you declined one particular document, although reasonable cooperation matters.
If your complaint remains unresolved, escalate with the issuer and consider filing a complaint with the Consumer Financial Protection Bureau. If fraud suggests broader identity theft, visit IdentityTheft.gov and consider freezing your credit reports.

Frequently Asked Questions
Must I pay a suspicious charge while it is disputed?
With a qualifying billing-error dispute, you generally can withhold the disputed amount and related charges while the investigation is pending. Continue paying legitimate, undisputed balances on time.
Can I report credit card fraud after 60 days?
Yes. Report it immediately even if the formal written billing-error window has passed. Other unauthorized-use protections and issuer policies may still apply, although missing the deadline can affect your procedural rights.
What if the issuer says I authorized the payment?
Request its written reasoning and supporting documents. Compare that evidence with your records, identify inaccuracies, and ask for reconsideration. A CFPB complaint may be appropriate if the investigation appears inadequate.
Do debit cards have the same protections?
No. Debit cards are generally governed by different federal rules, and reporting delays can increase your potential liability. Seek debit-card-specific guidance immediately if the funds came directly from your bank account.
Protect the Account and Preserve Your Rights
Unauthorized credit card charges call for quick security action followed by careful documentation. Contact the issuer as soon as you discover suspicious activity, respect the written dispute deadline, and continue paying legitimate charges. These steps give you a stronger foundation for asserting your cardholder rights and resolving the problem.
