An unfamiliar transaction on a credit card statement may be fraud, a merchant using a different billing name, a delayed transaction, or a purchase made by another authorized cardholder. Act promptly, but first check the details so you can report the problem accurately.
1. Check the transaction
Compare the amount and date with recent receipts, subscriptions, delivery services, travel bookings, and purchases by authorized users. Some merchants process payments under a parent-company name. If you still do not recognize it, treat the charge as potentially unauthorized.
2. Contact your card issuer using a trusted channel
Use the phone number on the back of the card or the issuer’s official app or website—not a link in an unexpected text or email. Report the charge, ask whether the card should be locked or replaced, and follow the issuer’s fraud-reporting process. Change the password for your online card account if you suspect login compromise, and enable multifactor authentication where available.
3. Keep a clear record
- Write down the transaction date, amount, merchant descriptor, and case number.
- Save relevant statements, receipts, secure messages, and copies of any letters.
- Ask the issuer whether a written billing-error notice is required and where to send it.
- Review subsequent statements for additional unfamiliar transactions.
4. Understand disputes versus fraud reports
A charge you made but believe is incorrect—such as a duplicate charge or a service not delivered—may follow a different dispute process from a transaction you never authorized. Explain the facts accurately and provide supporting documentation. Do not claim fraud simply because you regret a purchase or disagree with a merchant’s policy.
5. Watch deadlines and follow up
Credit-card billing-error protections can depend on the type of problem and when you notify the issuer. Check your card agreement and the official consumer guidance promptly rather than waiting for several statements. Keep paying the undisputed portion of your bill as required, and ask the issuer how the amount under investigation should be handled.
