Start by checking your own transactions first

An unfamiliar charge on your credit card statement is usually one of four things: a transaction you made but don't remember, a charge from a merchant under a different business name than you expected, a duplicate charge from a legitimate merchant, or fraud. The fastest way to find out which is to look at your own records before contacting anyone.

Check your email for receipts or confirmation messages from the date the charge posted. Search your email inbox for the merchant name as it appears on your statement — it may be abbreviated or use a parent company name you don't recognize. Look at your browser history or bank app transaction history for that date. If you made an online purchase, log into that retailer's account and check your order history; the charge date may not match the order date if the merchant held the funds and released them later.

If you find a receipt and the amount matches, the charge is yours — you can stop here. If you find a receipt but the amount is different, that's a duplicate or overcharge, which you'll dispute with the merchant first (see below). If you find nothing, move to the next step.

Key Takeaways

  • Check your own email receipts and order history before assuming fraud, because many charges come from merchants whose names don't match what you remember.
  • Contact the merchant directly before disputing with your credit card company, because they can often reverse a charge or explain what it was within days.
  • Your credit card company has a legal window to investigate disputes — usually 30 to 60 days depending on the type of charge — and must give you a temporary credit while they investigate.
  • Merchants can resubmit a charge after you dispute it if they have proof you authorized it, so the dispute process may not be final.
  • If the charge is from a subscription service you forgot about, the merchant won't reverse it, but you can cancel the subscription to stop future charges.

Contact the merchant if you don't recognize the name

Many legitimate charges appear under a name that doesn't match the store or service you used. A charge from "STRIPE" or "SQUARE" means you bought something from a small business that uses that payment processor. A charge from "AMZN" is Amazon. A charge from a parent company name means you bought from a subsidiary. Call the merchant's customer service number — not a number from the charge itself, but one you find independently — and read them the exact charge amount and date.

If it's a legitimate charge you made, the merchant can explain what it was. If it's a duplicate, they can reverse it immediately in many cases. If it's a subscription you forgot about, they'll confirm that too. Get a confirmation number or reference for any action they take. This step resolves most "unfamiliar" charges within one phone call.

File a dispute with your credit card company if the merchant won't help

If you cannot reach the merchant, they deny your account exists, or they refuse to reverse a charge you believe is wrong, contact your credit card issuer. Call the number on the back of your card or log into your online account. Tell them you want to dispute the charge and explain why — that you don't recognize it, that the merchant says it's not theirs, or that it's a duplicate.

Your card issuer will open a dispute case and assign it a reference number. By law, they must investigate within 30 days for most charges, or 60 days for charges made outside the United States. During the investigation, they will usually place a temporary credit in your account for the disputed amount so you're not out the money while they look into it. Write down the case number and the date you filed.

The issuer will contact the merchant's bank and ask for proof that you authorized the charge. If the merchant can't provide proof, the dispute is resolved in your favor and the temporary credit becomes permanent. If the merchant provides a signed receipt or other authorization, the issuer may close the dispute against you — but you can still try to resolve it with the merchant directly.

Understand what happens if the merchant disputes your dispute

After you dispute a charge, the merchant's bank may ask them for documentation that you authorized it. If they provide a signed receipt, a recorded phone call, or a clear record of your account activity, they can resubmit the charge. This is called a chargeback reversal. If this happens, your temporary credit will be removed and the charge will reappear on your statement.

At that point, you have the option to dispute again, but the outcome depends on what proof the merchant has. If the charge is for a subscription service you genuinely forgot about, disputing won't help — you'll need to cancel the subscription instead to stop future charges. If the charge is fraudulent and you can prove you never authorized it, you may need to provide your card issuer with additional evidence, such as a police report or a statement that you were not in the location where the charge was made.

Report fraud to your card issuer and the FTC if you believe you're a victim

If the charge is fraudulent — meaning someone used your card number without your permission — tell your card issuer immediately. They will cancel your current card and issue a replacement. You are not liable for fraudulent charges under federal law, though your card issuer may require you to sign a statement saying you did not authorize the transaction.

You can also report the fraud to the Federal Trade Commission at IdentityTheft.gov. This creates an official record and may help if the fraud is part of a larger pattern. If you believe your card number was stolen, check your other statements and credit reports for additional unauthorized charges. You can request a free credit report from each of the three major bureaus — Equifax, Experian, and TransUnion — at AnnualCreditReport.com.

Know the difference between a dispute and a refund

A refund is when a merchant agrees the charge was wrong and returns your money. This is the fastest resolution and happens outside the dispute process. A dispute is when you tell your card issuer the charge is wrong and ask them to investigate. Disputes take longer but protect you if the merchant won't cooperate.

Always try to get a refund from the merchant first. If they refuse or you can't reach them, then file a dispute. Some merchants will refund you quickly to avoid a dispute on their record, because too many disputes can hurt their ability to accept credit cards. Others will only refund if you dispute, because that forces them to prove the charge was legitimate.

Protect yourself from future unrecognized charges

Review your credit card statement every month, even if you receive it electronically. Set a phone reminder or calendar alert. Many fraudulent charges are small amounts that go unnoticed for months, which makes them harder to dispute later. If you use your card for subscriptions, keep a list of which services charge you and when, so you can spot a duplicate or an unexpected renewal.

If you see a charge you don't recognize but aren't sure whether it's fraud, contact the merchant first before disputing. This approach resolves most cases faster and doesn't trigger a dispute on the merchant's record. Save receipts and confirmation emails for at least 60 days after any purchase, in case you need to prove you authorized a charge.

Frequently Asked Questions

How long does a credit card dispute take?

Your card issuer must investigate within 30 days for most charges, or 60 days for charges made outside the U.S. You'll usually get a temporary credit within 5 to 10 business days. The final outcome depends on whether the merchant can prove you authorized the charge.

Am I responsible for paying a fraudulent charge while the dispute is open?

No. Your card issuer must place a temporary credit in your account while they investigate, so you won't be charged interest or late fees on the disputed amount. If the dispute is resolved in your favor, the temporary credit becomes permanent.

What if the merchant says I authorized the charge but I didn't?

If you have proof you didn't authorize it — such as a statement that you were not in the location where the charge was made, or that the card was lost at the time — provide that to your card issuer. You may also file a police report for fraud, which strengthens your case.

Can a merchant charge me again after I dispute?

Yes. If the merchant provides proof you authorized the charge, they can resubmit it after your dispute is closed. This is called a chargeback reversal. If this happens, you can dispute again, but the outcome depends on what evidence the merchant has.

What should I do if I recognize the charge after I've already disputed it?

Contact your card issuer and ask to withdraw the dispute. Explain that you've confirmed the charge is legitimate. This prevents the merchant from having to respond to a dispute they don't deserve.
