Start with your card statement and transaction history

The fastest way to find out who charged your card is to look at the exact amount and date on your statement, then search for that merchant name online. Your credit card issuer — Visa, Mastercard, American Express, Discover — shows the merchant name as it appears in their system, which is often shortened or uses a business code you won't recognize at first glance. A charge that reads "AMZN MKTP US" is Amazon Marketplace. "ADOBE *MONTHLY" is an Adobe subscription. Search the exact text from your statement in Google, and you'll usually find what the charge is within seconds.

If the merchant name is still unclear, log into your credit card account online or through the issuer's app and look for a transaction details page. Most issuers let you click on individual charges to see more information — sometimes a full merchant name, a phone number, or a website. Chase, Capital One, American Express, and Discover all show expanded details this way. The date and amount together are your strongest clues, because they narrow the search to a specific day and let you remember what you were doing at that time.

Key Takeaways

  • Search the exact merchant name from your statement in Google first — most unknown charges are recognizable once you see the full business name.
  • Log into your card issuer's website or app to view expanded transaction details, which often include a phone number or website for the merchant.
  • If you still can't identify the charge, call the merchant's customer service number directly using contact information you find online, not a number from your statement.
  • Contact your card issuer to dispute the charge if you don't recognize the merchant after searching, and ask them to reverse it while they investigate.
  • Check for recurring charges by looking at your last three to six months of statements, because many unknown charges are subscriptions you forgot about.

Check for subscriptions and recurring charges

Many people discover unknown charges are subscriptions they signed up for and forgot about — free trials that converted to paid, apps that charge monthly, or services bundled with other purchases. Look back through your last three to six months of statements and see if the same merchant name appears on the same day each month. If it does, you likely have an active subscription.

Search the merchant name plus the word "cancel" or "unsubscribe" to find instructions for stopping the charge. Most subscription services have a cancellation page in their account settings. If you can't find how to cancel, call their customer service line and ask them to stop billing your card. Keep the confirmation number they give you. This step matters because it stops future charges while you decide whether to dispute the past ones.

Call the merchant directly to ask about the charge

Once you've found the merchant's name, search for their official customer service phone number on their website — not on your statement, because scammers sometimes include fake numbers there. Call and describe the charge: the date, the amount, and what you were doing around that time. The merchant's customer service team can tell you exactly what you were charged for and why.

Be ready to provide your name, the last four digits of your card, and the transaction date. They may ask for your account number with them, if you have one. Write down the name of the person you spoke with, the time you called, and what they told you. If they confirm the charge is legitimate but you don't remember authorizing it, ask them to explain what triggered the charge — sometimes a charge appears weeks after you interact with a website or app.

Dispute the charge with your card issuer if you don't recognize it

If you've searched for the merchant, looked at your transaction details, and still don't recognize the charge, contact your credit card issuer and tell them you don't recognize it. You can do this by calling the number on the back of your card, logging into your account online, or using the issuer's mobile app. Most issuers have a "dispute" or "report unauthorized" button next to each transaction.

When you report the charge, the issuer will typically reverse it temporarily while they investigate — meaning the money goes back to your account within a few days. The investigation usually takes 30 to 60 days. During that time, the issuer contacts the merchant to ask whether the charge was authorized. If the merchant can't prove you authorized it, the reversal becomes permanent and you keep the money. If the merchant provides proof of authorization, the issuer will charge your card again and explain why.

Watch for common merchant name formats that hide the real business

Merchants often use shortened names, codes, or parent company names on credit card statements, which makes them hard to recognize. "STRIPE" might be a payment processor, not the actual merchant — the real business name appears only in the full transaction details. "PAYPAL *" means someone charged you through PayPal, but you need to log into PayPal to see who. "GOOGLE *PLAY" is the Google Play Store, and you'll need to check your Google account purchase history to see what app or game you bought.

If the merchant name includes a location code like "AMZN MKTP US" or "UBER *TRIP", that's the company's internal code for the country or service type. Search the base name — "AMZN" or "UBER" — plus the amount and date, and you'll usually find what you're looking for. If you see a charge from a company you've never heard of, search the exact name plus "scam" or "fraud" to see if other people have reported it as unauthorized.

Check your email for order confirmations and receipts

Search your email inbox for the merchant name or the amount of the charge. Most online purchases send a confirmation email within minutes, and that email usually includes an order number, what you bought, and a customer service contact. If you find a confirmation email you don't remember receiving, you may have an account with that merchant that you forgot about. If you don't find any email, the charge may be fraudulent.

Check your spam and promotions folders too — some confirmation emails get filtered away. If you still find nothing after searching your email, that's a sign to contact your card issuer and report the charge as unauthorized. The absence of a confirmation email doesn't prove fraud on its own, but combined with not recognizing the merchant name, it strengthens your case for a dispute.

Report fraud to your card issuer and the FTC if the charge is unauthorized

If you've done all the above steps and you're certain you didn't authorize the charge, contact your card issuer when ready and report it as fraud or unauthorized. Most issuers let you do this online, by phone, or through their app. They will reverse the charge and send you a new card with a new number. The old card will be closed to prevent further unauthorized charges.

You can also report the fraud to the Federal Trade Commission at ReportFraud.ftc.gov. The FTC doesn't investigate individual cases, but they track fraud patterns and use the reports to identify scams affecting large numbers of people. If your card number was compromised, the FTC's report helps them warn other consumers and businesses. Keep copies of all your dispute paperwork and correspondence with your issuer, because you may need it if the merchant contests the reversal.

Frequently Asked Questions

How long does it take to get my money back after I dispute a charge?

Your card issuer usually reverses the charge within 3 to 5 business days, so you see the money back in your account quickly. The full investigation takes 30 to 60 days. If the merchant doesn't respond or can't prove you authorized the charge, the reversal stays permanent. If they provide proof, the issuer will charge your card again and send you a written explanation.

What if the merchant says I authorized the charge but I don't remember it?

You can still dispute it. Authorization doesn't have to be a signature — it can be a checkbox you clicked, a phone call, or even a free trial you started. If you don't remember authorizing it, tell your issuer that. They'll ask the merchant for proof of authorization, and if the merchant only has a checkbox or a vague record, your dispute may succeed. Keep any emails or screenshots you have that show you didn't intend to be charged.

Can I get my money back if I authorized the charge but changed my mind?

That depends on the merchant's refund policy, not your card issuer. If you bought something and want to return it, contact the merchant directly and ask for a refund. If the merchant refuses and their policy allows it, you can dispute the charge with your issuer, but the issuer may side with the merchant if you clearly authorized the purchase. Disputes work best for unauthorized charges, not buyer's remorse.

What should I do if I find multiple unknown charges from the same merchant?

Report all of them to your card issuer at once. Multiple charges from the same merchant suggest either a billing error or fraud. Your issuer will investigate all of them together, which can speed up the process. Ask your issuer whether you should cancel or freeze your card to prevent more charges while they investigate.

Is it safe to call a phone number from my credit card statement?

No. Scammers sometimes include fake customer service numbers on statements or in emails. Always search for the merchant's official website and call the number listed there. If you're unsure whether a number is real, hang up and call your card issuer instead — they can tell you whether the charge is legitimate and provide you with the merchant's real contact information.
