Start with your statement and the transaction details
The fastest way to find out who charged your card is to look at your credit card statement — online or on paper — and find the transaction in question. The merchant name appears next to the charge, along with the date and amount. That name is often abbreviated or shortened, which is why it may not match what you remember seeing at the register or online.
Open your card issuer's website or app and look for the transaction. Most issuers let you click on or tap the charge to see more detail: a longer merchant name, a category (like "Groceries" or "Gas"), and sometimes a phone number or website. This expanded view often clears up confusion when ready. A charge that shows as "AMZN" on your statement might display as "Amazon.com" with a full description when you dig deeper.
If you still do not recognize the merchant name, write it down exactly as it appears. You will need this for the next step.
Key Takeaways
- Your credit card statement or app shows the merchant name, and clicking the transaction usually reveals a longer version with more detail.
- Search the exact merchant name online to find their website, customer service number, or social media accounts.
- Call your card issuer's customer service line if you cannot identify the charge after searching — they can see the merchant's full details and sometimes the transaction location.
- If you did not make the charge, report it as unauthorized to your card issuer right away; they will investigate and may issue a temporary credit while they work.
- Recurring charges you forgot about are common — check your subscriptions and auto-pay settings across all your accounts.
Search the merchant name online to find contact information
Once you have the merchant name from your statement, search it on Google or another search engine. Most legitimate businesses have a website, a phone number, and customer service contact information within the first few results. If the charge is from a large retailer or well-known company, you will find their main customer service line quickly.
Look for a "Contact Us" page on their website. Many merchants also list a customer service phone number on their receipt or invoice, so if you kept the receipt from the purchase, check that first. Some smaller merchants or service providers may only have a social media page or email address, but those are still ways to reach them and ask about the charge.
If the search returns no results or only suspicious-looking websites, that is a warning sign. Proceed to the next step and contact your card issuer instead.
Call the merchant directly to ask about the charge
Once you have found the merchant's phone number or contact method, call or email them and describe the charge. Give them the exact date, amount, and how the transaction appears on your statement. Ask them to confirm whether the charge came from them and, if so, what product or service it was for.
Be ready to provide your card number (the last four digits are usually enough) or any order number that might appear on your statement. The merchant's customer service team can look up the transaction on their end and tell you what it was for. If you made the purchase but forgot about it, they can also explain what you bought and whether it is part of a subscription or recurring charge.
Keep notes of who you spoke with, the date and time, and what they told you. If the merchant confirms the charge is legitimate but you still want to dispute it, you will have this record for your card issuer.
Contact your card issuer if you cannot identify the charge
If you cannot find the merchant online, the merchant will not confirm the charge, or you are certain you did not authorize it, call the customer service number on the back of your credit card. Tell them the charge in question and that you do not recognize it.
Your card issuer has access to more detailed information about the transaction than you do. They can see the merchant's full legal name, the location where the charge was processed (if it was made in person), and sometimes additional codes that identify the business. They may be able to tell you when ready what the charge is for, or they can help you take the next step.
If you tell your issuer you did not make the charge, they will ask you a few questions to confirm. They may place a temporary hold on your account while they investigate, and they can issue a temporary credit to your account within a few days while the investigation is underway. The investigation itself usually takes 30 to 60 days.
Report the charge as unauthorized if you did not make it
If you are certain the charge is fraudulent — meaning someone used your card without your permission — tell your card issuer that you want to report it as unauthorized. Do this as soon as you notice it. The sooner you report, the sooner your issuer can investigate and the sooner you may receive a credit.
Your card issuer will ask you to confirm that you did not make the purchase and did not authorize anyone else to make it. They will then open a dispute investigation. During this time, your account may be frozen or your card may be cancelled and replaced. Your issuer will send you a new card with a new number, usually within 7 to 10 business days.
While the investigation is happening, you are not responsible for the fraudulent charge under federal law. Your card issuer must credit your account for the disputed amount, though they may do so temporarily at first while they finish investigating.
Check for subscriptions and recurring charges you may have forgotten
Before you assume a charge is fraudulent, check whether it might be a subscription or recurring payment you signed up for and then forgot about. Streaming services, software subscriptions, gym memberships, and app purchases often renew automatically every month or year. The merchant name on your statement might be shortened or use a company name you do not when ready recognize.
Go through your email inbox and search for confirmation emails from the merchant. Look for words like "subscription," "renewal," "auto-pay," or "recurring." Most subscription services send a confirmation email when you sign up and another one before each renewal. If you find a confirmation, you can usually click a link in the email to manage or cancel the subscription.
You can also log into your accounts on popular services and check their billing or subscription settings. Amazon, Apple, Google, and most streaming platforms let you see active subscriptions and cancel them directly from your account page. If you find a subscription you no longer want, cancel it. If you were charged for something you did not authorize, contact that service's customer support and ask for a refund.
Protect your card after you resolve the charge
Once you have identified the charge or reported it as fraudulent, take steps to prevent future unauthorized charges. If your card was compromised, your issuer will send you a new card with a new number. Destroy the old card by cutting it up or shredding it.
Review your other statements from the past few months to see if there are other suspicious charges. If you find more than one, tell your issuer — that is a sign of a larger problem. You may also want to check your credit report through AnnualCreditReport.com (the official free source) to see if anyone has opened accounts in your name.
Going forward, check your statement at least once a month. Many card issuers offer alerts that notify you by text or email when a charge is made, which can help you spot fraud faster. You can usually set these alerts in your card issuer's app or website.
Frequently Asked Questions
What if the merchant name on my statement is completely different from what I remember?
Merchants often use shortened or coded names on statements. Click the transaction in your card issuer's app to see the full merchant name and category. If that does not help, search the shortened name online — you may find that it is a known abbreviation for a company you recognize. If you still cannot figure it out, call your card issuer and they can tell you the full merchant details.
How long does it take for my card issuer to investigate a fraudulent charge?
The investigation typically takes 30 to 60 days. Your card issuer must issue a temporary credit within a few days of your report, so you should not be without the money for long. They will contact you when the investigation is complete and let you know the outcome.
Can I get my money back if I authorized the charge but now regret it?
That depends on the merchant and the reason. If you bought something and changed your mind, contact the merchant directly to ask about a return or refund — that is faster than disputing the charge with your card issuer. If the merchant refuses and you believe they violated the terms of the sale, you can file a dispute with your card issuer, but the outcome is not may provide.
What should I do if I find multiple charges from the same merchant I do not recognize?
Contact your card issuer right away. Multiple unauthorized charges from the same merchant suggest your card number may have been stolen or your account may have been compromised. Your issuer can cancel your card and investigate all the charges at once. They may also recommend that you monitor your credit report and consider placing a fraud alert with the credit bureaus.
Is it safe to call the phone number listed on my statement if I do not recognize the merchant?
It is safer to search the merchant name online and find their official website and phone number yourself, rather than calling a number that appears on your statement. Scammers sometimes create fake statements or use similar names to trick people into calling fraudulent numbers. Use an official source like Google or the company's website to find the real contact information.
