Have you ever opened your credit card statement and felt your stomach drop at the sight of an unauthorised charge? Maybe it is a random $49.99 from some site you have never visited or a sneaky subscription that slipped through. Your mind races. Is it fraud? Did someone steal your card details? Or did you simply forget about that one click?
You are definitely not alone. Millions of people deal with unauthorised charges on credit card statements every single year. The good news is that credit card companies have strong protections in place, and you can usually fix it without losing a penny.

What Are Unauthorised Charges on Your Credit Card and Why Do They Happen?
Unauthorised charges on credit card statements are any transactions you did not approve. They pop up because someone used your card number without permission.
It could be a hacker who grabbed your details from a data breach, a skimmer at a dodgy ATM, or even a family member who borrowed the card and forgot to tell you. Sometimes it is a free trial that quietly turned into a paid subscription you never meant to keep.
These charges do not always scream “fraud” at first glance. The description might say something vague like “AMZ*” or just a company name you do not recognise.
Banks keep the wording short to fit the statement, which makes it even more confusing. But the key point is this: you have rights, and acting fast is what matters most.
Now, let us dive into the common reasons these show up so you can spot patterns in your own statement.
Common Causes of Unauthorised Charges on Credit Card
Identity theft tops the list. Criminals buy stolen card details on the dark web and test small amounts first. Then they ramp up. You might see tiny test charges followed by bigger ones.
Another big culprit is subscription traps. You sign up for a free trial of a streaming service or fitness app, forget to cancel, and it auto-renews. Or phishing emails trick you into entering your card info on a fake site.
Sometimes it is not even malicious. Your teen might have used the card for a game purchase. Or a recurring bill from a service you cancelled months ago still processes because the company did not get the memo.
Here is a simple table to help you match what you are seeing:
| Charge Type | Typical Amount | Likely Cause |
|---|---|---|
| Small test charge | $1 – $5 | Fraudster checking the card |
| Subscription fee | $9.99 – $49.99 | Forgotten free trial |
| One-off purchase | $20 – $150 | Phishing or shared card misuse |
| Large unknown buy | $200+ | Full identity theft |
Does your charge fit any of these? That is your first clue.
Immediate Steps When You Spot Unauthorised Charges on Credit Card
Do not wait. The faster you act, the better your protection. First, grab your phone and call the number on the back of your card. Tell them you see unauthorised charges. They will likely freeze your card right away and issue a new one with a new number.
Most major issuers (Visa, Mastercard, American Express) offer zero liability on credit cards for fraud. That means you pay nothing if you report it promptly. Debit cards have different rules, often up to $50, so credit cards are safer for online shopping.
Next, change passwords on any accounts linked to that card. Enable two-factor authentication everywhere. Then, check your other statements for more surprises.
Real story from a reader in New York: She spotted three small charges from a site she never used. One quick call to her bank, and they reversed everything within 48 hours. She lost zero dollars and slept easy again.
How to Formally Dispute Unauthorised Charges on Credit Card
After the phone call, follow up in writing. Most banks want a letter or online dispute form within 60 days of the statement date. Include the date, amount, and why it is unauthorised. Keep copies of everything.
Under the Fair Credit Billing Act in the US, the issuer must investigate within 30 days and usually fix it within two billing cycles. You do not pay the disputed amount while they look into it.
If the charge is under $50, some issuers handle it even faster with no paperwork. But for bigger amounts, the written dispute is your safety net.
While you wait, monitor your account daily through the app. Set up transaction alerts so every future purchase texts or emails you instantly. It is free and catches problems the second they happen.
Prevention Tips to Avoid Unauthorised Charges on Credit Card Forever
Prevention is way easier than fixing. Start by using virtual card numbers for online shopping. Many banks let you create a one-time number that expires after the purchase. Perfect for sketchy sites.
Turn on all alerts in your banking app. Choose text or email for every transaction over $1. You will know about any weird charge before the statement arrives.
Never enter your card details on suspicious links. Hover over emails to check the real web address. And review your saved payment methods monthly on sites like Amazon or PayPal. Delete anything old.
For extra safety, freeze your credit with Equifax, Experian, and TransUnion. It stops new accounts from opening in your name. It is free and takes five minutes online.
One more tip I swear by: Use a separate credit card just for online buys. Keep your main card for in-person use only. That way, if one gets compromised, the damage stays small.
FAQs: Unauthorised Charges on Credit Card
Q. What should I do first if I see unauthorised charges on my credit card?
A. Call your credit card issuer immediately using the number on the back of your card. Report the charges as unauthorised and ask them to freeze your account. This stops any further damage and starts the protection process right away. Most issuers can reverse the charges on the spot if they look fraudulent.
Q. Will I have to pay for unauthorised charges on credit card?
A. In almost every case, no. Credit card companies offer zero liability protection for fraud when you report it quickly. You are not responsible for charges you did not authorise. Debit cards are different and may leave you on the hook for up to $50, so always use credit for bigger purchases.
Q. How long do I have to report unauthorised charges on credit card?
A. You usually have 60 days from the date your statement was mailed or posted online. After that, your rights under the law get weaker. Act within the first week if possible for the smoothest and fastest resolution. Banks love quick reports because it helps them catch patterns of fraud.
