Why Your Credit Card Gets Hacked and How to Stop It

Your card gets hacked because criminals have many ways to steal the numbers, and some methods work even when you're careful

A hacked credit card usually means a criminal has your card number, expiration date, and sometimes your CVV (the three-digit code on the back). They don't need the physical card itself — just those numbers. Once they have them, they can make purchases online or over the phone, or sell the numbers to other criminals. If your card keeps getting hacked, it's often not because you did something wrong. It's usually because your number was exposed in a data breach at a store or website, or because criminals are using your number from an earlier theft.

The reason you might see repeated fraud is that your card number stays the same even after you report one fraudulent charge. If the criminal still has your number, they can try again. Your bank will catch most of it and refund you, but the cycle repeats until you get a new card with a new number.

Key Takeaways

• Most credit card fraud comes from data breaches at stores and websites, not from your own mistake or careless spending habits.
• Your card number can be stolen without the physical card leaving your wallet, through online breaches, skimming devices, or mail theft.
• Repeated fraud on the same card usually means the criminal still has your old number, so getting a replacement card with a new number is the most effective fix.
• Monitoring your statements weekly and setting up transaction alerts catches fraud faster than waiting for your monthly bill.
• Chip readers and contactless payments are harder to skim than magnetic stripe cards, but online fraud still happens regardless of how you physically pay.

How criminals get your card number in the first place

Data breaches at retailers and websites are the most common source. When a store's payment system gets hacked, criminals can steal thousands of card numbers at once. You might not know the breach happened for months. Major breaches at chains like Target, Home Depot, and Equifax exposed millions of card numbers over the years. Your number could have been sitting in a criminal database for a long time before it's used.

Skimming devices are another method. A skimmer is a small reader that criminals attach to an ATM, gas pump, or payment terminal. When you swipe or insert your card, the skimmer copies your number. The criminal then retrieves the device later. Chip readers have made this harder at some locations, but skimmers still work on older machines and in places criminals can access easily.

Phishing emails and fake websites also steal card numbers. A criminal sends you an email that looks like it's from your bank or a store you use, with a link to a fake login page. If you enter your card details, the criminal captures them. Mail theft is simpler: a criminal steals your credit card statement or a new card from your mailbox before you receive it.

Why you might see fraud multiple times on the same card

Once a criminal has your card number, they often test it with a small purchase first — sometimes just a dollar or two. If that goes through, they know the number is active and your bank hasn't blocked it yet. They may then make larger purchases or sell your number to other criminals. Each time your bank catches fraud and refunds you, your card number is still out there in the criminal's hands or in a database being shared.

Your bank will usually send you a new card after you report fraud, but only if you ask or if the fraud happens multiple times in a short period. Some banks are faster than others. If you've had fraud twice in a month, call your bank and request a replacement card immediately rather than waiting for them to offer one. A new card means a new number, which stops the old number from being used.

What to do when your card gets hacked

Call your bank's fraud line as soon as you notice an unauthorized charge. The number is on the back of your card or your statement. Do not use a number from an email or text message, because those could be fake. Your bank will cancel the fraudulent charge, usually within one to three business days, and refund the money to your account. They will also ask you questions about the charge to confirm it wasn't you.

Request a replacement card with a new number. Tell your bank you want it expedited if possible — many banks can send a replacement within three to five business days. Ask whether they can issue a temporary card number you can use online while you wait for the physical card. Update any recurring payments (subscriptions, autopay bills) with your new card number once you receive it, so those charges don't fail.

Check your credit report for accounts you didn't open. You can view your report free once a year at AnnualCreditReport.com, which is the official government site. If a criminal opened a credit card or loan in your name, you'll see it there. Report it to the credit bureau and the company that issued the account.

Steps to reduce the chance of repeated fraud

Monitor your statements weekly instead of waiting for your monthly bill. Log into your bank's app or website and scan recent transactions. The faster you spot fraud, the faster you can report it and get a new card. Many banks also let you set up alerts that notify you by text or email when a charge over a certain amount is made, or when any online purchase happens. These alerts catch fraud within minutes instead of days.

Use your card's chip reader when you have the option. Chip technology is harder to skim than the magnetic stripe on the back. When you insert your card into a chip reader, the transaction creates a one-time code that can't be reused. Swiping the magnetic stripe creates the same number every time, which is easier for criminals to copy. At gas pumps and ATMs, use ones inside a bank or busy location rather than isolated machines, which are easier targets for skimmers.

For online shopping, use a virtual card number if your bank offers one. Some banks, like Citi and Bank of America, let you generate a temporary card number for online purchases. The temporary number is linked to your real card but can only be used once or for a specific merchant. If that number gets stolen, it's useless to a criminal because it won't work again.

When to consider switching banks or card issuers

If you've had fraud on the same card three or more times in six months, and your bank hasn't offered better fraud protection or a faster replacement process, it may be time to switch. Some banks are more proactive about fraud prevention than others. Call your bank and ask what fraud prevention tools they offer — things like real-time alerts, virtual card numbers, or zero-liability policies. If they don't have these, a different bank might.

Switching cards doesn't prevent future breaches, because the breach happens at the store or website, not at your bank. But a new bank might offer better tools to catch fraud faster. You can keep your old account open while you test a new card, so you don't lose the account history or rewards you've built up.

What you probably aren't doing wrong

If your card keeps getting hacked, it's usually not because you shared your number carelessly or used it on an unsafe website. Most people who experience repeated fraud are actually careful with their cards. The breach usually happened at a major retailer or website that you trusted, and the criminal got your number along with thousands of others. You didn't cause it, and you can't prevent every breach by being more cautious.

Using your card online is not inherently riskier than using it in a store, despite what many people believe. Online fraud and in-store fraud happen at similar rates. The difference is that online fraud is often caught faster because your bank monitors for unusual patterns. In-store fraud might not show up until you check your statement.

Frequently Asked Questions

Do I have to pay for fraudulent charges on my credit card?

No. Federal law limits your liability to $50 if you report the fraud, and most credit card companies waive even that $50 if you report it quickly. Debit cards have different rules and higher liability, which is one reason credit cards are safer for fraud protection. Report fraud as soon as you see it.

How long does it take to get a replacement card?

Standard replacement cards usually arrive within five to ten business days. Many banks offer expedited replacement for two to five business days if you request it when you report the fraud. Some banks can issue a temporary digital card number you can use immediately while you wait for the physical card.

Will my credit score go down if my card gets hacked?

No, fraud itself doesn't hurt your credit score. Your bank refunds the fraudulent charges, so they don't appear as unpaid debt. However, if a criminal opens new accounts in your name and doesn't pay them, that will damage your score. Check your credit report to make sure no unauthorized accounts were opened.

Should I close my card after fraud, or keep it open?

You can do either, but closing it immediately after getting a replacement card is simpler. If you keep the old card open, make sure you destroy it so no one else can use the number. The important thing is getting a new card with a new number, which stops the old number from being used again.

Can I prevent my card from being hacked?

You can reduce your risk but not eliminate it. Most fraud comes from breaches you can't control. What you can do is monitor your statements weekly, use chip readers when available, enable transaction alerts, and use virtual card numbers for online shopping. These steps catch fraud faster and make it harder for criminals to use your number repeatedly.
