What is Credit Card Fraud?

Credit card fraud refers to unauthorized charges made to a credit card account. This can occur through various methods:


Criminals steal credit card information by using a skimmer to swipe your card information from a credit card reader. This often occurs at gas stations, ATMs, and other machines where your card is swiped.


Fraudsters send fake emails or texts pretending to be from a trusted source to trick you into revealing personal and financial information. This information is then used to make fraudulent charges.

Data Breaches

Your credit card information is stolen from a retailer through a security breach and sold on the dark web. Criminals then use this data for fraudulent purchases.

Identity Theft

Someone illegally obtains your personal information to open fraudulent credit card accounts in your name and use them for criminal purposes.

No matter how it happens, credit card fraud can wreak havoc on your finances. The key is knowing how to detect it fast and take action.

How to Detect Credit Card Fraud

Here are some common signs that may indicate credit card fraud:

Unusual activity

The biggest red flag is seeing charges for purchases you didn’t make. Review your statements closely each month to ensure all charges are valid. Watch for small charges from unfamiliar vendors as criminals often test stolen card numbers with small amounts first.

Increased number of declines

If your card is suddenly declined repeatedly for routine transactions, it could mean your credit limit has been reached by fraudulent charges. Don’t ignore payment declines thinking the retailer made an error. Follow up promptly.

Missing statements

If your monthly statement doesn’t arrive on time, it could mean criminals have changed your billing address to hide fraudulent charges. Always follow up on late or missing statements.

Unexpected credit inquiries

Fraudsters will sometimes apply for new lines of credit in your name, which can generate inquiries on your credit report. Monitor your credit report regularly for unauthorized activity.

Debt collectors calling about unknown debts

Scammers who open fraudulent accounts in your name will often default on payments, prompting debt collectors to call. Don’t ignore these calls.

Denied account changes

If your request to change an account password, credit limit, or address is denied for no reason, it could be because criminals have already changed your information.

The registered credit card offers

Signing up for many credit cards in a short period can lower your credit score. The track offers you the opportunity to spot unusual patterns.

Protecting Yourself from Credit Card Fraud

If you suspect your credit card number has been compromised, act quickly to minimize damage and prevent additional fraud. Here are some tips:

Monitor Accounts Closely

Check your account activity daily to spot unauthorized transactions early. Set up transaction alerts through your bank to be notified immediately of suspicious purchases. Don’t wait for statements – review charges online often.

Report Suspicious Activity

Notify your card issuer immediately about potential fraud. Provide details about suspicious charges or activity. The sooner they are aware, the faster they can shut down fraudulent transactions.

Place a Fraud Alert on Your Credit Reports

An initial fraud alert requires creditors to verify your identity before opening new accounts. This makes it harder for criminals to use your information. Contact one of the three major credit bureaus to place an alert.

Reset Account Passwords Frequently

Changing your online account passwords regularly helps prevent criminals who may have stolen previous passwords. Use strong, unique passwords and two-factor authentication when possible.

Be Wary of Phishing Attempts

Don’t click links, download attachments, or provide information in response to unsolicited emails, texts, or calls asking for your details. Legitimate companies won’t ask for sensitive data this way.

Review Credit Reports and Scores

Identity thieves may take out loans or credit cards in your name. Checking your credit reports helps you find fraudulent accounts. Watch for unexplained dings to your credit score as well.

Consider a Credit Freeze

A credit freeze restricts access to your credit report, making it nearly impossible to open unauthorized accounts. If you won’t need new credit soon, temporarily freezing your credit files can help protect you.

Limit International Transactions

Using your credit card abroad increases fraud risk. Whenever possible, stick to credit cards that have embedded chip technology to enhance security. Notify your card issuer before traveling internationally.

Watch Out for Skimmers

Criminals install skimmers on ATMs and gas pumps to steal card information. Choose machines in highly visible locations, check for signs of tampering, and cover the keypad when entering your PIN. Pay inside the gas station instead of at the pump.

Be Cautious with Public Wi-Fi

Open wireless networks in coffee shops, hotels, and airports make it easy for fraudsters to intercept your data. Avoid accessing financial accounts or making purchases over public Wi-Fi.

Know Your Rights

The Fair Credit Billing Act provides consumer protection against fraudulent credit card charges. Contact your card issuer promptly about unauthorized charges – you may not be liable. Register your credit card and phone number with the Do Not Call Registry to reduce unwanted solicitations.
