What Are Some Ways You Can Limit or Prevent Identity Theft or Fraudulent Charges?

The Short Answer

You can limit or prevent identity theft and fraudulent charges by protecting your personal information, using strong account security, checking statements often, freezing or monitoring your credit, and acting quickly when you see suspicious activity. No method removes every risk, but strong habits can make you a harder target and reduce the damage if fraud happens.

The Federal Trade Commission recommends quick reporting through IdentityTheft.gov when personal information is stolen. Banks and credit card companies also give consumers ways to dispute unauthorized charges. The faster you notice and report suspicious activity, the easier it is to limit the financial damage.

Protect Your Personal Information

Identity theft often starts when someone gets access to information such as your Social Security number, date of birth, bank details, credit card number, email account, or online passwords. Treat these details like keys.

Avoid sharing sensitive information through email, text messages, or phone calls unless you started the contact and know the organization is legitimate. Scammers often pretend to be banks, delivery companies, government offices, employers, or tech support.

You should also shred papers that show account numbers, medical details, tax information, or financial records before throwing them away.

Use Strong Passwords and Multi-Factor Authentication

Weak or reused passwords make identity theft easier. If one website is breached and you reused the same password elsewhere, a thief may try it on your email, bank, shopping, or social media accounts.

Good password habits include:

• Use long, unique passwords for important accounts
• Avoid using your name, birthday, or simple phrases
• Use a password manager if you have many accounts
• Turn on multi-factor authentication whenever possible
• Change passwords quickly after a known breach

Your email account deserves special protection because password reset links often go there. If someone controls your email, they may be able to take over other accounts.

Monitor Bank and Credit Card Accounts

Do not wait until the end of the month to review your accounts. Check bank and credit card activity regularly so you can spot small test charges, unfamiliar subscriptions, or larger fraudulent purchases.

Many banks allow alerts for:

• Purchases over a chosen amount
• Online or international transactions
• ATM withdrawals
• Low balances
• Card-not-present purchases

Alerts do not prevent all fraud, but they help you respond quickly. If you see a charge you did not make, contact the card issuer or bank immediately through the number on the back of your card or the official app.

Freeze Your Credit When You Do Not Need New Credit

A credit freeze restricts access to your credit report, which can make it harder for someone to open new credit accounts in your name. You can usually freeze and unfreeze your credit for free with the three major credit bureaus.

A credit freeze does not stop fraud on existing accounts. It mainly helps prevent new-account fraud, such as someone trying to open a credit card, loan, or financing account using your identity.

Credit monitoring can also help you spot new accounts or credit inquiries, but monitoring is not the same as prevention. A freeze is stronger when you are not actively applying for credit.

Be Careful with Public Wi-Fi and Shared Devices

Public Wi-Fi can be convenient, but avoid logging into financial accounts or entering sensitive information on unsecured networks. If you must use public Wi-Fi, use secure websites and consider a trusted VPN.

Shared devices are also risky. Do not save passwords on public computers, and always sign out of accounts when you finish. If you use a library, school, or workplace computer, avoid accessing banking, tax, or medical accounts unless necessary.

Watch for Phishing and Scam Messages

Phishing messages try to trick you into clicking links, opening attachments, or revealing personal information. They often create urgency: your account will be closed, your package is delayed, your payment failed, or your device is infected.

Before clicking, ask:

• Did I expect this message?
• Is the sender’s address legitimate?
• Is the link going to the real website?
• Is the message pressuring me to act immediately?
• Does it ask for private information?

When in doubt, go directly to the official website or app instead of clicking the message link.

Respond Quickly If Fraud Happens

If you suspect identity theft or fraudulent charges, act quickly. Contact the bank or card issuer, change affected passwords, review recent account activity, and report identity theft to the FTC if personal information was stolen.

You may also need to place fraud alerts, freeze credit reports, file a police report in serious cases, and keep records of every call, email, confirmation number, and dispute.
