The most effective ways to prevent identity theft are to freeze your credit at all three bureaus, secure your email with a unique password and two-factor authentication, and never share codes or personal details with anyone who contacts you first. After that, reduce how much of your personal information is publicly listed, get an IRS Identity Protection PIN, and check your accounts and credit reports regularly so you catch problems early.
No single step makes you immune. Identity theft prevention works in layers: each one makes you a harder target, and together they close most of the doors criminals use. Here are 12 steps, starting with the ones that do the most.
Why prevention matters more than ever
Much of the information used to steal identities (names, dates of birth, addresses, even Social Security numbers) has already leaked in data breaches you had no control over. You can’t pull that information back. What you can do is make it much harder for someone to use it: to open credit in your name, take over your accounts or file a tax return as you.
That’s why the best way to prevent identity theft is less about hiding your data and more about locking the places where stolen data gets turned into money.
The 12 steps to prevent identity theft
1. Freeze your credit at all three bureaus
A credit freeze stops most lenders from pulling your credit report, which means a thief usually can’t open a new card or loan in your name. In the US, freezing and unfreezing your credit is free by federal law. You need to place a freeze separately with each of the three nationwide credit bureaus: Equifax, Experian and TransUnion. You can do it online or by phone, and you can lift it temporarily when you apply for credit yourself.
A freeze doesn’t affect your credit score or your existing accounts. For most people, it is the single most useful step on this list.
2. Secure your email account
Your email is where password resets land. If someone controls it, they can take over your bank, shopping and social media accounts one by one. Give it a long, unique password, turn on two-factor authentication (an authenticator app, security key or passkey is stronger than text codes), and check the recovery phone number and backup email are yours.
3. Use unique passwords and a password manager
When one site is breached, criminals try the leaked email and password combination on other sites. Unique passwords stop one breach from becoming ten. A reputable password manager generates and stores them so you only need to remember one strong master password. Where a site offers passkeys, they’re generally even harder to phish.
4. Turn on two-factor authentication everywhere that matters
Start with email, banking, mobile carrier, cloud storage and social media. Even if a password leaks, a second factor stops most account takeovers.
5. Protect your phone number
Criminals sometimes persuade a carrier to move your number to their SIM card, then receive your text message codes. Ask your mobile carrier about account PINs, passcodes or port-out protection, and set them up. Don’t publish your mobile number widely if you can avoid it.
6. Get an IRS Identity Protection PIN
The IRS offers an Identity Protection PIN (IP PIN) to anyone who can verify their identity. It’s a six-digit number that must be included on your federal tax return, which makes it much harder for someone else to file a fraudulent return using your Social Security number. You can request one through your IRS online account, and a new PIN is issued each year.
7. Never share codes or personal details with someone who contacts you
Banks, government agencies and tech companies won’t call, text or email to ask for your password, a one-time code or your full Social Security number. If someone claims to be from your bank or the IRS, hang up and contact the organization using a number or website you look up yourself. Scammers are good at sounding official and creating urgency. Slowing down is your best defense.
8. Guard your Social Security number
Only give your SSN when it’s genuinely required, such as for employment, tax or credit applications. When a doctor’s office, school or business asks for it, ask why they need it and whether another identifier will do. Don’t carry your card in your wallet. If your number has already been exposed, our guide on what to do when your Social Security number is stolen covers the next steps.
9. Reduce what data brokers publish about you
People-search and data broker sites compile addresses, phone numbers, relatives and ages, which is exactly the information used to answer security questions or impersonate you. Most offer an opt-out process. It takes time, and listings can reappear, but removing the main ones cuts down what a criminal can find in minutes. Our data broker opt-out list walks through where to start, and our guide to removing yourself from people-search sites covers the process in detail. Paid data removal services exist too; they can save time, but they use the same opt-out routes you can use yourself.
10. Handle mail and paper carefully
- Shred documents with account numbers, your SSN or medical details before throwing them away.
- Collect mail promptly, and consider a locking mailbox if mail theft is a problem where you live.
- Opt for paperless statements where it makes sense.
- USPS Informed Delivery lets you preview incoming letter mail, which can help you notice if something expected goes missing.
11. Keep devices and software updated
Updates fix security holes that malware uses. Turn on automatic updates for your phone, computer, browser and apps. Lock your phone with a PIN or biometric. Avoid logging into financial accounts on public computers, and be cautious with public Wi-Fi for sensitive tasks.
12. Monitor your accounts and credit reports
Prevention includes catching problems early. Turn on transaction alerts from your bank and card issuers. You can get free credit reports from each of the three bureaus at AnnualCreditReport.com, which is the official site for free reports under federal law; weekly free reports are now available there. Look for accounts, addresses or inquiries you don’t recognize.

This is an illustrative scenario, not a real case.
A couple receives a letter saying their health insurer was involved in a data breach that exposed names, dates of birth and Social Security numbers. Rather than worry, they spend one Saturday morning on prevention.
They freeze their credit at Equifax, Experian and TransUnion, and freeze their teenage son’s credit too, since children’s identities can be misused for years before anyone notices. They each request an IRS Identity Protection PIN. They move their email accounts to authenticator app codes, set up a shared password manager and ask their mobile carrier to add a port-out PIN. Over the next few weeks, they work through the main people-search sites listing their address and phone number. They set a calendar reminder to pull free credit reports every few months. None of this undoes the breach, but it closes the routes someone would most likely use.
Identity theft prevention programs for businesses
If you run a business, you may have heard the phrase identity theft prevention program in a regulatory context. Under the FTC’s Red Flags Rule, certain financial institutions and creditors that offer or maintain covered accounts must have a written Identity Theft Prevention Program. The program must identify warning signs of identity theft (red flags), detect them in day-to-day operations, respond appropriately and be updated over time.
Whether the rule applies to you depends on your business and how you extend credit, so check the FTC’s guidance and talk to a lawyer or compliance advisor if you’re unsure. Even if it doesn’t apply, the same thinking protects customers: verify identities before changing account details, limit who can see sensitive data and train staff to recognize social engineering. If customer data is ever exposed, our guide to data breach communication covers how to tell people.
Common mistakes to avoid
- Freezing only one bureau. Lenders may check any of the three. Freeze all of them.
- Relying only on monitoring. Monitoring tells you after something has happened. A freeze helps stop it happening.
- Using text codes as your only second factor on email. They’re better than nothing, but an authenticator app or passkey is harder to intercept.
- Trusting caller ID. Phone numbers can be spoofed to look like your bank. Call back on a number you look up yourself.
- Oversharing online. Birthdays, pet names, schools and hometowns are common security question answers.
If it happens anyway
Even with good habits, identity theft can happen. Act quickly: report it at IdentityTheft.gov, the FTC’s official site, which creates a personalized recovery plan. Contact the companies where fraud occurred, and freeze your credit if you haven’t already. Our guide on what to do if your identity is stolen walks through the full process.
Sometimes identity theft spills into your reputation: fake profiles, debts reported in your name or damaging content tied to your name in search results. If that’s happening, our personal reputation management service can help you work out what can be corrected or removed.
Frequently asked questions
What is the best way to prevent identity theft?
For most people, freezing your credit at Equifax, Experian and TransUnion is the single most effective step, because it blocks most new accounts opened in your name. Combine it with a secured email account, unique passwords and two-factor authentication.
Does a credit freeze hurt my credit score?
No. A credit freeze doesn’t affect your credit score or your existing accounts. You can lift it temporarily, for free, when you want to apply for new credit.
Are identity theft protection services worth it?
They can help with monitoring and recovery support, but most of their core protections, such as credit freezes, fraud alerts and credit report checks, are things you can do yourself for free. Consider what they offer beyond that before paying.
Should I freeze my child's credit?
In many cases it’s worth considering, because a child’s identity can be misused for years before anyone checks. Each credit bureau has a process for parents or guardians to request a freeze for a minor.
Can I stop my information from being leaked in data breaches?
Not entirely, because breaches happen at companies that hold your data. You can limit the damage by sharing less, using unique passwords, freezing your credit and removing your details from data broker sites.
