A credit freeze is the single most powerful thing you can do to stop identity theft — and almost nobody uses it, because they assume it’s complicated or costs money. It’s neither. It’s free, it takes about ten minutes, and it blocks criminals from opening new accounts in your name even if they have your Social Security number. Here’s exactly how to freeze your credit at all three bureaus.
What a freeze does (and doesn’t)
A credit freeze locks your credit reports so no one can open new credit in your name — because lenders can’t pull your report to approve an application. It does not affect your existing accounts, your credit score, or your ability to use current cards. It’s a lock on new borrowing, and since 2018 US law makes it free to freeze and unfreeze, for you and your kids.
Know the three bureaus you must contact
You have to freeze at all three credit bureaus separately, because lenders may check any of them: Equifax, Experian, and TransUnion. A freeze at only one leaves the door open at the other two. Set aside a few minutes for each; it’s the same process three times.
Go to each bureau’s official site
Freeze online for the fastest results at the bureaus’ real websites (equifax.com, experian.com, transunion.com) — or by phone if you prefer. You’ll create an account and verify your identity by answering questions only you should know. Be sure you’re on the genuine site; type the address yourself rather than following a link from an email.
Don’t confuse a freeze with a credit lock or “credit monitoring” the bureaus try to upsell. A freeze is the free legal protection. Some bureaus nudge you toward paid products with similar names — you don’t need them. Look specifically for “Security Freeze,” and skip anything asking for a monthly fee.
Save your PINs and login details
Each bureau gives you a PIN or account login you’ll need to lift the freeze later. Store these somewhere safe (a password manager is ideal). Losing them makes unfreezing more of a hassle — you can recover access, but it’s smoother if you keep the details handy from the start.
Learn to “thaw” it when you need credit
Because a freeze blocks new applications, you’ll need to temporarily lift it when you apply for a card, loan, apartment, or sometimes a phone plan. You can unfreeze all three or just the one bureau a specific lender uses, for a set window or permanently — online in minutes, for free. Plan a day ahead when you know you’re applying for something.
Consider freezing your kids’ credit too
Child identity theft is nasty because it often goes unnoticed for years. If you’re a parent or guardian, you can freeze a minor’s credit for free as well — it requires sending documents to verify the relationship, but it shuts down a whole category of fraud before it can start. It’s a quiet, powerful thing to set up once.
A freeze doesn’t protect existing accounts from misuse, so keep watching your statements and set up transaction alerts. For an extra layer, you can also place a free fraud alert (which tells lenders to verify your identity) — but the freeze is the stronger lock. Use both if you’ve already been a victim.
If you’re already an identity-theft victim
If someone has already opened accounts in your name, freezing is step one but not the whole response. Go to IdentityTheft.gov, the FTC’s official recovery site — it walks you through a personalized action plan and generates the reports and letters you need. Freeze all three bureaus immediately, then dispute the fraudulent accounts with both the bureaus and the businesses involved, file an FTC identity theft report (it carries legal weight), and file a police report if a creditor requires one. Change the passwords on your email and financial accounts, and turn on two-factor authentication everywhere. It’s a stressful process, but it’s a well-worn path with clear steps — and the freeze you put in place stops the thief from opening anything new while you clean up the rest.
Freezing your credit is free, quick, and the best defense against someone opening accounts in your name. Do it at all three bureaus — Equifax, Experian, and TransUnion — save your PINs, and simply thaw it for a few days whenever you apply for new credit. It won’t touch your score or existing accounts. Freeze your kids’ credit too. Ten minutes now can save you months of identity-theft cleanup.
Quick questions
Does freezing my credit hurt my score?
No. A freeze has zero effect on your credit score. It simply prevents new lenders from pulling your report, which is what stops fraudulent new accounts.
Is it really free?
Yes — since 2018, freezing and unfreezing your credit is free by federal law at all three bureaus, for you and for your minor children. Don’t pay for it.
What happens when I want a new credit card or loan?
You temporarily lift (“thaw”) the freeze — all three bureaus or just the one the lender uses — for a set period, then it re-freezes. It’s free and takes minutes online, so plan a little ahead when applying.
Freeze vs. fraud alert — what’s the difference?
A freeze blocks access to your report entirely (stronger); a fraud alert asks lenders to verify your identity but still lets them pull your report. A freeze is the better lock; you can use both, especially after identity theft.
