In 60 seconds: A credit freeze is free, takes minutes at each of the three credit bureaus, doesn't touch your credit score, and blocks anyone — including an identity thief with your Social Security number — from opening new credit in your name. Here's how to do it right, and the one mistake that leaves a gap.
- A credit freeze is free to place and free to lift at Equifax, Experian, and TransUnion, and it lasts until you lift it.
- You must freeze at all three bureaus separately — a freeze at one does not cover the other two.
- A freeze does not affect your credit score or your existing accounts; it only blocks new creditors from pulling your report.
- Lifting a freeze online or by phone must happen within one hour; by mail it can take three business days.
- A freeze is not a lock: locks are bureau products that may charge a monthly fee, while a freeze is guaranteed free by federal law.
Honestly, this is the single highest-value, lowest-effort money move most Americans never make. It costs nothing, it takes about fifteen minutes total, and it closes the exact door identity thieves walk through: a lender opening a shiny new account in your name because they could pull your credit file without asking you first.
Here's the thing most guides bury: a freeze isn't magic, and it isn't a one-click fix. It's three separate freezes, at three separate companies, and skipping even one of them leaves the door open. Do all three, do them properly, and you're done — until the day you actually want credit yourself.

What a credit freeze actually does
When your credit is frozen, creditors can't access your credit report. Since lenders usually won't approve new credit without reviewing that report, a freeze stops a thief from opening a credit card, loan, or store account in your name — even if they have your Social Security number, address, and date of birth. The Federal Trade Commission puts it plainly: while a freeze is in place, nobody can open a new credit account in your name.
What a freeze does not do matters just as much. It doesn't affect your credit score. It doesn't close or freeze your existing cards, bank accounts, or loans — you can keep using those normally. It doesn't stop debt collectors, your existing creditors, or government agencies from accessing your file where the law allows. And it doesn't protect accounts you already have from being misused; that's a different problem, solved with strong passwords, two-factor authentication, and account alerts.
How to freeze your credit at all three bureaus
Contact each bureau separately — online is fastest, phone works, mail is slowest. Go to the bureau's own site directly (start from the FTC's consumer advice pages if you want a safe jumping-off point), never through a link in an unexpected text or email claiming your identity was stolen. Each bureau will verify your identity and let you place the freeze in a few minutes. Save every confirmation and your account-recovery details somewhere safe.
| Bureau | How to freeze | Timing (federal rules) |
|---|---|---|
| Equifax | Online, phone, or mail via Equifax's credit freeze service | Online/phone: within 1 business day; mail: within 3 business days |
| Experian | Online, phone, or mail via Experian's freeze service | Online/phone: within 1 business day; mail: within 3 business days |
| TransUnion | Online, phone, or mail via TransUnion's credit freeze service | Online/phone: within 1 business day; mail: within 3 business days |
The one mistake that leaves you exposed is freezing at only one bureau and assuming you're covered. The bureaus operate independently, creditors don't all check the same one, and the FTC's advice is explicit: contact all three. A thief only needs one unfrozen file. Do all three in one sitting, and the job is actually done.
Freeze vs fraud alert vs lock — don't mix them up
A fraud alert is the lighter option. You place it at one bureau and that bureau tells the other two; an initial fraud alert lasts one year and tells lenders to verify your identity before granting new credit. It's useful, but it doesn't block access the way a freeze does — it asks lenders to take an extra step. Victims of identity theft can get an extended fraud alert lasting seven years.
A credit lock looks similar and is often marketed inside bureau apps, but locks are commercial products that may carry a monthly fee and different terms. If you want the free protection guaranteed by federal law, choose the freeze, not the lock. And never pay anyone simply to place a standard freeze — the bureaus must provide it free.
How to lift a freeze when you need credit
Applying for a mortgage, car loan, apartment, or credit card? Ask the lender which bureau it will check, lift just that one, and refreeze when you're done. A temporary lift — for a set period — is usually the safest choice, because the freeze returns on its own without another step. If the lender can't say which bureau it uses, lift all three for the shortest practical window, then confirm each file is frozen again afterward.
Plan ahead: online or phone lift requests must be handled within one hour, but don't leave it to the last minute at a dealership or a rental office. Lift before you apply, not during. Parents can also place free freezes for children under 16, and guardians or people with a valid power of attorney can freeze for the person they represent — worth doing, since a child's clean file is a prime target precisely because nobody checks it for years.
What happens next
Once all three freezes are in place, set a simple routine: check your credit reports regularly (you're entitled to free weekly reports), keep your bureau logins and PINs somewhere secure, and if your identity is ever actually stolen, report it at IdentityTheft.gov, where you'll get a free, personalized recovery plan. A freeze plus a fraud alert plus regular report checks is about as strong a posture as a regular person can have — and all of it is free.
Our take: if you do one money task this week, make it this one. Fifteen minutes, zero dollars, and the most common form of identity theft gets dramatically harder overnight. The only wrong way to do it is halfway — one bureau frozen, two wide open, feeling safe. Do all three, save the confirmations, and move on with your life.
Frequently asked questions
Does freezing my credit hurt my credit score? No. The FTC confirms a freeze doesn't affect your credit score, and it doesn't affect your existing accounts either.
Do I really need to freeze at all three bureaus? Yes. Each bureau holds its own file, and a freeze applies only where you place it. Freezing one leaves the other two open to any lender who checks there.
How fast can I lift a freeze when I need a loan? Online or phone lift requests must be handled within one hour; mailed requests within three business days. A temporary lift is usually safest.
Is a credit lock the same as a credit freeze? No. Locks are bureau products that may charge monthly fees; a freeze is free under federal law. Choose the freeze for guaranteed free protection.
Can I freeze my child's credit? Yes — free freezes are available for children under 16, and guardians or attorneys-in-fact can freeze for the person they represent.
