A credit freeze (also called a “security freeze”) is a free, legal right that blocks anyone — including you — from opening a new credit account using your Social Security number until you lift it. It’s one of the strongest single steps you can take against identity theft, and unlike most security advice, it costs nothing and takes about fifteen minutes.
You don’t need to wait for a data breach notice or a police report to freeze your credit. Anyone can do it, for any reason, at any time — and if you’ve read our complete guide to identity theft recovery, this is very likely the single action on that list worth doing first.
Why a Credit Freeze Matters
Most identity theft that shows up on a credit report follows the same pattern: someone gets your Social Security number and name — through a data breach, a phishing scam, or stolen mail — and uses it to open a new credit card, auto loan, or line of credit in your name. A credit freeze stops that specific attack cold, because lenders can’t pull your credit file to approve the application in the first place.
A freeze doesn’t fix problems with accounts you already have open — it won’t stop someone from misusing a credit card you already own, and it doesn’t block employment or tenant screening checks you’ve already authorized. It’s specifically aimed at new accounts opened in your name, which is the most common form of credit-related identity theft.
Credit Freeze vs. Fraud Alert vs. Credit Lock: What’s the Difference?
These three terms get confused constantly, and credit bureaus don’t always explain the difference clearly — largely because “credit lock” is a product they sell, while a credit freeze is a right they’re required by federal law to give you for free.
| Tool | What It Does | Cost | How Long It Lasts |
|---|---|---|---|
| Credit Freeze | Blocks anyone, including you, from opening new credit until you lift it | Free, guaranteed by federal law | Indefinite, until you remove it |
| Initial Fraud Alert | Tells lenders to verify your identity before opening new credit; doesn’t block report access | Free | 1 year, renewable |
| Extended Fraud Alert | Same as initial alert, plus removes you from prescreened offer lists; requires an identity theft report | Free | 7 years |
| Credit Lock | A bureau-branded app feature that works similarly to a freeze, often instant via mobile app | Sometimes free, sometimes bundled into a paid monitoring plan | Until you unlock it |
None of these three tools include ongoing monitoring or identity theft insurance — they only control who can open new credit in your name. If you’re weighing whether to add a paid layer on top of a freeze, see Identity Protection Services: Are They Worth It?
How to Freeze Your Credit at All Three Bureaus
You have to contact Equifax, Experian, and TransUnion separately — freezing your file with one bureau does not freeze it with the other two. Under the federal law that took effect in September 2018, all three must freeze your file within one business day if you contact them online or by phone, or within three business days by mail, and it costs nothing.
| Bureau | Online | Phone |
|---|---|---|
| Equifax | equifax.com security freeze center | (888) 298-0045 |
| Experian | experian.com security freeze center | (888) 397-3742 |
| TransUnion | transunion.com credit freeze center | (800) 916-8800 |
The steps are nearly identical at each bureau:
- Go to the bureau’s security freeze page (linked above) or call the number listed.
- Create or log in to an account, and verify your identity — expect to provide your name, address, date of birth, and Social Security number.
- Set a PIN or password when prompted, and save it somewhere secure. You’ll need it later to lift the freeze.
- Confirm the freeze is active. Online requests are typically confirmed immediately; phone requests are confirmed within one business day.
- Repeat at the other two bureaus. Freezing at one does not freeze the others.
How to Temporarily Lift a Credit Freeze
You’ll need to lift your freeze any time you actually want a lender to check your credit — applying for a mortgage, a car loan, a new credit card, or even some rental applications and insurance quotes. Contact the specific bureau the lender will use (ask them which one if you’re not sure), request a temporary lift for either a set time window or a specific lender, and confirm with them once you no longer need it accessible. Lifting and re-freezing are both free and can be done as many times as you need.
Freezing Your Child’s Credit
Children under 16 generally shouldn’t have a credit file at all, which makes any credit report in their name a strong sign of identity theft. All three bureaus let a parent or guardian request a free freeze for a minor, but the process is different from an adult freeze — each bureau requires separate verification documents (proof of the child’s identity and your guardianship) submitted through their dedicated minor-freeze process rather than the standard online flow.
Common Mistakes People Make With Credit Freezes
- Freezing only one or two bureaus. A freeze at Equifax alone leaves Experian and TransUnion wide open — thieves who get rejected at one bureau will simply try the next.
- Losing the PIN or password. Bureaus have a recovery process, but it takes longer than just keeping the credential in a password manager the first time.
- Assuming a freeze replaces monitoring. A freeze blocks new accounts; it does nothing to alert you if an existing account is misused. Those are two different problems.
- Confusing a freeze with a lock and paying for something that’s free elsewhere. If a service is charging a recurring fee specifically for “credit lock,” compare it against the free freeze first — the protection against new-account fraud is functionally the same.
Credit Freeze Checklist
Use this list to track your progress across all three (or five) bureaus:
- ☐ Freeze your file at Equifax and save your PIN
- ☐ Freeze your file at Experian and save your PIN
- ☐ Freeze your file at TransUnion and save your PIN
- ☐ (Optional) Freeze your file at Innovis
- ☐ (Optional) Freeze your file at NCTUE
- ☐ Store all PINs/passwords in a password manager, not a sticky note
- ☐ Set a calendar reminder if you plan to apply for credit soon, so you remember to lift the freeze in advance

Frequently Asked Questions
Does freezing my credit hurt my credit score?
No. Placing, lifting, or removing a credit freeze has no effect on your credit score. It only controls who can view your file to open new credit, not the file’s contents.
Is a credit freeze really free?
Yes. Federal law has required all three major credit bureaus to freeze and unfreeze your credit for free since September 2018, with no expiration date on that requirement.
How long does a credit freeze last?
Indefinitely, until you personally request that it be removed. Unlike a fraud alert, it does not expire on its own.
What’s the difference between a credit freeze and a fraud alert?
A freeze blocks anyone from accessing your credit file to open new accounts; a fraud alert simply requires lenders to verify your identity first but still lets them view the file. A freeze is the stronger protection of the two.
Can I freeze my credit if I haven’t been a victim of identity theft?
Yes. Anyone can freeze their credit at any time, for any reason — you don’t need to prove theft, a breach, or any specific risk first.
Will a credit freeze stop someone from using my existing credit cards?
No. A freeze only blocks new accounts from being opened in your name. If an existing card or account is compromised, you need to contact that specific financial institution directly and monitor the account.
Do I need to freeze my credit at more than the big three bureaus?
It’s optional, but freezing at Innovis and the National Consumer Telecom and Utilities Exchange (NCTUE) closes gaps that the big three don’t cover, since some phone, utility, and specialty lenders check those files instead.
How do I unfreeze my credit temporarily?
Contact the specific bureau the lender will check, log in or call using the PIN or password you set when you froze it, and request a temporary lift for either a specific date range or a named lender.
