How to Freeze Your Credit: Step-by-Step Guide
A credit freeze is the single most effective defense against identity theft, and since 2018, it's completely free. Yet only 12% of Americans have frozen their credit, while identity thieves opened 1.4 million fraudulent new accounts using stolen personal information in 2025. A credit freeze would have prevented the vast majority of those cases.
Freezing your credit takes about 10 minutes per bureau (30 minutes total for all three), costs nothing, and prevents anyone — including you — from opening new credit accounts until you temporarily lift the freeze. It doesn't affect your credit score, existing accounts, or ability to use your current credit cards.

What a Credit Freeze Does (and Doesn't Do)
When someone applies for a credit card, loan, or mortgage, the lender checks your credit report. If your credit is frozen, the bureau blocks access to your report, and the application gets denied — whether it's from you or a thief using your Social Security number.
What a freeze blocks:
- New credit card applications
- Loan applications (auto, personal, mortgage)
- New cell phone contracts (those that require a credit check)
- Utility account openings (in some cases)
- Apartment rental applications (credit check portion)
What a freeze does NOT affect:
- Your existing credit cards and loans — they work normally
- Your credit score — it continues to be calculated and updated
- Your ability to check your own credit
- Employment background checks (in most states)
- Insurance quotes
- Pre-approved credit offers (use optoutprescreen.com to stop those separately)
Step-by-Step: Freezing at All Three Bureaus
You must freeze at all three major credit bureaus separately. If you only freeze one, thieves can still access your report through the other two.

How to Temporarily Lift a Freeze
When you need to apply for credit, you temporarily lift ("thaw") the freeze. This can be done for a specific time period (one day is usually enough) or for a specific creditor.
Each bureau allows you to lift the freeze online using the PIN you saved. The lift typically takes effect within minutes for online requests. You can set it to automatically re-freeze after a specified date.
Plan ahead: if you're applying for a mortgage or car loan, ask the lender which credit bureau(s) they use. You may only need to thaw one bureau instead of all three.
IsThisAScam's 6-layer detection system can help identify phishing emails impersonating credit bureaus — scammers often send fake "credit alert" emails designed to steal your credit bureau login credentials and PIN.
Credit Freeze vs. Credit Lock vs. Fraud Alert
Credit freeze (recommended): Free by law, enforced by federal regulation, requires PIN to lift. Maximum protection.
Credit lock: Offered by credit bureaus as a premium product. Functionally similar to a freeze but governed by the company's terms of service rather than federal law, which gives you weaker legal protections. Often bundled with paid monitoring services. There's little reason to choose a lock over a freeze.
Fraud alert: A note on your credit report asking lenders to verify your identity before approving applications. It's free and easy to set, but it's only a request — lenders aren't legally required to comply. Much weaker than a freeze.
What to Do If You're Already a Victim
If someone has already opened accounts in your name:
- Freeze your credit immediately at all three bureaus
- File an identity theft report at identitytheft.gov
- File a police report (you may need this for disputes)
- Contact each company where fraudulent accounts were opened
- Place an extended fraud alert (lasts 7 years) through any bureau
- Review your credit reports at annualcreditreport.com (free weekly)
- Consider an IRS Identity Protection PIN if your SSN was compromised

Freeze Your Children's Credit Too
Children's Social Security numbers are prime targets for identity theft because the fraud often goes undetected for years. All three bureaus allow parents to freeze their children's credit. The process requires submitting documentation proving your relationship, but it's worth the effort — one in 50 children is affected by identity fraud.
Frequently Asked Questions
Does a freeze hurt my credit score? No. Not at all. Your score is unaffected.
Can I still use my existing credit cards? Yes. A freeze only prevents new account openings.
How quickly can I lift a freeze? Online lifts typically take effect within 15 minutes.
What if I lose my PIN? Each bureau has an identity verification process to recover or reset your PIN.
Should I pay for credit monitoring instead? Monitoring tells you after fraud has occurred. Freezing prevents it from happening. Do both if possible — freeze for prevention, monitor for detection.
