A credit freeze is one of the most effective and underused tools for protecting yourself from identity theft. It’s free, takes about 15 minutes to set up at all three credit bureaus, and prevents almost any new credit account from being opened in your name. Here’s how it works and when you’d want to use it.
What a Credit Freeze Does
When your credit is frozen, the three major credit bureaus — Equifax, Experian, and TransUnion — will not release your credit report to new lenders. Since almost any credit application (credit card, car loan, mortgage, store card, even most cell phone contracts) requires the lender to pull your credit, a freeze effectively blocks new accounts from being opened in your name.
Someone who has stolen your Social Security number or personal information can still try to apply for credit — but when the lender can’t pull a report, the application is almost always denied. The freeze does the work without you having to monitor anything in real time.
What a Freeze Does NOT Do
- It doesn’t affect your credit score or appear on your credit report.
- It doesn’t stop you from using your existing credit cards or loans — existing creditors don’t need to pull a fresh report.
- It doesn’t prevent someone from making fraudulent charges on an existing card — that’s a separate problem the card issuer handles.
- It doesn’t block all fraud — tax-refund fraud, medical identity theft, and unemployment fraud use different systems.
- It doesn’t protect you if the thief has access to your existing accounts (different problem — change passwords, contact the bank).
Why Credit Freezes Became Standard
After the 2017 Equifax data breach exposed personal information for roughly 147 million Americans, Congress passed legislation making credit freezes free at all three bureaus. Before that, freezes cost $5–$10 per bureau per action. Now they cost nothing, and you can place or lift one at any time, online or by phone.
After the 2024 National Public Data breach — which exposed Social Security numbers for an even larger group — the FTC and many state attorneys general specifically recommended freezing credit as a baseline protection.
How to Freeze Your Credit
You must freeze your credit separately at each of the three bureaus. It takes about 5 minutes per bureau:
- Equifax — equifax.com/personal/credit-report-services. Create an account or sign in, choose “Place a security freeze.”
- Experian — experian.com/freeze. Same process: create account, freeze.
- TransUnion — transunion.com/credit-freeze. Same process.
Each bureau will issue you a PIN or password used to lift the freeze later. Save these somewhere you’ll find them — password manager, encrypted file, or written down and locked away. You’ll need them to unfreeze.
You can also place a freeze by phone or by mail if you prefer. Each bureau lists the alternatives on its website.
When You’ll Need to Unfreeze
A freeze blocks legitimate credit applications too. You’ll need to temporarily lift it any time you:
- Apply for a credit card
- Apply for a car loan, mortgage, or personal loan
- Rent an apartment (most landlords pull credit)
- Sign up for a new cell phone contract or utility service
- Start a new job that runs a credit check (some employers do)
Unfreezing online is usually instant. You can specify how long to lift the freeze (one day, a week, until a specific date) or which specific bureau to thaw — some lenders only pull from one bureau, so you don’t always need to unfreeze all three. Most lenders will tell you which bureau they use if you ask.
Credit Freeze vs Credit Lock vs Fraud Alert
These three protections sound similar but work differently:
- Credit freeze — free, governed by federal law, blocks new credit. The strongest baseline option.
- Credit lock — an app-based product sold by each bureau. Often paid; some are free as part of a monitoring service. Functionally similar to a freeze but governed by the bureau’s terms of service, not federal law. Easier to toggle on and off via an app.
- Fraud alert — a free flag on your credit report that asks lenders to verify your identity before opening new credit. Doesn’t block applications. Initial alerts last 12 months; extended alerts (for confirmed identity theft victims) last 7 years.
For most people, the freeze is the best choice: it’s free, federally protected, and the strongest barrier. Add a fraud alert too if you’ve already been a confirmed identity theft victim.
Freezing a Child’s Credit
Children typically don’t have credit reports until someone applies for credit using their identity — which is exactly why child identity theft is so damaging (it can go undetected for years). Under federal law, parents and guardians can request a credit freeze for a minor child. Each bureau requires proof of identity and guardianship; details are on their websites under “Child credit freeze.”
Should Everyone Freeze Their Credit?
In most cases, yes — especially if:
- Your Social Security number was exposed in a known breach (most Americans’ data has been at this point).
- You don’t apply for credit often.
- You’ve been a victim of identity theft.
- You’re retired or no longer need to open new accounts regularly.
If you apply for credit frequently — rotating credit card sign-up bonuses, for example — a lock app might be more convenient. But for the average person, a freeze is the simpler and stronger protection.
