In 2017, the Equifax data breach exposed the personal information of 147 million Americans—including Social Security numbers, birth dates, and addresses. If you haven’t frozen your credit yet, consider this your wake-up call.

A credit freeze is the single most effective tool for protecting yourself against identity theft. It’s free, takes about 30 minutes to set up, and stops criminals from opening fraudulent accounts in your name. Yet most Americans still haven’t done it.

This guide will walk you through exactly how to freeze your credit at all three bureaus, when to temporarily lift the freeze, and how to manage your credit security going forward.

What Is a Credit Freeze?

A credit freeze (also called a security freeze) locks your credit file so that lenders cannot access your credit report. When criminals steal your identity, they typically try to open new credit cards, loans, or utilities in your name. To do this, the lender pulls your credit report. If your report is frozen, the pull fails—and so does the fraudulent application.

Think of it like locking your front door. It won’t prevent every possible break-in, but it stops the vast majority of casual attempts. And since freezing is now free by federal law, there’s no reason not to do it.

What a freeze does:

• Prevents new credit accounts from being opened in your name
• Blocks most “hard” credit inquiries
• Stops criminals from exploiting stolen personal information

What a freeze doesn’t do:

• Affect your credit score in any way
• Prevent you from using existing credit cards
• Stop you from checking your own credit reports
• Prevent all forms of identity theft (like tax fraud or medical identity theft)

The Three Credit Bureaus You Must Freeze

Here’s what many people don’t realize: there are three separate credit bureaus, and you must freeze each one individually. Freezing just one or two leaves gaps in your protection.

Equifax

One of the “Big Three” bureaus, and ironically the one responsible for the massive 2017 breach. Equifax maintains credit files on over 800 million consumers worldwide.

Experian

The largest credit bureau by some measures. Many credit card issuers (especially Chase) prefer pulling Experian.

TransUnion

The third major bureau. TransUnion is commonly pulled by Capital One and many retail creditors.

Don’t Forget These Secondary Bureaus

For comprehensive protection, also consider freezing these lesser-known bureaus:

Innovis - A fourth credit bureau that some lenders use ChexSystems - Tracks banking history (prevents fraudulent bank accounts) National Consumer Telecom & Utilities Exchange (NCTUE) - Used by utilities and telecom companies

Step-by-Step: How to Freeze Your Credit

Set aside 30-45 minutes to freeze all three major bureaus in one sitting. You’ll need:

• Your Social Security number
• Your date of birth
• Current and previous addresses
• A secure device and internet connection

Freezing Equifax

1. Go to equifax.com/personal/credit-report-services/credit-freeze/
2. Click “Place a Freeze” or “Get Started”
3. Create an account or log in if you have one
4. Verify your identity by answering security questions (questions about past addresses, employers, loan amounts)
5. Complete the freeze request
6. Save your PIN or confirmation number - you’ll need this to unfreeze later

Important: Equifax may try to upsell paid services. You don’t need them. The basic freeze is completely free.

Freezing Experian

1. Go to experian.com/freeze/center.html
2. Click “Add Security Freeze”
3. Create an Experian account or log in
4. Verify your identity through security questions
5. Complete the freeze request
6. Save your PIN and confirmation - Experian uses a PIN system for freezes

Watch out: Experian heavily promotes CreditWorks, their paid monitoring service. This is optional. The freeze itself costs nothing.

Freezing TransUnion

1. Go to transunion.com/credit-freeze
2. Click “Add Freeze”
3. Create a TrueIdentity account or log in
4. Verify your identity
5. Complete the freeze request
6. Save your login credentials - TransUnion uses account-based management rather than PINs

TransUnion’s interface is generally the most user-friendly of the three.

After Freezing: What to Expect

Once frozen, each bureau will send you confirmation (usually by email and/or mail). Keep these confirmations in a secure place along with:

• Your PIN for each bureau (if applicable)
• Your login credentials for each bureau’s website
• Confirmation numbers for each freeze

You’ll need these to unfreeze your credit later.

How to Unfreeze (Thaw) Your Credit

Freezing your credit doesn’t mean locking yourself out forever. When you need to apply for a new credit card, mortgage, or car loan, you’ll temporarily “thaw” your freeze.

Temporary vs. Permanent Unfreeze

Temporary thaw: You specify a date range (often 7-10 days) during which your credit is unfrozen. After that period, the freeze automatically reactivates. This is the recommended approach for most situations.

Permanent unfreeze: Completely removes the freeze until you manually refreeze. Use this if you’re in a period of active credit-seeking (like house hunting) and need ongoing access.

Unfreezing for Credit Card Applications

Here’s the typical workflow:

1. Decide which card you’re applying for
2. Research which bureau that issuer typically pulls (see the table below)
3. Log into that bureau’s website
4. Request a temporary thaw for 7-10 days
5. Wait for confirmation (usually instant to 1 hour)
6. Submit your credit card application
7. If you need reconsideration, you’re still in the thaw window

Which Bureau Does Each Issuer Pull?

This varies by state and changes over time, but general patterns:

Issuer	Primary Bureau
Chase	Experian (most states)
American Express	Experian
Capital One	All three (yes, all three)
Citi	Experian or Equifax
Discover	TransUnion or Experian
Bank of America	Experian or TransUnion
Wells Fargo	Experian
Barclays	TransUnion
US Bank	TransUnion or Experian

Capital One note: Capital One pulls all three bureaus for most applications. You’ll need to unfreeze all three when applying for their cards.

When in doubt: Unfreeze all three bureaus. It only takes a few extra minutes and ensures your application won’t be blocked.

Credit Freeze vs. Credit Lock: What’s the Difference?

The bureaus now offer both freezes and locks. Here’s how they differ:

Credit Freeze

• Free by federal law (since 2018)
• Regulated by state and federal law
• Requires PIN or password to lift
• Processing time: instant to 1 hour
• May require written request to lift (rare now)

Credit Lock

• Often requires paid subscription (bundled with monitoring)
• Offered as a convenience feature
• Typically faster to toggle on/off via app
• Less legal protection than a freeze
• Marketed as “premium” service

Our recommendation: Use the free credit freeze. The paid locks offer minimal advantages over freezes and are essentially a monetization strategy by the bureaus.

Credit Freeze FAQ for Credit Card Enthusiasts

If you actively apply for credit cards, you might wonder how freezing affects your strategy.

Will a freeze hurt my credit card applications?

Only if you forget to thaw it. Simply unfreeze the relevant bureau(s) before applying, and your application processes normally.

How long should I thaw for?

A 7-10 day window works well. This gives time for:

• Initial application processing
• Any verification calls from the issuer
• Reconsideration calls if initially denied

Can I thaw for one lender but stay frozen for others?

Not precisely, but here’s the workaround: only thaw the bureau your target lender uses. Other bureaus stay frozen, so applications to other lenders would still be blocked.

Does a freeze affect existing accounts?

No. Your current credit cards, loans, and accounts are unaffected. Issuers don’t need to pull a full credit report to manage existing accounts—they use soft pulls or your existing relationship.

Will I know if someone tries to access my frozen credit?

Usually not directly. The application simply fails on the lender’s end. However, you should regularly check your credit reports for unfamiliar accounts—a freeze isn’t 100% foolproof.

Building a Complete Identity Protection Strategy

A credit freeze is essential but shouldn’t be your only defense.

1. Check Your Credit Reports Regularly

Visit AnnualCreditReport.com to get free reports from all three bureaus annually. Look for:

• Accounts you don’t recognize
• Addresses you’ve never lived at
• Inquiries you didn’t authorize
• Incorrect personal information

2. Monitor Your Existing Accounts

Set up alerts on your credit cards and bank accounts for:

• Any transaction over a certain amount
• International purchases
• Card-not-present transactions
• Changes to account information

3. Use Strong, Unique Passwords

Each bureau account should have a unique, strong password. Consider a password manager to keep track of them all.

4. Enable Two-Factor Authentication

Wherever available, enable 2FA on your bureau accounts. This prevents criminals from unfreezing your credit even if they have your password.

5. Consider a Fraud Alert (Optional)

A fraud alert requires lenders to verify your identity before opening accounts. It’s less secure than a freeze but easier to manage. Fraud alerts last one year and can be renewed.

Managing Multiple Freezes: A Practical Workflow

Here’s how credit card enthusiasts typically manage their freezes:

Default State: Everything Frozen

Keep all three bureaus frozen at all times when you’re not actively applying for credit.

When Ready to Apply:

1. Research which bureau the issuer pulls
2. Log into that bureau’s website
3. Request a temporary 10-day thaw
4. Apply for the card
5. Handle any verification or reconsideration within the thaw window
6. Freeze automatically reactivates after 10 days

Keep Records

Maintain a simple spreadsheet or note with:

• Login credentials for each bureau
• PINs where applicable
• Dates of recent freezes/thaws
• Which bureau you thawed for which application

Key Takeaways

• A credit freeze blocks new credit accounts from being opened in your name—it’s the best defense against identity theft
• You must freeze all three bureaus (Equifax, Experian, TransUnion) separately for complete protection
• Freezes are completely free by federal law and don’t affect your credit score
• Use temporary thaws (7-10 days) when applying for credit cards or loans
• Research which bureau your target lender pulls, or thaw all three to be safe
• The paid “credit lock” products offer little advantage over free freezes
• Keep your PINs and login credentials in a secure place—you’ll need them to unfreeze

Frequently Asked Questions

Does freezing my credit affect my credit score?

No. A credit freeze has zero impact on your credit score. Your score is calculated based on your credit history, not whether your report is frozen.

How long does a credit freeze last?

Indefinitely. A freeze remains in place until you remove it. There’s no expiration or need to renew.

Can I still use my credit cards with a freeze in place?

Yes. A freeze only affects new account applications. Your existing credit cards work exactly the same.

What if I need credit urgently?

You can thaw your credit instantly online in most cases. Even if there’s a delay, it’s typically resolved within an hour. Plan ahead when possible, but urgent unfreezes are available.

Is freezing my credit enough to prevent all identity theft?

No. A freeze protects against new credit being opened in your name, but it doesn’t prevent tax identity theft, medical identity theft, or fraud on existing accounts. Use it as part of a broader security strategy.

Do I need to freeze my children’s credit?

Yes, if your children have SSNs, they can be targets for identity theft. Contact each bureau about freezing a minor’s credit—the process is different than adult freezes.

What happens if I lose my PIN?

Contact the bureau directly. They’ll verify your identity and help you reset your PIN or provide a new one. This can take several days, so keep your PINs safe.
