A credit freeze — also called a security freeze — is one of the most effective ways to protect yourself from identity theft. It blocks lenders from accessing your credit report, making it nearly impossible for someone to open new credit accounts in your name. It is free, reversible, and takes about 15 minutes to set up.
How a Credit Freeze Works
When you freeze your credit, the three major bureaus (Equifax, Experian, TransUnion) lock access to your file. When someone applies for credit using your information, the lender pulls your report — but if the file is frozen, the pull is blocked and the application is rejected. No report access, no new account.
A freeze does not affect your existing accounts, your credit score, or your ability to get free credit reports. It only prevents new inquiries for new credit applications.
Credit Freeze vs. Fraud Alert
A fraud alert tells lenders to take extra steps to verify your identity before approving credit in your name. It is weaker than a freeze — lenders can still pull your report. An initial fraud alert lasts one year. An extended alert (for confirmed identity theft victims) lasts seven years. A freeze is more protective because it blocks access entirely.
How to Place a Credit Freeze
You must freeze your report at each bureau separately. There is no single system that freezes all three at once.
Equifax
Visit equifax.com/personal/credit-report-services/credit-freeze/ or call 1-800-685-1111. You can also mail a written request.
Experian
Visit experian.com/freeze/center.html or call 1-888-397-3742.
TransUnion
Visit transunion.com/credit-freeze or call 1-888-909-8872.
You will create an account at each bureau and receive a PIN or confirmation code. Store these safely — you will need them to temporarily lift the freeze when you apply for credit.
How to Temporarily Lift a Credit Freeze
When you need to apply for a loan, credit card, or mortgage, you lift the freeze temporarily. You can do this online in most cases and it typically takes effect within an hour. Tell the lender which bureau they pull from (or lift all three), apply for credit, then re-freeze once approved.
You can set an automatic expiration date when you lift the freeze — for example, lift it for five days, then it re-freezes automatically. This is more secure than lifting it indefinitely.
Who Should Place a Credit Freeze?
A credit freeze makes sense if:
- Your personal information was exposed in a data breach
- Your Social Security number was stolen or compromised
- You do not plan to apply for new credit in the near future
- You want maximum protection against identity theft as a baseline measure
It is less convenient if you frequently apply for new credit cards or loans, since you need to remember to lift the freeze each time. But for most people who are not actively seeking new credit, a freeze is a low-effort, high-protection tool.
How to Freeze Your Child’s Credit
Children under 16 can have their credit frozen by a parent or guardian. Since children typically have no credit file, you may need to request the bureau create one and immediately freeze it. This protects against child identity theft, which is a real and underreported problem. The process varies slightly by bureau — each has a child freeze request form.
Does a Credit Freeze Hurt Your Credit Score?
No. A credit freeze does not affect your credit score in any way. It does not show up as a negative item. It does not reduce the age of your accounts. It is entirely neutral on your score.
Other Ways to Protect Your Identity
A credit freeze covers new credit applications. For broader protection:
- Check your credit reports regularly at AnnualCreditReport.com
- Enable two-factor authentication on financial accounts
- Use unique, strong passwords for every financial account
- Monitor your bank statements for unauthorized charges
- Consider signing up for an identity monitoring service if you have been in a major data breach
Bottom Line
A credit freeze is free, reversible, and takes 15 minutes to set up across all three bureaus. If you are not actively applying for new credit, placing a freeze is one of the most effective steps you can take to prevent identity theft. Lift it when you need to apply for something, then re-freeze. It costs nothing and protects your financial identity.
