What Does Freezing Your Credit Do and How It Works

Freezing your credit tells the three major credit bureaus to lock your credit file so that most lenders and other new creditors cannot pull it. With the file locked, someone trying to open a credit card, loan, or financing account in your name gets turned away when the lender’s credit check comes back blocked. The freeze is free at Equifax, Experian, and TransUnion, stays in place until you lift it, and has no effect on your credit score.¹

What a Freeze Blocks

The mechanics are simple. Opening a new credit account almost always requires the lender to check your credit report. If your file is frozen, that check comes back denied, and the application dies there. That single choke point is why a freeze is the strongest everyday protection against new-account identity theft.²

The same wall blocks you. When you apply for a mortgage, auto loan, new credit card, or an apartment that runs a credit check, you have to lift the freeze first. That inconvenience is the whole trade. Lifting takes under an hour online, and you can refreeze right afterward.

What a Freeze Does Not Do to Your Score

Placing, lifting, or removing a freeze has zero effect on your FICO or VantageScore. Your existing credit cards, loans, and other accounts keep reporting payment history to the bureaus as usual, and your score keeps updating in the background. The freeze controls who can look at your file, not what is in it.¹

Who Can Still See Your File

A freeze is not a total blackout. Federal law carves out several categories of access, and a few of them catch people off guard.

Your existing creditors keep looking at your file for account review, credit-line changes, and monitoring. If one of those accounts is sold or assigned, the new holder inherits that access. Debt collectors working an existing debt can pull your report too.³

Government agencies have broad exemptions. Federal, state, and local agencies can access your file under a court order, warrant, or subpoena, and so can agencies investigating fraud, collecting delinquent taxes, or enforcing child support.³

Three more exceptions surprise people. Insurance companies underwriting a policy can see through the freeze. Employers and landlords running background or tenant screens can too. And any company verifying your identity for a non-credit purpose, such as opening a bank account or confirming you during a fraud investigation, has access.³

You keep access to your own file at any time, and any credit-monitoring service you’ve signed up for keeps working.

Prescreened Credit Card Offers Still Come

A freeze does not stop those “pre-approved” offers in the mail. Those come from a separate marketing-list process the freeze doesn’t touch. To shut them off, opt out through optoutprescreen.com or 1-888-567-8688. You can opt out for five years online or by phone, or permanently by signing and returning the form the bureaus will send you. The opt-out covers bureau-generated lists only; companies you already do business with, and lists sourced elsewhere, can still reach you.⁴

How to Place the Freeze

This is the step most people get partly wrong: you must freeze at each of the three bureaus separately. Equifax, Experian, and TransUnion run separate databases, and freezing one does nothing to the others. If you freeze only Experian and the lender pulls TransUnion, your file is wide open.²

Each bureau accepts freeze requests online, by phone, or by mail. Online is fastest and confirms immediately:

Equifax: create a myEquifax account at equifax.com and freeze from the dashboard.⁵
Experian: use the security freeze portal at experian.com/freeze.⁶
TransUnion: go to transunion.com/credit-freeze.⁷

You’ll verify your identity with your name, Social Security number, date of birth, and recent addresses. Some bureaus issue a PIN during setup; others verify you with personal information when you come back to make changes. Save whatever credential the bureau gives you.

Federal law gives the bureaus one business day to place a freeze requested online or by phone, and three business days for a mailed request.³ You should get a confirmation showing the effective date; if any detail looks wrong, call the bureau to fix it.

Lifting the Freeze When You Need Credit

You have two ways to open the file back up. A temporary lift (sometimes called a thaw) opens it for a set window and then the freeze snaps back automatically. A permanent removal takes the freeze off entirely. Both require your PIN or password and identity verification.

Before you lift, ask the lender which bureau they plan to pull from. You can often lift at just that one bureau and leave the other two locked.²

The timeline for lifts is tight. When you request a lift or removal online or by phone, the bureau must act within one hour.³ That is what makes a freeze workable in everyday life. You can apply for a mortgage in the morning and refreeze by lunch.

How a Freeze Differs From a Fraud Alert or a Credit Lock

These three tools get confused all the time, and the differences matter.

Fraud Alert

A fraud alert does not block access to your file. It flags the file so that lenders are supposed to take extra steps to verify your identity before approving new credit. An initial fraud alert lasts one year and can be renewed. You only contact one bureau, which is required to notify the other two.²

If you’ve already been a victim of identity theft, you can place an extended fraud alert that lasts seven years, after filing an identity theft report at IdentityTheft.gov or a police report.² Deployed active-duty service members can place an active-duty alert that lasts twelve months and also removes their name from prescreened offer lists for two years.⁸

Credit Lock

A lock blocks access the way a freeze does, but it’s a product the bureau offers under a private contract rather than a right under federal law. That changes your legal footing if something goes wrong: a freeze is governed by federal and state consumer-protection statutes, while a lock is governed by the bureau’s terms of service, which often include arbitration clauses. Some locks are free; others are bundled into paid monitoring subscriptions. The usual selling point is convenience, since most locks toggle through a mobile app with no PIN.

Freezing a Child’s or Incapacitated Adult’s Credit

Children are heavy identity theft targets because no one checks their credit for years. Federal law lets a parent or legal guardian freeze the credit of anyone under 16. If the child has no credit file yet, which most don’t, the bureau is required to create one just so it can be frozen. That created file cannot be used for credit purposes.⁹ You’ll submit proof of the child’s identity and your authority as a parent or guardian, usually by mail or through dedicated forms rather than the standard online portals.

For an incapacitated adult, a guardian, conservator, or holder of a valid power of attorney can request a freeze with proof of the adult’s identity, proof of the requester’s identity, and documentation of legal authority. Equifax, for instance, uses a specific Incapacitated Adult Freeze Request form.¹⁰
