Credit Freeze vs. Credit Lock: How to Protect Your Credit Report
By DebtCalculators Team · Last reviewed September 4, 2026
A credit freeze is free, legally mandated, and the strongest protection against identity theft — it blocks new credit accounts from being opened in your name until you lift it. Freezing your credit at all three bureaus (Equifax, Experian, TransUnion) takes about 30 minutes and costs nothing, and it doesn't hurt your score or block existing accounts.
What a Credit Freeze Does
A credit freeze (also called a security freeze) restricts access to your credit report so lenders can't view it, which means they typically won't open new accounts in your name. Identity thieves can't get credit cards, loans, or utilities using your identity while the freeze is active. It's free by federal law, doesn't affect your credit score, and doesn't stop you from using existing credit cards or paying existing loans.
A freeze is selective rather than absolute. Companies you already have accounts with can generally still review your file for account management and collection purposes, and government agencies may access it for specified purposes. It also blocks new-account fraud only, not misuse of accounts you already hold, so a thief with your card number can still attempt charges. Think of it as one layer: the freeze stops someone opening a loan in your name, while monitoring and statement review catch everything else.
Freeze at All Three Bureaus
Because lenders check only one bureau, you must freeze your credit at all three — Equifax, Experian, and TransUnion — separately. Each bureau gives you a PIN or password for unfreezing. The process is online and takes about 10 minutes per bureau; you'll need to verify your identity with your Social Security number, name, address, and date of birth. Consider freezing a child's credit too, since children are prime identity-theft targets.
You do not have to be a victim to freeze. Anyone can place one at any time, and the bureaus cannot charge you for placing, lifting, or removing it. Keep the PINs or passwords somewhere you will find them years later, because a lost credential means proving your identity again, which can be slow. It is also worth knowing that the three major bureaus are not the only consumer reporting agencies; smaller ones track things like deposit accounts and rental history, and their procedures and coverage differ.
Credit Freeze vs. Credit Lock
A freeze is required by law to be free, and its terms are standardized across bureaus. A lock is a commercial feature offered by each bureau — often free but sometimes bundled into paid subscriptions — and uses a toggle in the bureau's app. Locks are more convenient to pause but are governed by the bureau's terms, not federal law, so the protections can differ. For maximum safety at zero cost, a freeze is the stronger choice.
The practical difference is who can change the rules. Freeze procedures are set by federal law, so the bureaus must honor your request and cannot alter the terms unilaterally. A lock is a service governed by each bureau's own agreement, which means features and availability can change, and in some cases it is bundled with a paid monitoring product. Functionally both block new credit, so the choice comes down to whether you want the legal guarantee or the convenience of an app toggle.
When You Need to Lift the Freeze
You must lift a freeze before applying for credit: a mortgage, auto loan, new credit card, rental application, insurance quote, or even a new cell phone plan. Each bureau lets you lift it temporarily (e.g., for 14 days) or permanently, with the PIN you created. The lift is usually instant online or by phone, and some bureaus let you specify an exact end date so you don't have to remember to refreeze.
Plan for more than the credit application itself. Landlords, insurers, utilities, and mobile carriers may also check your file, so a freeze can stall a lease or a new phone plan if you forget. When you are rate shopping for a mortgage or auto loan, ask each lender which bureau it pulls, since a tri-merge report means all three frozen files must be opened. A temporary thaw with an end date is usually safer than unfreezing indefinitely, because it refreezes itself automatically.
What a Freeze Does NOT Do
A freeze protects against NEW accounts, but it does not protect your existing accounts, won't stop someone from using a stolen credit card number, and doesn't block fraudulent charges on accounts you already have. For that, monitor statements, set up transaction alerts, and consider a fraud alert (which requires lenders to verify identity) alongside the freeze. The freeze is the baseline; monitoring is the complement.
Several kinds of identity theft happen entirely outside the credit system. A freeze will not stop a fraudulent tax return filed in your name, a thief opening a bank account using your information, or medical services billed under your insurance, so the IRS, your bank, and your health insurer each have their own protections worth setting up. It also does not end prescreened credit offers, which you stop separately through the nationwide opt-out. And it never removes your data from the bureaus; it only controls who can see it.
Frequently Asked Questions
Does a credit freeze cost money?
No. Credit freezes are free by federal law at all three major bureaus — Equifax, Experian, and TransUnion. Lifting or removing a freeze is also free. The law that made this possible (the Fair and Accurate Credit Transactions Act) requires each bureau to honor freeze requests at no charge.
Does freezing my credit hurt my credit score?
No. A credit freeze has zero effect on your credit score. It simply blocks new lenders from pulling your credit file. Your existing accounts, payment history, and utilization all continue to report normally, and your score is computed the same way.
How do I freeze my credit at all three bureaus?
Visit each bureau's website separately — Equifax, Experian, and TransUnion — and request a freeze in their online security center. Verify your identity, create a PIN or password, and confirm. The whole process takes about 30 minutes total and is free. You'll use the PIN later to lift the freeze when applying for credit.
How long does a credit freeze last?
A credit freeze stays in place indefinitely until you lift it. There's no expiration. When you apply for new credit, you lift the freeze temporarily or permanently using the PIN from each bureau — then you can refreeze immediately after the credit check completes.
