Credit Freeze vs. Credit Lock: How to Protect Your Credit Report
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.
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.
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.
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.
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.
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.
