A credit freeze is widely considered the single most effective tool for preventing new-account identity theft, and it’s completely free — yet many people have never set one up, often because they’re not sure exactly what it does or how to get started. This guide walks through both.
What a Credit Freeze Actually Does
A credit freeze restricts access to your credit report, which means lenders, credit card companies, and other businesses cannot view your credit file to approve a new account. Since almost all new credit applications require a lender to check your credit report first, freezing that access effectively blocks anyone — including a scammer with your Social Security number — from opening new credit in your name.
Importantly, a credit freeze does not affect your existing accounts. You can still use your current credit cards, pay bills, and make purchases as normal — the freeze only blocks new credit applications from going through.

Freeze vs. Fraud Alert vs. Credit Lock: What’s the Difference?
Credit freeze — a federally regulated, free protection blocking new account access at all three bureaus. The strongest option, and what’s recommended if your info’s been exposed in a breach or you suspect identity theft.
Fraud alert — a lighter measure asking lenders to take extra verification steps before approving credit, but not blocking access outright. Free, faster to set up (placing it with one bureau notifies the other two), but weaker protection than a full freeze.
Credit lock — sounds similar, but it’s a different product, usually a paid, private service from a credit bureau or monitoring company. Works similarly to a freeze, but without the same federal legal backing — so a true credit freeze is generally the more reliable pick.
Is a Credit Freeze Free?
Yes. Federal law makes placing, lifting, and removing a credit freeze free at all three bureaus, for everyone — no exceptions, no subscription. Be wary of anything charging a recurring fee for something called a “credit freeze” — that’s probably the paid “lock” product wearing different branding.
How to Freeze Your Credit: Step by Step
You’ll need to freeze your credit separately at each of the three bureaus — freezing one doesn’t freeze the others.
Equifax
- Online: equifax.com, create or log into a myEquifax account, place the freeze
- Phone: 1-888-298-0045
Experian
- Online: experian.com Freeze Center — look specifically for the free “security freeze” option, not the paid “CreditLock” product Experian sometimes pushes first
- Phone: 1-888-397-3742
TransUnion
- Online: TransUnion’s Freeze Center, or “Add Freeze” if you already have an account
- Phone: 1-888-909-8872
Have your Social Security number, birthdate, current address, and sometimes previous addresses ready to verify identity for each. Doing all three online usually takes 15-30 minutes total, and freezes kick in immediately.
Save your login credentials or PIN for each bureau — you’ll need them later to temporarily lift the freeze whenever you actually want to apply for credit.
When You’ll Need to Temporarily Lift It
Applying for a new credit card, loan, mortgage, or even some apartment rentals or new utility accounts means the lender needs to check your credit — so you’ll need to temporarily lift the freeze at whichever bureau they use beforehand. This usually takes a few minutes online or by phone, and can either reactivate automatically after a set window or get manually reinstated once your application’s done.
The Bottom Line
A credit freeze is a free, powerful, genuinely underused tool that blocks new-account identity theft right at the source, no matter what personal information a scammer might already have. Setting it up across all three bureaus takes under an hour, doesn’t touch your existing accounts or credit score, and can be temporarily lifted whenever you actually need new credit — making it one of the highest-value, lowest-effort protections out there.
