A credit freeze is a federally regulated protection: it's free at all three bureaus, and by law lenders can't access your frozen report to open new credit in your name. A credit lock is a similar tool sold by the bureaus (often bundled with paid monitoring products) that works through an app but isn't governed by the same federal guarantees.
The practical differences
- Cost: freezes are always free; locks are sometimes free but often tied to a paid subscription.
- Speed: locks can typically toggle on and off instantly through an app; freezes may have a short processing window, though online freezes are usually fast too.
- Legal backing: freezes are protected under federal law (the Economic Growth, Regulatory Relief, and Consumer Protection Act); locks are governed by the bureau's own terms of service.
For most people, a freeze is the safer default
Since freezes are free and carry stronger legal protections, there's little reason to pay for a lock unless you specifically want the convenience of an all-in-one monitoring app.
When you'd actually need to lift it
You'll need to temporarily lift a freeze or lock whenever you apply for new credit — a mortgage, a car loan, a new credit card, or even some rental and utility applications that check credit. Each bureau lets you lift and reinstate it online, usually within minutes.
