Credit Freeze vs. Credit Lock
They sound interchangeable, and they do the same basic job — but one is free and protected by federal law, while the other is a bureau product that may cost money and comes with weaker guarantees. Here's the difference, and which one most people should choose.
A credit freeze is free, federally mandated under the Fair Credit Reporting Act, and available at all three bureaus. A credit lock is a bureau product that does the same job but is governed by terms of service instead of law, and may carry a monthly fee. Neither affects your credit score. For most people, a freeze is the better default.
What they have in common
Both a credit freeze and a credit lock restrict access to your credit report. When either is active, lenders can't pull your file — which means someone pretending to be you can't open a new account or loan in your name, because the lender's check comes back blocked.
Both also leave your existing accounts untouched, and crucially, neither one affects your credit score. They control who can see your file; they don't change what's in it.
Where they differ
| Factor | Credit Freeze | Credit Lock |
|---|---|---|
| Cost | Always free, by law | Sometimes free, sometimes a monthly fee depending on the bureau and tier |
| Legal protection | Governed by federal law (FCRA), with legal recourse if violated | Governed by the bureau's terms of service, which they can change |
| Speed to lift | Can take minutes to a few hours, depending on the bureau | Often instant via a mobile app |
| Bundled features | None — it's a single function | Sometimes bundled with credit monitoring or identity protection |
| Effect on credit score | None | None |
The cost difference can be significant. According to recent reporting, Experian's credit lock is offered as part of a premium subscription that runs around $24.99 per month, while Equifax offers its Lock & Alert feature for free. A freeze, by contrast, is free at every bureau, every time, because federal law requires it.
"A freeze is a legal right. A lock is a product. Both block fraud — but only one of them is something a company can decide to start charging you for."
Why the legal distinction matters
This is the part that's easy to overlook. A credit freeze is protected by the Fair Credit Reporting Act, which means the bureaus are legally required to offer it for free and follow specific rules about placing and lifting it. If something goes wrong, you have legal recourse.
A credit lock is a contractual agreement governed by the bureau's terms of service. Those terms can include arbitration clauses and can be changed by the bureau. Consumer advocates generally point out that a protection guaranteed by law is stronger than one guaranteed only by a contract that the other party wrote and can revise.
How to freeze your credit
So which should you choose?
For most people, the answer is straightforward: freeze first. It's free, it's backed by law, and it provides strong protection. The only real tradeoff is a small amount of friction when you need to apply for credit — and for most people, that's rare enough not to matter.
A credit lock makes more sense for someone who applies for new credit frequently and genuinely values the convenience of toggling access instantly from an app — and who doesn't mind paying for it, or accepts the weaker legal footing. For most people, that convenience isn't worth the cost or the tradeoff.
This is exactly the kind of quietly important decision that's easy to put off indefinitely — there's no deadline forcing it, so it sits on the someday list until a breach or a fraud scare makes it suddenly urgent. Knowing the difference ahead of time means you can act calmly rather than reactively.
Frequently asked questions
What is the difference between a credit freeze and a credit lock?
A credit freeze is a free, federally mandated restriction governed by the Fair Credit Reporting Act. A credit lock does the same basic job but is governed by the bureau's terms of service and may carry a monthly fee. Both block access to your credit report to help prevent new-account fraud.
Is a credit freeze free?
Yes. By federal law, credit freezes are free to place and free to lift at all three major bureaus — Equifax, Experian, and TransUnion. You should never be charged to freeze or unfreeze your credit.
Does freezing your credit hurt your credit score?
No. Neither a credit freeze nor a credit lock affects your credit score. They only restrict who can access your credit report; they don't change the information in it.
Should I choose a credit freeze or a credit lock?
For most people, a freeze is the better default: free, backed by federal law, strong protection. A lock may appeal to people who apply for credit often and value instant app-based convenience, and who don't mind a possible fee and weaker legal protections.
Do I need to freeze my credit at all three bureaus?
Yes, to be fully protected. Each bureau maintains its own file, so freeze with Equifax, Experian, and TransUnion separately. A freeze at only one bureau leaves the other two accessible.
