Credit Freeze vs Credit Lock: What's the Real Difference?
Both stop new creditors from pulling your credit file, which stops most identity thieves from opening accounts in your name. The differences are in cost, convenience, and legal protection.
Side-by-Side
| Credit Freeze | Credit Lock | |
|---|---|---|
| Cost | Free (federal law) | Often a paid subscription or bundled perk |
| Legal basis | Statutory right under federal law | Contract with the bureau |
| Speed | Must be lifted within 1 hour online (by law) | Instant, app-based toggle |
| Setup | Separate PIN per bureau | Single app login |
| Protection strength | Stronger — legally mandated | Weaker — contractual |
How a Freeze Works
You contact each of the three bureaus separately — Experian, Equifax, and TransUnion. There is no single universal switch. Each issues you a PIN you'll need to thaw.
By law, an online freeze request must be honored quickly, and a thaw must be processed within about an hour during business hours. Freezing is free at all three bureaus, for everyone, regardless of whether you've been a fraud victim.
How a Lock Works
A lock is a bureau's own product. You toggle it on and off from your phone in seconds, which is genuinely convenient if you're applying for credit frequently. The trade-off is that it's a contractual feature, not a legal right — the terms can change, and it's often bundled into a paid monitoring subscription.
What Neither One Does
- Neither affects your credit score. Freezing does not lower or raise it.
- Neither blocks your existing accounts. Your current cards and loans keep working, and creditors can still report activity.
- Neither prevents all fraud. Existing-account takeover, tax-refund fraud, and benefits fraud don't require a credit check at all.
- Neither stops prescreened offers unless you separately opt out.
What to Do
If you're not applying for credit soon: freeze all three files. It costs nothing, it's the strongest protection available, and it's the single highest-leverage 20 minutes in personal-finance security.
If you apply for credit often: a lock's convenience may justify its cost — but a freeze you manage with stored PINs costs nothing and takes about a minute per bureau to lift.
If you already have reason to believe you've been compromised: freeze all three, then review your reports line by line. If you find accounts you don't recognize, our guide to disputing credit report errors walks through the process.
Freeze the files you aren't using. Keep the PINs somewhere you'll actually find them — most people's only real problem with freezing is losing the PIN at the worst possible moment.
