A credit freeze and a credit lock both block new lenders from opening accounts in your name, but they're not the same product, and the protections they offer differ in important ways. If you're worried about identity theft or you've already been a victim, choosing the right tool — and knowing how to use it — can save you weeks of dispute work later.
Credit Freeze: The Legal Protection
A credit freeze is a federal right under the Fair Credit Reporting Act. Every consumer can place a freeze on their file at all three bureaus (Experian, Equifax, and TransUnion) for free, and the freeze must be respected by any lender pulling a credit report. When a freeze is in place, no new lender can open an account in your name without you temporarily lifting the freeze first.
Because it's a legal product, a credit freeze comes with strict rules. Bureaus must process freeze requests immediately when you submit them online or by phone (within one hour during business hours), and lifts must complete within an hour for online or phone requests, three business days for mail. The bureaus cannot charge for the service, and they cannot use your data while you're frozen.
A freeze does not affect your existing accounts, your credit score, your ability to use cards you already have, or your ability to pull your own credit report. It only blocks new credit applications.
Credit Lock: The Bureau's Product
A credit lock is a similar service, but it's a private product offered by the bureaus through their own apps. Equifax Lock, Experian CreditLock, and TransUnion TrueIdentity let you toggle access to your file with a single tap — much faster than the official freeze process. The trade-off is that locks are governed by terms of service rather than federal law, which means the bureau can change the rules, charge fees (some bureaus bundle locks into paid memberships), or terminate the service.
Most consumers should default to the free credit freeze. Use the lock product only if you frequently apply for new credit and need the convenience of one-tap toggling.
Combining Freezes With Monitoring
Freezing your credit doesn't tell you what's already happening. Pair a freeze with a monitoring service like Dovly (sign up for free) that alerts you to new tradelines, balance changes, address updates, and dark-web exposure of your personal information.
When to Use Each
Use a credit freeze if you've been the victim of identity theft, if your data was exposed in a breach, if you're a parent freezing a minor's file, or if you simply don't plan to apply for new credit for the foreseeable future. Use a credit lock if you apply for credit several times a year and you want a faster on-off switch — but understand the protection is contractual, not legal.
Key Takeaways
- Credit freezes are free, federally protected, and apply at all three bureaus.
- Credit locks are private bureau products with faster on-off toggling but weaker legal protection.
- A freeze plus monitoring covers most identity-theft scenarios — prevention plus detection.
- Default to the credit freeze; use the lock product only if convenience requirements clearly justify the trade-off.
When to Combine Tools
The strongest defense for most consumers in 2026 is a credit freeze at all three bureaus plus a free monitoring service that watches for breaches and unfamiliar inquiries. The freeze blocks the most common identity-theft scenario — fraudulent new accounts — while monitoring catches the things a freeze can't see, like dark-web exposure of your information or misuse of your existing accounts. Together they cost nothing and require less than 30 minutes to set up.

Frequently Asked Questions
Are credit freezes really free?
Yes. Federal law requires the bureaus to provide credit freezes and unfreezes free of charge. Anyone charging for a freeze is misrepresenting the service.
Can I still use my existing credit cards while frozen?
Yes. A credit freeze blocks new lenders from opening accounts in your name; it doesn't affect any account you already have. You can use existing cards, pay them, and update them normally.
Does a credit freeze affect my credit score?
No. Freezes have zero score impact — they're purely a defensive tool to prevent new accounts.
How fast can I lift a credit freeze?
Online and phone lifts complete within an hour. Mail lifts can take up to 3 business days. If you have a mortgage application coming up, plan to lift the freeze a week ahead.
