A credit lock is a tool from a credit bureau that blocks most new lenders from viewing your credit report until you unlock it, usually with a tap in an app. It works much like a credit freeze, but a freeze is free and backed by federal law, while a lock is a bureau product governed by its own terms.
Key Takeaways
A credit lock restricts access to your credit report, which helps prevent new credit accounts from being opened in your name.
Unlike a credit freeze, a lock is a product offered by each credit bureau. Pricing and features vary by bureau, so check with each one, and most let you lock and unlock through an app.
A credit freeze is free by federal law and can be lifted within an hour when you request it online or by phone, so it’s nearly as fast as a lock.
Locks are governed by each bureau’s user agreement, not the federal freeze law. You need to lock or freeze with all three bureaus for full coverage.
The main purpose of a credit lock is to prevent identity theft. If a fraudster gets your personal information and applies for credit, the lender usually can’t pull your report, so the application will likely be denied. When you want to apply for credit yourself, you unlock your report, then lock it again afterward.
A lock doesn’t block everyone. Your existing creditors can still review your account, and soft inquiries, such as checking your own credit, still go through. A lock also doesn’t stop fraud on accounts you already have, so keep reviewing your statements and reports.
What’s the Difference Between a Credit Lock and a Credit Freeze?
Both restrict access to your credit report, but they work differently.
A credit freeze, also called a security freeze, is a right under federal law. Each bureau must place a freeze within one business day of an online or phone request and lift it within one hour. You manage it with each bureau separately, often with a PIN or online account. A credit lock is a product the bureaus offer, designed for convenience, with locking and unlocking through an app or website.
Here’s a quick comparison:
Control: A lock usually switches on and off instantly in an app. A freeze is placed and lifted by request, which is fast online or by phone but takes a few more steps.
Cost: Placing and lifting a freeze is free by law. Lock pricing and features vary by bureau and can change, so check with each bureau.
Legal protection: Freezes are governed by federal law. Locks are governed by the terms of your agreement with each bureau, so read those terms before you sign up.
Convenience: If you apply for credit often or want to switch access on and off quickly, a lock may be easier to manage.
What About a Fraud Alert?
A fraud alert is a third option. It doesn’t block access to your report, but it tells lenders to take extra steps to verify your identity before opening an account. An initial fraud alert is free and lasts one year, and you only need to contact one bureau, which must notify the other two. Identity theft victims can get an extended fraud alert that lasts seven years.
How Do You Lock Your Credit With Each Bureau?
The three major credit bureaus don’t share lock information, so you have to lock your report with each one separately for full coverage.
Create an account and verify your identity. You’ll usually give your name, address, date of birth and Social Security number.
Lock your report. Once you’re signed up, you can typically lock or unlock with a single click or tap in the bureau’s app or website.
Unlock before you apply for credit. Ask the lender which bureau it uses, unlock that report (or all three), then lock again once the application is done.
How Much Does a Credit Lock Cost?
It depends on the bureau. Pricing and features vary and can change, so check with each bureau before you sign up.
If cost is a concern, a credit freeze gives similar protection for free at all three bureaus. You can learn more about getting all three of your credit reports to check for accounts you don’t recognize.
It depends on what you need. A lock may suit you if you want app-based, on-and-off control and you apply for credit often. A freeze is free, backed by federal law and can be lifted within an hour online or by phone, which makes it a strong choice for most people who want long-term protection.
No. Locking or unlocking your credit has no effect on your credit score. It only controls who can access your report and doesn’t change the information on it. Checking your own credit doesn’t hurt your score either; see does your credit score drop when you check it.
Yes. A credit lock blocks most new credit applications from accessing your report. It doesn’t affect your existing accounts, so you can keep using your cards and making payments as usual.
Yes, for full coverage. Equifax, Experian and TransUnion don’t share lock or freeze information, and a lender may pull from any of them. A lock at one bureau leaves your reports at the other two open.
Act right away. Consider placing a credit freeze or lock with each bureau, and think about an extended fraud alert. Report the theft to the FTC at IdentityTheft.gov, contact the police if needed, and review your credit reports for fraudulent accounts.

Should You Lock or Freeze Your Credit?
Whether you pick the convenience of a lock or the free, federally protected freeze, controlling who can see your credit report is a smart move, especially after a data breach.
