Credit Freeze vs. Fraud Alert vs. Credit Lock

The short answer

A credit freeze is generally the strongest free tool for blocking new-account credit access. A fraud alert tells lenders to take extra steps to verify your identity before extending new credit. A credit lock is a credit-bureau product governed by the provider's agreement rather than the same statutory freeze protections.

The Consumer Financial Protection Bureau notes that security freezes are free and protected by law, while credit locks may be bundled with paid services and are not more effective than a security freeze.

Credit freeze

A credit freeze, also called a security freeze, restricts prospective creditors from accessing your credit file.

Because lenders usually need access to a credit report before opening a new account, a freeze can make it much harder for an identity thief to obtain new credit in your name.

Key features:

• free to place and lift;
• available even if identity theft has not already occurred;
• does not affect your credit score;
• stays in place until you remove it;
• generally must be placed separately with Equifax, Experian, and TransUnion.

When you legitimately apply for new credit, you can temporarily lift the freeze.

Fraud alert

A fraud alert does not block access to your credit file. Instead, it tells businesses that they should verify your identity before opening new credit.

The FTC says an initial fraud alert is free and generally lasts one year. You can place an initial alert by contacting one of the three nationwide credit bureaus; that bureau must notify the other two.

An extended fraud alert may be available after identity theft and lasts longer.

A fraud alert can be useful when you suspect misuse but do not want to restrict credit-report access as fully as a freeze.

Credit lock

A credit lock can also restrict access to a credit file, but it is a commercial product offered by a credit reporting company.

The CFPB specifically distinguishes locks from freezes: a lock is based on the provider's service terms, may be bundled with other paid services, and does not provide greater protection than the free security freeze available by law.

That does not mean a lock is useless. Some consumers may prefer the convenience of a bureau's app or interface. But compare the contract, cost, and cancellation terms before paying for a product when a statutory freeze is available for free.

Side-by-side comparison

| Tool | Main purpose | Cost | How long it lasts | Setup |

| --- | --- | --- | --- | --- |

| Credit freeze | Restrict access to file to help block new accounts | Free | Until lifted | Contact each bureau |

| Fraud alert | Tell creditors to verify identity | Free | Initial alert generally one year | Contact one bureau; it notifies the others |

| Credit lock | Commercial restriction on file access | Varies by provider/product | Depends on agreement | Usually managed through bureau service/app |

Which one may fit your situation?

A freeze is often the strongest choice when:

• your Social Security number or sensitive identity data was exposed;
• someone already opened accounts in your name;
• you want strong preventive protection even without known fraud;
• you do not expect to apply for credit frequently.

A fraud alert may fit when:

• you want added identity verification without fully restricting file access;
• you suspect possible identity theft;
• you want one request to reach all three bureaus for the alert.

A credit lock may appeal for convenience, but compare it with the free freeze before paying for ongoing access or monitoring features.

What these tools do not do

None of these tools replaces ongoing monitoring of existing accounts.

A freeze does not stop someone who already has access to an existing credit card or bank account from attempting unauthorized transactions. Continue reviewing statements and alerts for accounts you already have.

If information on your credit report is inaccurate, a freeze also does not correct it. See How to Dispute Credit Report Errors.

If identity theft has already happened

In addition to freezing credit or placing an alert, report identity theft through the FTC's IdentityTheft.gov process and follow the recovery steps that apply to your situation.

Then review all three credit reports for accounts, inquiries, addresses, or balances you do not recognize. Our How to Read a Credit Report guide can help organize that review.
