To prevent your identity from being stolen or further identity theft after your identity has already been stolen, you might consider freezing your credit report, a free service that all three major credit bureaus offer.

What Is a Credit Freeze?

A credit freeze, also known as a “security freeze,” locks your credit report, blocking all new inquiries. Since most banks require a credit check to process your application, an application for credit would likely be denied during a freeze. This makes it more difficult for identity thieves to open an account in your name. Consider placing a security freeze on your credit report if any of the following applies to you.

Your information has been exposed in a data breach. You’ve been a victim of identity theft. Your credit card number has been stolen. Your mail has been tampered with or stolen. You want to protect yourself from identity theft. Your credit monitoring service found your information on the dark web.

How Does a Credit Freeze Work?

While your security freeze is in place, new creditors and lenders can’t request your credit report. Instead, when you’re ready to apply for credit, you’ll need to temporarily lift the security freeze to allow a credit pull. You may not know ahead of time which credit report the company will check, so unfreezing all three credit reports is best.  If you’re requesting to lift the freeze online or over the phone, it will become effective within an hour. If you submit your request via mail, the freeze will be lifted within three business days of the bureau receiving your request. Credit bureaus are required to send you confirmation of the freeze within five business days of placing the freeze. However, the security freeze doesn’t keep everyone out of your credit file. Creditors and lenders that already have access to your accounts can access your credit report and score. Employers, insurance companies, and prospective landlords can still check your credit. Law enforcement agencies can also access your credit report and score despite a credit freeze.

How to Freeze Your Credit

You can freeze your credit report at all three major credit bureaus by contacting them individually. You’ll provide some personal information and select a series of security questions or a PIN for lifting or replacing the freeze in the future.

The Bottom Line

A credit freeze can help curb identity theft. However, be aware that a credit report freeze doesn’t offer protection from all types of fraud. Thieves may be able to open accounts with businesses that don’t use a major credit bureau. They may also be able to commit other types of fraud like taking over a credit card or bank account or filing taxes in your name.Businesses that you already have a relationship with will still be able to access your credit information, too, for credit reporting or raising your credit limit.
