Freezing your credit is one of the most effective and inexpensive ways to lessen the risks of identity theft. When you freeze your credit, no one can even look at your credit file, making it next-to-impossible for anyone else to open a new account in your name.
The downside is that you won't be able to open a new account either. So all three major credit bureaus — Equifax, Experian and TransUnion — let you easily "unfreeze" your credit files, either temporarily or permanently. (You can set the dates and duration of a temporary freeze.)
Freezing and unfreezing your credit is free across the United States, thanks to a federal law that took effect in September 2018, one year after a massive Equifax data breach.
Perhaps fittingly, Equifax gives you the most bang for your (free) buck of all three credit bureaus when you set up a credit freeze.
You'll have to create an Equifax account, but this comes with a "dashboard" on the Equifax website that gives you monthly credit scores and a summary of your Equifax credit report and also lets you set up a fraud alert. You can even start a dispute over inaccurate information in your credit file.
Equifax also offers a free service called "Lock & Report" that is basically the same as a credit freeze, except that there are mobile apps for iOS and Android that let you "unlock" your Equifax credit file with a swipe of a finger. To do this with a credit freeze, you have to log into your account on the Equifax website.
The difference is that Lock & Report isn't regulated by the federal government, and Equifax makes more money if it's easier to unlock your files. Equifax doesn't let you have a credit lock and a credit freeze at the same time.
Below is how to set up an Equifax credit freeze. We also have guides on how to freeze your credit with Experian and how to freeze your credit with TransUnion.

This is the easiest way to freeze your credit with Equifax. Go to the dedicated page on the Equifax website at https://www.equifax.com/personal/credit-report-services/credit-freeze/ (opens in new tab) and click "Get started with a freeze."
Then you'll have to fill out personal information, including your name, address, date of birth and Social Security number. Equifax will retrieve your information and prompt you to set up an Equifax account. Make sure the password is unique and strong.
