A credit or security freeze is a quick way to protect yourself from identity theft and fraud. It basically locks down your credit so no one, including yourself, can open new credit accounts without your direct say-so. While it might sound like overkill when protecting your identity, it’s one of the smartest moves you can make. Plus, freezing your credit is totally free, doesn’t impact your credit score in any way, and you can easily thaw it with just a few clicks. If you want to know how it works and how to do it, keep reading the article.

A credit freeze restricts access to your credit report, making it nearly impossible for identity thieves to open new credit accounts in your name. When you apply for credit, the credit bureau (like Equifax, Experian, or TransUnion) typically shares your credit file with the creditor. But if your credit is frozen, the bureau won’t release your report, so the creditor can’t approve any new credit. Even if a stranger obtains your sensitive data like your Social Security number or birthdate, they won’t be able to use it to open new accounts.
A security freeze doesn’t affect your existing accounts, credit score, or current loans — plus, you can lift the freeze to apply for credit when you need to.
If you want to freeze your credit with all three bureaus (Equifax, Experian, and TransUnion), you’ll need to reach out to each one separately. You can do this online, over the phone, or by mail. If you choose the online or phone option, your credit may be frozen within one business day. But if you mail the bureaus a letter, it might take up to three business days to process the freeze.
Use the following contact information to freeze your credit with all three credit reporting agencies:

Freezing your credit is a good idea if you want to protect your identity and prevent strangers from opening fraudulent credit accounts in your name. It's a proactive, free way to keep your money and identity safe, so we recommend freezing your credit if you're not planning on taking out loans anytime soon.
A security freeze may also help minimize the damage if your data has been compromised in a data breach. Just contact all the credit bureaus as soon as possible, and rest easy knowing that no criminal will be able to take out a loan using your identity.
The only thing to remember is that you'll have to lift the freeze if you're looking to buy a new car, house, or phone. The seller will have to peek at your credit report to check your ability to pay. But don't worry — you can easily lift it through each credit bureau's website.
The purpose of a credit freeze is to restrict new creditor access to your credit report and prevent identity theft or fraud. However, it doesn't block the access completely — some entities can still check your credit report:
The difference between a credit freeze and a credit lock is that a credit freeze is a free service mandated by federal law, while a credit lock is something the credit bureaus offer, usually for a fee. See how they compare:
Credit freeze. A free service that blocks access to your credit reports and prevents criminals from opening new accounts in your name.
Credit lock. Usually a paid service that restricts access to your credit reports but easier to manage than a credit freeze.
Credit freeze. Free.
Credit lock. Some services may charge a fee.
Credit freeze. Requires contacting each credit bureau (Experian, Equifax, TransUnion) separately.
Credit lock. Can be activated via an app or website.

If you're planning a purchase for which you need credit or a loan, you'll have to lift your credit freeze first. Just like freezing your credit, you can thaw it permanently or temporarily by contacting the three major credit bureaus.
You can unfreeze your credit online, over the phone, or by mail. If you call the credit bureau, it will lift the freeze almost immediately. Online requests are usually processed within an hour, while a request via mail could take up to three business days.
A permanent thaw means that your credit stays unfrozen until you decide to freeze it again, while a temporary thaw lets you schedule when your credit should be accessible and when it should be frozen again. For example, you could schedule it to temporarily lift when you need to open that new credit line and have it freeze automatically a day or two later.
Besides freezing your credit, you can do a few other things to protect your credit report:
