What Is a Credit Freeze and How Does It Work

A credit freeze is a tool that lets you restrict access to your credit report. When you place a freeze with the three major credit bureaus—Equifax, Experian, and TransUnion—these companies cannot share your credit information with potential lenders, creditors, or other businesses without your permission.

Here's how it works in practice: When someone applies for a credit card, car loan, mortgage, or even opens a utility account, the lender typically requests your credit report from one or more of these bureaus. The lender uses this information to decide whether to approve the application and what interest rate to offer. A credit freeze acts as a barrier between your report and these requests. Without your consent, the lender cannot see your credit history, which makes it nearly impossible for them to complete a credit application in your name.

The freeze itself comes in different levels of restriction. A full freeze blocks all access to your credit report. Some bureaus also offer a "fraud alert," which is less restrictive—lenders can still see your report, but the alert notifies them to take extra steps to verify your identity before approving credit. The freeze is particularly useful if you've experienced identity theft, received suspicious credit offers, or simply want to reduce unwanted credit solicitations.

One important detail: a credit freeze does not affect your existing accounts. If you already have a credit card, mortgage, or loan, your current creditors can still review and manage your account. The freeze only prevents new inquiries from businesses trying to access your report for new credit decisions.

The freeze also does not impact your credit score directly. Your score is calculated based on your payment history, amounts owed, length of credit history, and other factors. A freeze doesn't change these underlying elements. However, because lenders cannot see your report, they cannot approve new credit applications while the freeze is active.

Practical takeaway: Understand that a credit freeze is a blocking mechanism, not a monitoring service. It stops new credit inquiries but doesn't monitor your accounts or alert you to suspicious activity—those are separate services.

Why You Might Consider Placing a Credit Freeze

There are several reasons someone might decide to use a credit freeze. The most common reason is protection against identity theft. According to the Federal Trade Commission, over 4.6 million cases of identity theft were reported in 2023 in the United States. When criminals obtain your personal information—such as your Social Security number, name, and address—they may try to open accounts in your name. With a credit freeze in place, fraudsters cannot open new credit accounts even if they have your personal data, because lenders will be blocked from accessing your credit report.

Another reason to freeze your credit is to reduce unwanted credit offers and solicitations. Credit bureaus sell prescreened lists to creditors and marketers. When you place a freeze, you reduce the likelihood that your information will be sold for marketing purposes. This can significantly decrease the volume of credit card offers, personal loan solicitations, and other marketing mail you receive.

Some people use a freeze as a preventive measure even if they haven't experienced fraud. This is called a "security freeze." Since freezing is free and relatively simple to set up, some consumers view it as basic financial hygiene—similar to locking your front door. They want to know that if their information becomes compromised in a data breach, the freeze provides an extra layer of protection.

Additionally, if you're not planning to apply for credit in the near future, a freeze eliminates a risk vector with no downside. Young people who don't need loans, retirees who won't be borrowing money, or anyone in a stable financial situation may place a freeze to reduce exposure.

A freeze is also useful if you suspect you've been a victim of fraud. If you've noticed unfamiliar accounts on your credit report, received bills for accounts you didn't open, or learned that your information was included in a data breach, a freeze can prevent the criminal from opening additional accounts while you work on resolving the fraud.

Practical takeaway: A credit freeze is most valuable if you don't plan to apply for new credit soon, have experienced or are concerned about identity theft, or want to reduce marketing solicitations.

Understanding the Three Credit Bureaus and Where to Place a Freeze

The three major credit bureaus—Equifax, Experian, and TransUnion—are companies that collect and store credit information about consumers. They maintain records of your loans, credit cards, payment history, and other financial behavior. Lenders use reports from these bureaus to make lending decisions. Because all three maintain separate credit reports on you, it's important to place a freeze with all three to ensure complete protection.

Equifax is the oldest and largest of the three bureaus, managing credit information on roughly 800 million individuals worldwide and 225 million in the United States. They maintain records of credit accounts, payment history, and public records like bankruptcies. Equifax experienced a major data breach in 2017 that exposed personal information of 147 million people, which increased awareness of credit freezes among consumers.

Experian is the second-largest bureau and maintains records on approximately 220 million individuals in the United States. They also provide credit monitoring, identity theft protection services, and credit reports. Experian operates slightly differently from the other two in some processes, so it's important to contact them separately when placing a freeze.

TransUnion is the third major bureau and holds credit information on approximately 210 million U.S. consumers. They also operate identity verification services and fraud prevention tools alongside their core credit reporting functions.

To place a credit freeze, you must contact each bureau independently. Here are the official ways to reach them:

• Equifax: Visit equifax.com/personal/credit-report-services, call 1-800-685-1111, or mail a request to Equifax Security Freeze, P.O. Box 105788, Atlanta, GA 30348-5788
• Experian: Visit experian.com/freeze, call 1-888-EXPERIAN (1-888-397-3742), or mail a request to Experian Security Freeze, P.O. Box 9554, Allen, TX 75013
• TransUnion: Visit transunion.com/credit-freeze, call 1-888-909-8872, or mail a request to TransUnion Security Freeze, P.O. Box 2000, Chester, PA 19016-2000

Most bureaus now allow you to place, temporarily lift, or permanently remove a freeze through their websites. The online process typically takes 10-15 minutes per bureau. When you place a freeze, the bureau will send you a confirmation letter with a unique PIN (personal identification number). Keep this PIN in a safe place—you'll need it if you want to temporarily lift the freeze later or remove it permanently.

Practical takeaway: Contact all three bureaus separately to place a freeze on your entire credit file. Save the confirmation letters and PINs they provide, as you'll need them for future freeze management.

Online Method (Fastest)

Visit the bureau's website (equifax.com, experian.com, or transunion.com) and navigate to their security freeze section. You'll be asked to provide personal information including your name, address, date of birth, Social Security number, and potentially other identifying details. The bureau uses this information to verify that you are the actual person on the credit report. Once verified, you can request the freeze immediately. The bureau will provide a confirmation number and typically send a confirmation letter by email or mail within 3-5 business days.

Phone Method

Call the toll-free number for each bureau. Have your Social Security number, date of birth, and current address ready. Explain that you want to place a security freeze. The representative will verify your identity and place the freeze over the phone. They'll provide you with a confirmation number and information about your PIN. A confirmation letter will be mailed to you.
