Learn About Freezing Your Credit With TransUnion

Understanding Credit Freezes and How They Work

A credit freeze is a security tool that restricts access to your credit report. When you place a freeze with TransUnion (one of the three major credit reporting bureaus), the bureau will not release your credit information to potential creditors, lenders, or other businesses without your permission. This restriction makes it significantly harder for identity thieves to open new accounts in your name, since most lenders check your credit report before approving new credit.

TransUnion maintains credit files on approximately 215 million U.S. consumers. The bureau collects information about your payment history, outstanding debts, length of credit history, and other financial behaviors. This information gets sold to lenders, credit card companies, employers, and landlords who use it to make decisions about extending credit or hiring. When someone commits identity theft, they often try to open new credit accounts using stolen personal information. A freeze prevents those fraudsters from accessing the credit report they need to complete the application process.

It's important to understand that a freeze does not affect your existing accounts. Your current credit cards, loans, and other credit relationships continue to work normally. You can still use your existing credit, make payments, and access your accounts. The freeze only prevents new inquiries into your credit file.

The freeze remains in place until you remove it. You can temporarily lift a freeze (called a thaw) for specific time periods or for particular lenders. You can also permanently remove the freeze whenever you choose. Unlike credit monitoring services that watch for suspicious activity, a freeze is a preventive tool that stops unauthorized access before it happens.

Takeaway: A credit freeze with TransUnion stops the bureau from sharing your credit report with anyone who requests it, which is the primary tool identity thieves need to open fraudulent accounts in your name.

The Three Major Credit Bureaus and Why You Might Need to Freeze With All Three

The United States has three major credit reporting bureaus: TransUnion, Equifax, and Experian. These three companies maintain separate credit files on you and collect information from different sources. Many creditors report to all three bureaus, but not all do. Some lenders report to only one or two bureaus. Because of these variations, your credit information may differ slightly at each bureau.

When you place a freeze with only one bureau, the other two continue to share your credit information. This creates a vulnerability. An identity thief who cannot access your TransUnion report might successfully open an account by accessing your Equifax or Experian report instead. For maximum protection against identity theft, security experts generally recommend placing a freeze with all three bureaus, not just one.

TransUnion is one of the largest credit reporting agencies, maintaining records on roughly one-third of American consumers in their database. However, the other two bureaus maintain similarly sized databases. Your credit report at TransUnion may show different information than your reports at the other two bureaus because of timing differences in how information gets reported and how long it stays on your file.

Placing a freeze with all three bureaus requires separate requests to each company, though the process is similar at each. Most people can place a freeze online, by phone, or by mail. Each bureau has its own system for managing your freeze, so you'll receive separate confirmation numbers and may need to manage them somewhat independently. Some people keep these confirmation numbers in a secure location for future reference when they need to lift the freeze temporarily.

Takeaway: Place a freeze with all three major credit bureaus (TransUnion, Equifax, and Experian) rather than just one, since identity thieves can use any of the three bureaus to attempt opening fraudulent accounts.

How to Place a Credit Freeze With TransUnion

TransUnion provides several methods for placing a credit freeze. The fastest method is typically through the TransUnion website. You'll navigate to their credit freeze section and follow the online steps to initiate the freeze. The online process generally takes 15 to 20 minutes and provides immediate confirmation. You'll receive a confirmation number and a personal identification number (PIN) that allows you to manage your freeze in the future.

You can also place a freeze by calling TransUnion's customer service line. Their phone number for credit freezes is available on their website. When you call, you'll speak with a representative who will verify your identity by asking security questions based on information in your credit file. The representative will guide you through the freeze process over the phone. This method works well if you prefer speaking with a person or if you have questions about the process.

A third option is placing a freeze by mail. You'll need to send a written request to TransUnion's address (available on their website) along with copies of documents that verify your identity. This method takes longer—typically 3 to 5 business days after TransUnion receives your letter—but it creates a paper record of your request.

Regardless of which method you choose, TransUnion will ask you to verify your identity using personal information they have on file. This typically includes questions about your address history, previous accounts, or other details only you would know. This verification process protects your account from someone else placing a freeze using your personal information without your consent. After the freeze is confirmed, TransUnion will provide you with a PIN. Keep this PIN in a safe place, as you'll need it to lift or remove the freeze later.

Takeaway: You can freeze your TransUnion credit report online (fastest), by phone, or by mail. Each method requires identity verification to protect your account.

Managing Your Freeze: Lifting It Temporarily and Permanently Removing It

After placing a freeze with TransUnion, you maintain control over your credit file. If you need to apply for new credit—such as a mortgage, car loan, credit card, or rental application—you'll need to temporarily lift the freeze so the lender can access your credit report. TransUnion calls this a "thaw," and you can structure it in different ways depending on your needs.

You can request a temporary thaw for a specific period of time, such as 30 days or 60 days. This works well if you're actively shopping for a loan or credit card and expect multiple lenders to request your credit report during that window. Once the thaw period ends, your freeze automatically goes back into effect. You can also request a thaw for a specific company. For example, if you're applying for a mortgage with one particular bank, you can authorize that bank to access your credit report while keeping your freeze in place for everyone else.

To lift your freeze temporarily or permanently, you'll typically use the PIN that TransUnion provided when you placed the freeze. If you don't have your PIN, you can request one by calling TransUnion or using their website. Most temporary freezes can be lifted within minutes online or over the phone. The process is generally faster than placing the initial freeze.

If you want to permanently remove your freeze entirely, you can do so at any time through the same methods—online, by phone, or by mail. Once you remove a freeze, TransUnion will resume sharing your credit information with authorized inquiries. Some people remove their freeze after a significant life change (such as after closing on a home purchase) but then place a new freeze later. Others keep their freeze in place permanently and simply lift it temporarily whenever they need to apply for new credit.

Takeaway: Use your PIN to temporarily lift your freeze when applying for new credit, or permanently remove it whenever you want. Temporary thaws can be set for specific time periods or specific companies.

Understanding Costs, Timelines, and Legal Protections

Federal law requires TransUnion to place and remove a credit freeze at no cost. You will not be charged a fee to place a freeze, lift it temporarily, or permanently remove it. This has been the case since 2018 when federal law changed to make free credit freezes available to all consumers nationwide. Before this change, some states required free freezes while others did not, but current federal law guarantees this protection for everyone.

However, other services that TransUnion and other bureaus offer—such as credit monitoring, credit scores, identity theft insurance, or credit reports with analysis—may cost money. A credit freeze itself is always free, but you should be aware of what services you're purchasing if you choose to buy additional products.

The timeline for placing a freeze varies by method. If you place a freeze online, it typically becomes effective within 24 hours. If you place it by phone, it generally goes into
