How to Freeze Your Credit with TransUnion: A Complete Step-by-Step Guide

Introduction to Credit Freezes and TransUnion

A credit freeze with TransUnion restricts access to your credit report, making it harder for identity thieves to open new accounts in your name. This guide explains how to place, manage, and lift a freeze, what a freeze does and does not block, and how it compares with other risk-management options. Steps are based on TransUnion’s documented process and may vary slightly depending on your location and account status. Freezing and unfreezing your credit does not change your credit score.

What a Credit Freeze Does (and Does Not Do)

A freeze controls who can access your credit report at the major nationwide bureaus, including TransUnion. When your file is frozen, new creditors and most lenders cannot view your report, which typically prevents new accounts from being opened without your permission. A freeze does not affect your credit score, existing accounts, or your ability to view your own report. It also does not stop fraud like identity theft after an account is already open, prevent criminal background checks, or block access to your credit report for permitted uses, such as prescreened offers you opt into or account reviews by current creditors.

What Freezing Blocks

• New account applications that require a credit check with TransUnion.
• Most hard inquiries initiated by lenders you do not already have a relationship with.

What Freezing Does Not Block

• Existing account fraud or account takeover attempts.
• Employment, insurance, or rental background checks where permitted by law.
• Credit checks for preapproval offers you have not declined.

Key Facts: Freezing Your Credit at TransUnion

When to Consider Freezing Your Credit

If you are concerned about identity theft, have experienced fraud, or want to reduce the risk of unauthorized new accounts, a credit freeze is a preventative control. It is most effective when all three major bureaus are frozen, but you can start with TransUnion and add the others later. A freeze is one layer of defense; complement it with credit monitoring for accounts you already hold and safe handling of personal information. Decide based on your comfort level and whether you plan to seek new credit, which requires temporarily lifting the freeze.

How to Place a Freeze on Your TransUnion Credit File

You can freeze your TransUnion credit report online, by phone, or by mail. Each method requires identity verification, such as your Social Security Number, date of birth, and answers to security questions. An email confirmation and a record number are provided once the freeze is placed. If you prefer offline options, you can complete the freeze by mail with a notarized identity affidavit and copies of supporting documents. Fees do not apply under federal law in the United States.

Online Placement

1. Go to the official TransUnion consumer portal and locate the credit freeze section.
2. Provide your name, address, date of birth, and Social Security Number.
3. Answer security questions to verify your identity.
4. Select the freeze option and review the confirmation screen; save the confirmation and case number.
5. You will be prompted to create a PIN or memorize a password needed to lift the freeze later.

Phone Placement

1. Call TransUnion’s authorized freeze line during business hours listed on the official site.
2. Provide the same identifying information you would include online.
3. Follow the agent’s instructions; you will receive a confirmation and case number by mail or email if requested.
4. Record the PIN or password and keep it in a secure place.

Mail Placement

1. Download and print the credit freeze request form from the official TransUnion website.
2. Complete the form with your personal information and include copies of acceptable identification, such as a driver’s license and Social Security card.
3. Include a notarized identity affidavit if requested.
4. Mail the completed package to the address specified on the form; do not send original documents.
5. Allow 1–3 business days for processing, and keep a copy of everything you send.

How to Manage and Monitor Your Frozen Credit

After placing a freeze, store your PIN, password, and confirmation details securely so you can lift the freeze quickly when needed. Keep a list of when you froze each bureau and any confirmation numbers; this is especially helpful if you move or change contact methods. Periodically review your TransUnion report for accuracy and ensure that no unauthorized activity has occurred on existing accounts. If you apply for new credit, remember to lift the freeze temporarily, and confirm that it has been re-applied afterward.

Temporary Lifts and Selective Sharing

• Temporary lift: Specify a date range (e.g., 30 days) when a lender can access your report; lift can often be done online or by phone.
• Current creditors: You do not need to lift a freeze for existing account holders to review your file, as they can access it without the freeze.
• Preapproved offers: A freeze does not stop prescreened offers; opt out separately if you do not want these lists.

Comparing Freeze with Other Risk-Management Options

Freezing your credit is different from a fraud alert or credit monitoring. A fraud alert prompts lenders to verify your identity before issuing new credit and lasts up to one year (renewable); it is easier to place than a freeze but offers weaker protection. Extended fraud alerts and active duty alerts are available for identity theft victims and military personnel, respectively. Credit monitoring watches your existing accounts and public records for changes and can be useful for ongoing awareness, but it does not prevent new accounts from being opened. A freeze is the strongest available prevention for new account fraud; choose the combination of tools that best fits your risk tolerance and plans to apply for credit.
