How to Request a TransUnion Credit Freeze

The best way to keep fraudsters from using your credit data is to get a credit freeze.

This safeguards your records and keeps identity thieves from being able to use your credit identity to open new accounts. You can also freeze your child's credit reports for free.

Unless you know you will soon need to access your credit, a credit freeze, also known as a security freeze, is worth considering. But if you anticipate needing to grant access to your credit data frequently or soon — for instance, you're applying for a new account, job or apartment — a fraud alert may be a better option.

Credit freezes have to be set up individually with each credit bureau: Equifax, Experian and TransUnion. Lifting freezes also has to be done individually. Credit freezes and thaws are free.

All three bureaus allow you to do this online, by mail or by phone. Here’s a step-by-step guide for freezing credit with TransUnion.

TransUnion credit freeze online

You will have to establish a TransUnion Service Center account in order to freeze your TransUnion credit online. You can also download and use an app if you prefer. You do not have to have a TransUnion account to place a security freeze by mail or by phone.

To open an account, or to freeze, you will be required to provide your name, the last four digits of your Social Security number, your address and birthdate.

Note that above the "I accept & continue" button is consent to send offers from TransUnion and partners. The default is yes. You will need to change it if you do not wish to receive them.

You will then be asked some identification questions, such as street numbers for past addresses, when credit accounts were established or approximate payment amounts on loans.

Important: While there are many monitoring products that can be purchased on the site, be careful to sign up only for the free credit freeze, if that is what you want. You should see references to a free freeze when you sign up.

With the freeze in place, you can still access your own file to check credit activity. You can check your free credit report summary from TransUnion on NerdWallet as often as you wish.

TransUnion credit freeze by postal mail

To freeze your credit by mail, send your request to TransUnion LLC, P.O. Box 160, Woodlyn, PA 19094. You will need to include your legal name, address, birthdate and Social Security number, along with copies of documents verifying your identification and address, such as a driver’s license, passport or utility bill.

TransUnion notes that mail is the slowest way to freeze credit.

TransUnion credit freeze by phone

Consumers may also initiate a freeze by calling 800-916-8800. You can complete the process using an automated system or opt to speak with an agent. Basic information — full name, any suffixes such a Jr., address, birthdate and Social Security number — will be required, and you may have to answer authentication questions as well.

Lifting a TransUnion credit freeze

Credit freezes must be lifted individually with each bureau. If you’re making a single credit application — say, getting preapproved for a car loan or an apartment — you may be able to find out which credit bureau’s data is used and unfreeze just that one, saving some time.

If unfreezing your credit online, you'll log in to your TransUnion Service Center account as you did to place the freeze. If you're unfreezing by phone or mail, you'll need to provide your name, address, birth date and Social Security number.
