Transunion Credit Freeze

Placing a Security Freeze will prevent lenders and others from accessing your TransUnion Credit Report entirely, which will prevent them from extending credit. Because of stringent security features, you will need to place a Security Freeze separately with each of the three major credit reporting companies if you want the freeze on all of your credit files. A Security Freeze remains on your credit file until you remove it or choose to lift it temporarily when applying for credit or credit-dependent services.
