A security freeze is an identity theft prevention measure in which a consumer restricts access to his credit file. Lenders and creditors (such as credit card companies) will not extend new credit to a consumer if they can't see the consumer's credit report. Thus, an identity thief will have a hard time opening a new account if the consumer's credit is frozen.
The Attorney General recommends consumers freeze their credit files. This will not prevent consumers from applying for a loan, credit or insurance in the near future. Instead, it prevents others from opening new accounts without your authorization.
