CoPIRG, the consumer advocacy group, urged Colorado consumers to immediately freeze their credit reports with the three major credit bureaus after fees to do that were lifted on Friday. And while they are at it, they should also freeze their accounts with a lesser known bureau that cellular providers use. “Go ahead and do one of the simplest things you can do to protect your identity,” urged Danny Katz, director of CoPIRG, at a news conference in Denver. Equifax, Experian, and TransUnion now allow consumers to freeze or unfreeze their accounts at no charge.
