Similar to the National Do Not Call Registry, there is a list for people who don't want pre-approved credit applications or insurance offers. Started in December of 2004 and run jointly by credit reporting companies Equifax, Experian, Innovis and TransUnion, the service is free and allows you to opt out either permanently or for five years. Visit: www.optoutprescreen.com or call (888) 5-OPTOUT or (888) 567-8688.
