I’m not sure if this is really true or not, but it appears to be. Check out this article about credit triggers. It’s on a political site but I also found information on NPR about it. (You can find those links in the first article).
Basically Experian can sell your information to creditors that allow them to keep track of your credit activities in real time. For people in debt, this means that as soon as you have new activity on your credit, the collectors may come calling rapidly.
For those of us that have good credit, it means that other lendors may see our inquiry in to a new mortgage or other credit and start bombarding us with offers via the phone etc to try to get our business. I haven’t experienced this but I think I’m going to do a bit more research on it. If it’s true, I think it’s wrong for Experian to do this. I want some control over who gets to look at my credit!
