KTL, I believe what happens with most pre-qualifying creditors is that the creditor "buys" (from a bureau) a list of consumers that "fit" a pre-determined credit profile, and then the creditor solicits those consumers. They'll generally do a hard pull after you finish the full application, and if they info you supply matches the "pre-screened" info from the bureau, then you're likely to be formally approved. In other words, a creditor will buy a list of consumers' names where, for example, credit scores are between 500-600 with recently established credit... and they'll market their product to that crowd. It's the same for creditors looking for "spotless" credit histories to market high-line card to. They will stop marketing to you, however, if you go through the "opt-out" procedures. Good luck to you.
