I think that the following opinion letter from the FTC hits this right on the head and supports the fact that the original suggested action in this thread would not be deemed a permissible purpose.
Here's an excerpt:
Section 604(a)(3)(A) of the FCRA gives a creditor a permissible purpose to obtain a consumer report without the consumer's consent "in connection with a credit transaction involving the consumer on whom the information is to be furnished and involving the extension of credit to, or review or collection of an account of the consumer." Section 604(a)(3)(F)(ii), which relates to deposit or other non-credit accounts, similarly provides a permissible purpose "to review an account to determine whether the consumer continues to meet the terms of the account." When obtaining consumer reports for such purposes, creditors need not comply with prescreening disclosure requirements because these transactions are exempt under Section 603(m)(1) of the FCRA.(2)
Your questions raise the issue of whether a creditor in a closed end credit transaction may exploit consumer reports obtained for "review" purposes in order to market its products or services. In the circumstances you described, we believe the answer is "no.". First, "review" is not a purpose for which a closed-end creditor would ordinarily need to obtain consumer reports on its customers. In commenting on the proposed provision which became Section 604(a)(3)(F)(ii), the Senate Committee on Banking, Housing, and Urban Affairs stated:
Like creditors, banks and others may need to consult a consumer's report in order to determine whether the consumer's current account terms should be modified. For example, the institution may provide more favorable pricing terms after consulting the report. The permissible purpose created by this provision, however, is limited to an account review for the purpose of deciding whether to retain or modify current account terms. (emphasis added).(3)
The terms of a closed-end credit transaction are predetermined and generally may not be changed unilaterally by the creditor unless the contract expressly provides for such action (e.g., in the event of default). Therefore, the creditor is unlikely to have a reason to consider "whether to retain or modify current account terms" and, thus, would not have any routine need to procure consumer reports to "review" its accounts. Second, the credit bureau must, pursuant to Section 607(a), require the creditor to "certify the purposes for which the information is sought, and certify that the information will be used for no other purpose." (emphasis added). Because Section 604(a) provides no authority for a creditor (or any party) to use a consumer report for marketing purposes,(4) a creditor would violate its certification by using an existing report in such a manner.
