You may want to include in your account agreement or similar brochure that you may/will pull a credit report.
However, pulling credit reports and then using them for cross-selling products and services is not a permissible purpose. A credit report may only be used for the purpose for which is was obtained, in your case for qualification for the account. If you want to use credit bureau info for cross-selling/marketing purposes, you would need to establish pre-screening procedures and disclosures and be prepared to make a firm offer of any products for which the pre-screened person qualifies.
