Answer:
By "prospective customers" I assume you mean potential customers meeting your qualifications. This then, depends on what you require. If this includes a credit report of any kind, you will need authorization, a business reason. A secret prequalification on your part wouldn't be sufficient. I recommend you avoid that.There is no preferred method of which I am aware. It just depends on what works for your bank staff, and doesn't violate any laws or regulations.
