"I occasionally try to get the corporate rate for a company I'm visiting in the area (for sales/consulting). Only once has a front desk clerk asked me to prove my eligibility, and she was satisfied by me giving the name and telephone number of the person I was visiting."

"My employer does not have a corporate rate but when I'm consulting for a company that does, I use theirs. I've only been challenged for identification once. In that one situation I explained the consulting arrangement, and the desk clerk accepted it without a badge or business card (neither of which I had anyway)."
