"I work for BofA and the internal discounts website didn't list codes, instead directing employees to contact individual properties. I later confirmed the code is 109568. Unless you're employed by one of those companies, I would avoid using these codes. They do often ask for ID at InterContinental properties, though Holiday Inn locations rarely enforce."

"I stay primarily at IHG hotels and they never ask for proof that I'm associated with the corporate code I use."

"University of Texas' IHG code (99502056) is an academic institutional code. IHG enforcement: Holiday Inn / Crowne Plaza near UT Austin essentially never verifies academic rates. InterContinental Austin (if applicable) might theoretically ask, but university codes are the lowest-enforcement category across all IHG properties. No UT+IHG verification incident documented in public forums."
