"HSBC's HSB code is listed across all major aggregators and rated "Sometimes" by hotelcorporatecodes.com. HSBC has a formal Marriott Bonvoy partnership (HSBC Premier cardholders receive complimentary Silver Elite status), making the brand relationship well-known to hotel staff — but this awareness cuts both ways. Finance-sector Medium calibration applies, with higher risk at NYC Midtown and London properties where HSBC has dense employee concentration."

"I have a close friend who is a GM at a Marriott property in a fairly large US city (top 25 metro population). Their opinion is basically, "Hey, it's business. I'm not turning away a paying guest if they don't have the right ID." In this person's younger days as a front desk agent, they enjoyed catching people trying to use a corporate rate that the guest was not entitled to. As they became higher up and saw the books, occupancy rates, etc... Corp ID's became far less important than filling rooms."

"I work as a consultant and frequently ask for and use my client's rates (at their insistence, since I will be billing them back). I have been asked for ID maybe one time in 15 since February, when it was announced in this forum that rates would be ID'ed."
