"JP Morgan Chase's Marriott code JPM is a high-profile financial institution code. FlyerTalk's "Corporate ID required???" thread specifically mentions financial sector codes in NYC/Chicago as more likely to be audited: "The SF Marriott was specifically noted for cracking down on corporate code abuse." Chase has massive employee headcount (250,000+) making verification less targeted, but JPMorgan's Marriott discount at full-service NYC/Chicago properties can be substantial. hotelcorporatecodes.com: "⚠️ Sometimes."

"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."

"We know what the various Deloitte, EY, PwC, Google, Meta, etc badges look like. If you work for the company, it’s not a problem to verify that you work there. We do this for the random people that say they work for Deloitte, when in reality, they just refill the vending machine at a Deloitte office."
