"Bristol-Myers Squibb's code 5298 is a four-digit numeric code, which circulates far less widely in public forums than three-letter ticker codes — numeric codes are harder to guess, share, and remember, reducing abuse volume. hotelcorporatecodes.com rates it "Sometimes." BMS is a major pharma company with significant NYC/Princeton NJ and Boston presence; properties in those markets may have greater account familiarity. The numeric format provides a slight practical risk reduction vs. a recognisable ticker code, but the company size and urban market concentration keep it at Medium."

"My last couple of corporate RFID cards had no company name on them for security purposes. My current company doesn’t do business cards. I use my Bonvoy card for corporate travel to get the points. I’d have to write them an email standing at the check in desk, I guess."

"I work front desk and it seems like management is really pushing to check IDs for any special rate. Personally im lazy and also don’t care that much to start a confrontation so I only verify govt rates and employee rates, but yes it is being enforced more harshly. Corporate rates I guess are easy to find online and thus abused. Again, I don’t care that much because they’re still pricey anyway !!"
