"Do hotels that accept this code ask for a company ID? i wanted to use this code at the Park Hyatt Tokyo, but I don't work for General Electric."

"I mean, you can book the rate, but 100% PH Tokyo requires proof of employment. I had to email from corp domain and provide a business card (Dec 2022). If you show up and can't provide proof of employment, either you'll be paying a very expensive full price for your stay, or they'll invalidate your reservation."

"We are pleased to note you have a future reservation on xxxxxx, 2010 made through hyatt.com. I do kindly ask that you bring your valid working ID in order for us to be able to confirm the corporate rate at time of check-in which will be cross referenced with the company. Unfortunately of late we have been experiencing misuse of some of our corporate rates, with your company a target and we have had to implement tighter controls in this regard."
