"GE International Hyatt code (13307) follows Hyatt's standard verification pattern for major industrial codes. FlyerTalk documents Hyatt as "notorious for checking ID, especially at Park Hyatt." GE International implies non-US travel, concentrated in Asia/Europe where Hyatt verification is highest. Park Hyatt and Grand Hyatt in global business centers regularly encounter GE employees and know what GE badges look like. Hyatt Place and House: essentially never check."

"I believe it's depends on the hotel. Hyatt will not verify your job status, as long as you made the bookings. However hotel has right to check your badges if they wish. it is very unlikely to harm you, the worse they can do is request you to make full public rate payment. I stayed at Conrad Shenzhen last year with my friend. He kept using his old company's rate code to make Hilton hotel booking even though he has already left. The front desk asked him to verify but he couldn't, so we made full payment in the end, no drama."

"We may have an issue of semantics regarding the travelzoo code. Often when Travelzoo has a special rate for a Hyatt Hotel that rate is also shown in the "Special Offers" section for the particular hotel on the Hyatt Website. The code for the comparable "Special Offer" is 13147 which is often referred to as the Travelzoo code. As this code is available on the website, it gets both stay credit and points. At least, this is my impression."
