"Coca-Cola's IHG code (128813) is for one of the world's most recognized brands. IHG enforcement is tier-based: InterContinental Atlanta (near Coke HQ in Atlanta GA) regularly sees Coke employees and has established verification procedures. Holiday Inn Express: essentially never checks. Coca-Cola has dedicated travel partnerships with major hotel chains — the contract likely specifies usage verification protocols. hotelcorporatecodes.com notes Coke codes at "⚠️ Sometimes" at IHG."

"Yesteryear it wasnt so risky sinc ethe CX policy was Day of @ Check-in time, so as long as you got there before the CX time was past, then if carded all you had to say was OK CX the res then. That doesnt exist any longer as its now 24 hrs before if not earlier, so no ID they simply will charge the CC you used when you made the res , forget about Disputing it as the hotel will produce the res and their CX policy and that you used a code that you werent entitled to use"

"Overall, I have been asked for proof of corporate id or business card especially when using negotiated rates at individual properties. Now at most of these places our company has deeply discounted rates that can be 50% off the BRG and may have last room guarantee too. For example, I have been asked at the Hilton KL, IC Strings Tokyo, IC Jakarta, IC Frankfurt, IC GS Hong Kong, CP Zurich to name just a few. From friends experiences the GH Singapore is also known to ask for proof if some of the quite low negotiated rates are used. Now usually, I was asked once and then it was done and only twice at the Hilton KL, but not all the time on every stay."
