"Honda 100371240 is confirmed in the FlyerTalk IHG rate codes thread, where a moderator immediately responded: "Unless you're employed by one of those companies, I would avoid using these codes at all. They do often ask for ID." Honda employees travel heavily to IHG properties near manufacturing hubs (Ohio, Indiana, Alabama) which are predominantly Holiday Inn / Crowne Plaza tier — mid-range enforcement. The 9-digit code format is consistent with large-account codes that IHG's system flags for verification."

"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"

"I had the same experience with the IBM corporate rate. When I went to IBM sites to install machines they always said stay at one of these hotels and tell them you need the IBM rate. Always worked and saved a lot of money and I always got full credit with the hotels frequent stay program."
