"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."

"This Deloitte code circulates widely among current and former staff. IHG auditing materials note that large firms like Deloitte and IBM have codes hard-coded into IHG's auditing software to trigger a request for ID. The "Stop at Desk" flag has been observed: certain high-value codes block issuance of a Digital Key until physical ID is presented at the front desk."

"Enforcement is highly fragmented across brand tiers. At Holiday Inn / Holiday Inn Express: minimal enforcement. At InterContinental and Kimpton: almost always verify. One user stated: "Airport Holiday Inns rarely check credentials, while InterContinentals in major cities almost always do." Properties near Seattle headquarters offer deeper discounts but face stricter verification."
