"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."

"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."

"IHG corporate codes vary by brand. Airport Holiday Inns rarely check credentials, while InterContinentals in major cities almost always do. The likelihood of a request for ID is based on the size of the discount — the greater the discount, the more diligent the front desk. Be prepared to be asked for company ID if the discount rate is more than the standard 15% given to most corporates, or if the company rate is a fixed rate lower than the hotel's ADR. Cisco's IHG code (954410926) sits alongside IBM and Dell in the widely-circulated FlyerTalk master list; tech-company codes at this tier typically yield 10-25% savings and trigger occasional verification at full-service properties but rarely at Holiday Inn Express tier."
