"AON's Radisson code (55321) is for the consulting and insurance brokerage firm. Radisson's general franchise-based enforcement policy: "Most Radisson corporate codes do not require ID verification." AON has a documented Hyatt code with Medium risk — but Radisson's franchise network applies far less consistent enforcement. No AON+Radisson specific incident documented. The Americas Radisson properties (now Choice Hotels) have even lower enforcement than the European-managed properties."

"ExxonMobil's Radisson code (50614) carries far lower risk than the widely-discussed Marriott XOM code. A Fishbowl post titled "Anyone ever use another company's corporate discount code for Marriott? XOM Exxon code is showing a significant discount" confirms ExxonMobil code discussion is primarily Marriott-focused. Radisson operates with far lower enforcement than Marriott. The Americas properties (now Choice Hotels) have minimal verification infrastructure. No ExxonMobil+Radisson incident documented."

"No specific FlyerTalk or Reddit threads found discussing EY/WP1057 ID verification at Radisson. General Radisson enforcement pattern: enforcement is "highly variable by individual property" given the franchise structure — only 3 of ~642 properties are company-owned. The Americas division was sold to Choice Hotels in 2022, further fragmenting policy. Community consensus across travel blogs lists Radisson as "low enforcement overall." No reports of systematic ID checking for EY-class corporate codes at Radisson properties in any indexed community discussion."
