"JC Penney's Hilton code N0381437 is a retail corporate code. Hilton's general corporate verification rate of ~20% applies primarily to full-service urban properties. JC Penney's suburban mall-anchor presence means most JCP-related hotel stays are at select-service properties (Hampton, Hilton Garden Inn) where enforcement is minimal. JC Penney's workforce reduction following bankruptcy further reduces the volume of legitimate JCP code users."

"hotelcorporatecodes.com lists BASF N0001125 in the "Rarely" ID check category alongside Dow Chemical, McDonald's, Nestlé, and Siemens. Chemical/industrial sector codes historically draw less scrutiny than consulting or finance codes. FlyerTalk noted: "The internet and all the sharing of corp rate codes has caused some hotel properties to have a lower ADR" but enforcement remains uneven; industrial company codes at US Hilton properties are rarely challenged."

"Bosch code 315000125 is an industrial-sector code. A live booking test found the Bosch Hilton rate "not available" during testing periods. Codes that rarely resolve to a live rate are also rarely verified — you cannot be caught for a rate that doesn't apply. When it does resolve, Bosch is an industrial-sector code similar to BASF and Siemens, which cluster in the low-enforcement tier at Hilton."
