"Ace Hardware's IHG code (100862437) is a retail cooperative corporate code. No FlyerTalk or Reddit discussion found specifically about Ace Hardware IHG verification. Retail sector codes at IHG Holiday Inn Express properties are essentially never verified. Ace Hardware is a dealer cooperative, not a traditional employer — verification of "Ace employee" status is inherently ambiguous. IHG enforcement is tier-based: InterContinental properties might ask; Holiday Inn Express properties rarely do."

"I work for BofA and the internal discounts website didn't list codes, instead directing employees to contact individual properties. I later confirmed the code is 109568. Unless you're employed by one of those companies, I would avoid using these codes. They do often ask for ID at InterContinental properties, though Holiday Inn locations rarely enforce."

"Arizona State University's IHG code (ASU) is an academic institutional code. University codes at IHG properties are used primarily for conference and academic travel. No FlyerTalk thread discusses ASU IHG verification incidents. Academic/education sector codes at IHG are the lowest-enforcement category — holiday Inn / Crowne Plaza near Phoenix (where ASU's main campus is located) are familiar with ASU travelers and rarely request ID."
