What These Codes Actually Cover
This is the part that surprises people. IHG corporate codes are not limited to Holiday Inn and Crowne Plaza. They work across the entire IHG portfolio, which in 2026 includes InterContinental, Regent, Kimpton, Hotel Indigo, Voco, Staybridge Suites, and Candlewood Suites. The discount percentage varies by brand and location, but the code itself is universally accepted through the booking engine.
A single IHG corporate code can cut rates across ten distinct hotel brands, from the budget reliability of Candlewood Suites to the polished luxury of Regent. The system rewards those who bother to type in six to nine digits.
The Big Four consulting firms tend to secure some of the deepest discounts. Deloitte, PwC, and EY employees stay at IHG properties in extraordinary volume, and their codes reflect that buying power. Tech companies like Google, Microsoft, and Amazon are right behind them.

How to Book with an IHG Corporate Code
The process is straightforward but easy to miss if you have never done it before. Here is exactly how it works.
Step 1: Go to IHG.com or open the IHG One Rewards mobile app. Start a search by entering your destination, dates, and number of guests.
Step 2: Before hitting search, look for the "Special Rates" or "Add a Code" dropdown. On the website, this appears directly below the date fields. On the app, you may need to tap "More Options" to reveal it.
Step 3: Select "Corporate ID" from the rate type options. A text field will appear. Enter the code exactly as listed, no spaces, no dashes.
Step 4: Run the search. Corporate rates will appear alongside standard rates, member rates, and any promotional pricing. Compare carefully. In some cases, a flash sale or IHG Accelerate promotion may actually beat the corporate rate on a given night.
Step 5: Select the corporate rate and complete your booking. You will earn IHG One Rewards points on the stay, and the rate is typically cancellable under the same terms as a standard flexible booking.
A Few Things to Watch Out For
Corporate codes are powerful, but they are not foolproof. There are situations where they will not produce the result you expect.
Availability also matters. Corporate rates are allocated in blocks, and during peak travel seasons or major events, those blocks can sell out even when standard rooms remain available. Booking early gives you the best shot. Weekend stays are another gray area. Many corporate agreements are structured around business travel patterns, so Monday through Thursday rates are almost always stronger than Friday through Sunday.

Common Questions
Can I use an IHG corporate code if I do not work for that company?
Technically, anyone can enter a code during booking. However, IHG's terms of use state that corporate rates are intended for employees, contractors, and authorized travelers of the affiliated company. Enforcement varies widely by property. Some hotels never check. Others will ask for a company ID or business card at check-in.
Do IHG corporate codes work internationally?
Yes. These codes are valid at IHG properties worldwide. The discount percentage may differ between regions, but the code itself is recognized globally by IHG's reservation system.
Will I still earn IHG One Rewards points on a corporate rate?
Absolutely. Corporate rate bookings made through IHG.com or the IHG app are fully eligible for IHG One Rewards point accrual and elite night credits. Third-party bookings using these codes are not.
How often do these codes change?
Most large corporate agreements are renegotiated annually, but the actual code numbers tend to remain stable for years. The rates attached to those codes may shift with each contract cycle.
Can I combine a corporate code with a promotional offer?
You cannot stack two rate codes on the same booking. However, you can combine a corporate rate with IHG One Rewards promotions like Accelerate, PointBreaks, or seasonal bonus point campaigns. That combination is where the real value accumulates over time.
Are corporate rates always the cheapest option?
Not always. IHG occasionally runs member-exclusive sales or advance purchase rates that undercut corporate pricing. Always compare at least three rate types before finalizing your reservation. The five minutes of comparison shopping can save you more than any single code.
