How to enter an IHG corporate code

1. Go to ihg.com and open the booking form for your destination and dates.
2. Look for the Corporate ID / Corporate or Group Code field on the search form. This is the field IHG's own booking widgets use for contracted rates.
3. Type the company's code in that field, then run the search.
4. If a property doesn't honor the code, it simply won't return a corporate rate — try nearby IHG properties or different dates.
5. Compare the corporate rate against the member and public rates before booking, and keep proof of eligibility ready for check-in.

Why IHG code numbers come in two lengths

Of the 30 codes in the verified table above, 17 are six digits and 11 are nine digits. One is eight digits (University of Texas, 99502056) and one is letters (Arizona State University, ASU). Both length families are real: 3M is 101672, Microsoft is 100857558, and each appears in three or four independent listings.

A longer code is not a better code. Length here tracks which account system issued the number, not how large the discount is and not which brand tier it prices on. What length is actually useful for is telling a corporate ID apart from the other numbers that circulate beside it.

Google's own people-also-ask box for this search contains "What is the IHG promo code 70027?". We looked it up. 70027 is five digits, and it is not a corporate ID at all: it was an IHG One Rewards registration code for instant Diamond elite status, roughly three years old, and the pages still carrying it label it expired. Typed into the Corporate ID field it does nothing.

• Six or nine digits — the shape every corroborated IHG corporate ID on this page has.
• Five digits — treat with caution in this context. Numbers this short around IHG are usually promotions, elite-status offers or member rates, not a contracted rate.
• One company, two numbers — FedEx, IBM and Lowe's each have a corroborated six-digit code and a second, uncorroborated number circulating beside it. We keep the second one in the table below, not above.

One source we dropped for this brand. We no longer count hotel-corporate-code.com as a source for IHG. Its IHG table gives the same number to unrelated companies — 109193 under EY, Exterran and Facebook; 106372 under HP and Honeywell; Coca-Cola's 128813 under "drury"; GE's 102806 under "Gillette" — and it lists a single digit, 7, as a Deloitte code. That is a whole-source rejection, not a row deletion. Dropping it left the verified table at 30 codes and cut the table below from 36 rows to 15.

Codes to check before relying on them

These are either confirmed by only one listing, or the listings disagree with each other, or one listing flags them as unverified or likely expired. Test before relying on any of them.

Restrictions (as the listings state them)

• Corporate rates are tied to a company's negotiated agreement. You can use a code only if you have a legitimate business affiliation with that company — as an employee, a client, or a supplier the company has cleared.
• Expect to prove it at check-in: a company ID, a work email address the hotel can verify, or other quick proof. Hotels increasingly verify eligibility, and enforcement is uneven by region.
• A code being listed is not permission to use it. If the hotel determines you don't qualify, it can reprice your booking to the best public or loyalty rate.
• Most corporate rates are intended for business travel. Leisure trips are a gray area, and some leisure destinations won't honor the code at all.
• Availability varies by property and date. Not every IHG brand or property participates in every agreement.

How we checked the IHG codes

30 codes reached the verified table; 36 sit in the check-first table. Both tables come out of the same pass over public listings, and the split is decided by one rule: at least two independent listings have to agree.

Two things about IHG make that check worth the trouble. First, the numbers are long — eleven of the thirty confirmed codes are nine digits — and a transposed digit inside a nine-digit number is hard to spot by eye, so a wrong code and a right code look equally plausible on the page. Second, as the next section shows, the same digits really do turn up filed under different companies. That is a copying artefact rather than a property of the codes, but it means a collision here is not automatically an error and has to be read one case at a time.

Both tables come out of the same pass over public listings. The rule, and the reasoning behind it, are set out on how we verify a code.

Where the IHG listings disagree

Two patterns, both visible in the check-first table.

One number, several owners:

• 109193 — filed under EY, under Exterran and under Facebook, by three separate listings.
• 106372 — filed under HP and under Honeywell.
• 100211707 — filed under Lenovo and under Lowe's.
• 422835 — filed under IBM and under Deloitte. IBM's confirmed IHG code is 243132, carried by three listings.
• 102806, 103772, 128813, 104256 — each of these is a check-first entry that collides with a confirmed code elsewhere on this page: General Electric's, Ford's, Coca-Cola's and Siemens' respectively. The check-first entry is filed under a different company in each case.

One company, several numbers:

• Deloitte — three numbers circulate (100119498, 422835, 7). One listing marks 100119498 as likely expired, which is why it did not reach the verified table even though two listings carry it. Two listings agreeing is necessary here, not sufficient.
• FedEx — 109207 is confirmed by three listings. A separate listing gives FedEx 100190819, and in that same list seven FedEx units (Custom Critical, Freight, Ground, Trade Networks and others) each carry a number of their own.

Neither pattern makes a code wrong. It means that for IHG — as for Hyatt and Choice — a number you find on another site is worth one extra test before you build a trip around it.
