Marriott is the largest hotel company in the world, and its loyalty program is among the most popular with business travelers. If you travel for work, as I do, you’ll probably stay at a Marriott at some point and want to know how to book with a Marriott corporate code.
What makes Marriott’s corporate program different from other chains is the sheer number of legacy codes still floating around the travel community and the Breakaway leisure program that lets employees use company rates for vacation travel. The challenge isn’t finding codes — it’s knowing which ones still work, which ones are defunct, and how to compare them efficiently.
How Marriott Corporate Codes Work
Marriott corporate codes are short 3-character identifiers (occasionally with a number, like SW8 or A70) that link to negotiated rates between Marriott and specific companies or organizations. When you enter a code during booking, Marriott’s system applies the corresponding discount if that property participates in the program.
Here’s what I’ve learned about how these codes actually work in practice: Large consulting firms like Deloitte (DTC), Accenture (ACC), and IBM typically have chain-wide agreements that work at most Marriott properties globally. Fortune 500 companies often have both chain-wide rates and deeper property-specific discounts near their headquarters or major offices. Universities usually offer good rates within 30-50 miles of campus but limited coverage elsewhere.
The discount you get varies significantly by property, market, and date. I’ve tested the same corporate code across multiple regions and seen wildly different results — a code that delivers 18% off in North America may deliver 29% off in Asia, or vice versa. Your mileage will vary.
Benefits of Marriott Corporate Codes
Most Marriott corporate rates include flexible cancellation up until noon on your arrival day, which is more generous than the standard 24-hour policy. Corporate negotiated rates are classified as Qualifying Rates under the Marriott Bonvoy terms, which means you earn base points, stay credit, elite night credit, and receive all your elite benefits — room upgrades, late checkout, lounge access, and any other perks you’d normally receive on a standard rate.
Some corporate agreements include additional perks like complimentary breakfast or parking, though these vary by company and property. The rate details screen will show exactly what’s included before you book.
Who Actually Qualifies
Corporate rates are intended for employees, contractors, and consultants traveling on behalf of the company that negotiated the rate. Some companies extend eligibility to retirees or allow personal travel use — you’d need to check your company’s specific policy.
Marriott’s official language on eligibility verification, taken directly from their booking flow, asks guests to “be prepared to show proof of eligibility for your rate (such as a membership card, corporate or government identification card, or proof of your age).”
In practice, enforcement varies dramatically. In my experience, Marriott properties may ask for proof of eligibility at check-in, particularly at full-service hotels in major cities or during high-demand periods. Airport hotels and convention center properties tend to verify more frequently than suburban properties.
What You May Need to Show at Check-In
Marriott properties can verify your eligibility at any time. While enforcement varies, you should be prepared to provide:
- Company ID badge or employee credential
- Business card with company affiliation
- Corporate credit card bearing the company name
- Work email address matching the company domain
- Travel authorization or approval documentation
- Proof of contractor relationship (for consultants/vendors)
If you can’t demonstrate eligibility, the hotel may reprice your reservation to the best available public rate, remove corporate benefits, or in busy periods, potentially cancel the reservation.
The Best Corporate Codes by Company Size & Type
Not all corporate codes are created equal. The best discounts typically come from companies that bring Marriott significant volume, which means large consulting firms and Fortune 500 corporations with frequent business travel.
Global Consulting Firms (Best Chain-Wide Coverage)
The consulting firm codes work consistently across Marriott’s global portfolio because they negotiate system-wide agreements based on massive annual spending.
Because their employees travel to client sites worldwide, these codes are generally “Chain-Wide,” meaning they work at almost any Marriott property, from a Moxy in Berlin to a Ritz-Carlton in Tokyo.
- Deloitte (Code: DTC) — In my testing across multiple regions, DTC consistently delivered the strongest chain-wide savings — roughly 18-20% off in North America and Europe, with deeper discounts in Asia. The gold-standard code.
- Accenture (Code: ACC) — Best for global coverage. Typically 15% off in North America and Europe. A FlyerTalk contributor reported using ACC for years without being asked for ID, though your experience may vary.
- IBM (Code: IBM) — Ideal for consistent worldwide availability. Roughly 15% off in North America and Europe, with meaningfully deeper discounts in Asia.
- PwC (Code: PCW) — Strongest in major financial hubs; 15-20% off in testing.
- A.T. Kearney (Code: ATK) — Roughly 15% off in North America and Europe; stronger in Asia.
Fortune 500 Companies (Best Near Headquarters)
Unlike consulting firms, these corporations negotiate “City-Specific” deeper discounts. If you are traveling to a city where one of these giants is headquartered, these codes can outperform any other discount on the market.
- Procter & Gamble (Code: PAG) — Headed to Cincinnati? Use this code. Also delivers meaningful savings in Asia.
- Ford Motor Company (Code: FRD) — Dominates the Detroit and Dearborn markets.
- 3M Company (Code: MMM) — The go-to code for Minneapolis/St. Paul.
- General Electric (Code: GEE) — 15% chain-wide with stronger savings in Asia. Note: some travelers have reported GEE may no longer work as of mid-2025, so test before relying on it.
- Microsoft (Code: MCO) — Best for Redmond and Greater Seattle; deeper discounts in Asia.
- General Motors (Code: GMC) — 15% chain-wide; best near Detroit.
Technology Companies (Strong in Tech Hubs)
Tech company codes work best in San Francisco, Seattle, Austin, and other technology centers where these companies have significant presence.
- Apple (Code: APL) — 10% chain-wide with substantially deeper discounts in Asia.
- Apple Computers (Code: APC) — Separate code from APL. 15-30% off in testing.
- Google (Code: GGL) — 15% chain-wide globally.
- HP (Code: HPQ) — 15% in North America and Europe, meaningfully deeper in Asia.
- Intel (Code: INL) — Best near Santa Clara and Chandler, AZ.
- Oracle (Code: ORA) — Consistent across tech-heavy markets.

Comparing Marriott Corporate Rates to Other Discounts
Corporate codes aren’t always your best option. Here’s how they stack up:
| Discount Description | Estimated Savings | Booking Link |
| Military & First Responder | Save 15% (code XYD) | Book Here |
| AAA/CAA Discount | Save 5-10% | Book Here |
| Government Rate | Save 5-10% | Book Here |
| Senior Discount (62+ years) | Save 5-10% | Book Here |
vs. Marriott Breakaway Rates
If your company participates in the Marriott Breakaway program, you can access corporate leisure rates for personal travel—typically 10-30% off. This is a legitimate option for personal trips.
vs. Marriott STARS
For luxury properties, compare corporate discounts with Marriott STARS rates, which include benefits like complimentary breakfast, room upgrades, and hotel credits.
How to use the Marriott App to Compare Multiple Rates
There is a little-known trick that can help you compare multiple codes and rates at the same time when using the Marriott App. This trick is only available via the app on your phone or tablet, not on your laptop or PC, so please keep that in mind.
Here is how to do it:
Open the Marriott app on your phone or tablet. Enter your location and dates, then click the arrow to open the “Special Rates” section
Once you click on the special rates tab, you will have the option to compare various rates. To do so, go to the field that says “Add Corp/Promo Code” and add up to 4 of the corporate codes you want to compare.
Now, you need to check the box to the right for each rate type you want to compare. You can also check the box to save this for future searches.
The results will be displayed with the hotels offering the corporate rate and which is the best. As you can see from the example below, the best code might not be the same at every hotel in a region. The results in this case show that one of the hotels does not offer a corporate rate; two have the best rate with a Deloitte code, and one has the best rate with an Accenture code.
You can select your property and room from here to complete the booking process.
What Can Go Wrong (And How to Handle It)
Most corporate code bookings go smoothly, but here are the situations I’ve encountered and how to handle them.
The Code Doesn’t Show a Discount
Sometimes you’ll enter a corporate code and see rates that match or exceed the standard member rate. This usually means the property doesn’t participate in that specific corporate program, or their negotiated rate isn’t better than current public rates.
Try a different code or just book the member rate. Not every property honors every corporate code, and that’s normal.
The Rate Disappeared Between Search and Booking
Corporate rate availability can be limited. If you search, compare options, and then return 20 minutes later to book, the corporate rate might have sold out in the meantime. This is more common during high-demand periods or at properties with limited room inventory allocated to corporate rates.
Book quickly once you’ve identified your best rate, especially if it’s significantly better than alternatives.
You’re Asked for Verification You Can’t Provide
If you’re asked to verify eligibility at check-in and you can’t provide appropriate documentation, the hotel will reprice your reservation. Be polite, acknowledge the situation, and ask what rate they’ll charge instead.
In my experience, front desk staff usually apply the best available rate at that moment rather than penalizing you with rack rate. That said, during high-demand periods, even the “best available” rate might be substantially higher than your corporate rate.
The Corporate Benefits Don’t Apply
Some corporate codes include additional perks like free breakfast or parking. If these benefits don’t appear on your reservation or at check-in, mention it to the front desk. Sometimes the benefits are in the system but weren’t automatically applied—the desk can usually fix this immediately.
If the hotel says those benefits aren’t part of the corporate agreement, there’s not much you can do. Rate terms vary by company and property, so not all corporate codes include extras beyond the discounted room rate.
You Need to Cancel Within the Window
Corporate rates typically allow free cancellation until noon on arrival day, which is more generous than the standard 24-hour policy. However, make sure you’re within the cancellation window before trying to cancel—policies vary by rate type.
I’ve successfully canceled corporate rate bookings the morning of arrival without penalty dozens of times. This flexibility is one of the main advantages of corporate rates over prepaid promotional rates.
The Code Appears to Be Dead
If a code that previously worked now consistently returns no discount across multiple properties and dates, the underlying corporate agreement may have expired or been renegotiated. Morgan Stanley’s MOS code, for example, has been reported by readers as non-functional as of mid-2025.
When this happens, the code doesn’t come back — Marriott’s corporate sales team may have retired the account or moved it to Business Access by Marriott Bonvoy, their platform for small-to-medium businesses.
The Business Access by Marriott Bonvoy Alternative
If you run a small business or frequently book hotels for work but don’t have access to a large corporate code, Business Access by Marriott Bonvoy is worth exploring. Per Marriott’s own program materials, this program lets small-to-medium businesses book Marriott hotels at discounted rates (called “SMB Rates”), along with flights, rail, and rental cars, through a single travel management tool.
Per Marriott’s program terms, to qualify as an SMB you must be a valid legal entity (LLC, corporation, etc.) with a valid taxpayer ID, business license, or other form of government-issued corporate identification. Travel intermediaries, state-owned entities, and large companies already in Marriott’s deployed corporate portfolio are not eligible.
Per Marriott’s FAQ for the program, if your SMB has a locally-negotiated rate directly with a hotel, that rate will remain unchanged, and beginning early 2026, negotiated rates associated with an SMB’s unique rate code will be bookable via the Program booking tool and will qualify for Program benefits.
Frequently Asked Questions
Each discount is negotiated separately, so it often has different inclusions. Some offer just the reduced rate, while others can include free WiFi, shuttle transportation to the office, and flexible cancellation policies. To find out what is included in your rate, click on “rate details,” and the specifics of your rate will be displayed.
Yes. These discounted rates are considered “qualified rates” and are eligible to earn base points and any bonus points associated with a Marriott Bonvoy promotion.
Yes. As stated in the question above, corporate discounts are considered “qualified rates” and are eligible to receive the benefits of your Marriott Bonvoy elite status.
The largest consulting companies, such as Deloitte, Accenture, E&Y, etc, will offer the best “Chain-wide” corporate discounts. However, you may find a better rate associated with a major corporation in the area. For example, Procter & Gamble will likely have the best rates in Cincinnati because it is their headquarters location. Still, Deloitte will have a better chain-wide corporate discount outside of that region.
What Other Hotel Chains Offer Corporate Codes?
Most major hotel companies offer negotiated corporate discount codes. Here are guides for other chains:
- Hilton Corporate Codes
- IHG Corporate Codes
- Hyatt Corporate Codes
- Omni Hotels Corporate Codes
- Wyndham Corporate Codes
- Choice Hotels Corporate Codes
- Best Western Corporate Codes

What is the Marriott corporate code for Morgan Stanley? MOS is not valid. Thanks
Thanks for flagging. You’re right — readers have reported MOS is no longer functional as of 2025. The code appears to have been retired by Marriott’s corporate sales team. I’ve updated the article to note this.
