# AT&T Corporate Code N0099999 at Omni Dallas Hotel: Real Savings at One of Dallas's Premier Properties
If you are an AT&T employee heading to Dallas for business, you are already sitting on one of the more quietly useful hotel perks in the corporate travel world, because the Omni Select Guest corporate code N0099999 delivers genuine, calculable savings at a hotel that genuinely deserves your attention. Dallas is a city that punishes the unprepared traveler with wildly variable rack rates, especially around major conventions at the Kay Bailey Hutchison Convention Center, and knowing your corporate rate before you book can be the difference between a $170 night and a $280 one on the exact same room.
## The Property
The Omni Dallas Hotel rises 23 stories at 555 S Lamar Street in the heart of downtown Dallas, connected by a sky bridge directly to the Kay Bailey Hutchison Convention Center, which makes it the single most convenient option for any AT&T employee attending a trade show, industry conference, or corporate summit in the city. The hotel holds a 4.5-star rating across nearly 10,000 guest reviews, which is a number large enough to trust, and the property earns that rating through consistent execution rather than flashy gimmicks.
The 1,001 guest rooms and suites are finished in a warm Texas-influenced palette, with floor-to-ceiling windows that frame either the Dallas skyline or the historic Reunion Tower, and standard rooms run a generous 400 square feet, which gives business travelers actual room to spread out a laptop, review documents, and feel like a human being rather than a sardine. The beds use Omni's signature pillow-top mattresses with high-thread-count linens, and the bathrooms feature oversized walk-in showers alongside deep soaking tubs in many room categories.
Amenities on property include the rooftop pool deck on the 10th floor with panoramic downtown views, a well-equipped fitness center, and Bob's Steak and Chop House, one of Dallas's most respected steakhouses operating right inside the hotel, which means you can close a dinner deal without ever summoning a rideshare. The Omni Dallas also houses Texas Spice, a casual all-day dining restaurant with a breakfast buffet that is genuinely excellent, featuring locally sourced ingredients and made-to-order egg stations.
The location puts you within easy walking distance of the AT&T Discovery District, the Sixth Floor Museum at Dealey Plaza, the Dallas Arts District, and the Perot Museum of Nature and Science, so if your schedule opens up for an afternoon, you have real options within 15 minutes on foot. Dallas Love Field is about 20 minutes by car and DFW International is roughly the same distance depending on traffic, both accessible by rideshare or the hotel's car service.
## Positive Return Calculation
The Omni Select Guest program awards points on a tiered basis, and while the earn rate officially varies by promotion and status level, a reliable baseline for calculating value is 10 points per dollar spent on qualifying room charges. At a redemption and valuation rate of 0.8 cents per point, here is how the AT&T corporate code N0099999 stacks up across three realistic rate scenarios at the Omni Dallas Hotel.
| Rate Tier | Rack Rate | Corporate Rate | Points Earned | Point Value | Net Cost | Savings |
|-----------|-----------|----------------|---------------|-------------|----------|---------|
| Budget | $170 | $145 | 1,450 pts | $11.60 | $133.40 | $36.60 |
| Mid-Range | $280 | $238 | 2,380 pts | $19.04 | $218.96 | $61.04 |
| Premium | $450 | $383 | 3,830 pts | $30.64 | $352.36 | $97.64 |
The math here is straightforward and worth walking through once so it sticks with you. At the mid-range tier, the corporate rate of $238 saves you $42 off the $280 rack rate right away, then you earn 2,380 points at 10 points per dollar, which at 0.8 cents per point equals $19.04 in redeemable value, bringing your true effective cost down to $218.96 and your total savings against rack rate to $61.04 on a single night. Extended over a three-night business trip at the mid-range tier, you are looking at over $183 in combined savings, which is a number worth printing out and showing your travel manager.
## How to Book with Code N0099999
Booking through the Omni Select Guest portal with your corporate code is a straightforward process that takes about four minutes once you know the steps.
1. Go to omnihotels.com and click the booking bar at the top of the homepage.
2. Type "Dallas" in the destination field and select the Omni Dallas Hotel from the dropdown results.
3. Enter your check-in and check-out dates, then look for the field labeled "Special Rate" or "Corporate/Promotional Code" directly beneath the date selectors.
4. Enter the code N0099999 in that field exactly as written, with no spaces.
5. Click Search or Check Availability, and the results page will display your AT&T corporate rate alongside the standard rates so you can confirm the discount is applied before you proceed.
6. Select your room type, proceed to the guest information page, and either sign into your existing Omni Select Guest account or create one to ensure points post correctly to your profile.
7. Complete the booking and save your confirmation number, because the corporate rate is attached to that specific reservation and you will want that number if any rate discrepancy appears at check-in.
Always verify at check-in that the corporate rate on your folio matches what you booked, and carry a screenshot of your confirmation as a backup.
## Stacking Strategy
The corporate code is a starting point, not the ceiling, and AT&T travelers who take a few extra minutes to stack additional benefits on top of code N0099999 consistently extract more value from each stay.
Omni Select Guest members who reach Select or Black status earn bonus points multipliers of 25 to 50 percent on top of the base earn rate, meaning that a Black member paying the $238 corporate rate earns closer to 3,570 points per night instead of 2,380, pushing the point value up to roughly $28.56 and the effective net cost down to around $209.44. If you stay at Omni properties more than a few times per year, prioritizing status in this program before your Dallas trip is worth planning around.
Pair your stay with a Chase Sapphire Preferred or Chase Sapphire Reserve card if you hold one, because hotel stays booked directly with the property often qualify for 3x Ultimate Rewards points on travel purchases, adding another layer of return on top of your Omni points. At the mid-range corporate rate of $238, that is an additional 714 Chase points worth roughly $7.14 at 1 cent per point or closer to $10.71 if you transfer to airline partners, which is not a life-changing sum but it is free money sitting on the table.
Watch the Omni Select Guest promotions page in the months leading up to major Dallas events like the Dallas Market Center trade shows or big NFL weekends, because Omni regularly runs bonus point promotions offering double or triple points on qualifying stays, and these stack on top of corporate rates without restriction in most cases.
## Bottom Line
The AT&T corporate code N0099999 at the Omni Dallas Hotel delivers a consistent 10 to 15 percent discount off rack rates at a genuinely well-regarded downtown property, and when you add in the points earned at 0.8 cents per point, a typical mid-range business stay produces over $61 in total savings against what any leisure traveler walking in without a code would pay. For AT&T employees who travel to Dallas with any regularity, building this code into your booking routine alongside an active Omni Select Guest account is one of the simplest ways to make your travel budget work harder without changing a single thing about where you stay.
