As of early 2026, the specific registration codes for IHG "Fast Track" promotions frequently change, but the current active offer for 2025/2026 often utilizes code 54820 or 40154 for targeted corporate "Stay to Diamond" challenges. These promotions typically allow members to earn Diamond Elite status through December 31, 2026, by completing 8 to 10 qualifying nights within a 90-day window after registration. It is important to note that these "Straight to Diamond" offers are often "targeted," meaning they are officially intended for employees of specific corporate partners (like IBM or Deloitte) or members who received an invitation via email. To register, you must log into your IHG One Rewards account on the official "Offer" page and enter the code. If successful, your status will instantly reflect the "Challenge" state, and once the night requirements are met, your Diamond benefits—including free breakfast, 100% bonus points, and suite upgrades—will be locked in for the remainder of the 2026 calendar year.

The IHG “Straight to Diamond” promotion is not a single, always-available code. It is a targeted offer that appears periodically, and the eligibility and code are unique to each member.

Here’s what you need to know:

1. It’s Targeted & Invite-Only

• You must receive a direct invitation from IHG (via email or see it in the “Offers” section of your IHG One Rewards account).
• There is no universal public code that works for everyone.
• If you weren’t targeted, you typically cannot enroll.

2. Typical Promotion Structure

When it runs, the offer usually requires you to: Enroll with your unique code/link. Complete a certain number of paid nights (e.g., 10-15 nights) within a specified period (e.g., 3-4 months). Upon completion, you are instantly elevated to Diamond Elite status, which is then valid for the remainder of the current year and the entire following year.

3. How to Check if You’re Eligible

• Log in to your IHG One Rewards account on the website or app.
• Navigate to the “Offers” or “My Offers” section.
• Check your email inbox (and spam folder) for messages from IHG One Rewards.
• Promotions are often targeted based on your past travel patterns (e.g., infrequent stays or stays with competitors).

4. Current Alternative: The IHG One Rewards Premier Credit Card

If you are not targeted for “Straight to Diamond,” the most reliable way to get Diamond status is through the IHG One Rewards Premier Credit Card (issued by Chase in the U.S.). It grants automatic Diamond Elite status
