Kris+ Referral Code C379233: How to Claim Your Free $5 Sign-Up Bonus (Full Breakdown)

I kept seeing different posts about the Kris+ (Singapore Airlines) app claiming you get free miles, but leaving out exactly what you have to do to actually unlock the bonus!

​

I went straight to the official Kris+ terms to pull the current, live sign-up mechanic. Here is the no-nonsense breakdown of what you get today, plus my verified code: C379233 or Kris+ Referral Link

​

The Short Version

Download the Kris+ app, enter C379233 during your initial registration, and make a single transaction of at least $5 at any partner merchant. You will immediately be credited with 500 KrisPaymiles (worth exactly $5).

​

The Actual Rewards

Here is what you actually get as a new customer signing up today:

• The Sign-Up Gift: 500 KrisPay miles credited directly to your wallet.
• The Cash Value: 500 miles equals S$5, which you can use immediately to offset your next purchase at over 1,500 dining and retail stores in Singapore.
• The Earning Rate: Going forward, the app lets you earn up to 9 miles per S$1 spent.

3 Steps to Guarantee Your Bonus

If you miss step 3, you forfeit the bonus entirely.

1. Download the Kris+ by Singapore Airlines app from the Apple App Store or Google Play Store.
2. Tap to register. Stop here. The app will ask for a referral code during this initial sign-up screen. Enter C379233. (Existing KrisFlyer members can just log in, but still input the code when prompted).
3. The Activation Step: Within the app, make your first payment of at least $5 at any participating merchant (like dining, retail, or buying a voucher).
4. Your 500 miles will be credited automatically!

The #1 Mistake That Voids the Bonus

Unlike some other bank promos where simply opening the account gets you the reward, Kris+ requires a minimum spend of S$5. If you download the app and enter the code but never actually use the app to pay for a $5 coffee or meal, the $5 bonus will never unlock.

FAQ

Is this code currently active? Yes, this code (C379233) is active and I've personally verified it's valid for the current 2026 promotional period.

​

What happens if I forget to enter the code at the start? Unfortunately, referral codes must be entered during the first registration/login screen. There is no way to add it retroactively.

​

Should I keep the miles on Kris+ or transfer them? If your goal is free flights, you can transfer miles earned on Kris+ via the partner merchants directly to your main KrisFlyer account at a 1:1 ratio. Usage Warning tip! Just make sure to do it within 21 days of earning them!
