(Free Welcome Vouchers) Chagee Referral Code : 4WbYiGB

New to Chagee? Use referral code 4WbYiGB when you sign up on the Chagee app in Singapore and you’ll get two welcome vouchers stacked into your account: a 50% off voucher and a Buy 3 Get 1 Free voucher. The code works for new users only and the vouchers land in your app wallet the moment you finish registration. If you’ve been eyeing the Jasmine Green Milk Tea queue at Raffles City, Jewel, or NUS, this is the cheapest way to try it.

What Is Chagee and Why Use It

Chagee (霸王茶姬) is a Yunnan-born premium tea chain that has aggressively expanded across Singapore since 2024. Unlike most bubble tea brands, Chagee positions itself closer to a contemporary teahouse — think loose-leaf brewed tea, fresh milk, and zero artificial creamer in the signature drinks.

The brand now operates 35+ outlets island-wide, including Jurong Point and Tampines West CC, which are open 24 hours. Other key locations include Jewel Changi Airport, VivoCity, Plaza Singapura, Suntec City, Orchard Gateway, Raffles City, and NUS Yusof Ishak House (Southeast Asia’s first Chagee Signing Store).

The Chagee app is what unlocks the savings layer. It lets you:

• Order ahead and skip the queue (a real benefit during lunch rush at CBD outlets)
• Earn Tea Leaves (Chagee’s reward currency) on every purchase
• Climb membership tiers — CHA Seeker → CHA Explorer → CHA Pioneer → CHA Master — for monthly perks
• Redeem a free birthday drink
• Link your yuu Rewards ID for extra cashback when paying with DBS yuu or PAssion POSB Debit cards

Without the app, you’re just paying full price.

Chagee Referral Code — What You Get

Use the Chagee referral code 4WbYiGB at sign-up and your account is credited with the standard new-user welcome bundle:

On a typical $7.50 signature drink, the 50% voucher alone saves you around $3.75. Stack the Buy 3 Get 1 Free on a separate order and you’re effectively saving another ~$7.50. Realistic total value: $10–$12 in savings depending on what you order.

The voucher amounts and pairing have remained consistent through 2025 and into 2026, though Chagee occasionally rotates the secondary voucher (sometimes a Members’ Day discount instead of Buy 3 Get 1 Free). What you actually see in your wallet depends on which campaign is live the day you sign up.

How to Use the Chagee Referral Code (Step-by-Step)

The flow takes about 90 seconds. Here’s exactly what to do:

1. Download the Chagee app. Search “Chagee” on the App Store or Google Play, or use the official links above. Make sure the publisher shows as Chagee — there are lookalike apps.
2. Open the app and tap “Sign Up”. Use your Singapore mobile number. You’ll get an SMS OTP.
3. Enter the referral code: 4WbYiGB when prompted on the registration screen. If you miss this step, the vouchers won’t credit and Chagee customer service generally won’t backdate it.
4. Verify the OTP and complete your profile. Set your birthday correctly — you’ll want this for the free birthday drink later.
5. Check your voucher wallet. Tap the profile icon → Vouchers. The 50% off and Buy 3 Get 1 Free vouchers should appear immediately. Note the expiry date (usually 30 days from issue).
6. Order your first drink. At checkout, tap “Use Voucher” and select the 50% off voucher. Pay via the app — credit card, NETS, or in-app wallet top-up. Pick up at any outlet or have it delivered via GrabFood (link your Chagee account inside the app for points to stack).

If the code field doesn’t appear on your sign-up screen, log out, reinstall the app, and try again — it’s a known glitch on older Android builds.

Eligibility & Terms You Should Know

Be honest with yourself before signing up — these are the real limitations:

• New users only. The Chagee referral code only works for first-time app registrants in Singapore. If your phone number was previously used on the Chagee SG app (even briefly), the code will silently fail.
• Singapore market. The code 4WbYiGB is tied to the Singapore app. The Malaysia, Thailand, and China Chagee apps run separate referral programmes and codes are not cross-redeemable.
• Voucher expiry. Welcome vouchers typically expire 30 days from issue. Don’t sit on them.
• Minimum spend may apply. The 50% off voucher usually has no minimum, but the Buy 3 Get 1 Free voucher requires all four drinks in one order, applied to the cheapest one.
• Not stackable with other promos. You can only use one voucher per transaction. Don’t expect to stack the 50% off with a Members’ Day discount.
• Code must be entered at sign-up. It cannot be applied retroactively to an existing Chagee account.

For full terms, refer to the official Chagee Singapore site.

Is the Chagee Referral Bonus Worth It?

Short answer: yes, if you were going to try Chagee anyway.

The maths is straightforward. Chagee’s signature drinks sit between $6.50 and $8.50 — pricier than Koi or LiHO but cheaper than a specialty café latte. The 50% off voucher essentially gives you a no-risk first try at around $3.50, which is below hawker drink prices for a much larger, branded cup.

Where it becomes genuinely valuable is the Buy 3 Get 1 Free voucher. If you work in the CBD or have a habit of ordering for the office, this knocks roughly 25% off a four-drink order — about $7–$8 in real savings.

Compared to other Singapore F&B referral programmes — most of which offer a single $3–$5 voucher with minimum spend conditions — Chagee’s welcome bundle is on the more generous end. The catch is it’s voucher-based, not cash credit, so the value only materialises if you actually drink Chagee.

If you’re a one-cup-a-month casual drinker, you’ll capture roughly $10 of value over the 30-day window. Heavy drinkers and office orderers will easily clear $15+.

FAQ

How long does the Chagee welcome bonus take to credit?

Instantly. The vouchers appear in your in-app wallet the moment you finish registration. If they don’t show up within five minutes, force-close the app and reopen it.

Can I use the Chagee referral code if I already have an account?

No. The code only works during initial sign-up. If you already have a Chagee Singapore account tied to your mobile number, the system will block the code from applying.

How much can I save with the Chagee new user promotion?

Realistically, between $10 and $15 across your first two orders, depending on which drinks you choose. Heavy orderers using the Buy 3 Get 1 Free voucher on premium drinks will save more.

Do Chagee welcome vouchers have a minimum spend?

The 50% off voucher generally has no minimum. The Buy 3 Get 1 Free voucher requires you to order four drinks in a single transaction; the discount applies to the cheapest of the four.

Can I use my Chagee welcome vouchers on GrabFood or foodpanda?

No. Welcome vouchers issued through the Chagee app are app-exclusive. They cannot be redeemed on third-party delivery platforms. However, you can still earn Chagee membership points on GrabFood orders if you’ve linked your account.

What happens if I forget to enter the referral code at sign-up?

The welcome vouchers will not be credited and Chagee customer service typically does not backdate referral rewards. The workaround — if you’ve genuinely just signed up — is to uninstall, sign out, and try again before placing any order, but this only works if you haven’t transacted yet.

Can foreigners and tourists use the Chagee referral code in Singapore?

Yes, as long as you have a Singapore mobile number to receive the OTP. Tourists on short stays may struggle here, since the app requires SMS verification on a local line.

How do I check my Tea Leaves balance and membership tier?

Open the Chagee app, tap the profile icon, and your Tea Leaves balance and current tier (CHA Seeker, Explorer, Pioneer, or Master) display at the top. You earn Tea Leaves on every qualifying purchase.

Is there a Chagee referral programme for referrers in Singapore?

Yes. Once you’re a registered Chagee user, you can find your personal referral code under “Invite Friends” in the app. Successful referrals earn you free drink vouchers and Tea Leaves.

Can I link my Chagee account with yuu Rewards for extra cashback?

Yes — and you should. Linking your yuu Rewards Club ID with the Chagee app stacks rewards when you pay with the DBS yuu Card (up to 18% cashback or 10 miles per S$1) or PAssion POSB Debit Card (up to 9% cashback or 5 miles per S$1).

Ready for your first sip? Download the Chagee app, enter referral code 4WbYiGB at sign-up, and your welcome vouchers will be waiting in your wallet before you’ve even decided between the Jasmine Green Milk Tea and the BoYa. Singapore new users only — and once you’ve used your vouchers, your own referral code unlocks inside the app for the next round of savings.
