I've been meaning to write this post for a while, but kept putting it off because there are already plenty of referral-code posts around. Then a colleague recently asked me how the MariBank sign-up rewards actually work, including which accounts qualify and where to enter the referral code.
So instead of explaining everything from scratch again, I thought I'd put it all together here.
If you're considering opening a MariBank account, or you've already decided to sign up and are simply looking for a referral code, here's a quick breakdown of what you need to know.

If you already know which MariBank account you're applying for, you can simply use the code during registration. I've also included the details below if you want to understand how the rewards work.
I was actually quite late to MariBank. I already had accounts with my usual banks, so I wasn't particularly interested in opening another one at first.
What eventually caught my attention was the interest offered on the Mari Savings Account, along with the fact that the app is relatively straightforward to use. The referral rewards were also a nice incentive since I was already considering opening an account.
For me, it made more sense to take advantage of the promotion rather than sign up without a referral code.
MariBank's rewards vary depending on the product you're applying for. Based on the promotion available in August 2026, here's the breakdown:
S$8 cash reward
Available when you sign up for a standalone Mari Savings Account or the Mari Invest Bundle.
S$15 cash reward
Available when you sign up for the Mari Credit Card Bundle or Instant Loan Bundle.
Up to S$100 in card-related rewards
The New-to-Card reward can include S$30 welcome cashback plus a S$70 Shopee voucher pack, subject to the applicable promotion terms and eligibility requirements.
S$28 cash reward
For those running a business, MariBank also offers a referral reward when you open a Mari Business Account.
Keep in mind that promotional rewards can change. If you're reading this after August 2026, I'd recommend checking MariBank's latest promotion terms before signing up to confirm the current rewards and eligibility requirements.
This is probably the most important part.
During the application process, look for the field labelled "Referral / Promo Code?" and enter:

Make sure the code is entered before you submit your application.
Don't assume you can add the referral code later if you forget. Referral attribution is generally tied to the application process, so it's better to double-check that the code has been entered correctly before submitting.
In short:
Enter the code → Check that it's correct → Submit your application.
It only takes a few seconds, so there's really no reason to leave it until later.
Personally, I wouldn't open a financial account purely because of a referral reward.
I'd look at the account itself first: the interest rate, features, fees, eligibility requirements and whether you actually have a use for it. If MariBank already makes sense for you, then the referral reward is a nice extra.
If you're already considering opening a savings account, getting a new credit card or setting up a business account, there's little reason not to use an eligible referral code if it gives you an additional reward.
Just make sure you understand the applicable terms rather than signing up solely because of the headline reward.
No. There is no separate fee for entering a referral code.
Referral promotions are generally intended for eligible new customers or new product applications. If you already have a MariBank account, check the latest promotion terms to see whether you're eligible.
The reward may not appear immediately. The timing depends on the specific promotion and whether you've met all the qualifying conditions, so check the applicable terms for the expected reward timeline.
This depends on the specific MariBank products and promotion terms. Different products can have different qualifying conditions, so don't assume that every reward can automatically be combined.
If you're planning to apply for multiple products, it's best to check the latest official terms before proceeding.
If you're already planning to open a MariBank account, you might as well check whether you're eligible for the referral rewards before submitting your application.
