MariBank referral code

MariBank is Sea Group's digital bank in Singapore — the same company behind Shopee. There are no branches and no minimum balances; everything runs through the app, and deposits are SDIC-insured up to S$100,000, the same protection you get at any local bank.

What the referral gets you

Enter the code 4WWP19BW in the "Referral / Promo Code" field when you apply for your first MariBank product:

• S$15 cash — open a Mari Savings Account or a Mari Invest bundle
• S$20 cash — open a Mari Credit Card bundle (or an Instant Loan bundle)

The cash is credited to your Mari Savings Account on a successful application. You get one bundle reward, not both — so if you want the credit card anyway, apply for that bundle first and take the S$20.

On top of the referral

New MariBank customers are separately eligible for up to S$80 more: S$30 welcome cashback on the Mari Credit Card if you spend S$300 (excluding Shopee) within 30 days of approval, plus a S$50 Shopee voucher pack. New customers can also lock in a promotional 2.88% p.a. for one month on a Mari Fixed Deposit of S$5,000–S$50,000.

How to claim

1. Download the MariBank app and start an application for any personal banking product.
2. Enter 4WWP19BW in the "Referral / Promo Code" field before you submit.
3. Complete the application. The cash lands in your Mari Savings Account soon once it's approved.

The fine print

• Sign up by 31 July 2026. The promotion is capped at the first 10,000 successful referrals, so earlier is safer.
• The reward applies to your first eligible product only — it does not stack across bundles.
• Existing MariBank customers don't qualify.

Worth it if

You were going to park spare cash or try the Mari Credit Card anyway — this is free money for typing a code.
