The current OKX referral code is 2027BIG. Enter it on the sign-up form and you get a 20% rebate on trading fees plus access to welcome rewards of up to 5,000 USDT.
You can't add the code after the account is created — not even through customer support.
One thing to know before you compare offers: 20% is the ceiling OKX allows a partner to give. In the partner dashboard the invitee's rate is a field capped at 0-20% — there's a screenshot of that screen at the end of this page. Anything advertised as a 30% or 50% OKX referral discount is a number the platform can't produce.
Where to enter the OKX referral code
- Open the OKX sign-up page.
- Select your country.
- Enter your email.
- Just below, type 2027BIG in the "Referral code (optional)" field. A green checkmark appears with the line "20% rebate rate applied" — the code is accepted and the discount is locked in.
- Click "Sign up" and finish registration with the 6-digit code.
How to use the referral code's rewards
After identity verification (KYC), the following become available:
- 20% rebate on trading fees. Applied automatically after KYC — the sign-up screen confirms the rate the moment the code is accepted. For anyone trading actively over a long horizon this saving outweighs the welcome bonus.
- Trading bonus up to 5,000 USDT. Credited for deposits and for meeting trading-volume conditions. Plenty of sites still quote a 10,000 USDT maximum. The current sign-up offer is 5,000 USDT — that's the number on the campaign screen above. Active tasks live in the "Campaign Center", and you claim the reward in "My Rewards". It can land as a crypto airdrop, a trading bonus, a rebate card voucher, a contract voucher, or an Earn APR boost.
On my own account, "My Rewards" shows 553 USDT accumulated over six years of trading — one active account, not a typical result. I never chased the tasks: registered, passed KYC, traded at my own pace.
Rewards vary by region. The 20% rebate applies wherever OKX operates, but the bonus package attached to it differs by market and campaign — what you'll actually get is on the sign-up screen and in "Welcome Rewards" before you finish registering. If the rebate line and a bonus appear there, the offer is live for your account.
How to save more on trading?
On top of the 20% from the code, holding OKB adds its own discount — roughly 10% with a small balance, up to 40% at larger holdings. The two apply in sequence, not in sum: a 0.10% base fee goes to 0.08% with the code, then to 0.048% at the top OKB tier. The exact rate depends on how much you hold, so check your fee tier in the account before counting on the number. The usual token-price risk applies: buying OKB purely for the discount only makes sense if you'd hold it anyway.
How we keep the OKX code current
Every month we run three checks:
- We log into the partner dashboard and confirm that 2027BIG is still linked to our account and active.
- We open the OKX site without logging in and walk through the new-user flow up to the code field, and check that "20% rebate rate applied" appears below it.
- We follow campaign announcements through OKX's official channels — new bonus information shows up on Telegram, on the website, and on X.
That way we only publish codes that actually work.
How to invite via the code — and is it worth it?
OKX pays you for inviting new users, in two formats sized for different traffic volumes.
- Referral Program. The basic tier: when someone signs up through your link and makes a first trade of at least 50 USDT, 10 USDT lands in your account — up to three times a month, so 30 USDT is the cap. Enough to test the format among friends.
- Affiliate Program. Aimed at people with a large audience: your share of the fees your invitees pay grows with their combined monthly volume. The discount you set for an invitee tops out at 20%, as the screenshot below shows. The honest catch is the same as everywhere: it only pays off with an active audience.
Creating a referral link in the OKX partner dashboard: the invitee's rate can't go above 20%.
