The OKX referral code for 2026 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.
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.

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.
The ladder on the campaign screen, step by step:
| Tier | What it takes | Reward |
| Task chain | deposits and first trades, one step at a time | 10 → 20 → 30 → 100 → 450 USDT |
| VIP 1 | trading volume at the VIP 1 level | 3,000 USDT |
| VIP 2 | trading volume at the VIP 2 level | 5,000 USDT |

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.
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 it compares
OKX doesn't win on the welcome ceiling, and it isn't trying to. Where it stands apart is the second discount: OKB can cut more than the code itself, and at the top OKB tier the combined spot rate ends up below what Bybit, KuCoin or Binance reach with their own tokens.
| Condition / Exchange | OKX | Bybit | KuCoin | Binance |
| Welcome rewards | up to 5,000 USDT | up to 35,140 USDT | up to 11,000 USDT | up to 600 USDT |
| Referral discount | 20% | none | 20% | 20% |
| Native-token discount | OKB: up to 40% | — | KCS: 20% | BNB: 25% |
Can anyone give you more than 20% off on OKX?
No. 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%, and that's the screen below. Anything advertised as a 30% or 50% OKX referral discount is a number the platform can't produce. What can go past 20% is your own OKB balance, and that has nothing to do with the code.

Creating a referral link in the OKX partner dashboard: the invitee's rate can't go above 20%.
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.
The date in the card at the top of the page is the last of those checks.
Why the rebate or bonus didn't arrive
| What you see | Why | What to do |
| No green checkmark and no "20% rebate rate applied" line | the code wasn't accepted, usually a typo | retype 2027BIG before you press "Sign up"; after that the field is gone for good |
| The rebate line showed, but "My Rewards" is empty | KYC not passed yet | pass identity verification, the tasks unlock after it |
| The welcome bonus on your screen is smaller than 5,000 USDT | the bonus package differs by market and campaign, the 20% rebate doesn't | check "Welcome Rewards" before you finish registering: what's listed there is what your account gets |
| A task is done, but nothing was credited | rewards aren't automatic | claim it in "My Rewards"; it may land as an airdrop, a voucher or an APR boost, not as cash |
| The fee rate doesn't match the OKB discount you expected | OKB tiers depend on how much you hold | check your fee tier in the account before counting on the number |
FAQ
What is an OKX referral code?
It's a partner code the sign-up form asks for right under the email field. It ties the new account to a partner; in return OKX pays you back part of every trading fee and opens the welcome tasks. Register without one and you trade at the full rate.
Can I add the code after registration?
No. OKX has no such option, and support won't attach it either: the field exists only in the sign-up form.
Is the referral code the same as an invite code or promo code?
Yes. OKX's own form says "Referral code (optional)"; invite code and promo code are what other sites call it. 2027BIG goes in that field under any name.
