What is the OKX referral code?

The OKX referral code is a short code you enter once, during registration, in the field labelled “Referral code (optional)”. Ours is BONUSCODE20. It links your new account to a referral, so OKX applies a permanent 20% trading-fee rebate and makes you eligible for the welcome bonus. You cannot add it after the account is created, so enter it before you finish signing up.

OKX referral code benefits: what do you get for BONUSCODE20?

  • A permanent 20% discount on trading fees
    The code sets a 20% rebate on your trading fees for the lifetime of the account. OKX shows it as “20% rebate rate applied” the moment you enter BONUSCODE20. The more you trade, the more the discount is worth.
  • A welcome bonus of up to €400
    New accounts also get the OKX welcome bonus: deposit and trading tasks worth up to €400, plus the separate 8% deposit bonus that pays a percentage of what you fund the account with. OKX sets both and changes them with each campaign, so check the full OKX bonus terms before you deposit.

Where to find the OKX referral code?

OKX does not publish a list of referral codes, so every code you see comes from an existing user or from a partner site. People mean three different places by this question, so here are all three.

Where to get a code you can use

From a page like this one. Ours is BONUSCODE20. Because OKX runs no public directory of codes, there is nothing to browse and nothing to compare except one number: the rebate rate a code applies. OKX itself prints that number under the field before you finish signing up, which makes it the only claim on this page you do not have to take on trust.

Where the field is during registration

On the OKX sign-up page, directly beneath the email address field, labelled “Referral code (optional)”. The screenshot below is that page. If you cannot see the field, it is collapsed behind a small arrow or link next to the email box, so expand it before you press Sign up.

Where to find your own code, to invite other people

Once your account exists, open your profile in the OKX app or on the website and go to the referral or invite section. That code is yours to share. It is a different thing from the code you entered at registration, which is fixed to your account and cannot be swapped later.

How to use the OKX referral code

Enter the code during registration, in four steps:

  1. Open the OKX sign-up page and enter your email address (or phone number).
  2. Find the “Referral code (optional)” field and type BONUSCODE20.
  3. Check that OKX shows “20% rebate rate applied” with a green tick, then finish creating your account.
  4. Verify your identity (KYC), then open the OKX app to join the campaign and claim the welcome bonus.

How does the 20% fee discount work?

OKX charges a small percentage on each trade. The referral code applies a 20% rebate on that fee, so you pay 80% of the standard rate on every trade, for as long as you use the account. Because it is a percentage, the saving scales with your volume: the more you trade, the more you keep. Your exact fees depend on your OKX fee tier.

How do you claim the welcome bonus?

Register with the code, complete identity verification, then open the OKX app and join the active welcome campaign before your first deposit, so the tasks are tracked from the start. The current EU ladder pays €5 for a first trade and rises to €400 at the top rung, with a separate 8% bonus on your net deposit. Amounts and tasks are set by OKX and differ by campaign and country, so read the full OKX bonus terms for the current tiers, dates and payout schedule.

The code works for new OKX accounts worldwide, not just in the EU. For EU/EEA users, OKX Europe Limited is CASP-licensed under MiCA by Malta Financial Services Authority (MFSA) (authorised 27 January 2025) and appears in the official ESMA register, so it may legally serve EU clients.

Frequently asked questions

What is the OKX referral code?

If you are looking for the best OKX code: use “BONUSCODE20” - it is verified and gives the maximum bonuses. Enter the code in the “Referral code (optional)” field during registration to get a permanent 20% trading-fee rebate and become eligible for the welcome bonus.

What is the best OKX referral code in 2026?

There is no officially ranked “best” code. Codes differ in one thing: the rebate rate they apply to your trading fees. BONUSCODE20 applies 20%, and OKX confirms it on the sign-up screen with “20% rebate rate applied”. Compare that number rather than the marketing around a code, and check it before you finish registration, because the rate cannot be changed afterwards.

How do you get a free OKX referral code?

Every referral code is free. You never pay for one: copy a published code, such as BONUSCODE20, and paste it into the “Referral code (optional)” field while creating your account. Once your account exists, OKX also gives you your own code in the app, which you can share with other people.

Does OKX have any promo codes available?

OKX has no checkout-style promo code box. The equivalent is the “Referral code (optional)” field at registration, where BONUSCODE20 sets a permanent 20% fee rebate. Anything else OKX offers, such as deposit or welcome campaigns, is claimed by opting in inside the app, not by typing a code.

How do you get free USDT on OKX?

Not from the referral code. BONUSCODE20 lowers your trading fees by 20%, but it does not pay out USDT. Free crypto on OKX comes from separate, time-limited campaigns that you opt into in the app after registering and passing KYC, and OKX Europe pays those rewards in USDC rather than USDT. Campaign terms change often, so confirm them on OKX's own campaign page before you deposit.

Does OKX have a welcome bonus?

Yes, but it is not paid out automatically. After you register with a referral code and pass identity verification, you open the OKX app, join the welcome campaign that is live in your region and complete the tasks it lists, usually a qualifying deposit and a trade. The amount and the deadline are set by OKX and change from campaign to campaign, so read the terms in the app before you deposit.

Do I have to enter the code manually?

Yes. Type BONUSCODE20 into the “Referral code (optional)” field on the OKX sign-up screen. OKX confirms it with “20% rebate rate applied” and a green tick.

Can I add the referral code after signing up?

No. The code can only be applied during registration. If your account already exists without a code, you cannot add it afterwards.

How much can I save on fees?

You pay 20% less on every trading fee, for the life of the account. Because it is a percentage, the more you trade, the larger the total saving.

Does the OKX referral code work outside the EU?

Yes. The code works for new OKX accounts worldwide. Separately, OKX Europe is CASP-licensed under MiCA for EU/EEA clients.

Is it safe to use an OKX referral code?

Yes. A referral code is a standard OKX feature. It does not give anyone access to your account, and it only sets your fee rebate and bonus eligibility.
