OKX 2026 Referral Code Full Tutorial: Easily Get 20% Trading Fee Rebate

The biggest mistake is opening OKX in a new browser tab without clicking the affiliate link. The referral code and the link work together; OKX uses the link to pre-fill the code field and to record the correct promotional tier. If you create an account without the link, the code field may not appear at all, or the system may not associate your account with the 20% rebate plan.

Open the official OKX registration page directly from this article or from the saved link. You should see the standard email/phone registration form. Do not use a pre-existing account to try to claim the code later, because OKX only applies the referral relationship during the initial sign-up flow. A clean browser, no cached OKX session, and the correct link are the first three checks before you type anything.

This rule exists because the referral program is an anti-abuse mechanism: it rewards new users who are genuinely introduced to the platform. In exchange for bringing that new user, the platform gives you a permanent discount. The system cannot verify a referral if you add a code after you have already deposited, because the fee-rebate ledger would have already accepted a different default rate.

On the registration form, after you enter your email address and create a password, look for a field labelled Referral Code, Invitation Code, or Promo Code. On the mobile app, this field sometimes sits behind a small toggle that says “Have a referral code?”. Tap that toggle and paste exactly: 31999414.

Do not add spaces, letters, or punctuation. Digits only: 3-1-9-9-9-4-1-4. If you copy the code from a web page, make sure you did not accidentally copy a trailing space or hidden character. The field is case-sensitive in some older app versions, and the order of digits matters. After entering the code, the page should show a confirmation message such as “Referral applied” or “You are eligible for a fee discount”.

If the code field is missing, go back one step and check that you used the correct affiliate link. Some users open the generic OKX homepage and then search for “join OKX”, which strips the referral parameter. The safest method is to use the link provided in this article, then register in the same session without closing the tab.

Entering the code is not enough by itself. OKX requires identity verification before you can trade, withdraw, or receive most fee rebates. Complete at least Level 1 KYC with a government-issued ID and a facial scan. Level 2 verification is usually required for higher withdrawal limits and full derivatives access, and it also confirms that you are eligible for the permanent 20% rebate programme attached to code 31999414.

During the verification process, use the same legal name that appears on your ID. Do not use a nickname, and do not upload a cropped or expired document. The system usually approves Level 1 in under 10 minutes, but Level 2 may take a few hours during peak periods. Once approved, the platform automatically applies your discount to eligible spot and derivatives trades.

If you skip KYC and go straight to deposit, OKX may allow a limited deposit but will freeze trading and withdrawals. That creates an unnecessary support ticket. Finish the verification before depositing funds, because a frozen account cannot benefit from any fee rebate.

After KYC approval, deposit a small amount of USDT or another supported asset. The minimum deposit can be as low as a few dollars for testing purposes. Before you place a real order, go to your account settings and open the Fee Rates page. On the web version, hover over your profile icon and click “Fee rates”. On the app, go to “Profile”, then “Fee rates”.

You should see a spot taker rate of approximately 0.08% for ordinary users, not the full 0.10%. If your account is associated with the referral code 31999414, there may also be a separate rebate line or a note in the “Referral program” tab. The 20% rebate is typically calculated on the actual fees you pay after any volume-based tier discount. For example, if you are a VIP 1 user with a lower base fee, the referral rebate still applies on top of that lower fee, compounding the benefit.

If your fee page still shows 0.10% with no rebate marker, do not deposit more. Contact OKX support immediately and provide the referral code and the email used for registration. In most cases, they can retroactively attach the code within the first 24 hours, but any trades placed before that may not be eligible for the rebate. Verify first, then trade.

Once you trade, the 20% rebate is not always displayed in the interface in a dramatic way. It usually appears as a small credit line in your fee deduction, or as a periodic USDT rebate depending on the current promotion. To confirm it is active, make one small spot trade, then check the fee breakdown in your trade history. If the fee is reduced from the standard rate, the referral relationship is working.

You can also go to the Referral or Rewards section and look for a banner that says “You joined with code 31999414”. That banner confirms the lifetime status. If the banner is absent but your fee rate is lower, the rebate may still be active; the display can vary by region and app version.

Keep a simple monthly log: volume traded, fee paid, estimated rebate. This is not only useful for tax records but also helps you spot any unexpected change in the fee tier. Because the discount is permanent, you do not need to re-enter the code every year. It stays linked to your account unless OKX updates its fee policy globally, which is rare and always announced.

Risk 1 - Market volatility: Cryptocurrency prices can fall by 30% or more in a single day. The 20% fee rebate does not reduce the price risk of your assets. Never deposit money you cannot afford to lose entirely.

Risk 2 - Regulatory and jurisdiction risk: OKX restricts services in certain countries and may change its list of supported regions. Before completing KYC, confirm that using OKX is legal in your location. A referral code does not provide legal coverage.

Risk 3 - Fee programme adjustments: OKX generally honours referral discounts once linked to an account, but exchange fee tiers, VIP levels, and promotional conditions can be modified with short notice. Always re-check your fee page if the platform announces a global fee update.

Risk 4 - No financial advice: This tutorial explains how to enter the OKX referral code 31999414 and understand the 20% rebate. It is not an endorsement of any coin, leverage product, or trading strategy. You remain solely responsible for your own trading decisions.
