Go to the OKX app on your phone or visit the official OKX website. Complete two-factor authentication if prompted. Make sure you are logging into your main account, not a sub-account or a trading bot account. Referral bindings are attached to the main account entity. If you only manage a sub-account, you may see linked permissions but not the original referral status.

After login, proceed to the profile area. On mobile, tap the profile icon in the top-left corner. On web, click the avatar in the top-right corner. Do not skip this because the referral status is not shown on the trading dashboard by default.

On the mobile app, look for “Rewards Hub,” “Referral,” “Invite Friends,” or “My Referrer.” On the web platform, you may find it under “More” or “Rewards.” In some regions the menu is called “Commission Rebate” or “Fee Discount.” The exact label depends on your app version, but the logic is the same: you are looking for the area that displays your linked inviter or referral details.

If you see a screen with two tabs—one for inviting friends and one for your own rebate—switch to the tab that says “My Rebate,” “My Referrer,” or “My Inviter.” This is where OKX shows whether your account is bound to a referral code.

Your goal is to see the exact code 31999414 listed under your referrer or inviter information. If the field displays that number, and the status shows “Active,” “Effective,” “Bound,” or “Success,” your account is correctly linked to the lifetime 20% commission rebate. Some versions also show a percentage under the code, such as “20% fee discount” or “20% rebate.” That is the strongest confirmation.

If the field shows a different code, empty, or says “No referrer,” your account is not bound to 31999414. If the status says “Pending” or “Inactive,” the binding may not have completed, and you should avoid trading until you understand the situation.

Even if mobile shows a binding, perform a quick cross-check on the web platform because feature rollouts can differ by device. After logging in on the official website, click your avatar and select “Rewards” or “Referral Program.” Look for a section such as “My Referral Relationship” or “Referrer Details.” Confirm that the displayed referrer code is the same as the mobile app. If one view shows 31999414 and the other does not, contact OKX support before making new trades.

Some users also check under “Fee Rate” or “Fee Schedule.” While not a direct confirmation, a reduced fee tier or a note about “Invitee Fee Discount” can support the view that the binding is active. However, the referrer code field is the authoritative indicator.

This step is optional but gives you measurable proof. Place a tiny futures order of $20 or $50, close it, and then open your trade history. Check the fee charged and then look at your rebate record or fee discount line. If the rebate appears, your 31999414 binding is functioning. If no rebate appears after a short time, verify your fee tier and contact support. Avoid using large positions as your first test; a small trade is enough to confirm the relationship without risking meaningful capital.

Remember that rebates can be paid in different ways depending on the product. Some appear instantly as fee discounts, while others are credited later to your funding account. The key is to check whether the paid fee is lower than the standard fee for your VIP level.

This is the critical branch point. If your account has no referrer, a different referrer, or an inactive status, you cannot simply edit the code after your first deposit or trade on most OKX accounts. The referral relationship is locked at the moment of successful registration and initial trading activity. Some regional support teams may not be able to change the binding once it is locked, even if you ask politely.

The cleanest solution, if you have not yet deposited or traded, is to log out and create a fresh account using the official registration entry with the code 31999414. If you have already completed KYC or deposited, check with OKX support first; some limited exceptions may exist, but you should assume that a new account with a new device, phone number, and email may be required. Do not create multiple accounts to abuse the referral program because that can trigger compliance restrictions.

Risk Warning 1: Crypto derivatives carry extreme risk. Leverage can amplify losses, and you can lose more than your initial margin. A fee rebate does not reduce market risk. Never trade more than you can afford to lose, and do not confuse saving 20% on fees with a reason to trade more frequently.

Risk Warning 2: Referral program terms are controlled by OKX. A “lifetime” rebate is defined by OKX’s terms. The platform can change, suspend, or terminate the referral program, fee tiers, or rebate rate. Always verify the current terms on the official OKX website, and be extremely careful with external links claiming guaranteed rebates. Phishing sites often imitate registration pages to steal credentials.

Risk Warning 3: Account eligibility and compliance matter. Using multiple accounts to exploit referral rewards may violate OKX’s terms and lead to account freezing. Only register with your own accurate identity information. If your account is already KYC-verified, do not attempt to manipulate the binding through unauthorized means. Not financial advice.
