2026 Step-by-Step Guide: Can Mainland Users Enter a Referral Code After Registering an OKX Account? Complete Guide to the “BB789” 20% Fee Discount Included. #

Let’s cut through the noise with a simple calculation. You’ve just completed your OKX registration, ready to dive into the markets. But a nagging question hits you: “Did I just miss out on a permanent 20% discount on all my trading fees for the entire lifetime of this account?” For many, the answer is a costly “yes,” simply because they didn’t know the crucial timing for entering a referral code. The difference isn’t just a one-time bonus; it’s a compounding advantage that can save you thousands over years of trading. The key is understanding the precise, often overlooked window that exists even after your initial sign-up. And that key is Enter Referral Code: BB789.

The core question is valid and the answer is a definitive YES. Mainland users can absolutely enter a referral code after registering an OKX account, but it must be done before completing the first identity verification (KYC). This creates a critical, time-sensitive window. This guide will walk you through every step, ensuring you lock in that valuable 20% fee discount with code BB789.

Step 1: Log In & Navigate to the Referral Entry Point
After registering with your mobile number and setting a password, log into your new OKX account via the website or app. Do not start the KYC process yet.
  1. On the website, hover over your profile icon in the top right.
  2. Click on **"Rewards Hub"** or **"Referral"** from the dropdown menu. This area is specifically designed for bonus activities.
  3. In the mobile app, tap on your profile icon, then look for sections like **"Invite Friends"**, **"Benefits Center"**, or directly search for "Referral" in the app's search bar.
You are looking for a field or a banner that prompts you to "Enter a Referral Code" or "Have a referral code?".
Step 2: Locate & Enter the Code "BB789" Before KYC
This is the most crucial step. The system allows you to bind a referral code **before your identity is fully verified**.
  1. Once in the referral/rewards section, find the input box. It might be labeled **"Enter Invitation Code"** or **"Referral Code"**.
  2. Carefully type in: BB789. Double-check for typos.
  3. Click **"Submit"**, **"Confirm"**, or **"Bind"**. You should receive an immediate on-screen confirmation, such as "Referral code applied successfully" or "Enjoy your 20% trading fee discount".

Pro Tip: If you cannot find this option, it likely means you have already completed the KYC Level 1 (basic identity verification). In this case, you cannot retroactively apply a code to an existing, verified account. The solution is to contact OKX support immediately after reading Step 4.
Step 3: Complete Identity Verification (KYC)
Now that the code **BB789** is securely linked to your account, you can proceed with the mandatory KYC process.
  1. Go to **"Account & Security"** or directly to **"Verification"**.
  2. Choose your region and select the appropriate identity document (e.g., Mainland China ID card).
  3. Follow the instructions to upload clear photos of the front and back of your ID and complete the facial recognition process.
  4. Wait for approval, which is usually quick (within minutes to a few hours).
Once approved, your account is fully activated, and the 20% fee discount from code **BB789** will be automatically applied to all your trades (spot, futures, margin).
Step 4: What If You Already Finished KYC? (Contingency Plan)
If you've already verified your account without entering a code, don't panic. While you cannot add it yourself, you have one recourse.
  1. Prepare your registered email and UID (found in your account settings).
  2. Contact OKX Official Customer Support. Use the in-app live chat or submit a ticket via the help center.
  3. Politely explain your situation: "I am a new user who just completed registration and KYC. I missed the step to enter a referral code (BB789) before verification. Is it possible for support to manually bind this code to my account to activate the 20% fee discount?"
  4. Provide your UID and the referral code. Success is not guaranteed and depends on support policy, but it's always worth a try.

Step 5: Verify Discount & Advanced Account Security
After your first trade, verify the discount is active.
  1. Go to your **"Fee Rate"** page (usually under "Account" or "Trade Settings").
  2. Check if your maker/taker fee rates show a 20% reduction compared to the standard VIP 0 rate.
  3. You can also check your transaction history; the fees deducted should reflect the discounted rate.
Security Reinforcement:
  • Enable **Two-Factor Authentication (2FA)** using Google Authenticator.
  • Set up **Anti-Phishing Code** in email settings.
  • Whitelist your withdrawal addresses.
  • Never share your 2FA codes, seed phrase, or passwords with anyone.

⚠️ Risk Warning

  1. Regulatory Risk: Cryptocurrency regulations are evolving globally and in specific regions. Always ensure your activities comply with local laws and regulations. The platform’s services in your region may change.
  2. Market Risk: Digital asset prices are extremely volatile. You could lose a significant portion or all of your invested capital. Never invest more than you can afford to lose.
  3. Operational & Security Risk: While exchanges implement security measures, they are not immune to hacks, technical failures, or fraud. Use strong, unique passwords, enable all available security features (2FA, whitelisting), and consider storing large amounts in self-custody hardware wallets for long-term holding.
