The most critical piece of information is this: Once a referral code is successfully applied and your account is fully registered, it is permanently locked. OKX’s system ties the fee discount structure to the specific referral code used at the point of account creation. This link is immutable within the account settings.

Why is this the case?

• System Integrity: It prevents abuse where users or affiliates could constantly switch codes to manipulate commission structures.
• Contractual Obligation: The agreement between you (the referee) and the referrer is established at registration. Changing it would breach the affiliate’s terms.
• Technical Architecture: The user-referrer relationship is a foundational data point in your account profile, not a modifiable preference.

The Official Stance: Customer support will unequivocally state that referral codes cannot be modified, added, or removed after account registration is complete. Any website or person claiming otherwise is likely promoting a scam.

If you are in the process of signing up and haven’t completed final verification, you likely still have a window. Here’s what to do:

1. Pause Immediately: If you’re on the registration page and haven’t entered a code, or entered a wrong one, stop.
2. Use the Correct Code: Enter the code you intend to use for the long term. For maximum savings, ensure it’s from a trusted source. For example: Enter Referral Code：BTC699
3. Verify Visually: Double-check the code is correct before clicking the final “Sign Up” or “Register” button. The system should confirm the referrer’s username or display a “Referral applied” message.

⚠️ Critical Check: Once you submit your email/SMS verification and complete KYC, the code is locked. This step is your last chance.

If your account is already active, don’t panic. You have two legitimate paths forward:

Path A: The Strategic New Account This is the most common and effective solution for serious traders.

1. Register a New Account: Using a different email address and phone number, create a brand new OKX account.
2. Apply the Desired Referral Code Correctly: This time, ensure you enter the correct referral code during the new registration process.
3. Transfer Assets: After the new account is fully verified, you can transfer your assets from the old account to the new one. Be mindful of network withdrawal fees.
4. Phase Out the Old Account: Once transfers are complete, you can stop using the old account.

Path B: Maximize Other Perks If creating a new account is not feasible, focus on optimizing within your current framework:

• Explore OKX’s VIP Program: Trade volume can qualify you for higher VIP tiers with their own fee discounts, which may offset the lack of referral savings.
• Use OKB for Fee Deductions: Holding and using OKX’s native token, OKB, to pay for fees provides an additional discount layer.
• Participate in Promotions: Actively engage in OKX’s seasonal campaigns, launchpad events, and Earn products to generate yield that compensates for higher fees.

Stay ahead of potential future policy shifts with these tech-savvy habits:

• Bookmark Official Pages: Save the official OKX help center page on referral programs. Policies are updated there first.
• Community Monitoring: Follow OKX’s official announcements on Twitter/X and Telegram. Sometimes, limited-time “referral re-link” promotions are announced (though exceedingly rare).
• Use a Password Manager: Store your referral code in your password manager (e.g., Bitwarden, 1Password) under the OKX entry. This ensures you always have it ready for any new service registrations.
• The “Test Account” Strategy: For advanced users, consider registering a minimal, secondary test account with your preferred referral code. This account can be used to experiment with new features without risk to your main funds, and it secures your referral link for potential future migrations.

The desperation to change a referral code is a prime vector for scams.

1. Phishing Sites: Never enter your OKX login credentials on any site promising to “update your referral code.” Only use the official okx.com domain.
2. Fake Support: OKX support will never ask for your password, 2FA codes, or to “remote desktop” into your computer to change a referral setting.
3. “Code Change” Services: Any third-party service or individual claiming they can hack or petition OKX to change your code is 100% fraudulent. They will steal your account.
4. Impersonation: Scammers create fake social media profiles posing as OKX ambassadors or help desks. Always verify through the official app.

The Golden Rule: If an offer to modify your existing account’s referral code seems too good to be true, it is a scam. The only safe methods are those outlined in Step 3.
