3. What Is the 20% Trading Fee Rebate for BTC9149?

BTC9149 corresponds to the trading fee discount in the referral relationship. This article explains it based on an up to 20% trading fee rebate / discount setting. Simply put, after a new user correctly binds the invitation code during registration, eligible trading fees can enjoy a corresponding rebate or fee discount according to the referral plan.

OKX referral plans, campaigns, and jurisdictions may differ, so the final rate should be based on the Rebate rate actually shown in your account. OKX officially does provide an invitee trading fee discount plan of up to 20%.

Therefore, if you register through https://okx.com/join/BTC9149, it is recommended to enter the "Invite rewards" page after completing your account to confirm whether BTC9149 and the actual rebate rate are displayed correctly.

---

4. Can the OKX Invitation Code Be Modified After Binding?

For a normal OKX account, the referral relationship should be completed at registration, and after the account is created it usually cannot be added or changed. OKX official invitation rules clearly state that the referral relationship can only be bound at registration, and once registration or identity verification is completed, the referral relationship cannot be modified.

So if you plan to use BTC9149, do not skip the invitation code field and complete registration first.

⚠️ It is best to handle the invitation code once at registration
The OKX invitation code is not a regular coupon; after the account is created, you should not assume it can still be filled in, replaced, or changed at any time.

---

5. How Do You Check Whether BTC9149 Is Successfully Bound?

OKX currently provides an invitation relationship query entry within the account. Official instructions state that if the account has a queryable referral / node relationship, you can view it from "Invite rewards" or Invite perks in your profile.

Query path:

OKX App → Grid/menu → Account settings → Profile → Invite rewards / Invite perks

If the page shows Invite perks, you can generally further see the invitation code currently bound to the account, related referral benefits, and for some accounts the Rebate rate / rebate ratio and referral relationship status. If the displayed invitation code is BTC9149, it means the referral relationship has been correctly established.

💡 If you cannot find Invite perks, do not immediately assume it is not bound.
Interfaces may differ by region and referral plan, so you can contact OKX official customer support to confirm.

---

6. Why Do You Not See 20% After Binding BTC9149?

Successful invitation code binding and actual rebate display are two steps that need to be confirmed separately. Common reasons include:

• Different referral rules apply in your current region;
• The account is participating in another campaign plan;
• The rebate rate is not yet displayed on the current page;
• The trading product is not covered by the discount (on-chain Gas, withdrawal fees, etc. are usually not covered by the 20% rebate);
• The referral relationship was not successfully established;
• The account was already bound to another invitation code;
• Sub-accounts or special accounts are not eligible for the same referral rules.

The most direct way is to enter the Invite perks / Invite rewards page of your account and check the actual Rebate rate. If the account interface does not show it, you can provide your UID, registration time, and invitation code BTC9149 directly to official customer support for inquiry.

⚠️ Do not judge whether the trading fee rebate is effective only by "whether you received a one-time reward."
New user campaign rewards, invitation tasks, and trading fee rebates are not the same mechanism.

---

7. Are the OKX Invitation Code and New User Rewards the Same Thing?

No. The invitation code is mainly used to establish a referral relationship, while new user rewards usually also require completing KYC, depositing funds, or specified tasks.

Current OKX invitation campaigns may provide fixed rewards, lucky draws, or different reward combinations, and the tasks seen by different users may not be exactly the same.

Item	Function
BTC9149	Establishes the referral relationship and corresponding trading fee discount
New user rewards	Claimed after completing KYC, deposit, or trading tasks according to the campaign
Campaign Bonus	Issued according to the current campaign rules

So after binding BTC9149, you can still go to the OKX campaign center to see which new user tasks you can currently participate in. The two are parallel, not mutually exclusive.

---

8. Do You Still Need to Complete KYC After Registering on OKX?

Yes. OKX official registration guidelines state that identity verification is required after registration; accounts that have not completed real-name verification cannot normally use buy/sell crypto, deposit/withdrawal, internal transfer, lending, and fund transfer functions.

KYC generally requires:

• Your real name;
• Date of birth;
• Real country/region of residence;
• Valid government-issued ID;
• Clear and complete ID photos;
• Complete face recognition as prompted by the system.

After completing KYC, set up security features such as Authenticator, Passkey, mobile and Email verification, and then proceed with USDT deposit or your first trade.

---

9. What If You Already Registered but Forgot to Enter BTC9149?

If the account has already been created, the referral relationship generally cannot be filled in directly afterward. OKX official invitation rules currently clearly state that the invitation code must be entered when registering the account, and cannot be added or changed after the account is created.

You can do two things first:

1. Go to Account settings → Profile → Invite rewards / Invite perks to confirm whether a referral relationship already exists;
2. If you cannot confirm, contact OKX official customer support, provide your UID, and ask about the current referral binding status.

⚠️ Do not casually create multiple accounts just to re-enter the invitation code.
Account eligibility, KYC, campaigns, and multi-account rules may all be subject to platform risk control restrictions.
