📌 September 2026 OKX Referral Code Quick Info

1. What is the OKX Referral Code for September 2026?

The OKX referral code used in this article is BTC9149. If you dont have an OKX account yet, you can start directly from the referral link:

OKX Referral Link: https://okx.com/join/BTC9149
OKX Referral Code: BTC9149

By registering with BTC9149, you can enjoy up to 20% fee rebate under that referral relationship. The referral relationship can only be bound during registration and cannot be added afterward.

If you already plan to use BTC9149, it is recommended to enter directly through the referral link, then confirm the referral code field on the registration page. This is more stable than creating a blank account first and handling the referral relationship later.

2. Where to Enter BTC9149?

The OKX referral code is entered on the registration page. OKX still retains the "Referral Code (Optional)" field — this is the step beginners miss most easily.

App:
OKX App → Register → Select Country/Region → Enter Email → Referral Code (Optional) → Enter BTC9149 → Complete Registration

Web:
OKX Official Website → Register → Select Country/Region of Residence → Enter Email → Referral Code (Optional) → Enter BTC9149 → Complete Registration

Complete Process:

1. Open the OKX referral registration page https://okx.com/join/BTC9149
2. Confirm your actual country/region of residence
3. Enter your own Email
4. Find the "Referral Code (Optional)" field
5. Enter BTC9149
6. Double-check that the referral code has no input errors
7. Complete Email verification
8. Add and verify your own phone number
9. Create the OKX account
10. Then complete identity verification (KYC)

3. What is the 20% Fee Rebate of BTC9149?

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

Different OKX referral programs, promotions, and jurisdictions may vary, so the final rebate rate should be based on the actual Rebate rate shown in your account. OKX does currently offer a program with up to 20% invitee trading fee discount — for example, some official partner pages explicitly state that invitees can enjoy a 20% eligible trading fee discount.

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

4. Can the OKX Referral Code Be Changed After Binding?

A referral relationship for a standard OKX account should be completed during registration; once the account is created, the referral code usually cannot be added or changed. OKXs official referral rules clearly state that the referral relationship is only bound during registration, and once registration or identity verification is completed, that relationship cannot be modified.

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

5. How to Check Whether BTC9149 Has Been Bound Successfully?

OKX currently provides an in-account referral relationship lookup. The official instructions state that if your account has a queryable referral/node relationship, you can check it in your profile under "Invite Rewards" or "Invite Perks."

Lookup path:
OKX App → Grid Menu → Account Settings → Profile → Invite Rewards / Invite Perks

If the page shows Invite Perks, you can usually further see the referral code currently bound to your account, the related referral benefits, and some accounts can see the Rebate rate and referral relationship status. If the displayed referral code is BTC9149, it means the referral relationship has been correctly established.

6. Why Dont I See the 20% After Binding BTC9149?

Successfully binding the referral code and actually seeing the rebate are two separate steps that need to be confirmed separately. Common reasons include:

• The region youre in applies different referral rules;
• Your account is enrolled in a different promotion program;
• The rebate rate has not yet been displayed on the current page;
• The traded product is not covered (on-chain Gas, withdrawal fees, etc. are usually not covered by the 20% rebate);
• The referral relationship was not successfully established;
• Your account was already bound to another referral code;
• Sub-accounts or special accounts dont follow the same referral rules.

The most direct way is to go to your accounts Invite Perks / Invite Rewards page and check the actual Rebate rate. If its not shown in the interface, you can provide your UID, registration time, and referral code BTC9149 directly to official support for inquiry.

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

No. The referral code is mainly used to establish a referral relationship, while new-user rewards usually also require completing KYC, a deposit, or specific tasks.

OKXs current referral activity may offer fixed rewards, lucky draws, or different reward combinations, and the tasks different users see may not be identical.

So even after binding BTC9149, you can still go to the OKX Activity Center to see which new-user tasks you can currently join. The two are parallel, not mutually exclusive.

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

Yes. OKXs official registration guide states that identity verification is required after registration; accounts that havent completed real-name verification cannot normally use buying/selling, deposits/withdrawals, internal transfers, lending, or fund transfers.

KYC generally requires:

• Your real name;
• Date of birth;
• Actual country/region of residence;
• A valid government-issued identity document;
• A clear, complete photo of the document;
• Facial recognition as prompted by the system.

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

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

If the account has already been created, the referral relationship generally cannot be added directly afterward. OKXs official referral rules currently state clearly that the referral 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, and confirm whether a referral relationship already exists;
2. If you cant confirm, contact OKX official support, provide your UID, and ask about the currently bound referral status.
