Do You Need a Referral Code to Sign Up?

Opening a Binance account does not strictly require a referral code — you can register without one. But if you want the 20% rebate and the up to 40% combined fee saving you get after enabling BNB fee deduction, you must bind code BTC9149 during registration. The code only affects the fee rebate, not your basic account functions.

Can You Add the Code Later?

No. The referral code can only be entered once at sign-up, and the system generally does not allow adding it after the account is opened. If you skip BTC9149 at registration, you lose the 20% rebate; even if you later enable BNB fee deduction on your own, you only get that part and cannot reach the up-to-40% saving. BNB deduction itself can be turned on anytime in "Account Settings," but the "code + rebate" step must be done at sign-up.

Why Enter BTC9149 at Sign-Up?

Binding BTC9149 gives you a 20% rebate; turn on BNB fee deduction and the two combine for up to 40% in fee savings, which clearly lowers your real trading costs over time. Since the code cannot be added later, entering it early ensures the benefit applies from day one.

How to Enter the Code Correctly

Step 1: Enter the code. Use the referral link below to reach the pre-filled sign-up page, or type BTC9149 manually in the App:

Step 2: Verify identity. Enter your email or phone number and complete the code check.

Step 3: Secure the account. Set a login password and enable two-factor authentication (2FA).

Tip: After registration, open "Account Settings → Fee" to enable BNB fee deduction; combined with the 20% rebate, you get up to 40% in fee savings.

Things to Note

• The referral code is entered only once at sign-up; it cannot be added or changed after the account is opened.
• BNB fee deduction can be enabled anytime in settings, and stacks with the 20% rebate for up to 40% in fee savings.
• Register through the official App or referral link, and enable 2FA and a withdrawal whitelist to protect your assets.
