1. Can You Add the Code After Registering?

Straight answer: Binance referral codes can only be entered at the moment of registration and usually cannot be added later. Like most exchanges, the referral relationship is bound when the account is created and cannot be backdated. So we strongly recommend entering BTC9149 in one step via https://www.bsmkweb.cc/join?ref=BTC9149 to avoid missing the 40% discount.

2. Binance Sign-Up Guide (Step by Step)

Open sign-up: Click the invite link https://www.bsmkweb.cc/join?ref=BTC9149; the code is auto-filled.
Enter account info: Provide email or phone and set a password.
Bind the code: Confirm the "Referral Code / Inviter" field shows BTC9149.
Finish registration: Pass the verification code and submit.
Verify (KYC): After login, upload ID to raise limits and security.
Deposit & trade: Once KYC is done, fund and start buying.

3. Where Do You Enter the Code?

The referral code is below the account fields on the registration form, labeled "Referral Code / Inviter (Optional)." Although marked "optional," once registration is complete it can't be added. If you enter through https://www.bsmkweb.cc/join?ref=BTC9149, the system auto-fills BTC9149 — easiest and safest.

6. Frequently Asked Questions

Q1: I skipped it at sign-up — can I add it in settings later?

A: No. Binance binds the code only at registration; after the account exists it can't be added. You'd need a new account to bind it.

Q2: Does the 20% BNB discount need a referral code?

A: BNB discount is a general Binance feature, not tied to a code. But the 20% referral rebate requires registering via BTC9149; stack both for 40%.

Q3: How do I make sure I didn't miss the code?

A: Enter through https://www.bsmkweb.cc/join?ref=BTC9149 so BTC9149 is auto-filled; after sign-up you can confirm the binding under "Referral / Inviter."
