The easiest thing for a first-time Binance user to miss is the referral code field. It is not decoration. It creates the referral relationship for a new account. This guide uses BNOFFICIAL: bind the referral code first, then complete KYC, security settings, and finally turn on BNB fee deduction. That is the more reliable order for a long-term Binance user.

Do not read the fee story as one number. Split it:

• BNOFFICIAL referral code: may provide a referral fee benefit. A common marketing figure is up to 20% on spot, but the actual rate depends on your account, region and Binance's campaign.
• BNB fee deduction: Binance's common official discount is up to 25% on Spot/Margin and 10% on Futures, and requires enough BNB plus the feature enabled.
• "Up to ~40%": a combined way of speaking — referral benefit plus BNB discount — not a guaranteed fixed 40% on every trade.

Why bind BNOFFICIAL first, then enable BNB deduction?

1BNOFFICIAL is the referral relationship

Entered or pre-filled during sign-up, it marks which referral source the new account came from. Referral benefits usually attach to this relationship.

2BNB Fee Deduction is a payment method

After registration, enable "Use BNB to Pay Fees" and hold enough BNB. Then Binance can pay eligible trading fees in BNB and apply the discount.

Bind BNOFFICIAL → KYC → security settings → keep a little BNB → enable BNB fee deduction → test with a small trade

Full beginner flow

1. Sign up from the official link

Open https://www.binance.com/join?ref=BNOFFICIAL and confirm the Referral Code / Referral ID field shows BNOFFICIAL.

2. Use an email you actually check

Gmail or Outlook is fine. Login verification, withdrawal alerts, KYC notices, new-device logins and risk-control emails all arrive there. Do not use a throwaway email.

3. Download the official app

Official download guide: https://www.binance.com/en/download

• iPhone: App Store
• Android: Google Play or Binance official Android APK
• Do not install from Telegram, LINE groups, private drives or unknown short links

4. Complete KYC

KYC = Know Your Customer. Prepare:

• Full legal name
• Date of birth
• Country / region
• Government-issued ID
• Face verification
• If requested: proof of address

Common KYC failures:

• Name does not match the ID
• Glare, blur, missing corners on the document
• Expired ID
• Dark environment
• Hat or mask during face check

5. Security first, then deposit

• 🔐 Google Authenticator: save the recovery key offline
• 🔑 Passkey: enable if your device supports Face ID / Touch ID / Android biometrics
• 📧 Anti-Phishing Code: set a string only you know, e.g. BN-SAFE-2026
• 🛡️ Withdrawal Address Whitelist: restrict withdrawals to approved addresses

6. Keep a little BNB and enable deduction

App path: Profile → Settings → BNB Discount → enable Use BNB to pay fees. On web, toggle BNB Discount in Fee Level / Fees & Transactions Overview.

7. Small USDT deposit

When transferring USDT from another exchange or wallet, sender network must match Binance receive network:

First deposit: send 10–20 USDT first, confirm arrival and correct network, then send the rest.

8. First spot trade

Trade → Spot → BTC/USDT or ETH/USDT. Beginners can start with 50–100 USDT market order. After execution, check Trade History / Order History for Fee. If the fee is deducted in BNB, BNB Fee Deduction is active.

Common misconceptions about BNOFFICIAL and BNB deduction

Misconception 1: 40% is a guaranteed fixed discount

No. Referral benefit rate, BNB discount rate, eligible products (spot/futures/margin), VIP level, region and campaigns all affect the final fee.

Misconception 2: Enabling BNB deduction guarantees a discount

Your account needs enough BNB, and the trade must be in an eligible product and fee structure for the discount to apply.

Misconception 3: Lower fees = lower trading risk

Fees only affect cost. They do not affect price volatility. High leverage, high frequency and FOMO trading risks do not disappear just because fees are lower.

Misconception 4: Adding a referral code after registration is always easy

Binance referral relationships are usually bound at account creation. Whether an already-registered account can add a code depends on whether Binance provides a self-service option. If another referrer is already bound, it usually cannot be changed.

FAQ

What Binance referral code should I use?

This guide uses BNOFFICIAL. Link: https://www.binance.com/join?ref=BNOFFICIAL

How much fee discount does BNOFFICIAL give?

A common marketing figure is up to 20% on spot referral fee discount, but the actual rate depends on your account display. Not all products have the same rate.

Where does the "up to ~40%" come from?

Markets often combine "referral code benefit + BNB deduction" as a total. Binance official BNB discount is commonly up to 25% on Spot/Margin and 10% on Futures. Added together, people call it "up to ~40%", but it is a combined statement, not a guaranteed number.

Can I enable BNB deduction without holding BNB?

You can toggle the setting, but without enough BNB, the system cannot pay fees in BNB and the discount will not actually apply.

Is KYC mandatory on Binance?

To use full features like buy crypto, spot, P2P, deposit, withdrawal and Earn, KYC is usually required. Unverified accounts have limited functions and limits.

Can I add BNOFFICIAL after I already registered?

Do not assume it is always possible. Check Referral / Rewards / Account / Support for your current referral relationship. If another referrer is already bound, it usually cannot be changed. The safest method is to use the correct link from the start.
