Many users ask:
“Can I still enter a Binance referral code if I already signed up?”

Here’s the clear answer:

❌ If You’ve Already Signed Up and Used Binance:

You cannot add a referral code afterward. Binance does not allow codes to be applied retro actively once your account is active and has trading history.

✅ Exception: Inactive Accounts Over 180 Days

If:

• You registered without a referral code, and

• Your account has been completely inactive for 180+ days

👉 You may be eligible to re-register with a referral code like BTC2025 to claim the 20% fee discount.

Check directly with Binance support to confirm if you qualify for this.

🎯 New to Binance?

If you haven’t created an account yet:
Use referral code BTC2025 during signup to get a 20% lifetime discount on spot trading fees.

📌 Use BTC2025 Now for 20% Off Spot Fees

Don’t miss it — you only get one chance.
