TL;DR: Not all Binance referral codes are equal. Some give 20% fee discounts, others give 10% or nothing at all. Before you sign up, check the code first — because you can't change it after registration
Most people sign up to Binance using a referral code they found on Reddit, YouTube, or a random blog post. They assume the code is legitimate. They assume it gives a discount. They find out later it didn't — after it's too late to change anything.
This guide explains what a Binance referral code actually does, why codes vary, and how to verify one before you commit to it.
What Does a Binance Referral Code Actually Do?
When you register on Binance with a referral code, two things can happen:
1. You get a fee discount (rebate) The code owner shares part of their affiliate commission back to you as a trading fee rebate. The maximum possible discount is 20% on spot trading fees.
2. You get a new user welcome bonus Binance runs welcome campaigns that give new users up to $19,800 in task-based rewards — deposits, trades, and identity verification each unlock different bonus tiers.
Both benefits are tied to the code you use at registration. Once your account is created, the code is locked in permanently. Binance does not allow you to add or change a referral code after signup.
Why Do Some Codes Give 20% and Others Give Nothing?
The rebate rate depends on the affiliate's tier and how they configure their commission split.
Binance affiliates can share up to 100% of their earned commission with the people they refer. A code offering 20% means the affiliate is passing their full commission back to you. A code offering 0% means they are keeping everything.
The problem is that most websites promoting Binance referral codes don't show you the actual rebate rate. They just show you the code and tell you to use it.
How to Verify a Binance Referral Code
There are two ways to check a code before signing up.
Option 1: Check it on Binance directly
On the Binance registration page, enter the referral code in the "Referral ID" field. Binance will show you the discount percentage linked to that code before you complete registration.
Option 2: Use a dedicated code checker
This is what Binance Code Check was built for. Enter any code and see the verified rebate rate, fee discount percentage, and new user bonus details — all in one place, before you sign up anywhere.
What to Look For in a Good Code
When evaluating a Binance referral code, check three things:
Rebate rate — Is it 20%? That's the maximum. Anything lower means you're leaving money on the table on every trade you make, forever.
New user bonus — Does the code unlock the full $19,800 welcome campaign, or a reduced version? Some codes are linked to campaigns with lower bonus caps.
Verification date — Codes and campaigns change. A code that was valid last month might link to a different bonus today. Always check the most recent verification date.

Frequently Asked Questions
Can I use a referral code after I've already registered? No. Binance only accepts referral codes at the time of registration. Once your account exists, the code cannot be added or changed.
Does every Binance referral code give a 20% discount? No. The discount depends on how the affiliate configures their commission split. Some codes give 20%, some give 10%, and some give 0%. Always verify before signing up.
What happens if I sign up without any referral code? You won't get any fee discount, and you may miss out on the new user welcome bonus. There's no reason to sign up without a verified code.
How long does the welcome bonus last? The new user bonus tasks must typically be completed within 14 to 30 days of registration. The tasks include depositing funds, completing KYC, and making your first trade.
Is Binance Code Check affiliated with Binance? No. Binance Code Check is an independent tool built to help users verify referral codes before signing up. We are not affiliated with Binance.
