Can I add a Binance referral code to an existing account?

No. Binance binds the referral relationship at the moment the account is created, and it cannot be changed afterwards by you or by support. If you already have an account without a code, the discount is not available to you on that account.

Does a Binance referral code cost me anything?

No. The exchange pays the affiliate out of the trading fees it already collects, and the referral discount reduces what you pay. Your fee with a valid code is lower than it would be without one, never higher.

Can US residents use a Binance referral code?

Not on the global platform. Binance.com does not accept US registrations. Binance.US is a separate company with its own order book and fee schedule, and codes are not transferable between the two.

The code below is one we hold. Terms last checked against Binance's published schedule on Aug 14, 2026.

Referral code

Carried by the signup link. Open the link, then check the referral field on the form shows the code before you submit.

Effective taker

We earn a commission when you register through a link on this site. It costs you nothing extra. The referral discount is applied to your fees regardless. Information only. Not investment advice.

What the Binance code actually gives you

The Binance code applies a 20% discount to your trading fees, and it is attached by the signup link rather than typed in. That matters more here than at most venues, because Binance binds the referral at the moment the account is created and neither you nor support can add one afterwards. There is no second chance on this step.

What the discount is worth depends entirely on which market you trade. On spot, 20% off 0.10% saves you two basis points a trade. On futures, 20% off a 0.05% taker rate saves one. Smaller in absolute terms, but futures is where the volume is, so it compounds far faster. It stacks with the BNB fee discount, and neither depends on reaching a VIP tier.

The thing that most often goes wrong is registering on the wrong Binance. Binance.US is a separate company with its own order book and its own fee schedule, and a code for the global platform does nothing there.

How to make sure the Binance code applies

Open the registration page through the referral link
The code has to be attached at the moment the account is created. Binance will not apply one retroactively, and support cannot attach it later, this is the single step that people get wrong.
Confirm the code appears on the form
Before submitting, check that the referral field on the registration page shows the code. If it is blank, the link did not carry it through. Usually because a browser extension stripped the parameter. Enter it manually before continuing.
Complete identity verification
Binance requires KYC before withdrawals and before most trading functions. Have a government photo ID ready. Verification usually completes within an hour but can take longer during high-volume periods.
Enable two-factor authentication before depositing
Set up an authenticator app rather than SMS. SIM-swap attacks are the most common way retail exchange accounts are drained, and SMS-based 2FA does not protect against them.
