08 · OKX referral sign-up FAQ

OKX referral sign-up
FAQ.

What does the OKX referral code do?

Enter OK66688 when you sign up and OKX permanently discounts your spot and futures trading fees by 20%. It is not cashback from a person; the platform simply charges less.

How do I open an OKX account?

Open the OKX sign-up page, register with email or phone, set a password, enter the verification code, check the referral code, verify your identity and set up 2FA.

Is joining OKX free?

Yes. Signing up and verifying are free; you only pay fees when you trade.

Can I add the referral code after signing up?

No. Referral codes can only be entered at sign-up and existing referral links can't be changed.

Are private cashback groups safe?

The risk is that money passes through a private person: you pay full fees and wait for them to send part back, and they can vanish. Never give anyone your login.

Which trades get the 20% discount?

Spot and futures trading fees. Earn products, dual investment and loans don't charge trading fees, so there is nothing to discount.

Can I get welcome rewards and the discount?

Yes. Using a referral code does not affect new-user tasks or mystery boxes.

Where do I find my UID?

Open the OKX app and tap your avatar in the top-left corner. The number under your nickname is your UID.

Is this the official OKX website?

No. This is an independent website with sign-up guides. We don't sign up or verify for you, give signals or handle money. We may earn a commission if you sign up through our links, at no extra cost to you.
