Can you add an OKX referral code after registration?

Not through the referral code field — OKX only reads that at sign-up. But OKX has an official referral change request that switches the referral on an existing account without closing it, as long as the account meets OKX's account-age and trading-volume conditions. loweef's OKX referral change guide shows the current conditions table and the request link.

Why the code field doesn't work after sign-up

OKX sets the referral attribution once, when the account is created. Typing a code later somewhere in the app doesn't update it — that is the most common reason a code seems not to work.

The official route: OKX's referral change request

OKX accepts a request to change the referral on an existing account. You keep the account, its balance and its verification. In short:

Open OKX's referral change link and log in — it takes you to the change screen.
Enter the new referral code (it may be pre-filled).
Write a short reason in English in the "Reason for joining" field.

The OKX referral change guide has the link, the code and a reason template you can copy.

Who qualifies

Eligibility depends on two things: how old the account is and how much it has traded. The newest accounts have the widest room; older accounts must stay under a volume cap that rises with account age. The exact bands are OKX's and can change, so the guide renders them from the latest confirmed table rather than repeating them here.

If your volume is above the final cap, the guide explains the fallback — closing the account, waiting OKX's cooling period and signing up again through the link — and what to check before doing it. Below that cap, account age only grows, so waiting for a later band can be enough.

One account, not two

The change request moves your existing account to a new referral; it doesn't call for a second account. Keeping a second account of your own to refer yourself is a self-referral scheme — it isn't eligible for payback under loweef's terms.

What the change does

Once the referral is switched to loweef's OKX code, 50% of each trading fee you pay comes back to you, accruing daily in USDT:

Exchange	Total rate	Welcome boost	Effective taker
AlphaX	65%	—	0.0175%
BingX	60%	70%	0.0200%
OKX	50%	60%	0.0250%
MEXC	55%	65%	0.0180%

Figures are estimates based on published rates; actual results vary with VIP tier and maker/taker mix, and rates can change prospectively.

Frequently asked questions

Do I have to close my OKX account to add a referral code?

Usually not. OKX's referral change request switches the referral on an existing account without closing it, if the account meets the account-age and volume conditions. Closing and re-registering is only the fallback when your volume is above the final cap.

What are the OKX referral change conditions?

They combine account age and cumulative trading volume. The current bands are in the OKX referral change guide, which is generated from the latest confirmed table.

Can I just type the code in the OKX app after signing up?

No. The referral code field is only read at account creation. On an existing account, the referral change request is the route.
