Where to Enter OKX Referral Code OK800? Enter It at Signup for 20% Rebate

You searched "where to enter the OKX referral code" — the answer is one line: you enter it at the signup step, not afterward inside your account. When you create an account with your email or phone number, the page has an (optional) referral code field — just enter OK800.

And this step is a one-shot deal — OKX's official rules are clear that the referral code can only be entered at signup; once the account is created it can't be added or changed.^[1] So what matters isn't "where to enter" but "enter it correctly while signing up".

Quick overview

• The code is only entered on the signup page, at the email/phone step, not after registering.
• It's best to use a referral link that already carries OK800, so the code is filled in automatically and you avoid typos.
• Enter it correctly and you get the rebate shown on the page; if the page shows a 20% fee rebate, you get that rebate under the page's rules.
• Official rule: the referral code can't be added or changed after account creation, so don't think "I'll register first and add it later".
• You can register without a code, but you usually won't get the referral rebate.

Your situation	What to do
Not registered yet	Use a referral link carrying OK800, and enter OK800 at the account-creation step
Registered but forgot OK800	The official rule says the code can't be added or changed after creation; in the ordinary case it can't be filled in later
Entered the wrong code	It's bound at signup and usually can't be changed; double-check before submitting
Want to confirm it's bound	Check the signup / campaign / account invitation pages for OK800 and the rebate ratio
Not entering a code	You can still register, but usually won't get the referral rebate

If all goes smoothly it takes under 3 minutes. The two easiest ways to stumble: assuming you can fill it in after registration is complete, and using a referral link without confirming the code actually carried over.

Which signup step is the OKX referral code entered at?

The OKX signup flow is roughly: open the official channel → choose your region → enter email/phone → receive the verification code and set a password → KYC → security settings.

The referral code appears at the "enter email or phone to create the account" step. There, besides entering your email or phone, the page usually has an (optional) referral code field. Enter OK800, then continue with the verification code and password.

It is not in these places:

• Not in "profile" or "settings" after registration — there's no field there;
• Not during KYC;
• Not when depositing.

It's only at the account-creation step. Miss that step and, under the official rules, the code can't be added after the account is created.

Why do I recommend using a referral link instead?

Typing OK800 by hand works, but a more reliable way is to open a referral link that already carries OK800.

The reason is simple: when a referral link is opened, the code is usually filled in or recognized automatically, so you just confirm the code shown is OK800 — no risk of a typo. One wrong character and the rebate binds to someone else's code, and under the rules you can't change it.

Open the OK800 signup entry and enjoy the 20% fee rebate

Then go through the normal signup flow. Before clicking, confirm you're on the official OKX domain, and check the page shows OK800.

Will signing up with OK800 give a 20% rebate?

If the page shows a 20% fee rebate when you register with OK800, then the account gets that rebate under the rules shown on the page. But two things need to be clear:

First, the 20% rebates the fee, not the trade amount. Say a 10,000 USDT trade generates a 10 USDT fee; the rebate is 10 × 20% = 2 USDT, not 20% of 10,000.^[2]

Second, what the page shows is what counts. The rebate ratio, covered products and duration may change with the rules; whatever the page shows at signup is what you get.

Can you still register without entering a code?

Yes. The referral code is optional — you can register and use the account normally without it.^[3]

But without a code you usually don't get the fee rebate that comes with a referral link. So if you're going to register anyway, entering OK800 is better than leaving it blank.

Forgot to enter it at signup — can you still add it later?

This is the easiest pitfall to hit, and the most important thing this article needs to make clear.

Under OKX's current official referral rules, the code must be entered before the account is created; once registration is complete, the referral relationship usually can't be added or changed.

So if you've already finished signing up and only then realized you forgot OK800, there is currently no ordinary "add a referral code" entry point.

Two things to do here:

• If you're not sure whether a referral relationship is already bound, contact OKX official support to verify your account status;
• Don't delete the account, re-register, or use someone else's identity to open a new account just to change the code.

OKX's latest referral program rules specifically warn that deleting an account and re-registering will not restore the original referral eligibility or new-user reward eligibility, and multi-account operations may violate campaign rules.^[4]

So the safest approach remains: confirm the code is correct the first time you create the account.

What if you entered the wrong code?

Same official rule: the referral relationship is bound at signup and can't be changed afterward.

So entering someone else's code binds you to that code, and in the ordinary case it can't be changed. This is why I keep emphasizing using a referral link and double-checking it's OK800 before submitting.

If you haven't submitted yet, go back and re-check. If you've already finished signing up and only then noticed the mistake, whether it can be changed depends on the official support reply — don't casually close and reopen the account.

How to confirm OK800 is actually bound?

After signing up, don't just look for "rebate records" — before any fee is generated, the record may naturally be empty.

First check the signup page, campaign page, or the account's invitation/rebate page to confirm it shows OK800, the fee rebate ratio or the corresponding campaign benefit. The entry may differ by region, account version and campaign page, so go by what your own account actually shows.

If the page doesn't show a referral relationship or rebate ratio, contact OKX official support to verify — don't close and reopen the account on your own based on a third-party tutorial.

FAQ

At which signup step do you enter the OKX referral code?

At the "enter email or phone to create the account" step, in the page's (optional) referral code field.

Where should OK800 be entered?

In the referral code field when creating the account on the signup page. Or use a referral link carrying OK800 so the code is filled in automatically.

If I use a referral link, do I still enter OK800 myself?

Usually not — opening the link fills in the code automatically; just confirm it.

Does OK800 always rebate 20%?

If the signup page shows a 20% fee rebate, the account gets that rebate under the page's rules; the ratio is whatever the page actually shows, and it rebates the fee, not the trade amount.

I forgot the code at signup — can I still add it?

The official rule is that the code can't be added or changed after account creation; in the ordinary case it can't be filled in later. Whether it can be remedied depends on official support and the page.

Can I change it if I entered it wrong?

Once bound at signup it usually can't be changed. So always double-check before submitting.

Can I use OKX normally without a referral code?

Yes, the code is optional; without it you just usually don't get the referral rebate.

My recommendation

One line: before registering for OKX, have the OK800 referral link ready, register all the way through in one go, and confirm you entered OK800 at the account-creation step.

Because OKX's rule is "no adding or changing after signup", which is stricter than Binance's. Binance old users still have re-binding and recall flows, but OKX's ordinary referral code has no such after-the-fact entry. So put the effort into entering it correctly that one time at signup, rather than trying to fix it afterward.
