Where to Enter Your OKX Referral Code? Sign-Up Fill Position + Post-Signup Fix Guide (2026)
📌 Start here
- An OKX referral code can only be entered on the signup page — find the “Referral code (optional)” field and type it in; once the account is created it can never be added or changed. That’s the official OKX rule, and the single most important sentence in this article.
- Signing up through a referral link fills the code in automatically — no manual entry needed; if you register manually you need to expand the field and type it yourself. We recommend OKCOOL.
- A wrongly entered code can’t be changed either — the only fix is to close the account and re-register, so double-check before submitting.
- After signing up, you can check the referral binding in the App under Settings / Profile to confirm the code took effect.

The short answer: an OKX referral code can only be entered at the moment of signup — afterward it can neither be added nor changed. That’s the official rule of the OKX referral program, not something support can bend as a favor. Many people skip the code field at signup, or use the wrong code, and only later ask “can I add it afterward?” — the answer is no. So here’s how to read this article: if you haven’t registered yet, read “Where do you enter the referral code?” and the 4-step signup walkthrough to get it right the first time; if you’ve already registered, jump straight to “Can I add a referral code after registration?” and “What if I entered the wrong code?” for the realistic options.
Where do you enter the OKX referral code?
The referral code goes in the “Referral code (optional)” field on the signup page. Both the website and the App have this field in the signup form, but it’s collapsed by default — many people fill in their phone and password, hit register, and never notice the field. That’s the most common way people “forget” to enter a referral code.
Here is the full 4-step OKX signup flow — the code comes in at step 3:
- Go to the signup page: click “Sign up” on the official website or in the App to reach the registration page. Going in through a referral link is recommended (explained below) — don’t rush to fill things in the moment the page loads.
- Enter your account and password: phone number or email, plus a login password. OKX supports both phone and email signup — either works.
- Expand “Referral code (optional)” and enter the code: find this field at the bottom of the signup form, expand it, and type the code — for example OKCOOL. This is your only chance; check the spelling and letter case before submitting.
- Complete signup and KYC verification: after submitting, complete OKX KYC verification as prompted. Once verified, the account is fully unlocked and rebates and new-user perks kick in.
Common pitfalls: ① the code field sits at the very bottom of the form — scroll down on mobile to see it; ② it’s labeled “optional”, so you can register without it, but skipping it means giving up the rebate; ③ it’s case-insensitive, but don’t add extra spaces — stray spaces break recognition.
Does signing up through a referral link fill in the code automatically?
Yes. Click a referral link to reach the signup page and the code fills into the “Referral code (optional)” field automatically — no manual entry needed. This is the signup method we recommend most: no typing, no typo risk.
Even with a referral link, do one manual check: after the signup page loads, expand the “Referral code (optional)” field and confirm a code is there (e.g. OKCOOL). In rare cases — browser cache, intercepted redirects, or a mid-way page refresh — the auto-fill can fail. A 3-second glance avoids the “I thought it was filled but it wasn’t” trap.
If you’re already using a referral link, there’s no need to type the code again — entering the same code twice changes nothing. For the code’s own rules and perks, see: OKX Referral Code 2026 Signup Guide.
Can you add a referral code after registration?
No — that’s the official OKX rule. The referral relationship binds to the code the moment the account is created, and it can never be changed or added afterward. There is no “add referral code” entry anywhere in the OKX App or website; account settings only let you view the referral relationship, never edit it.
Common “workaround” claims, debunked one by one:
- “Support can add it for you”: OKX support generally won’t add or change referral relationships for existing accounts. Referral binding is a core program rule, outside what support can adjust. Anyone claiming “internal channels” is almost certainly a scammer — never share your password or send money.
- “There’s a hidden entry in the App”: there isn’t. No version of the OKX App has an add-code entry. Tutorials that insist otherwise are likely confusing “view referrer” with “enter referral code”, or are simply outdated.
- “Redoing KYC resets it”: no. Referral binding and KYC verification are two independent systems; re-verifying doesn’t reset the referral binding.
So the conclusion is blunt: if you didn’t enter a code at signup, this account’s referral relationship is set in stone. The only “fix” is to close the current account and re-register (see “What if I entered the wrong code?” for the real cost). If you don’t trade much, don’t lose sleep over it — rebates are paid as a percentage of your actual trading fees, so the more you trade, the more you save; occasional small trades mean minimal impact. To understand how rebates are calculated and how much you could save, see How Exchange Rebates Work.
How do I confirm my referral code was bound successfully?
Registered but didn’t look closely? No problem — you can check the binding anytime. OKX shows the referral relationship in your account info, in plain sight:
- In the App: open the OKX App → tap the avatar / personal center in the top-left → go to “Settings” or “Profile” → find the “Referral” / “Referrer” entry. If it shows referrer info (or a code), the binding worked; if it shows “None” or is blank, no code was entered at signup.
- On the website: log in, click the avatar in the top-right → “Account settings” / “Profile” → view the referral relationship — same logic as the App.
Check on the day you register: your memory is fresh, and if the binding failed you can still re-register while the account is “clean” (no deposits, no KYC) at minimal cost. Discover it months later after deposits and trading, and re-registering costs far more.
What if I entered the wrong code?
Bad news first: a wrong code can’t be changed either — the same rule as entering none. Good news: if you haven’t really started using the account (no deposits, no trades, KYC not done or just done), it’s not a big deal — close the current account and re-register with the right code.
Before re-registering, take care of these:
- Move assets out first: if the account holds any crypto or fiat, withdraw everything to another wallet or account — you can’t recover it after closure.
- Unbind and close the account: find the account closure entry in the App’s settings and complete the process. Note that re-registering with the same phone/email after closure may have a cooling-off period, so have a backup email ready.
- Get it right on the second try: enter via a referral link (auto-fills the code), or manually expand “Referral code (optional)” and type OKCOOL, checking each letter before submitting.
If the wrongly-coded account is one you’ve used for a long time — KYC done, funds and trade history inside — do the math: re-registering means redoing KYC, moving funds, and losing trade history. Against “the extra rebate a correct code would earn”, it’s usually not worth the hassle. Not sure which code is reliable? Compare in the Exchange Referral Code Directory and pick a long-maintained one.
Referral code vs referral link — what’s the difference?
The most confusing pair for beginners. They’re essentially identical: both bind your account to a referrer — the only difference is how you use them:
| Referral link | Manual code entry | |
|---|---|---|
| What it is | A dedicated signup URL with the code embedded | An alphanumeric code (e.g. OKCOOL) |
| How to use | Click the link to open signup — the code fills itself in | Open the signup page yourself, expand “Referral code (optional)” and type it |
| Typo risk | Low — auto-filled | Medium — wrong letters or stray spaces can break the binding |
| When to use it | Links shared by friends, signup buttons in articles | Already on the signup page, or signing up inside the App |
| Binding result | Identical — referral relationship, rebate rate, and new-user perks are all the same | |
In one sentence: a referral link = a signup entry with the code pre-filled. Neither is better; use whichever is convenient. The one thing to avoid is ending up with neither: no referral link, and a forgotten manual entry — that’s voluntarily giving up the rebate.
FAQ
Q1: Can I change a wrongly entered referral code?
A: No. OKX offers no way to change a bound referral code — whether mistyped or skipped, the post-signup referral relationship can’t be altered. The only path is closing the account and re-registering; move your assets out first.
Q2: I registered without a code — what now?
A: Two options: ① accept it and keep the account — rebates accrue from trading, so light traders barely feel the difference; ② close and re-register with the code. Option ② is cheapest while the account is still “clean” (no deposits, no trades); for a deeply used account, do the math first.
Q3: Where can I find my own referral code?
A: After registering and logging in, open the “Invite friends” / “Referral” entry in the App to see your own referral code and referral link. Share it with friends — both sides get referral rewards per the official rules.
Q4: Do referral codes expire?
A: OKX referral codes generally stay valid long-term and don’t expire from disuse; but the new-user perks tied to the code may have claim deadlines, so complete KYC and check the tasks soon after registering. Details: Do Referral Codes Expire?.
Q5: Does entering a code guarantee rewards?
A: A code guarantees the referral binding; whether rewards land depends on the rules: fee rebates accrue from your actual trading — no trades, no rebates; new-user perks (mystery boxes, task rewards) usually require KYC or specific tasks. Reward types and conditions follow the latest OKX campaign pages.
Q6: Does registering with a referral code make fees more expensive?
A: No. Registering with a code doesn’t add a cent to your fees — your trading rates are identical to a direct signup. Rebates come from the platform’s own marketing budget rewarding both sides; it’s the platform sharing margin, not charging you extra.
Q7: How many OKX accounts can one phone/email register?
A: One phone number or email can register only one OKX account — which is also why a wrong code can only be fixed by closing and re-registering. You can’t just open a second “correct” account on the same number. To re-register, close the old account first or use another phone/email.
