Forgot the OKX referral code?
Once the account exists, it can’t be added.
OKX only takes a referral code before your account is created: its Referral Program FAQ says it won’t be possible to add or change the code once the account has been created. If you haven’t tapped Sign up yet, you can still fix it. If you have, the account works as normal without one, and OKX tells you not to close it or open a second account to get a different code.
Forgot the OKX referral code? It depends on whether you’ve tapped Sign up
Only one thing decides whether you can still enter a code: has your account been created yet? OKX’s Referral Program FAQ (updated 5 October 2026) is plain about it: referral codes must be added before the account is created, and “it won’t be possible to add or change the referral code once the account has been created.”
| Where you are | Can you still add it? | What to do |
|---|---|---|
| Still on the sign-up page, haven’t tapped Sign up | Yes | Expand the “Referral code (optional)” field and enter the code. If there’s no such field, open the sign-up page through a referral link instead |
| Someone else’s code is already in the field | Yes, before you submit | Delete it and type the code you want. If it keeps coming back, reopen the referral link in a private window |
| Just signed up, not verified, no trades yet | Usually not | OKX says a code can’t be added once the account exists. You can ask Support inside the app, with your UID, but don’t expect a different answer |
| Already verified, or already trading | No | Keep using your account as it is. OKX says the relationship can’t be changed once registration or identity verification is complete |
| Thinking of closing the account, or opening a second one, to use another code | Don’t | OKX tells users not to delete an account or create another one to change a referral code. What it would cost you is explained below |
Not signed up yet? Tap the button and referral code OK66688 is added for you, no typing needed. Only if you register inside the app yourself do you enter OK66688 by hand. OKX’s sign-up page shows a 20% trading-fee discount (checked 2026-10-16); new-user rewards are as shown on the event page.
Still on the sign-up page, and the code won’t go in?
If you haven’t tapped Sign up yet, it’s almost always one of these, and most can be fixed on the spot. Questions 17 and 18 of the OKX Referral Program FAQ (updated 17 September 2026) cover several of them, and OKX’s Referral Program FAQ (updated 5 October 2026) explains pre-filled codes:
| What you see | Likely reason | What to do |
|---|---|---|
| There’s nowhere to enter a code | The referral field is optional and starts collapsed | Expand “Referral code (optional)”. If it isn’t there at all, OKX suggests signing up through the referral link |
| You opened a referral link on your phone, but the code didn’t carry over | You downloaded the app separately and signed up inside it, so the link’s code got lost | OKX says you may need to enter your email on the invite page first, then sign up with the same email. Or type OK66688 into the app’s sign-up form yourself |
| Someone else’s code is already in the field | You opened another referral link, or downloaded an app carrying a code, in the past 30 days, and that code may be linked to your device | Open the referral link you want in a private window and check the field before you submit |
| The code didn’t fill in after you’d opened an ad or another campaign page | OKX says a sign-up page opened earlier through an ad or another channel can take the attribution | Type the code into the field yourself and check it before you submit |
| “Invalid code” or “code does not exist” | A zero instead of the letter O, a stray space, or full-width letters | Go through the six reasons OKX says a referral code is invalid |
| “This email or phone number is already registered” | You already have an OKX account, and going through sign-up again won’t create a new one | Codes only apply to new sign-ups. The next section covers accounts that already exist |
Can you add an OKX referral code after sign-up?
No, going by OKX’s own help center. Two of its articles are direct about it:
- Referral Program FAQ (published 8 January 2025, updated 5 October 2026): “Referral codes must be added before invitees create their accounts. It won’t be possible to add or change the referral code once the account has been created.” The same article says referral relationships can only be set up at registration and can’t be changed once registration or identity verification is complete.
- OKX Referral Program FAQ, question 13 (updated 17 September 2026): after registration, the referral relationship “usually can’t be added or changed. Don’t delete the account or create another account to try to change the referral code.” Question 17 adds that the code must be applied before sign-up is completed and can’t be added afterwards.
Neither article mentions an add-code option, a grace period or a request form, and as of 2026-10-18 we can’t find any OKX page that does. If you still want to check your own account, go in this order:
- Ask Support inside the OKX app. Say you missed the referral code at sign-up and give your UID and sign-up date. Asking costs nothing, but don’t expect a different answer from what the help center says.
- If the answer is no, leave it there. Your account works exactly the same without a code; you just don’t get the trading-fee rebate that comes with one.
- Ignore anyone offering to “rebind” a code. People who message you first, ask for your password or verification codes, or want you to install a remote-access app are scammers, whatever they call themselves.
Not sure whether a code is on your account at all? OKX’s Referral Program FAQ says to open Menu → Account settings → Profile → Referral rewards in the app. If that entry is there, a referral relationship exists; if it isn’t, either none was set up or your referrer isn’t an OKX affiliate.
Claims you’ll see online, like “you can still add a code within 7 days” or “before your first deposit”, have no source in OKX’s help center as of 2026-10-18. Don’t close an account or sign up again because of them.
Why not close the account and sign up again, or open a second one?
Because OKX tells you not to, and it wouldn’t get you what you want anyway. Question 14 of the OKX Referral Program FAQ (updated 17 September 2026) says deleting an account and signing up again “doesn’t restore the original referral relationship, Referral eligibility, or New User Bonus eligibility”, and that registering multiple accounts or using someone else’s account or identity breaks the program rules. Here’s what starting over would cost you:
| What’s affected | What OKX says | What it means for you |
|---|---|---|
| Your current account | A closed account is closed permanently and can’t be retrieved. If you might want it again, OKX suggests freezing it instead | You lose the account and access to its order and statement history |
| Your funds | All assets have to be moved out or dealt with and all open orders completed or cancelled first. A small balance you can’t withdraw or convert is gone for good once it’s forfeited | Trading, Grow and connected Web3 wallet balances all have to be emptied, and dust you can’t move is lost |
| Your email, phone number and ID | If you ever started identity verification (including a pending, failed or returned application), a cooling-off period follows closure: 3 days in Korea, 30 days in Turkey, 7 days everywhere else | Until it ends, you may not be able to register or verify a new account with the same details |
| New-user rewards | Signing up again doesn’t restore New User Bonus eligibility | There’s no second round of new-user rewards |
| A second account instead | Under each OKX entity’s terms of service you can hold only one account, and each ID document can verify only one account. If a new account’s ID matches a verified one, OKX has you recover the verified account instead: the new, unverified one is closed for good, and its referral relationship and coupons don’t carry over | A second account can’t be verified with the same ID, and its new code wouldn’t follow you back |
| Referral rewards | OKX’s Referral Program FAQ lists registering multiple accounts among the behaviour that can get a user disqualified from rewards | Opening accounts to swap codes can cost you the rewards a new code was meant to bring |
Closing an account can’t be undone. For most people, a different referral code isn’t worth losing an account, sitting out a cooling-off period and giving up new-user rewards, especially if you don’t trade much. For a rough idea of what a code is worth to you, try the fee calculator. Only ever verify with your own ID, and do it yourself. Never use a family member’s or anyone else’s identity.

Forgot the referral code?
FAQ.
01Can I add an OKX referral code after signing up?
No. OKX’s Referral Program FAQ (updated 5 October 2026) says referral codes must be added before the account is created, and it won’t be possible to add or change the code once the account exists. As of 2026-10-18 we can’t find any OKX page describing a way to add one later. You can ask Support inside the OKX app, with your UID, but don’t expect a different answer.
02I forgot the referral code. Can OKX Support add it for me?
You can ask, but don’t count on it. OKX’s help center says that after registration the referral relationship usually can’t be added or changed. Only contact Support from inside the OKX app. Anyone who messages you first offering to “rebind” a code is a scammer, so never give them your password, verification codes or remote access to your phone.
03Can I change the referral code on an existing account?
No. OKX says the referral relationship can’t be changed once registration or identity verification is complete. If someone else’s code was already in the field when you signed up, it stays on the account.
04Should I close my account and sign up again with a different code?
No. OKX tells users not to delete an account or create another one to change a referral code, and says signing up again doesn’t restore referral or New User Bonus eligibility. Closing is permanent, and if you ever started identity verification, your email, phone number and ID are locked for a cooling-off period afterwards (7 days in most regions).
05Can I open a second OKX account just to use a new code?
No. OKX’s Multiple accounts FAQ says you can hold only one account and each ID document can verify only one account. Never verify an account with a family member’s or anyone else’s ID.
06How do I check whether my account has a referral code?
In the OKX app, go to Menu → Account settings → Profile → Referral rewards. OKX says that if this entry is there, a referral relationship exists; if it isn’t, either none was set up or your referrer isn’t an OKX affiliate.
