OKX sign up in short: six steps
Creating an OKX account follows the same order on the website and in the app. This is the sequence in OKX's own sign-up guide (updated 11 August 2026):
| Step | What you do | What to check |
|---|---|---|
| 1. Open the sign-up page | Click a sign-up button on this site, or tap “Sign up” in the OKX app | The page is on okx.com |
| 2. Choose your country or region | Pick where you live, tick the box for OKX's Terms of Service, Risk and Compliance Disclosure and Privacy Notice, then select “Create account” | It's the country you actually live in |
| 3. Enter your email and referral code | Type your email address; the referral code field is optional | Through our button it already shows OK66688; in the app you type it |
| 4. Confirm the email code | Enter the code OKX sends to your inbox | Look in spam or promotions if it's missing |
| 5. Add your phone number | Choose the country code and enter the number, then “Verify now” on the web or “Next” in the app | A number you own and will keep |
| 6. Confirm the SMS code | Enter the code sent to your phone, then set a password when the page asks for one, and registration is complete | Next: security settings and identity verification |
Your account exists after step 6, but it can't do much yet. OKX says you can trade, deposit and withdraw only after identity verification, which is covered briefly below.
Check your country before you create an account
OKX isn't one company everywhere. Which OKX company serves you, which products you get, and whether you can open an account at all depend on where you live, not on which link you click. Check this before anything else:
| Where you live | What OKX's own pages say | What to do |
|---|---|---|
| United States | Residents of OKX US's approved US locations are served by OKX Inc. (“OKX US”) under separate terms; OKX's other centralized exchange services aren't available in the US | Use OKX US and its own sign-up. Our button opens OKX's global sign-up, so it isn't for you |
| Restricted locations | Afghanistan, Canada, Cuba, Hong Kong, Iran, India, Japan, Malaysia, Nepal, North Korea, Syria, Uzbekistan, the Crimea, Donetsk and Luhansk regions of Ukraine, and certain US jurisdictions including all US territories such as Puerto Rico | Don't sign up, through our link or anyone else's |
| Some services limited | For example derivatives, CeFi and P2P services in the United Kingdom; derivatives and P2P in Brazil and South Korea; derivatives and CeFi services in Australia | You may be able to register, but those products won't be offered to you |
| Everywhere else | The sign-up page shows what's available for the country you choose | Pick the country you live in and read the terms it shows |

Don't pick a country you don't live in. The country you choose has to match the ID and address you verify with later, and OKX says it may restrict or prohibit use of its services from restricted locations. An account opened against the terms can be restricted when OKX checks it, and we don't suggest signing up through any link, ours included, if OKX doesn't serve your country.
How to register on the OKX website, step by step
- Open the sign-up page through our buttonAny “Sign up” button on this site opens top.bianve.com/ok, which takes you to OKX's sign-up page with OK66688 already in the referral field. Check that the address bar shows okx.com before you type anything.
- Choose your country or region and accept the termsPick where you live, read and tick the box for OKX's Terms of Service, Risk and Compliance Disclosure and Privacy Notice, then select “Create account”.
- Enter your email and check the referral codeUse an email address you'll keep. A personal address is fine; OKX sends important notices, verification messages and password recovery there. The “Referral code (optional)” field should show OK66688. Then select “Sign up”.
- Enter the email verification codeCopy the code from OKX's email. If it's slow, check spam and promotions folders before asking for a new one.
- Add your phone number and select “Verify now”Choose the right country code and enter a number you actively use.
- Enter the SMS code and set a passwordOKX's How do I register an account on OKX? (updated 12 October 2026) shows a Password field after the phone code. Pick one you don't use on any other site, select “Next”, and registration is complete. Before you move any money, turn on the security settings and verify your identity as described below.
Click the button to sign up and OK66688 is applied automatically, nothing to type. Only if you register inside the app do you enter OK66688 yourself. If you live in the US or a restricted location, don't use it.
Sign up with OK66688 ↗How to create an OKX account in the app
The app asks for the same things in the same order. The one difference that matters: in the app nothing fills in the referral code for you.
- Install the official appUse the official store listing or okx.com/download; see OKX app download. On Android without Google Play, OKX APK download explains how to get the real file.
- Tap “Sign up”, choose your country or region and accept the termsThen tap “Create account”.
- Enter your email and type the referral codeEnter OK66688 in the referral code field yourself before you continue.
- Confirm the email code, add your phone number and tap “Next”Enter the SMS code, set a password when the app asks for one, and the account is created.
Simpler order: create the account through our web button first, so the code can't be missed, then install the app and log in with the same email.
Can you create an OKX account without a phone number?
No. OKX's sign-up guide says new accounts must bind both a mobile phone number and an email address, and each is confirmed with its own code before registration finishes. If a guide tells you to choose “email or phone”, it doesn't match what OKX's own guide says today.
| What OKX asks for | What it's used for | What to use |
|---|---|---|
| Email address | System notices, identity verification and password recovery; OKX says all important notifications and verification messages go to your email | A personal address you'll keep; some work email servers filter codes |
| Mobile number | The SMS code you confirm during sign-up | A number in your own name that you actively use |
| One account each | Each phone number and each email address can register only one OKX account | If OKX says one is already registered, recover that account instead |
Don't register with a friend's number, a temporary number or a number you're about to give up. If you lose access to it, getting back into your account becomes much harder, and whoever controls that number can receive codes meant for you.
Where the referral code goes, and why it has to be at sign-up
- On the web, through our button: the “Referral code (optional)” field already shows OK66688. Check it before you select “Sign up”.
- In the app: type OK66688 into the referral code field on the screen where you enter your email.
- Leaving it blank: OKX says leaving it blank doesn't affect registration. You just won't be linked to a referrer.
- Adding it later: not possible. OKX's Referral Program FAQ (updated 5 October 2026) says referral codes must be added before the account is created and can't be added or changed afterwards. Closing the account or opening a second one isn't a way around it, because OKX allows one account per user under the same OKX entity.
What the code gets you: OKX's sign-up page shows a 20% trading-fee discount (checked 2026-10-16). OKX's guide adds that referred new users may receive rewards after completing the required tasks, under the campaign rules; new-user rewards are whatever OKX's campaign page shows at the time.
A referral code isn't a verification code. A referral code is fine to share. The codes OKX sends you by email and SMS are not: anyone who asks for one, including someone claiming to be OKX support, is trying to take over your account.
After you register: identity verification in brief
OKX says you can trade, deposit and withdraw only after completing identity verification, and you must be at least 18. Its verification guide (updated 25 August 2026) gives these steps:
- Open identity verificationOn the web: the verification page from your profile icon. In the app: Menu → Account settings → Identity verification.
- Fill in your detailsCountry of residence, nationality, full name, date of birth, ID details and address.
- Upload your IDA valid, unexpired government ID with all four corners visible. OKX doesn't accept screenshots.
- Do the face checkKeep your whole face inside the oval, without a mask, glasses or hat.
- Wait for the reviewOKX says it reviews applications within 24 hours. Some users are also asked for proof of address.
Verify only inside the official app or on okx.com. One ID can be linked to only one OKX account, and OKX says a completed verification can't be changed or cancelled. Anyone who asks for your ID photos or a selfie over WhatsApp, Telegram or email, or offers to do the verification for you, is running a scam.
Code not arriving, or “already registered”?
- Email code: check spam and promotions folders; some work email servers filter codes.
- SMS code: check the country code and your phone's blocked-messages folder, then wait a minute before resending.
- “Already registered”: that email or number already belongs to an OKX account. Use password recovery or contact OKX support; the same email or number can't open a second account.
- Still stuck: OKX's guide suggests checking what you typed and switching to another network.
First thing after signing up: three security settings
- Authenticator app (2FA)Needed to log in and withdraw, so a leaked password alone isn't enough to take over your account.
- Anti-phishing codeGenuine OKX emails will include it. An email without it isn't from OKX.
- Withdrawal whitelistWithdrawals can only go to addresses you've approved. You won't find a separate fund password: OKX's Chinese help centre says it was retired from app version 6.0.24, and your login password and 2FA now protect the account together.
Once that's done, the next step is buying your first USDT, and OKX fees explained shows what each trade costs.

OKX Sign Up: FAQ
Can I create an OKX account without a phone number?
No. OKX's sign-up guide (updated 11 August 2026) says every new account has to bind both a mobile phone number and an email address, and each one is confirmed with its own code before registration finishes. Use a number you own and will keep: each phone number and each email address can be used for only one OKX account, and a borrowed or temporary number can lock you out later.
Can I sign up for OKX in the US?
Not on OKX's global platform. OKX's Terms of Service (last updated 17 September 2026) say residents of OKX US's approved US locations are served by OKX Inc. (“OKX US”) under separate terms, and OKX US's disclosures (updated 18 June 2026) say OKX's other centralized exchange services aren't available in the United States. Our button opens the global sign-up, so it isn't meant for US residents.
Which country should I choose when I register?
The country or region where you actually live. It decides which OKX company serves you and which products you see, and it has to match the ID and address you verify with later. If OKX lists where you live as a restricted location, don't open an account, through our link or anyone else's.
Can I add a referral code after I register?
No. OKX's Referral Program FAQ (updated 5 October 2026) says referral codes must be added before the account is created and can't be added or changed afterwards, and its sign-up guide says referral relationships are confirmed only through the code. Don't delete your account or open a new one to get a code onto it: OKX's Multiple accounts FAQ (updated 2 October 2026) allows one account per user under the same OKX entity. If you register through our button, OK66688 is already filled in.
How many OKX accounts can I have?
Each phone number and each email address can register only one OKX account, and one identity document can be linked to only one account. OKX also says a completed identity verification can't be changed or cancelled, so never verify with someone else's ID or let anyone else verify on your account.
Do I have to verify my identity after signing up?
Yes, if you want to use the account. OKX says you can trade, deposit and withdraw only after identity verification, and you must be at least 18. Its verification guide (updated 25 August 2026) says applications are reviewed within 24 hours.
