OKX Referral Code NEXU888: How to Sign Up for OKX (October 2026)

What you need before you start

• A mobile phone number that can receive SMS codes. OKX requires you to bind a phone number and an email address when you register.
• An email address that can receive verification messages.
• Age 18 or older. OKX's help centre says that after registration you must complete identity verification and be at least 18 years old.
• A stable connection and a browser or app you already use for everyday logins.

Check these three items before you start. If the phone or email is not reachable during sign-up, the flow stops at the verification step and you will need to start again with the same details.

Sign up on the OKX website

1. Go to the OKX website and select Sign up.
2. Select your country or region.
3. Read the Terms of Service, the Risk and Compliance Disclosure and the Privacy Notice, tick the agreement box and select Create account.
4. Enter your email address and the referral code NEXU888 in the optional referral code field, then select Sign up.
5. Enter the email verification code you receive.
6. Add your phone number. Choose the correct country code, then select Verify now.
7. Enter the phone verification code. Registration is complete.

Sign up in the OKX app

The app follows the same order. Open the app, select Sign up, choose your country or region, agree to the three documents and tap Create account. Enter your email and the referral code, tap Sign up and enter the email code. Add your phone number with the correct country code, tap Next and enter the phone code. OKX's help article for the app and the website is the same flow with different button names.

Where the referral code goes and why timing matters

The referral field sits on the email step of the sign-up form. According to OKX's help centre, you can use either a referral link that a friend shares or a referral code typed into the field. Three rules matter here.

• The code must be added before the account is created. OKX says it cannot be added or changed after the account exists.
• If the code does not fill in automatically, type it into the referral field by hand.
• A code can be pre-filled from an earlier visit to a referral page. Read the field before you continue. OKX suggests a private or incognito browser window if you want a clean start.

For readers who only want a simple path: open the sign-up page with our OKX link, check that NEXU888 appears in the referral field, and then continue. If the field is empty, type the code yourself before tapping Sign up.

Identity verification comes next

Registration is only the first step. OKX states that accounts which have not completed identity verification cannot buy or sell crypto, deposit or withdraw assets (including internal transfers), borrow, or transfer funds. Plan this step before you need the account for a trade. Do not wait until a market move, because verification can take time on its own schedule. After you log in, look for the verification prompt in the account settings and complete it with the documents the page asks for.

Country and access checks

OKX's help article carries a note that the information may not apply to all customers. Products, features and rules differ by country and by entity. Before you rely on a feature, log in and check whether it applies to your account, as OKX recommends. The sign-up steps above describe the standard web and app flow; they do not promise that every product is open in every market.

Common sign-up problems

If the sign-up page does not load or the codes do not arrive, switch networks, for example from Wi-Fi to mobile data, and try again on a stable connection. If a verification code expires, request a new one rather than reusing an old message. If the referral field shows the wrong code, clear the field, type the code again and check it before you press Sign up. Once the account exists, the referral code cannot be changed, so a wrong code has to be fixed before the final step.

Keep the account safe from day one

Use a unique password that you do not use anywhere else, and turn on the security features OKX offers in the account settings. Do not share your verification codes with anyone. Never enter your password on a page that you reached from a message or an advertisement without checking the domain first. These steps protect the account whether or not a referral code was used.

How to act on this

If you want to open an OKX account, sign up with NEXU888 through our OKX page and keep the verification step in mind. Before you move money, compare the spot and futures fee tables on the OKX exchange profile. Partner benefits change by campaign and by market, so the campaign terms on the exchange's own page decide what you receive. Read them before you deposit.

Quick answers

Do I need a referral code to register? No. The field is optional, and leaving it blank does not affect registration.

Can I add a code after I have signed up? No. OKX says the referral code must be added before the account is created.

Can I register with only an email? No. OKX requires both a mobile phone number and an email address.

When can I start trading? After identity verification is complete. Accounts without it cannot buy or sell crypto, deposit or withdraw.

Which age is required? OKX says you must be at least 18 years old.

What we could not verify

The OKX help article does not list the referral rewards for every country, and it says the campaign page prevails. We did not verify which campaigns are live in your market today. Check the current terms on the exchange before you sign up.
