Should Singapore Users Choose Phone Number or Email to Register on OKX?
For Singapore users, both phone number and email are viable entry points for registration, but based on real-world usage, we recommend registering with email. Email is more stable than a phone number – you don't have to change it when switching carriers, receiving verification codes doesn't depend on signal strength, and it effectively avoids issues with SMS interception or carrier filtering that can prevent code delivery.

1. Understand first: both methods can register, not an either-or choice
Understand the role of phone number and email in the registration process; there is no mutual exclusivity that forces you to use only one.
OKX supports both phone number registration and email registration, and you can create an account either way. The safest approach: register with one method first, then after registration, bind the other to your account, so both are linked.
You need to understand that phone number and email are not mutually exclusive. Use one to register first, and later add the other as a supplementary binding.
Prerequisites: None.
Common failure reason: Only binding a phone number. When you change your phone number later and realize there's no backup verification method, password recovery can only go through the phone route, making the process very tedious.
2. Singapore users should prioritize email registration
In the Singapore context, choose the "Email Registration" entry instead of defaulting to phone number.
Singapore users using domestic email services like QQ or 163 may experience verification code delays or have them land in spam. We recommend international email providers like Gmail or Outlook for more stable code delivery. When registering, select the "Email Registration" path, enter your email address, receive the verification code, and complete verification.
Completion standard: Your email receives the verification code from OKX, and you successfully complete verification to proceed to the next step.
Prerequisites: You can log into your email normally; check both inbox and spam folder.
Common failure reason: The verification code is classified as spam and goes unnoticed. If you don't receive the code, check the spam folder first and avoid repeatedly clicking "Resend".

3. Bind your phone number after email registration
After completing email registration, go to account security settings and bind your Singapore phone number, so both verification methods are associated with the same account.
After logging in, go to [Security Center] → [Account Security], find the "Bind Phone Number" or "Phone Verification" option, enter your Singapore phone number, select the +65 country code, receive the SMS verification code, and complete the binding.
Completion standard: The Security Center shows both phone number and email are bound with the status "Verified".
Prerequisites: Email registration was successful and the account can be logged in normally.
Common failure reason: Choosing the wrong country code. Singapore's code is +65, not +86.
Follow-up action guide: When registering, choose the "Email Registration" method and use Gmail or Outlook to create your account. Once registration is successful, immediately go to Security Center to bind your Singapore phone number. The advantage of this approach is that no matter whether you change your phone number or email later, your account always has an alternative verification channel available, preventing password recovery issues.
