Why Change Your Phone Number on OKX?
Before diving into the process, it's essential to understand why users might want to unbind their current phone number:
- You’ve changed mobile numbers.
- Your old SIM card is no longer active.
- You're enhancing account security after potential exposure.
- You’re using a temporary number and now want to register a permanent one.
Regardless of the reason, OKX prioritizes account security, so any changes to critical information like your phone number require verification and may temporarily restrict certain functions — such as withdrawals.

Can You Fully "Unbind" a Phone Number?
It’s important to clarify: you cannot leave your OKX account completely without a phone number. Instead of “unbinding,” the correct term is replacing your current number with a new one. The system always requires either a phone number or email (preferably both) for two-factor authentication (2FA), login verification, and recovery options.
Therefore, the goal isn't removal — it's secure replacement.
Method 1: Changing Your Phone Number (Original Number Still Accessible)
If you still have access to your current registered phone number, the process is simple and can be completed directly within the OKX app or website.
Steps to Replace Your Phone Number:
- Log in to your OKX account via the official app or web platform.
- Tap on your profile icon in the top-left corner.
- Navigate to Security Settings.
- Select Phone Number Verification or Change Phone Number.
- Enter the new phone number you wish to register.
- Confirm by entering the SMS verification code sent to both your old and new numbers.
- Once verified, the old number is automatically replaced.
✅ This method is fast, secure, and typically takes less than 5 minutes.

Method 2: No Access to Original Phone Number? Here’s What to Do
Losing access to your original number — due to a lost SIM, carrier switch, or international move — doesn’t mean you’ve lost your account. However, recovery becomes more involved.
Step-by-Step Recovery Process:
- Log in using your email address instead of your phone number.
- After logging in, go to the Help Center or tap on Feedback & Support from the profile menu.
- Submit a request under Account & Security > Request to Change Bound Mobile Number.
Provide:
- A valid email address linked to your account.
- A working alternative contact number (if possible).
- A clear explanation of your situation.
- Wait for the OKX support team to review your case — usually within 24 hours.
⚠️ Note: Due to heightened security policies, withdrawals are disabled for 24 hours after changing your phone number. This applies regardless of method and helps prevent unauthorized access.
The support team may ask for additional identity verification, such as:
- A photo of your ID (for KYC-verified accounts).
- Proof of email ownership.
- Previous transaction history confirmation.
Once approved, your new number will be activated, and full account functionality will resume after the holding period.
Best Practices for Account Security on OKX
To avoid future issues and ensure smooth account management:
- Always link both a phone number and email during registration.
- Use strong passwords and enable two-factor authentication (2FA) via Google Authenticator or biometrics.
- Regularly update contact information before changes occur.
- Keep backup verification methods active (e.g., recovery codes, trusted devices).
By following these steps, you reduce the risk of lockouts and strengthen protection against phishing or SIM-swapping attacks.
Frequently Asked Questions (FAQ)
Q1: Can I remove my phone number completely from OKX?
No. OKX requires at least one verified contact method — either a phone number or email — for security and recovery purposes. You can only replace your current number with a new one.
Q2: How long does it take to change my phone number?
If you have access to your original number, the change is instant. If submitting a support ticket, allow up to 24 hours for processing.
Q3: Why are withdrawals disabled after changing my phone number?
This is a security measure. OKX blocks withdrawals for 24 hours after sensitive changes to prevent unauthorized fund transfers in case of account compromise.
Q4: What should I do if I can’t log in at all?
Try logging in with your email. If that fails, use the “Forgot Password” feature and follow the recovery prompts. Make sure your recovery email is accessible.
Q5: Is it safe to change my phone number on OKX?
Yes — as long as you do it through official channels (app or website) and never share verification codes with anyone. Always verify URLs to avoid phishing sites.
Q6: Do I need KYC verification to change my phone number?
Not necessarily for simple changes with original number access. However, if you’ve lost access and need manual support, KYC documentation may be required for identity confirmation.
Changing your phone number on OKX is designed to balance convenience and security. Whether you're upgrading your contact info or recovering access, the platform provides clear pathways — just remember that safety comes first.
Always perform these actions through the official OKX app or website, keep your recovery options updated, and never share sensitive codes or login details.
