Updating your contact information is a routine but important part of maintaining the security of your digital asset accounts. If you are using OKX and need to modify your registered mobile number, this guide provides clear and secure methods to do so.
Whether your current number is still accessible or you've lost access to it, the platform offers dedicated procedures to handle both situations. Following the correct steps ensures a smooth transition and helps protect your account from unauthorized access.
Method 1: Changing Your Number with Access to the Old One
This is the standard and fastest process if you can still receive SMS codes on your currently registered mobile number.
- Log in to your OKX account. Once on the dashboard, locate and click on your profile icon in the top left corner of the screen.
- From the menu that appears, navigate to Security Settings. This section manages all your authentication methods.
- Find the Mobile Verification option and select the Reset button next to it.
You will be prompted to enter several pieces of information for verification:
- Your new mobile number.
- The SMS verification code sent to that new number.
- The SMS verification code sent to your original (old) mobile number.
- An email verification code sent to your registered email address.
- After carefully entering all required codes, click Confirm to finalize the change.
Method 2: Changing Your Number Without Access to the Old One
If you can no longer use your old number, you will need to contact customer support to verify your identity and initiate the change.
- Using Email Login and In-App Feedback: If you can still access your registered email, use it to log in. Go to your profile icon and select Help & Support or Feedback. Submit a request, categorizing it under Account and Security Issues and specifically choosing Apply to Change Bound Mobile. Clearly describe your situation, provide a current contact method, and submit the ticket for the support team to assist you.
- Direct Email Support: If you cannot log in to your account at all, the most direct method is to send an email to the platform’s official support address from your registered email. Explain in detail that you have lost access to your mobile number and need to update it. Be prepared to provide information to verify your identity as the account holder.

Important Security Notice
After successfully changing your mobile number, note that withdrawal functions will typically be suspended for a 24-hour period. This is a crucial security cooldown feature designed to protect your assets from malicious actors in case of unauthorized account access.
Always ensure you are logged into the official OKX website or app before attempting any security modifications. Never share your verification codes, passwords, or two-factor authentication details with anyone.
Frequently Asked Questions
How long does it take to change my mobile number?
The process itself is instant if you have access to both your old and new phones. However, if you need to go through customer support, the time can vary depending on request volume, but they aim to resolve issues promptly.
What information do I need to provide to support for verification?
To protect your privacy, support will never ask for your password. However, be prepared to provide information that proves you own the account, which may include details about registration, past transactions, or identity documentation linked to your account.
Can I use the same mobile number on multiple OKX accounts?
No, a single mobile number can only be bound to one OKX account at a time for security reasons. You must unbind it from one account before you can link it to another.
What should I do if I don’t receive the SMS verification code?
First, check your mobile signal and ensure you have not blocked OKX's messages. If the issue persists, you can request the code to be sent again. Using the audio verification call option can also be a helpful alternative.
Why is there a 24-hour withdrawal hold after a number change?
This security measure is in place to prevent a bad actor who may have temporarily gained access to your account from immediately draining your funds. It gives you a window to detect and report any unauthorized changes.
