Changing your phone number on OKX is a common need for users who want to update their contact information due to switching carriers, losing access to an old number, or enhancing account security. Whether you still have access to your original phone number or not, OKX provides clear and secure methods to help you successfully replace it. This guide walks you through both scenarios with easy-to-follow steps, important safety notes, and practical tips.
Why Update Your Phone Number on OKX?
Your phone number plays a crucial role in securing your cryptocurrency account. It’s used for two-factor authentication (2FA), login verification, and withdrawal confirmations. Keeping your contact details up to date ensures uninterrupted access and strengthens protection against unauthorized activity.
Common reasons users change their phone numbers include:
- Switching mobile service providers
- No longer having access to the original SIM card
- Using a temporary number during initial registration
- Security concerns after losing a device

Method 1: Changing Your Phone Number When the Original Is Still Active
If you can still receive SMS messages on your current registered number, updating it is straightforward and can be done directly within the OKX app or website.
Step-by-Step Instructions:
- Log in to Your OKX Account
Open the OKX mobile app or visit the official site and sign in using your credentials. - Navigate to Security Settings
Tap the profile icon in the top-left corner, then go to Security Settings. - Select "Phone Verification"
Under the security section, find the Phone Number option and tap Reset or Change. Verify Both Old and New Numbers
- Enter your new phone number
- Receive and input the SMS code sent to your new number
- Confirm by entering the SMS code sent to your old number
- You may also need to enter an email verification code for added security
- Confirm the Change
Once all codes are verified, click Submit or Confirm. The system will update your phone number immediately.
🔒 After changing your phone number, withdrawals are disabled for 24 hours as a security measure. This helps prevent unauthorized fund transfers if your account was compromised.
Method 2: Changing Your Phone Number Without Access to the Old One
Losing access to your original phone number doesn’t mean you’re locked out of your account. If you set up an email during registration, you can still recover and update your phone information.

Frequently Asked Questions (FAQ)
Q1: Can I change my phone number on OKX without email verification?
No. For security reasons, OKX requires multiple layers of verification when modifying sensitive account information. Even if you have access to your old phone number, you'll likely need to verify through your registered email as well.
Q2: How long does it take to change my phone number?
If you're using Method 1 (with access to the old number), the process takes just a few minutes. For Method 2 (without access), it may take up to 48 hours depending on support response time and verification requirements.
Q3: Is there a limit on how often I can change my phone number?
OKX does not publish a specific frequency limit, but frequent changes may trigger additional security reviews or temporary restrictions to protect your account.
Q4: Will changing my phone number affect my open trades or wallet balance?
No. Updating your phone number only affects authentication methods. Your trading positions, deposit history, and asset balances remain unchanged.
Q5: Why can’t I withdraw funds after changing my phone number?
As a protective measure, OKX disables withdrawals for 24 hours after any phone number update. This cooldown period reduces the risk of unauthorized withdrawals following potential account breaches.
Q6: Can I use a virtual or VoIP number for verification?
While some users attempt to use virtual numbers, OKX may block certain VoIP services for security purposes. It’s best to use a real mobile number from a recognized carrier.

- Re-enable two-factor authentication (2FA) using an authenticator app like Google Authenticator
- Review your active sessions and log out unfamiliar devices
