This guide walks you through both scenarios with detailed steps, security tips, and frequently asked questions to ensure a smooth transition.

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.

Method 1: Original Phone Number Still Accessible

If you can still receive SMS on your current registered number, you can directly update your phone number within the OKX app or website.

Step-by-Step Instructions:

  1. Log in to Your OKX Account
    Open the OKX website or mobile app and log in using your credentials.

  3. Select "Phone Verification"
    Under the account security section, find the Phone Verification option and click on Reset.

  4. Enter Required Verification Codes
    You’ll be prompted to provide:

    • Your new phone number
    • SMS code sent to the new number
    • SMS code sent to the old (original) number
    • Email verification code
  5. Confirm and Save Changes
    Once all codes are verified, click Confirm or Submit to complete the binding process.

✅ This method is fast and fully automated, typically completed within minutes.

Method 2: Original Phone Number No Longer Available

Losing access to your old number doesn’t mean you’ve lost access to your account. OKX offers a recovery pathway through customer support.
