How to Unbind Your Phone Number from OKX Exchange?

In today's digital age, many cryptocurrency traders use OKX (formerly OKEx) Exchange for their transactions. Two primary registration methods are supported: mobile number registration and QQ email registration. While both options provide quick and convenient access, users occasionally need to change their registered phone number. This guide explains the step-by-step process for unbinding your phone number from OKX Exchange.

Reasons for Unbinding Your Phone Number

Users typically need to unbind their phone numbers for two scenarios:

1. Active Number Replacement: When switching to a new phone number while the old one remains functional
2. Inaccessible Number Recovery: When the original number becomes unavailable (lost, stolen, or deactivated)

Method 1: Unbinding When Original Number Still Works

For users who can still access their registered number:

1. Log in to your OKX account
2. Click the profile icon in the top-left corner
3. Navigate to "Security Settings"
4. Select "Mobile Verification"
5. Click "Reset" and enter your new phone number
6. Input the SMS verification code sent to your new number
7. Click "Confirm" to complete the rebinding process
