You can change your registered Phone number directly from the Delta Exchange website or the Delta Exchange app. 

Before trying to update your phone number, please ensure that your account is KYC verified. Only KYC-approved users will be able to see the “Edit” option in the Profile section.

Here's how:

1. Log in to your Delta Exchange account via the website.
   
   
2. Go to the Profile section  

       3.  Click on the Edit icon beside your current Phone number.

       4. Enter your New Phone number in the designated field.

       5. You will receive an OTP on your new Phone number.

       6. Enter the OTP.

       7. You will be prompted to complete a selfie verification to confirm your identity.

       8. Once both the OTP and selfie are verified, your new Phone number  will be updated.

Note : You will be allowed to update your Phone number only 3 times during your account lifetime. Please use this feature only when absolutely necessary to avoid reaching the limit.
