Wix store : How to set validation for phone & postal code in address ?

When customer adds addresses in “My Address” members page, currently there is no validation for address fields.
I would like to restrict Phone number to 10 digit & Postal code to 6 digit.
Could someone tell me how to do this.

At this moment, it is not possible with Coding or else. What makes you want this feature?

Thanks for your reply.
This is needed just to avoid unnecessary / false values.
is it possible to do mobile number validation using OTP ?

@mayonstudioz I see, my suggestion (by coding)

Check all users personal data validity daily , if the details do not meet your expectation, the code sends an email to ask for OTP, plus the account is temporarily blocked. Then, the user proceeds to OTP, if verified, the code send u an email to ask you to unblock them manually (currently this part can’t code)

The OTP needs 3rd party platform = u need to pay for the SMS fee before releasing the system.
