How to check if the number is registered in VK through VK API?

Question

Python

How to check the number for registration in VK? I tried to use the auth.checkPhone method but it doesn't work.

Answer 1

Phone numbers are confidential information, and VK carefully hides them.
Therefore, even just getting the user's phone number is not possible if it is hidden on the page.
Alas, it won't work.
