You can change your phone number in the
Security and login section of your VK Connect account page.
If you don’t have access to the old number that you linked, the system will ask you to wait for seven days, after which the number will be changed.
If you don’t want to wait seven days, you can fill out
this form.
If you follow the system’s instructions, but you still can’t link a number, please contact Support. Indicate your phone number and provide a link to the account to which you want to link it.
