Google, Facebook, and Twitter all require verification of your business and they like to do this via the business owner's cell telephone number, this way you are the owner of these pages. It will in no way be published or distributed although you may get verification messages about your pages. This SHOULD be the owner of the business and NOT an employee, whoever has control over the verification process can take over the account in the event of a disputed termination, etcetera, we've seen it happen and it is not necessary if the business owner is this contact.
