Some pet sitters are worried about providing their mobile number on Pawshake. SMS verification is an obligatory safety barrier for all user, so you have to complete it in order to use the Pawshake platform.
However, your number is not displayed in your profile and you are in full control about passing it on to pet parents. When you receive a new enquiry that you wish to pre-approve, you can choose whether or not to pass on your mobile number to the pet parent. If you don't want to do so at that point in time, you can include it in a message later on.
