How are my contact details used in Skype?

In your Skype profile, you can add a mobile phone number. You aren't required to have one, but if you do, Skype can use it to display when you call mobiles and landlines if you set up caller ID.

You can also choose to be searchable by the phone number you have saved to your Skype profile, unless you opt out of search. If you want to change or remove your phone number in Skype, you can do that in your Skype profile.

When you add a mobile number to your Skype profile, you will need to verify your phone number.
