When you set up caller identification, your mobile number or Skype Number is displayed when you call mobiles and landlines from Skype.
Caller identification is free to set up and use.
Enter your mobile number in the text box and click Verify number.
Does Skype use phone number or email?
Your Skype name is the username you created when you first joined Skype, other than your email address or phone number. If you sign in with an email address or phone number instead, then you have a Microsoft account, not a Skype Name.
How do I know what my Skype number is?
Sign in to Skype. Select the “Caller ID” tab and enter your mobile number. This will become your phone number identifier, and it will be shown when you make a call from Skype.
Can Skype number be traced?
Well, it depends. For instance, Skype is VoIP telephony that uses a proprietary peer-to-peer protocol, which makes calls hard to trace. If your primary concern is making sure calls can’t be traced to you, create a throwaway email address and use it only for making Skype calls.
