Support XFINITY Voice Block Your Name and Number from Displaying on Caller ID

Introduction

Did you know you could block the receiving party’s Caller ID from displaying your name and number? It's perfect for when you need to make an anonymous phone call.

How it works

With Caller ID Blocking Per Line or Per Call, your name and number appears either as “Private” or “Anonymous” on the other person’s Caller ID displays. Use it to anonymously make phone calls or to protect your unlisted number. Sometimes, the receiving party blocks calls marked “Private” — when this happens, you can temporarily cancel Caller ID Blocking Per Line, (which will automatically be restored for the next call).

Change your Caller ID Blocking default setting
