When calling a number from a Verizon Wireless cell phone your number, and in some cases, your name appears on the recipient’s cell phone screen or caller id box. To maintain privacy or prevent the person you are calling from seeing your telephone number, you can use Verizon’s calling services to temporarily block your number during a single call, or set the service to hide your number for every outgoing call. When in use, your number shows up simply as “Private,” “Unknown” or “Anonymous.” Writer Bio
