Hide your caller ID
You can hide your caller ID permanently, temporarily, or one call at a time, to prevent people from seeing your number and adding you as a contact. This may be important when using your personal cell phone for university business.
Use a caller ID block code
When calling from the US, hide your caller ID one call at a time by begin the call with *67 before entering the phone number (e.g., *67(507)555-1212). This will hide your number from the recipient. If possible, send a text or email message to anyone you are going to call in this manner, letting them know who you are, when you will be calling, and that your caller ID will be blocked.
Change your phone setting
Your carrier may allow you to hide your caller ID in your phone's settings (Fig 1). Not all carriers allow this.
Make your number private
Contact your carrier or visit their website to determine whether they can disable caller ID at the account level. There may be a fee for this service.
