Caller ID is a feature on cell and landline phones, which prevents your personal information from being displayed on the phone you are calling. This feature is strictly for privacy reasons, as you want no one to know of your whereabouts or who you are. Your name and phone number appear on the caller ID feature on the phone that you are calling, if it is equipped with this feature. If you want your private information to appear on the phone you call, you can disable the caller ID blocking on both a landline and a cell phone.
