Introduction

In today's digital age, privacy has become a significant concern for many individuals. As phone calls remain a primary means of communication, the ability to control your caller ID is crucial. This guide will delve into the various methods for blocking caller ID, helping you maintain your privacy while communicating.

Understanding Caller ID

Caller ID is a telecommunication service that transmits a caller's phone number and sometimes their name to the recipient's phone. While this service is useful for identifying who is calling, it can also compromise your privacy. Understanding how caller ID works is the first step to controlling it.

Caller ID data is sent during the ringing phase of a call.
The recipient's phone decodes and displays the information.
Caller ID can be blocked by the caller or the telecom provider.

Professional Reasons: Maintain anonymity during business calls.
