Hiding your phone number on WhatsApp is a privacy feature that allows you to communicate with others without revealing your personal contact information. This can be useful for various reasons, such as protecting your privacy when communicating with strangers, preventing spam calls and messages, or simply keeping your personal life separate from your professional life.
To hide your number on WhatsApp, you need to enable the “Hide my phone number” setting in the app’s privacy settings. Once enabled, your phone number will be hidden from all new contacts you add, as well as from anyone who does not have your number saved in their address book. However, it’s important to note that this setting does not apply to existing contacts who already have your number saved.
