In order to use WhatsApp, users must provide their phone number, which is used to verify their account and ensure the security of the platform.

Once the number is verified, the user can begin using WhatsApp to communicate with their contacts. The use of a phone number as a unique identifier on WhatsApp has some benefits and drawbacks.
