Telegram, a popular messaging application, necessitates the provision of a valid mobile telephone identifier during the initial account registration process. This unique numerical sequence serves as the primary means of authentication and identification for each user within the Telegram ecosystem. A confirmation code is sent to the supplied number to verify ownership and complete the setup.
This method of user identification offers several advantages. It provides a relatively straightforward method for managing accounts and preventing the creation of numerous anonymous profiles. It also facilitates contact discovery, enabling users to easily find and connect with individuals within their existing network. Historically, this system has been implemented to combat spam and maintain a degree of accountability within the platform.
