The end of phone numbers: A future without traditional communication identifiers

Maksudul, Shadat Akash (2025) The end of phone numbers: A future without traditional communication identifiers. World Journal of Advanced Engineering Technology and Sciences, 14 (1). 060-068. ISSN 2582-8266

The historical role of phone numbers as primary communication identifiers is undergoing a transformative shift, driven by technological advancements and evolving user demands. While phone numbers have traditionally facilitated personal and professional interactions, their limitations, including privacy vulnerabilities and declining utility in digital ecosystems, are increasingly apparent. Emerging alternatives such as unified digital identities, app-based communication platforms, and biometric authentication methods offer enhanced privacy, security, and user experience. Technologies like IoT, AI, and blockchain are further accelerating this transition by enabling seamless device interactions, personalized communication, and secure identity verification without reliance on static identifiers. However, the shift faces significant challenges, including infrastructure dependency, cultural resistance, and the need for cohesive regulatory frameworks. Despite these barriers, the decline of traditional phone numbers is anticipated by 2030, as digital identifiers gain prominence across industries, fostering global connectivity and inclusivity. This transition heralds a profound redefinition of societal communication practices, emphasizing innovation while ensuring equitable access to emerging technologies.
