In an era of rapid technological transformation and the expansion of social networks, human relationships and adolescent identity formation among Iranians are closely intertwined with urban and rural social environments. Adopting a phenomenological approach, this study analyzes the role of social media (Instagram and X) in redefining the language, literature, and identity of Iranian adolescents (ages 11 to 19). Quantitative data analysis and group interviews reveal that social networks not only serve as tools for intra-group and inter-group communication but also constitute platforms for lifestyle changes, the creation of new identities, and the reproduction of human relations in both urban and rural settings. Adolescents actively use these networks to expand their social connections, express personal emotions, and engage in multifaceted interactions—a process influenced by environmental (urban–rural), economic, and cultural factors. Alongside these communication opportunities, social media fosters the development of fluid identities among adolescents and introduces certain cultural and social challenges at both the individual and collective levels. The findings indicate that these networks are not merely virtual spaces, but new infrastructures for recreating local culture, managing lifestyles, and redefining traditional boundaries between urban and rural communities.
