A unique electronic communications account is generated and linked to a physical address of a user. A network of electronic mail addresses linked to physical addresses can be used for the transmission of information in electronic or physical form. Users can send information to a single recipient or multiple recipients by selecting the recipient or an area of recipients on a map generated by the system. A plurality of users can use a single e-mail address linked to a physical address through creation and storage of user profiles. Users can deactivate and transfer their unique electronic mail address upon relocation to a new physical address. The communication platform can overcome technical problems and limitations of electronic mail existing today. The communication platform can create a transparent global communication that can be achieved via an electronic communications account that can be created for every physical address in the world.
