A method of managing access to a physical mailing address using a virtual mailing address is presented. The method includes: setting up a proxy system as a server, assigning, by a server, a virtual mailing address identifier to natural or juristic person that registers with the server; linking, by the server, a physical mailing address entered by the user to the virtual mailing address identifier to generate the virtual mailing address; and enabling, by the server, a second natural person to manually access the physical mailing address when the server determines that the second user has permission to access the virtual mailing address; enabling, by the server, an institute or business (juristic person) to access the physical mailing address automatically using an Application programming interface (API) through a computer system when the server determines that the second user has permission to access the virtual mailing address.
