A network system and methods utilized for tracking activities related to an event, such as audio communications, chats, text messages, completion of forms, and other user interactions. The method generates at least one identifier, distributes the identifier(s) to at least one system, and uses the identifier(s) to associate interactions with network-based content across different entities, whereby at least one interaction can be anonymous. The method involves receiving a request sent to a database stored on a computer readable medium in response to online activity and any collected or known user information, creating a record thereof in response to the request, generating an identifier associated therewith, generating a code corresponding thereto, and using the identifier to associate activities related to an event and user information. The association happens through remote communication with a system that interacts with the event.
