Identifier dependent operation processing of packet based data communication is provided. A natural language processor component can parse an input audio signal to identify a request and a trigger keyword. A content selector component can select, based on the request or trigger keyword, a content item. A link generation component can determine whether the client computing device has an account or a record in a database associated with the service provider device. In the absence of the record or account, the link generation device generates and sends a virtual identifier to the service provider device with instructions to generate an account in the database using the virtual identifier. Once the account is created, the service provider device can communicate with the client computing device.
