Static user information such as address, title, phone number(s), email address(es) and dynamic user information such as location, calendar, current phone number(s), etc. are combined in a dynamically updateable subscriber contact card for publishing to other applications. The subscriber contact card also includes user defined access controls for restricting access to portions of the information by select users. Other applications provide services such as communication services based on up-to-date information through the subscriber contact card.
