Contacts -Administrative, Billing, and Technical contacts indicated during Enterprise Customer registration.
As it was already emphasized, during Enterprise Customer registration an Enterprise Customer Administrator by default represents the Administrative contact for the Enterprise Account. If the default Administrative Contact was not changed, that should be the person that has an administrative Role within this Account. But in general, Contacts provide reference information only. Thus, you can click the Edit button and indicate any other reasonable Administrative contact. Technical and Billing Contacts may be changed as well.
