In terms of the Privacy and Electronic Communications (EC Directive) Regulations 2003, "PECR", the subscriber is the individual or legal entity that is party to a contract with a provider of public electronic communications services. It specifically defines a corporate subscriber as, essentially, an incorporated company. This is different to the usual meaning of “subscriber” when discussing mailing lists. The UK's data protection supervisory authority, the Information Commissioner's Office (ICO) has published guidance clarifying that this includes public bodies and Scottish partnerships, but not sole traders or members of an ordinary partnership, as they are not incorporated. In terms of email, the subscriber is held to be the individual or organisation for whom the email service is operated. Any of a corporate subscriber's email addresses would be a corporate email address. If a corporate email address contains a person's name or distinctive job title, it is known as a personal corporate email address. This is not the same as a strictly personal email address pertaining only to a private individual.
