Abstract: The system allows for the allocation of email addresses to almost every possible person within a country, and allows for easy lookup and/or addressing of messages whether by email, telephone, mail or fax to those subscribers. It makes use of a combination of the subscriber's telephone number and an alphabetical component chosen from their name, for individuals, or an alphabetical description of a department within a business, together with a database server that stores information about each subscriber, and their preferred mode of delivery. The system requires users to create or modify their primary account by a telephone interface, as the system allows for delivery of email messages to subscribers by telephone, mail or fax, to those subscribers who do not have access to a computer and thus access to software to read their emails.
