The National Directory Database “NDD” is a record of all subscribers of publicly available telephone numbers in the State, who have not refused to have their details recorded in it. It includes both home phone and mobile phone numbers.
The NDD has two functions:
• The primary purpose of the NDD is to hold the listing preferences of all consumers as to whether they wish to be listed for telephone directories and directory enquiry services purposes.
• It also holds consumers’ preferences as to whether or not they wish to be contacted by direct marketing companies. This is known as a direct marketing preference.
