"Personally identifiable information" is information that can be matched with a person's identity, such as a user's address, personal interests, activities, spending habits, and significant relationships. Companies, governments, or other organizations often collect "personally identifiable information" in order to conduct business with individuals or households. For example, a business may be required to collect personally identifiable information - such as name, address, telephone number, credit card number - and a great variety of other information to be able to bill and provide service to the individual.
