What is meant by "personally identifiable information" (PII)?

"Personally identifiable information" (PII) refers specifically to any data that can be used to identify an individual. This encompasses a wide range of information, including names, social security numbers, addresses, email addresses, phone numbers, and other identifiers that can pinpoint an individual either directly or indirectly. The definition is crucial in various contexts, particularly in data privacy and security, as it emphasizes the need to protect such information to prevent identity theft and ensure that individuals’ privacy rights are respected.

The importance of understanding PII lies in the responsibility that organizations have to safeguard it, as it can lead to serious consequences if mishandled. For instance, a data breach resulting in the exposure of PII can lead to identity theft and fraud. By recognizing what constitutes PII, businesses can implement appropriate measures to protect this sensitive information and comply with relevant regulations and best practices regarding data management.
