Personal Identifiable Information (PII) refers to any information that can be used to identify a specific individual, such as name, address, date of birth, social security number, passport number, driver's license number, financial account numbers, email address, phone number, and biometric data.

PII can also include other types of sensitive information, such as an individual's race, religion, political affiliation, medical history, and sexual orientation.

PII is often collected by organizations and businesses for various purposes, such as conducting background checks, providing services, and conducting marketing campaigns. However, it is important to protect PII from unauthorized access, use, and disclosure to prevent identity theft, financial fraud, and other forms of harm.
