PII stands for what?

• A. Publicly Identified Information
• B. Personal Interaction Information
• C. Personal Interest Information
• D. Personally Identifiable Information

Answer: (D)

PII stands for Personally Identifiable Information, which is data that can identify a specific person. This can be direct identifiers like a full name, Social Security number, or biometric data, or indirect identifiers that, when combined with other information, can reveal who someone is (such as a birth date with a ZIP code or an online account linked to a real person). The correct choice matches the standard privacy term used in laws and best practices.

The other options don’t fit this widely used term. Publicly Identified Information isn’t the recognized label for data that identifies individuals, and Personal Interaction Information or Personal Interest Information describe activities or preferences rather than identifiers. Understanding what counts as PII helps determine what protections are needed, including access controls, minimization, and secure handling.
