Which of the following is NOT commonly considered PII?

• A. Social Security Number
• B. IP address
• C. Email address
• D. Favorite color

Answer: (D)

PII is information that can identify a person or be used to contact or trace someone. A Social Security Number is a direct identifier that uniquely ties to an individual. An IP address can be used to identify a user or device, especially when combined with other data. An email address serves as a point of contact and can link back to a person’s identity. A favorite color, on the other hand, is simply a personal preference and does not identify a person on its own. Because it doesn’t reveal who someone is, it’s not commonly treated as PII.
