PII is any piece of information or combination of information that can be used to identify a particular individual with a reasonable amount of certainty.
- A Social Security number on its own is PII.
- An age, gender, and location combination may or may not be PII, depending on the age and size of
the geographic area. “A 35-year-old man in Boston, MA” is not PII, but “A woman in her 90s in
Tanana, AK” is PII.
