Personal Identifiers (PID) are a subset of personally identifiable information (PII) data elements, which identify a unique individual and can permit another person to “assume” that individual's identity without their knowledge or consent.

This can occur when PID data elements are used in any of these ways:

  1. Alone
  2. Combined with a person's name
  3. Combined with other PID data elements
  4. Combined with other PII
