What is Personally Identifiable Information (PII)? A short definition.

1 minute reading time

Personally identifiable information (PII) is any data that could potentially identify a specific individual. Any information that can be used to distinguish one person from another and can be used to deanonymize previously anonymous data is considered PII.

In addition to direct identifiers, such as passport information, which can be used alone or in conjunction with other relevant data, PII can also include quasi-identifiers, such as race, that can be combined with other quasi-identifiers, such as date of birth, to successfully identify an individual.
