What is PII (Personally Identifiable Information)?
What is PII?
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.
Colorado law requires certain persons and entities to take reasonable steps to protect PII. The law requires notification of security breaches affecting personal information (PI), which includes detailed notice to Colorado residents and, in certain circumstances, notice to the Attorney General.
If you maintain PII, in paper or electronic form, you are required to develop a written policy to ensure that the PII is destroyed or properly disposed of when it is no longer needed.
Examples of PII:
- Full name
- Individual's maiden name
- Mother’s maiden name

- Social security number
- Passport number
- Driver’s license number
- Taxpayer identification number
- Financial account/Bank Account numbers
