Which of the following is NOT considered personally identifiable information (PII) under most US state breach laws? a) Student identification number b) Social Security number c) Driver’s license number d) Credit card number

In the context of most US state breach laws, all the options listed (student identification number, Social Security number, driver’s license number, and credit card number) can be considered personally identifiable information (PII). However, it's worth noting that the classification of what constitutes PII may vary by state. Typically, a **student identification number** might be considered less sensitive than the other forms of identification listed, which are more commonly recognized as PII. Therefore, if one had to choose the option that is often considered less critical or less regulated than the others when it comes to breach notifications, it would likely be: **a) Student identification number.** Keep in mind that definitions and requirements can vary by state, so it’s always best to reference the specific laws applicable in each jurisdiction.
