Which items are primarily classified as personal identifiers?

Items classified as personal identifiers are those that can directly identify an individual and are often used for verification of identity. Driver's license numbers and addresses uniquely point to an individual, making them primary examples of personal identifiers. These items are typically used in various forms of identification and official records, which is why they are considered essential for personal identification purposes.

On the other hand, while PINs and passwords are crucial for protecting access to accounts, they are not typically used to identify individuals in databases or official records. Similarly, emails and social media accounts are more about online presence and may not reliably or solely identify an individual in official contexts. Bank account numbers and credit card numbers, while sensitive, primarily serve financial functions and can change or be shared among individuals, thus not being as definitive as driver’s licenses and addresses for personal identification.
