Which of the following is considered least likely to be non-public personal information?

In the context of non-public personal information, the least likely choice to be considered sensitive is the employer's phone number. Non-public personal information typically refers to details that pertain specifically to an individual and their personal and financial status, which can include items like income, job title, and personal contact information.

Borrowers' home phone numbers, job titles, and income are all closely tied to their personal lives and financial situations, making them more sensitive and private in terms of confidentiality and data protection. On the other hand, an employer's phone number, while still potentially private, is generally considered a public contact detail that can often be found through various professional channels or directories. This distinction allows the employer's phone number to be viewed as less sensitive and less likely to be classified as non-public personal information.
