What is NOT required to submit a person query (QW)?

To submit a person query (QW), certain basic identifying information is necessary to retrieve accurate data. Typically, the system requires a person's first name, last name, and often their date of birth to differentiate between individuals, especially when names may be common. These pieces of information help ensure that the query returns the correct results associated with that specific individual.

The social security number, while a valuable identifier in many contexts, is not mandatory for conducting a person query. This is likely due to privacy considerations and the varied contexts in which individuals might be searched, which wouldn't always include access to this sensitive information. Thus, the correct choice indicates that a social security number is not required to submit a person query.
