What is Mrs. Smith's subscriber number if Mr. Smith's subscriber number is 001?

In many health insurance systems, subscriber numbers are unique identifiers assigned to individuals under a family or group policy. Often, these numbers are constructed in a way that follows a sequential or predetermined pattern. Given that Mr. Smith's subscriber number is 001, Mrs. Smith's number would typically follow in sequence to provide identification that is both unique and easily traceable.

The answer provided, which is 002, suggests that it is the next sequential number after 001, aligning with standard practices where family members are assigned numbers in ascending order. This system not only helps in easily identifying individuals within the same household but also ensures that each person has a distinct identifier for billing, claims processing, and other administrative purposes related to their health insurance.

Therefore, Mrs. Smith's subscriber number being 002 is logical and consistent with the identification protocols used in insurance to differentiate between family members while maintaining an organized system of records.
