All Recipient Portal's functions are assigned to a delivery stop's _____________, not its __________.

• A. Stop ID, Address
• B. Address, Stop ID
• C. Stop ID, Route
• D. Route, Address

Answer: (A)

The key idea is using a stable, unique identifier for each stop: the Stop ID. All Recipient Portal functions are tied to this exact identifier so they consistently apply to the correct stop, even if the location’s address changes, or if there are multiple stops at the same address. Addresses are human-readable and can be altered, reformatted, or duplicated across stops, which would create ambiguity and misassociation if used as the primary key. The Stop ID remains constant for that stop across routes and updates, ensuring reliable mapping of tasks, notes, and statuses to the right stop. A Route groups stops in a sequence, but it’s not the key that determines per-stop functions.
