VOI alerting can function on which identifiers?

• A. Name only
• B. MMSI only
• C. Either Name or MMSI
• D. Both Name and MMSI

Answer: (C)

VOI alerting is designed to identify targets using the identifiers you have available, and it supports both the vessel’s name and its MMSI. This flexibility is practical: you might know the ship by name from human notes or reports, or you might have the MMSI from AIS data. Using MMSI provides precise, unique identification, while using the name makes alerts usable in human-centered workflows where the numeric identifier isn’t on hand. The system should trigger as long as either identifier matches, which is why the best answer is that VOI alerting can function on either Name or MMSI. If only one identifier is available, you can still set up and rely on the alert. Names can be ambiguous across ships, but that doesn’t prevent alerts when the known identifier matches, and MMSI-only alerts work when you have the numeric ID.
