Where can the MMSI database be accessed?

• A. Via the Coast Guard MISLE system under vessel look-up
• B. Via the National Maritime Information Portal under ship search
• C. Via the International Telecommunication Union registry
• D. Through the Coast Guard's Vessel Tracking System

Answer: (A)

Access to the MMSI database is through the Coast Guard MISLE system, using the vessel look-up function. MISLE is the Coast Guard’s integrated data platform for vessel information and safety enforcement, and its vessel look-up lets authorized users search by MMSI to retrieve the vessel’s identifiers and related details. This path is the standard workflow for Coast Guard operations when you need to confirm or review a vessel’s MMSI-linked data. The other options aren’t the primary access points for the MMSI database in operational contexts. The National Maritime Information Portal’s ship search isn’t the designated MMSI lookup tool used in Coast Guard workflows. The International Telecommunication Union registry is the official source that assigns MMSIs, but it isn’t the day-to-day look-up system used for vessel data in USCG operations. The Vessel Tracking System focuses on live tracking and AIS data rather than querying the MMSI database itself.
