Who maintains the MMSI databases?

• A. Operations Systems Center - Martinsburg, WV
• B. Federal Communications Commission - Watch Officer
• C. International Telecommunication Union - Publication
• D. National Oceanic and Atmospheric Administration - Office

Answer: (A)

MMSI databases are maintained by the Operations Systems Center in Martinsburg, West Virginia. This U.S. Coast Guard unit runs the national MMSI registry, assigns MMSI numbers to vessels, shore stations, and groups, and keeps the data up to date for AIS and other maritime communications. They work with ITU for international allocations, but the day-to-day maintenance is their responsibility. The FCC Watch Officer handles radio licensing and regulation, not the MMSI registry. The International Telecommunication Union provides international standards and allocations, not the U.S. database maintenance. NOAA handles weather, ocean, and navigation data, not MMSI numbers.
