🔍 Key Concepts

• Maritime Mobile Service Identity (MMSI) structure and what the first three digits (MID or special prefixes) indicate • Special MMSI prefixes for coast stations, group calls, and SAR aircraft • How 003xxxxxx-type MMSIs are categorized in ITU/DSC addressing schemes

💭 Think About

• Look at the leading digits of 003669991. What does a leading '00' or '003' usually signify in MMSI assignments? • Which types of stations (ships, coast stations, or groups) share a common pattern in their MMSI numbers rather than a country MID? • Compare the given MMSI to examples you’ve seen in GMDSS or ITU materials for coast stations and group ship stations—what does it most closely resemble?

✅ Before You Answer

• Verify in your reference tables how coast station MMSIs are formatted (number of digits and starting pattern). • Verify how group ship station MMSIs are formatted and what digits they start with. • Confirm whether a Sea Area (A1–A4) or a specific trade (e.g., intercoastal) affects the MMSI numbering, or if MMSI is assigned by station type instead.
