Q

Which of the following statements concerning MMSI is true?

🔍 Key Concepts

• Maritime Mobile Service Identity (MMSI) structure and what the 9 digits represent • The meaning and position of the Maritime Identification Digits (MID) in different types of MMSI (ship, group, coast) • Differences between ship station, group station, and coast station MMSI formats

💭 Think About

• For each option, ask: does this match the standard MMSI format defined for that specific type of station (ship, group, or coast)? • Think about where the MID is placed in the number for ship stations vs. coast stations: is it at the beginning, after leading zeros, or somewhere else? • Consider how group MMSI are distinguished from individual ship MMSI: what digit(s) usually indicate a group call?

✅ Before You Answer

• Verify that all MMSI are 9 digits long and that the MID is 3 digits within that structure • Check which MMSI type (ship, group, coast) typically begins with one or more leading zeros and where the MID appears in that pattern • Confirm whether coast station MMSI start with the MID first or whether they start with zeros before the MID
