Which of the following statements concerning MMSI is true?

The correct answer, which states that none of the other answers are correct, implies that the provided options do not accurately reflect the specifications or standards regarding the Maritime Mobile Service Identity (MMSI).

In terms of MMSI assignment:

• Each ship station’s MMSI typically does not start with a single zero; ship stations usually have a unique identifier assigned by national authorities, which does not necessarily follow this pattern.

• Group station MMSIs, which are assigned to networks or groups of ships, may contain the Maritime Identification Digit (MID), but the stipulation that they must begin with the MID is misleading as different countries have specific formats for group stations.

• For Coast Stations, while it is true they have their own unique formatting rules, the assertion that they must start with the MID followed by two zeros is not universally applicable according to global standards.

Thus, the statement accurately reflects that the other options do not conform to the established rules and standards that govern MMSI assignments. This understanding is crucial for anyone involved in maritime operations to ensure compliance with communication protocols.
