🔍 Key Concepts

• MMSI (Maritime Mobile Service Identity) structure and what the first digit(s) indicate • Difference between an MMSI assigned to a single ship, a coast station, and a group of vessels • How a group call MMSI is formed from a normal ship MMSI

💭 Think About

• Look carefully at how many leading zeros each option has and what that usually signifies in MMSI numbers • Decide which type of station (ship, coast, or group) the question is asking about, and match that to the correct MMSI pattern • Ask yourself: for a group of vessels, should the MMSI look more like a ship MMSI or a coast station MMSI, and what small change is made to indicate a group?

✅ Before You Answer

• Verify which MMSI formats begin with 0, 00, or no leading zero and what each pattern represents • Confirm that a group call MMSI for ships has a specific starting digit pattern while still containing a valid MID (Maritime Identification Digit) in the usual position • Eliminate any option whose starting digits match a coast station MMSI rather than a group of vessels
