Which of the following numbers indicates a ship station MMSI?

• A. A. 003372694
• B. B. 030356328
• C. C. 3384672
• D. D. 623944326

Answer: (D)

To determine which number indicates a ship station MMSI (Maritime Mobile Service Identity), it is essential to understand the structure and format of MMSI numbers. An MMSI number is a unique nine-digit identifier assigned to a ship station or a coast station in maritime communications. The correct answer is a nine-digit number, as MMSIs are structured to be exactly that length. Option D, 623944326, fulfills this criterion as it contains nine digits. In contrast, the other choices either have fewer or insufficient digits. Options A, B, and C fall short because they either include leading zeros or only consist of fewer than nine digits, which disqualifies them from being valid MMSI numbers. This understanding of the specific length and format of MMSI numbers is critical for identifying the correct answer among the options provided.
