Q

Which of the following numbers indicates a U.S. flag ship station?

🔍 Key Concepts

• Maritime Mobile Service Identity (MMSI) format for U.S. ship stations • How the first digits of an MMSI indicate the country or type of station • Difference between U.S. flag ship, coast, and other special-purpose station IDs

💭 Think About

• Look at the first three digits of each number. What do those digits represent in the MMSI system? • Which of these first-three-digit groups is assigned to U.S. ship stations, not to shore, group, or special services? • Eliminate any option whose leading digits you know are used for non-U.S. or non-ship stations.

✅ Before You Answer

• Verify which MID (Maritime Identification Digits) blocks correspond to the United States in current ITU/MMSI tables. • Confirm that U.S. ship station MMSIs use the MID directly as the first three digits, not padded with leading zeros or special patterns. • Check that the remaining choice is a 9-digit number with a valid U.S. ship-station MID at the start.
