Q

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

🔍 Key Concepts

• Maritime Mobile Service Identity (MMSI) structure for ship stations • How Maritime Identification Digits (MID) indicate a vessel’s flag state (country) • The specific MIDs assigned to the United States in ITU and FCC references

💭 Think About

• Look at the 9‑digit numbers and identify where the first three meaningful digits (the MID) appear for a ship station MMSI. • Recall which three‑digit codes are officially assigned to the United States and see which option’s pattern matches that. • Consider the difference between ship station IDs and other MMSI formats (like coast stations or group calls) and how that affects the leading digits.

✅ Before You Answer

• Verify which three‑digit MID blocks belong to the U.S. (e.g., 303, 338, 366–369 – confirm your list from your study material). • Check that the number follows the standard 9‑digit MMSI ship station format, not a coast or group identity format. • Confirm that the MID in your chosen option appears in the correct position in the 9‑digit MMSI for a ship station.
