Q

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

🔍 Key Concepts

• MMSI (Maritime Mobile Service Identity) numbers and their 9‑digit structure • The role of the first three digits as Maritime Identification Digits (MID) for a country • Typical U.S. MID ranges (what numbers U.S. ship stations usually start with)

💭 Think About

• Look at the first three digits of each option and ask which set matches U.S. country codes used in MMSIs • Consider which option looks like a ship station MMSI, not a coast station or special-purpose number • Think about whether a leading zero in an MMSI usually indicates a different type of station than a normal ship station

✅ Before You Answer

• Identify which answer choice has first three digits that match a known U.S. MID range (e.g., in the 3xx series used by the U.S.) • Check that the MMSI is 9 digits and formatted like a normal ship station number (no extra pattern like 00 or 99 blocks typical of other services) • Eliminate any options whose first three digits clearly belong to non‑U.S. MIDs (assigned to other countries/regions)
