Ships on the map now, by flag.

Flags and MMSIs

The first three digits of a ship's MMSI name her flag. The United States' are 303, 338 and 366 to 369, so a ship's number tells you she is here before her name does.

A ship that changes flag is given a new MMSI and keeps her IMO number for life; her page lists the other MMSIs her IMO number was heard under.

How this list is made

A ship is listed under the flag her MMSI names. While she is on the map she is listed first, longest first; after that come the ships heard in the last year, A to Z, each with when and where she was last heard.

Read MMSI, IMO and call signs.
