The official number relates only the ship's flag of registry. It is not unique. Should a vessel change registry, e.g. from U.K. to Panama, the official number will change.
The IMO number is what used to be known as the "Lloyds Number". This is a unique 7-digit identifier which remains with a ship no matter how many times it changes name, flag, owner etc. It was adopted by the International Maritime Organisation (IMO) as a means of making ship identification easier. Since July 2005, it is compulsory for ships to display the IMO number on a prominent part of the ship. |
