That is, provided it stays on the same national register. And since the early 1980s, the IMO number became a lifetime indicator, regardless of flag, name etc. But there are some countries that don't have a national numbering system. For example, in Greece, the numbers are issued by ports, so will change if the port of registry changes (but stay the same if it is a new name at the same port). And of course the systems of national official numbers were only introduced in different countries during at varying times from the mid-19th century onwards. David
