The IMO ship identification number scheme was
introduced in 1987 through adoption of resolution A.600(15), as a measure
aimed at enhancing "maritime safety, and pollution prevention and to
facilitate the prevention of maritime fraud" The IMO ship identification
number is made of the three letters "IMO" followed by the seven-digit number
assigned to all ships by the Lloyd's Register Fairplay when constructed.
This is a unique seven digit number that is assigned to propelled, sea-going
merchant ships of 100 GT and above upon keel laying with the exception of
the following:
.Vessels solely engaged in fishing
.Ships without mechanical means of propulsion
.Pleasure yachts
.Ships engaged on special service (e.g. lightships, SAR vessels)
.Hopper barges
.Hydrofoils, air cushion vehicles
.Floating docks and structures classified in a similar manner
.Ships of war and troopships
.Wooden ships
This number is assigned to the total portion of the hull enclosing the
machinery space and is the determining factor should additional sections be
added. The IMO number is never reassigned to another vessel and is shown on
the
ship's certificates.

Lloyd's Register - Fairplay is the sole authority for identifying and
assigning an IMO number.

Company and registered owner identification number
In May 2005, IMO adopted a new SOLAS regulation XI-1/3-1 Company and
registered owner identification number and amendments to regulation XI-1/5
on the mandatory company and registered owner identification number, with
entry into force expected to be on 1 January 2009.

Regulation 3-1 states that "every Company and registered owner shall be
provided with an identification number which conforms to the IMO Unique
Company and Registered Owner Identification Number Scheme adopted by the
Organization."

For new companies and registered owners, the assignment of the IMO unique
company and registered owner identification number should be made when the
company's ship is entitled to fly its flag. For existing companies and
registered owners, the assignment of the IMO unique company and registered
owner identification number should be made at an early convenient date,
such
as when the certificates listed in this resolution are issued or renewed.
