BoatWiki - Definitions
An IMO number can be defined as a unique identifying code assigned to certain sea-going vessels by the International Maritime Organization. Such numbers do not typically apply to smaller vessels, sailboats, and those used for recreational purposes. An IMO number is made of the three letters "IMO" followed by a seven-digit number. This consists of a six-digit sequential unique number followed by a check digit. The integrity of an IMO number can be verified using its check digit.
IMO numbers are instrumental in identifying a particular vessel as part of an international effort to improve maritime safety, security, fraud and pollution control.
The IMO numbers assigned to Coast Guard documented vessels are referenced on their certificate of documentation and shown on most detailed searches..
IMO numbers are generally of no significance to recreational boaters other than as a reference on certain vessel documentation records.
