The International Maritime Organization (IMO) number is one type of unique vessel identifier (UVI).
For a ship, the IMO number remains linked to the hull for its lifetime, regardless of changes in name, flag, or owner. IMO numbers help to improve maritime safety and security and reduce illegal fishing activities. IMO numbers are issued free of charge.
