A unique identifier—also sometimes called a unique vessel identifier—is like a number plate for your vessel.
Domestic commercial vessels must have and display a unique identifier unless they are exempt.
A unique identifier is a number that stays with the vessel for its entire life, even if the vessel changes ownership. Unique identifiers help to identify domestic commercial vessels.
A vessel may need to be identified:
- For search and rescue purposes.
- If it has been lost or stolen.
- If it is being operated dangerously or illegally.
- If it is being surveyed.
Some vessels are exempt from the requirement to have a unique identifier, or from displaying it or both.
