The most direct way is to use our online lookup tool, which allows you to complete a vessel official number search using identifying information tied to the boat.
Through our portal, you can enter a Hull Identification Number and retrieve the official number assigned by the U.S. Coast Guard, along with related federal documentation details, all in one place and without navigating multiple government systems.
What Is a Vessel Official Number and Why Does It Matter?
A vessel’s official number is a unique identifier issued by the U.S. Coast Guard to vessels that are federally documented. This number remains with the vessel for its lifetime and does not change with ownership transfers or renewals. Because of its permanence, the official number plays a central role in federal records and filings.
Understanding the purpose of an official number helps clarify why access to it is so important. It serves as the backbone for documentation records and connects all filings associated with the vessel.
Key points about an official number include:
- It is assigned once and remains permanently linked to the vessel
- This number differs from state registration numbers
- It is used in federal filings and records
- It connects documentation history over time
How Does Our Vessel Documentation Search Work?

The search process through our service can provide:

This broader view allows users to understand where the vessel stands in terms of documentation without conducting multiple searches.
Search results may include:
- Documentation status
- Issuance date of the Certificate of Documentation
