Yes, there is an official method for performing a boat number lookup. We provide access to the official search system so you can enter a Hull Identification Number (HIN) or an Official Number and retrieve verified information.

While ownership details are not available through this particular search, you can obtain ownership and encumbrance information through an Abstract of Title. Our portal exists to simplify the steps needed to access these records and support your needs related to Coast Guard documentation.
What Information Can an Official Search Provide?
An official boat number lookup delivers a substantial amount of vessel-related data pulled directly from USCG files. When someone enters a HIN or an Official Number into the system, the search returns core identifying information and the latest recorded details about the vessel’s documented status.
A typical search can reveal:
- Vessel name
- Hull Identification Number
- Official Number
- Vessel flag
- Tonnage data
- Dimensions
- Service details
- Issue date of its Certificate of Documentation
- Expiration date of its Certificate of Documentation
This tool is designed to provide accurate information about the vessel itself. It does not supply personal contact information regarding the vessel owner. That type of data is restricted, and the USCG maintains strict guidelines on releasing it, consistent with federal rules found in parts of the Code of Federal Regulations.
Our role is to make the process of accessing this official search easier by providing a streamlined online portal so you can reach the correct Coast Guard resources without delays.

How Does a HIN Work for a Search?
A HIN functions as the vessel’s unique identifier. Similar to how a VIN uniquely identifies a vehicle, a HIN distinguishes one vessel from every other.
Since 1972, federally regulated vessels have been required to carry a standardized HIN format. When you conduct a boat number lookup using a HIN, the system cross-references this identifier with USCG records to identify active documentation status, historical information, and vessel attributes.
Our portal simply supplies the direct path to perform this lookup. Entering the HIN into the official system will allow you to view the details currently held in federal documentation files.
How Does an Official Number Work for a Search?
An Official Number is assigned to a vessel once it has been successfully documented with the Coast Guard. This number is permanent and remains with the vessel throughout its lifetime, even if the vessel is sold or renamed.
When performing a boat number lookup using the Official Number, you may see information that is not available through other search methods, because this identifier is tied directly to the vessel’s complete documented history.
Our portal allows you to access the page where this search can be performed, helping you reach the official federal records without having to navigate multiple government pages.
Why Can’t Ownership Information Be Accessed Through the Search?
The public search tool focuses on vessel-specific data rather than owner-specific details. Ownership details are restricted to protect privacy and comply with federal regulations. Because of that, a standard boat number lookup will not show:
- Owner names
- Ownership addresses
- Ownership history
- Mortgage holder details
However, there is a separate process for retrieving this type of information. An Abstract of Title provides ownership information, as well as any encumbrances that may be tied to the vessel.
These encumbrances may include items such as a preferred ship mortgage or recorded liens. If you need this level of detail, our portal links you to the correct form so you can request an Abstract of Title directly.
What Is an Abstract of Title and What Does It Show?
An Abstract of Title is the only official document that provides a vessel’s ownership history, recorded mortgages, and any active liens. This document is useful when evaluating whether a vessel is free of encumbrances or when reviewing the chain of title for legal or financial purposes.
Through the request form available on our site, users may apply for an Abstract of Title, which may include:
- Current owner of record
- Previous owners
- Dates of ownership transfers
- Any active preferred ship mortgage
- Released mortgages
- Notices of claim of lien
- Satisfaction filings
Our role is not to interpret, analyze, or investigate the information. Instead, we provide a convenient online method for users to request the record directly from the USCG.

How Does This Search Relate to Vessel Documentation?
The information returned in an official lookup directly connects to vessel documentation files maintained by the Coast Guard. A documented vessel carries an active Certificate of Documentation, and the search tool displays information drawn from those records. When a vessel undergoes documentation filing or USCG documentation renewal, its updated status will appear in subsequent searches once processed by the USCG.
Our service provides access to the forms used to manage these filings, including documentation renewal and related submissions, so you can keep your vessel’s federal paperwork current and consistent with the information you may see during a search.
Can This Search Help When Preparing Other Filings?
Yes, the information you retrieve can be useful when completing certain filings available on our portal. Although our service does not review information or check it for accuracy, having verified vessel details helps you ensure your forms are filled out correctly.
For example, you may find it helpful when preparing:
- A vessel change of address
- A documented vessel renewal
- A reinstatement request
- Replacement documentation for a lost Certificate of Documentation
- An application for an Abstract of Title
By entering accurate identifiers such as the HIN or Official Number into these forms, you reduce the likelihood of processing delays.
How Many Times Can a Boat Number Lookup Be Performed?
There is no limit to how often someone may use the search system. Because this is a publicly available Coast Guard resource, individuals may run the search as many times as needed. Our portal simply directs you to the page where these searches can be completed.
The availability of this search makes it simple to confirm vessel information before preparing a form or submitting a request.

What Are Some Common Reasons People Perform a Lookup?
People use the lookup tool for many purposes. While we do not determine how someone should use the information, we do provide the means to access the search. Some of the typical reasons individuals perform a search include:
- Confirming whether a vessel is currently documented
- Checking a vessel’s name or identifying markers
- Verifying a vessel’s dimensions
- Reviewing tonnage when preparing related filings
- Ensuring documentation details match the vessel records they already have
- Preparing to request an Abstract of Title
- Reviewing HIN or Official Number accuracy before filing federal documentation forms
If you need to update or file documentation after conducting your search, our portal provides access to the appropriate Coast Guard forms.
How Does This Search Support Those Filing Documentation Through Our Portal?
Our portal makes Coast Guard documentation submissions easier by providing digital access to official forms. The boat number lookup helps people verify details before submitting those documents, ensuring the identifiers they use align with the vessel’s official Coast Guard records.
While our service does not review the information, the lookup ensures you are pulling directly from federally recorded data.
How Many Times Should Someone Perform a Lookup Before Filing?
There is no specific requirement for how often you should run a search. Some individuals choose to check information immediately before completing their forms, while others run a search when preparing vessel documentation months earlier. Because the search is publicly accessible, you may perform it at your convenience.
Our portal provides the filing forms, but the Coast Guard maintains and updates the data that appears in the search. If the vessel undergoes documentation changes, renewals, or updates, new information may eventually appear in the records after USCG processing.
Does the Lookup Cover Every Vessel?
The search covers vessels that are documented with the U.S. Coast Guard. Recreational vessels that are state-registered rather than federally documented may not appear in the results. This tool is designed solely for vessels that fall within the Coast Guard’s documentation system.
If you are preparing documentation for a vessel that is or will soon be documented with the USCG, the lookup can help confirm the details associated with that vessel.
