If you want to document a boat online, the National Documentation E-Portal provides an online way to complete the initial Coast Guard documentation application and submit supporting records electronically. Our portal brings the application process into one location, helping vessel owners enter required information, upload documents, and submit a filing without assembling a traditional paper package for mailing.

Start With the Initial Vessel Documentation Application
The first step is completing the initial Coast Guard vessel documentation application through our online portal. Entering the requested vessel and ownership information electronically provides a centralized way to prepare the filing before submission.
The initial application is available through our Initial Vessel Documentation service.
The application can include:
- Vessel name and official number
- Hull Identification Number
- Construction information
- Ownership information
- Vessel dimensions
- Requested endorsement information
Our online format lets owners document a boat online through a centralized filing process.
Enter Vessel and Ownership Information Carefully
Accurate information is an important part of a Coast Guard documentation filing, so the online application should be completed using information applicable to the vessel and its ownership record. The portal provides a digital format for entering that information as part of the submission process.
The application includes fields for the vessel and applicant. Enter information that corresponds with supporting records.
Depending on the filing, information may concern:
The digital application makes it possible to document a boat online without relying on a paper-only submission.
- Vessel name and hull information
- Previous documentation, when applicable
- Owner information
- Construction and measurement details
- Requested endorsement or trade indicator
Different documentation needs use different forms, so select the application matching the transaction.
Upload Supporting Documentation Through the Portal
Electronic document upload allows supporting records to be submitted as part of the online documentation process instead of requiring every item to be assembled into a conventional mailed package. Our portal includes a Document Upload function for information associated with Coast Guard documentation application processing.
Supporting paperwork may be submitted electronically when required. Our Document Upload service accepts relevant records associated with USCG documentation applications.
Uploaded records can include items such as:
- A USCG 1340 Bill of Sale
- A previous Certificate of Documentation
- A Last Will and Testament when applicable
- Other documentation associated with the application
Applicants are responsible for supplying records applicable to their transaction.
Review the Applicable Federal Documentation Rules
Federal vessel documentation requirements are established by Coast Guard regulations, while the National Documentation E-Portal provides an online filing service for submitting documentation applications. The applicable federal rules can be reviewed through the Electronic Code of Federal Regulations.
The federal regulations governing vessel documentation are contained in Title 46 of the Code of Federal Regulations. Owners can document a boat online while still following the applicable federal framework.
We provide the online filing environment rather than legal research or eligibility determinations.
Select the Correct Coast Guard Documentation Transaction
The National Documentation E-Portal offers separate applications for different Coast Guard documentation transactions. Selecting the form that corresponds with the transaction allows the filing to address the specific record or certificate action being requested.
Available documentation-related transactions include:
Our portal lets applicants document a boat online when the applicable transaction is initial documentation.
- Initial Vessel Documentation
- Renewal
- Transfer/Exchange
- Reinstatement of Documentation
- Change of Address
- Change of Vessel Name or Hailing Port
- Replacement of a Certificate of Documentation
- Certified Copy of Documentation
- Change of Endorsement/Trade Indicator
- Deletion from USCG Documentation
- Satisfaction and Release of Mortgage
- Preferred Ship Mortgage
- Notice of Claim of Lien
The portal also provides Document Upload and Vessel Documentation Search. For a first Certificate of Documentation, use Initial Vessel Documentation.
Submit the Completed Application Electronically
After the required application fields and supporting records have been entered or uploaded, the completed filing can be submitted through the online process provided by the National Documentation E-Portal. Electronic submission avoids preparing the entire application as a traditional paper package for mailing.
Complete the applicable digital form and provide its associated records. The electronic workflow lets you document a boat online through the portal.
Our portal uses secure technology and advanced SSL encryption for online transmission.
We do not promise a specific Coast Guard processing time or send status notifications after submission. The Coast Guard processes the filing.

Keep the Filing and Transaction Type Straight
A straightforward online filing depends on using the correct application and entering information that corresponds with the transaction being requested. Separating initial documentation from later changes or certificate transactions helps prevent confusion when using an online Coast Guard documentation portal.
An initial Certificate of Documentation is only one Coast Guard transaction. Existing vessels may require another application for ownership, address, name, hailing port, endorsement, or certificate changes.
Our portal lists the available forms so applicants can access the filing associated with their transaction. The same online environment provides access to:
- Vessel Documentation Search by Official Number and HIN
- Document Upload
- Certified Copy requests
- Mortgage-related filings
- Lien-related filings
- Deletion requests
This puts multiple Coast Guard forms in one location.
