How Do You Get a HIN Number for a Boat?

AvatarByFrancis Mortimer Boats & Vessels

If you own a boat or are planning to purchase one, understanding the importance of a Hull Identification Number (HIN) is essential. Much like a vehicle’s VIN, the HIN serves as a unique identifier for your vessel, playing a crucial role in registration, safety, and theft prevention. Whether you’re a first-time boat owner or a seasoned mariner, knowing how to obtain and properly use a HIN can save you time and hassle down the line.

Navigating the process of getting a HIN involves understanding the regulations set by authorities and the steps required to ensure your boat is legally recognized. This identification not only helps in tracking ownership but also assists in recalls and insurance claims, making it a vital part of responsible boat ownership. While the concept may seem straightforward, the procedures and requirements can vary depending on your location and the type of boat you have.

In the following sections, we will explore what a HIN is, why it matters, and the practical steps you need to take to get one for your boat. Whether you’re registering a new vessel or need to assign a HIN to an older, unmarked boat, this guide will provide the foundational knowledge to help you navigate the process with confidence.

Understanding the Structure of a Hull Identification Number (HIN)

A Hull Identification Number (HIN) is a unique 12-character serial number assigned to a boat by the manufacturer or, if necessary, by the boat owner through the appropriate authority. The HIN serves as the boat’s fingerprint, used to track its history, ownership, and compliance with safety standards. Understanding the composition of the HIN helps in both obtaining and verifying it.

The HIN is typically structured as follows:

  • Manufacturer Identification Code (MIC): The first three characters represent the manufacturer’s unique code assigned by the U.S. Coast Guard.
  • Serial Number: Characters four through eight are the boat’s serial number, assigned by the manufacturer.
  • Date of Certification or Manufacture: Characters nine through twelve provide information about the month and year the boat was certified or manufactured.
HIN Segment Position Description Example
Manufacturer Identification Code (MIC) 1-3 Unique code assigned to the boat manufacturer ABC
Serial Number 4-8 Manufacturer-assigned unique serial number 12345
Date of Certification/Manufacture 9-12 Month and year of manufacture or certification 12A9 (December 2019)

This standardized format helps ensure uniformity across all boats manufactured in or imported into the United States, aiding law enforcement, owners, and manufacturers alike.

Steps to Obtain a HIN for Your Boat

If your boat does not have a HIN or it needs to be replaced, the process to obtain one varies depending on whether the boat is newly manufactured, imported, or previously uncertified.

For newly manufactured boats, the manufacturer is responsible for assigning the HIN during the production process. However, for older or homemade boats, or boats imported without a HIN, the owner must apply through their state’s boating authority or the U.S. Coast Guard.

Key steps include:

  • Contact Your State Boating Agency: Most states have a dedicated office that handles HIN applications. This office will provide the required forms and instructions.
  • Complete the Application: The application will typically require details such as the boat’s make, model, year, dimensions, hull material, and any existing serial numbers.
  • Schedule an Inspection: Many states require a physical inspection of the boat to verify its dimensions and condition before issuing a HIN.
  • Submit Documentation: This may include a bill of sale, proof of ownership, photos of the boat, and any prior registration or documentation.
  • Pay Applicable Fees: Fees vary by state and may cover the inspection, application processing, and issuance of the HIN.

Important Considerations When Applying for a HIN

Obtaining a HIN is a critical step for registering and legally operating your boat. Keep the following points in mind:

  • HINs Are Non-Transferable: Once assigned, the HIN stays with the hull for its lifetime. It cannot be transferred to a different boat.
  • Ensure Accuracy: The information submitted during the application must be accurate to avoid delays or denial.
  • Inspection Requirements: Some states may waive inspections if the boat was previously registered or the ownership history is well documented.
  • Timing: Allow sufficient processing time; obtaining a HIN can take several weeks depending on the agency’s workload.
  • Record Keeping: Keep copies of all documents submitted and received for future reference.

Resources for Manufacturer Identification Codes and Application Forms

To facilitate the HIN application, it is essential to use the correct Manufacturer Identification Code (MIC) if you are the manufacturer or builder of the boat. The U.S. Coast Guard maintains a public database of MICs that can be searched online.

For convenience, here are some common resources:

  • U.S. Coast Guard MIC Database: Search for manufacturer codes by name or location.
  • State Boating Agency Websites: Download HIN application forms and find local contact information.
  • Boating Safety Organizations: Provide guidance and assistance during the application process.

Each state may have specific forms or additional requirements, so it’s advisable to check the official website of the state where the boat will be registered.

Understanding the Hull Identification Number (HIN)

The Hull Identification Number (HIN) is a unique 12-character serial number assigned to boats in the United States. It serves as the vessel’s fingerprint, providing essential information about its manufacturer, model year, and production details. The HIN is crucial for registration, titling, theft recovery, and insurance purposes.

Key features of the HIN include:

  • Manufacturer Identification: The first three characters identify the manufacturer.
  • Serial Number: Characters four through eight represent the vessel’s unique serial number.
  • Date of Certification or Manufacture: Characters nine through twelve indicate the model year and month of production.

The HIN must be permanently affixed to the boat’s hull, typically on the starboard side near the transom, ensuring visibility and durability.

Steps to Obtain a HIN for a Boat

Acquiring a HIN depends on whether the boat is newly manufactured, imported, or previously unnumbered. The process involves the following steps:

  • Determine Eligibility: Verify if the boat currently lacks a valid HIN. New boats from registered manufacturers usually have a HIN assigned before sale.
  • Contact the Manufacturer: For newly built boats or boats purchased from manufacturers, request the HIN directly if it was not provided.
  • Apply Through the U.S. Coast Guard (USCG): For vessels without a HIN, including imported boats or older vessels, submit an application to the USCG for assignment.

Applying for a HIN Through the U.S. Coast Guard

The USCG is the authoritative body responsible for issuing HINs to boats that do not have one. The application process involves:

Step Description Notes
1. Complete Form CG-1280 Fill out the Application for Assignment of Hull Identification Number. Available on the USCG National Vessel Documentation Center (NVDC) website.
2. Provide Documentation Submit proof of ownership such as a bill of sale, previous title, or registration. Essential to verify legal ownership before assigning a HIN.
3. Submit Photographs Include clear photos of the entire vessel and the area where the HIN will be affixed. Helps the USCG confirm the vessel’s identity and condition.
4. Pay the Fee Include the applicable processing fee with your application. Check current fee schedules on the USCG NVDC website.
5. Mail the Application Package Send all completed documents and payment to the USCG National Vessel Documentation Center. Use certified mail or another trackable method for security.

Upon approval, the USCG will assign a HIN and notify the applicant. The assigned number must then be permanently affixed to the vessel’s hull according to USCG specifications.

Guidelines for Affixing the HIN to a Boat

Proper placement and permanence of the HIN are mandated by federal regulations to ensure identification reliability. The guidelines include:

  • Location: Affix the HIN on the starboard side of the transom or hull within 12 inches of the top of the hull.
  • Material: Use corrosion-resistant metal or durable plastic plates with the HIN stamped or engraved.
  • Attachment Method: Secure the plate with screws, rivets, or weld it to the hull to prevent removal or tampering.
  • Visibility: The HIN must be easily visible and legible without disassembly of the boat.
  • Additional Markings: Some states may require duplicate HIN markings on other parts of the boat, such as the engine or trailer.

Compliance with these standards is critical to avoid penalties and to ensure proper registration and identification.

State-Level Procedures and Registration

While the HIN is a federal requirement, the registration and titling of the boat, which reference the HIN, are managed at the state level. Steps include:

  • Submit the assigned HIN along with ownership documents to the state’s boating agency or Department of Motor Vehicles (DMV).
  • Complete state-specific registration forms and pay applicable fees.
  • Display state registration numbers on the boat as required by local regulations.
  • Renew registration periodically according to state guidelines.

Because procedures vary by state, consult the relevant state agency’s website or office for precise instructions related to your jurisdiction.

Common Issues and Troubleshooting When Obtaining a HIN
