Hull Identification Number
The Hull Identification Number (HIN) is a unique, 12-digit number assigned by the manufacturer to vessels built after 1972.
Hull Identification Numbers:
- Distinguish one vessel from another.
- Are engraved in the fiberglass or on a metal plate permanently attached to the transom.
You should write down your HIN and put it in a place separate from your vessel in case warranty problems arise or your vessel is stolen.
All vessels used on the waters of Washington State must have an HIN. If your vessel has no HIN, you can apply for one at any vehicle/vessel licensing office. Visit www.dol.wa.gov for locations.
For information on how to display your HIN, refer to the document “Hull Identification Number (HIN) Display Instructions.”
