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.

If the HIN is missing or non-existent, such as with a homemade vessel, apply for an identification number from the DMV.

  • If the vessel does not need a title or is valued at less than $1,000, a number will be assigned and mailed to you. You will attach it to the vessel.
  • If the vessel requires a title or is valued at $1,000 or more, a DMV Inspector will attach the HIN.
