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 on or near the upper starboard (right) side of the transom.

Owners of homemade vessels or vessels without a 12-digit HIN must apply for a hull identification number.

  • Submit an application for a Hull Identification Number for watercraft, including pictures of the vessel and the fee, to the SCDNR.
  • If requested by the SCDNR, schedule an appointment for a DNR officer to inspect the vessel prior to assigning the HIN.

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.
