Hull Identifications

Hull Identification

The United States requires all boats manufactured or imported in, have a permanently marked Hull identification number or HIN.

This number is used to identify each boat and can be located at the stern of the boat, most often on the starboard side of the transom. This number is used to register a boat and track its history.

What is a HIN number?

The HIN is a twelve-character identification made up of three letters, which indicate:

  • Manufacturer
  • Five-character serial number
  • Month and year of production
  • Year of production
