Hull Identification Number


BoatWiki - Definitions


A  boat hull identification number can be defined as an alphanumeric sequence which is permanently affixed or imprinted to an exterior part of a boat's hull in a manner set forth by federal regulations. Hull numbers are typically assigned by the manufacturer, but can also be designated under various circumstances by state agencies or the U.S. Coast Guard. A boat hull identification number is also known as a HIN, hull number, factory hull number, manufacturer hull number, or serial number.


Hull identification numbers are designed to provide every boat with its own unique means of identification. They identify the manufacturer and provide certain production information, including a serial or production number. This is similar to what you would find with vehicles in the automotive industry.


As of 1972, all boats built in or imported into the United States are required to have hull identification numbers that conform to a specific type of formatting. Although the length in characters remains consistent, there have been minor changes over time with respect to their exact configuration. Boat hull identification numbers are referred to in the marine industry under various terms as shown above. A hull number should not, however, be confused with an official Coast Guard vessel documentation number.


Getting the hull number right is one of the most important aspects of any boat transaction. Further information can be found by visiting the links in WikiTags and by perusing through other pages of BoatWiki.
