First instituted on November 1, 1972, Hull Identification Numbers, or HINs, are to boats what Vehicle Identification Numbers (VINs) are to automobiles. The code is an international identifier for each individual boat, and no two boats have the same HIN. Since HINs are federally mandated, all boat manufacturers assign these unique codes during production. The HIN is uniform, following the same format, regardless of the boat manufacturer. From 1972 to 1984, a 12-position code was used, and in 1984 the 12-digit system was slightly updated.
