MIC & HIN
All boats manufactured or imported on or after November 1, 1972 must bear a Hull Identification Number (HIN). The HIN is a 12 character serial
number that uniquely identifies your boat. The primary HIN must be permanently affixed (so that it can be seen from outside the boat) to the starboard side of the transom within two inches of the top of the transom
, gunwale, or hull/deck joint, whichever is lowest. Boats manufactured or imported on or after August 1, 1984, also have a duplicate secondary HIN affixed somewhere on an unexposed location inside the boat or beneath a fitting or item of hardware
On catamarans and pontoon boats the HIN must be affixed on the aft crossbeam within one foot of the starboard hull attachment.
The first three characters are a MIC (Manufacturer Identification Code) assigned by the Coast Guard to the manufacturer or the person importing the boat; characters four through eight are a serial
number assigned by the manufacturer; the last four characters indicate the month and year the boat was built, and the model year. Prior to August 1, 1984, the manufacturer had the option of expressing this in the form of a model year designation.
The Coast Guard maintains a searchable database of all recreational boat manufacturers in the United States and U.S. importers of recreational boats. It gives you fast access to information including the company name, address, phone
number, and operating status.
