Where do I look for the hull identification number?
The hull identification number (HIN) on all boats built after November 1, 1972 is permanently affixed to the rear of the transom usually on the upper right corner. It is required by federal law and must appear on the registration application.
The HIN consists of 12 letters and numerals at least one-quarter inch tall that indicate the manufacturer, hull serial numbers and/or letters, and model year and/or month.
