EVER WONDER WHAT THOSE NUMBERS REPRESENT

HINs By The Numbers

A typical hull identification number (HIN) consists of 12 letters and numbers, as in ABC12345D404.

Here's what the letters and numbers mean:

ABC: This is the U.S. Coast Guard-assigned manufacturer identification code (MIC). Go to the USCG Manufacturers Indentification page to access the Coast Guard's MIC database.

12345: This is the serial number assigned to the hull by the manufacturer. This may be a combination of letters and numbers. The letters "I," "O," and "Q" are excluded because they could be mistaken for numbers.

D: This is the month of certification, indicating the month in which construction began. "A" represents January and "L" represents December. In our example, "D" means April.

4: This is the year of certification. The number is the last digit of the year in which the boat was built. "4" in this case designates 2004.

04: This indicates the boat's model year.
