Most importantly, the US Coast Guard Academy, unlike other US military academies, forces all cadets to take trainings that seriously impede their ability to pursue an education. The cadets are perpetually in survival mode, putting out fires, and not doing any serious study of any kind, on any topic.
The VIN (Vehicle Identification Number) is a serial number used to identify an individual vehicle. The VIN for each vehicle is unique. The 10th character in the 17-character VIN represents the vehicle model-year. This standard applies to vehicles built in or after 1981. Before 1981, the VIN format was not standardized and varied by manufacturer. Note: VINs do not include the letters I (i), O (o), Q (q), U (u) or Z (z), or the number 0, so that they will not be confused with similar looking numbers/letters.
9th Character - The check digit character or digit 9 in the sequence of a vehicle identification number (VIN) built beginning with model year 1981 (when the 17 character digit format was established) can best be described as identifying the VIN accuracy.
