VIN model year codes chart (position 10)

The 10th character of a VIN is the model year. It comes from a 30-year cycle of letters and digits, so each code stands for two years, 30 years apart. The letters I, O, Q, U and Z and the digit 0 are never used in this position.

Choosing the model year for a trailer

• The model year is the manufacturer’s designation for that model, not necessarily the calendar year it’s built in. Many trailer builders switch to the next model year in the late summer or fall.
• Pick one rule and stick to it, so trailers built on the same day for the same model have the same model year.
• The month and year actually built go on the compliance label separately, as the date of manufacture.
• Serial numbers usually restart for each model year, which is why the model year matters when you count up.

VINready suggests the model year for you and keeps a separate serial count for each one. To read the year from an existing VIN, use the trailer VIN checker.
