Decode a Vehicle's Model Year from Its VIN
The Short Answer: Look at the 10th Character
On any vehicle with a standardized 17-character Vehicle Identification Number (VIN), the model year is encoded in the 10th character. Count from the left. The character in that position is a letter or a number that maps to a specific model year. In the United States, the 17-character format has been required since the 1981 model year, so this method works for vehicles from roughly that point onward.
There are two qualifications. First, the year codes repeat on a 30-year cycle, so one character can point to two different years. The 7th character usually resolves this for passenger vehicles. Second, the VIN gives the model year, which is not always the year the vehicle was built. Both points are explained below.
Where to Find the VIN
The base of the windshield on the driver's side, readable from outside the car; The certification label on the driver's door jamb; The vehicle title and registration documents; Insurance cards and policy paperwork
Compare the VIN in at least two of these places if you can. A mismatch between the dashboard plate, the door label and the paperwork is worth investigating before you buy.
Model Year Codes for the 10th Character
The year position uses letters and the digits 1 through 9. The letters I, O, Q, U and Z and the digit 0 are not used, which avoids confusion with similar-looking characters. Each code covers two possible years, 30 years apart.
Code | Earlier cycle | Later cycle; A | 1980 | 2010; B | 1981 | 2011; C | 1982 | 2012; D | 1983 | 2013; E | 1984 | 2014; F | 1985 | 2015; G | 1986 | 2016; H | 1987 | 2017; J | 1988 | 2018; K | 1989 | 2019; L | 1990 | 2020; M | 1991 | 2021; N | 1992 | 2022; P | 1993 | 2023; R | 1994 | 2024; S | 1995 | 2025; T | 1996 | 2026; V | 1997 | 2027; W | 1998 | 2028; X | 1999 | 2029; Y | 2000 | 2030; 1 | 2001 | 2031; 2 | 2002 | 2032; 3 | 2003 | 2033; 4 | 2004 | 2034; 5 | 2005 | 2035; 6 | 2006 | 2036; 7 | 2007 | 2037; 8 | 2008 | 2038; 9 | 2009 | 2039
Telling the Two Cycles Apart
Because codes repeat, a 10th character of A could mean 1980 or 2010. US VIN rules address this for passenger cars, multipurpose passenger vehicles and trucks with a gross vehicle weight rating under 10,000 pounds. For these vehicles, check the 7th character:
7th character is a number: the model year falls in the earlier cycle (1980–2009); 7th character is a letter: the model year falls in the later cycle (2010–2039)
This rule does not cover heavier trucks, buses, trailers and some other vehicle types. For those, use context: the vehicle's design, condition, odometer reading and paperwork usually make the decade obvious. A decoder tool will also resolve it.
A Worked Example
The VIN below is illustrative and does not belong to a real vehicle. Characters are numbered by position so you can locate the 7th and 10th:
Position: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17; VIN: 1 H G C M 8 2 6 3 3 A 0 0 0 0 0 0
The 10th character is 3, which means 2003 or 2033. The 7th character is 2, a number, so the earlier cycle applies and the model year is 2003. If the 10th character were A and the 7th were a letter, the model year would be 2010.
Model Year Versus Build Date
The VIN encodes the model year, which is a manufacturer's product designation. It is not the date of manufacture. New models often go on sale before the calendar year that shares their number. A car built in the second half of one year is commonly sold as the next year's model.
For the actual build date, check the certification label on the driver's door jamb. It normally shows the month and year of manufacture. The difference can matter in several situations:
Ordering parts when a running change happened partway through a model year; Checking whether a recall applies, since some recalls cover specific production date ranges; Judging the age of rubber components such as tires and belts
Vehicles Built Before 1981
Before the 17-character standard, each manufacturer used its own VIN format. Lengths and character positions varied. The 10th-character method does not apply to these vehicles. Decoding older VINs requires manufacturer-specific references, such as factory documentation or a marque club.
Checking Your Result
A single misread character can change the decoded year, so it helps to cross-check:
Confirm the 17 characters were copied correctly. The letters I, O and Q never appear anywhere in a standard VIN, so a character that looks like one of them is actually 1 or 0. On North American vehicles, the 9th character is a check digit calculated from the other characters. Decoders use it to flag VINs that were mistyped or are invalid. Run the VIN through a decoder, such as the free one provided by the National Highway Traffic Safety Administration (NHTSA). It returns the model year along with the manufacturer, body and engine details where they are available. Compare the decoded year with the title and registration. A discrepancy is a reason to look more closely at the vehicle's history.
Limits of This Guide
This guide covers the general US 17-character VIN standard. It does not include manufacturer-specific details, such as how a particular brand codes plants or trims in other positions, or VIN conventions for markets outside North America. For those, use the manufacturer's own documentation or a decoder that supports the specific make.
