Editing Vehicle identification number (section)

===Vehicle identifier section===
The 10th to 17th positions are used as the vehicle identifier section or VIS. This is used by the manufacturer to identify the individual vehicle in question. This may include information on options installed or engine and transmission choices, but often is a simple sequential number.

====Model year encoding====
The North American implementation of the VIS uses the 10th digit to encode the [[model year]] of the vehicle. Besides the three letters that are not allowed in the VIN itself (I, O and Q), the letters U and Z and the digit 0 are not used for the model year code. Outside of North America the 10th digit is usually 0.

The year 1980 was encoded by some manufacturers, especially General Motors and [[Chrysler]], as "A" (since the 17-digit VIN was not mandatory until 1981, and the "A" or zero was in the manufacturer's pre-1981 placement in the VIN), yet [[Ford Motor Company|Ford]] and [[American Motors Corporation|AMC]] still used a zero for 1980. Subsequent years increment through the allowed letters, so that "Y" represents the year 2000. 2001 to 2009 are encoded as the digits 1 to 9, and subsequent years are encoded as "A", "B", "C", etc.

On April 30, 2008, the US [[National Highway Traffic Safety Administration]] adopted a final rule amending 49 CFR Part 565, "so that the current 17 character vehicle identification number (VIN) system, which has been in place for almost 30 years, can continue in use for at least another 30 years", in the process making several changes to the VIN requirements applicable to all motor vehicles manufactured for sale in the United States. There were three notable changes to the VIN structure that affect VIN deciphering systems:
* The make may only be identified after looking at positions one through three and another position, as determined by the manufacturer in the second section or fourth to eighth segment of the VIN.
* In order to identify the exact year in passenger cars and multipurpose passenger vehicles with a GVWR of 10,000 or less, one must read position 7 as well as position 10. For passenger cars, and for multipurpose passenger vehicles and trucks with a gross vehicle weight rating of {{convert|10000|lb|abbr=on}} or less, if position seven is numeric, the model year in position 10 of the VIN refers to a year in the range 1980–2009.<ref>{{cite web |url=https://www.law.cornell.edu/cfr/text/49/565.15 |title=49 CFR § 565.15 – Content requirements |work=[[Legal Information Institute]] |publisher=Cornell University |location=US |access-date=2021-06-04}}</ref>{{Citation needed|reason=Seems wrong as e.g. a 2013 Volvo V60 has YV1xxx7xxDxxxxxxx|date=May 2017}} If position seven is alphabetic, the model year in position 10 of VIN refers to a year in the range 2010–2039.
* The model year for vehicles with a GVWR greater than {{convert|10000|lb|abbr=on}}, as well as buses, motorcycles, trailers and low-speed vehicles, may no longer be identified within a 30-year range. VIN characters 1–8 and 10 that were assigned from 1980 to 2009 can be repeated beginning with the 2010 model year.

====Plant code====
Compulsory in North America and China is the use of the 11th character to identify the assembly plant at which the vehicle was built. Each manufacturer has its own set of plant codes.

====Production number====
In the United States and China, the 12th to 17th digits are the vehicle's serial or production number. This is unique to each vehicle, and every manufacturer uses its own sequence.
