Why is Vehicle Identification Number written in capital letters? Michael Hardy 22:53, 15 Mar 2004 (UTC)
Probably to emphasize the initials / acronym. I don't believe this is compulsory. Nessalc 05:29, Feb 6, 2005 (UTC)
It's a proper title and a legal term in the US.--TGC55 23:57, 29 March 2006 (UTC)

[edit] Source of NA standard?
At this writing, the article states, "In North America, a more stringent (but compatible) system is used." What exactly is this system and who defines it? —LarryGilbert 00:04, 2004 Dec 28 (UTC)
- The Society of Automotive Engineers oversees the NA standard: SAE VIN page --SFoskett 16:29, Dec 28, 2004 (UTC)

- No, the SAE only administers the WMI portion of the USA VIN on behalf of the US government's NTHSA. The reason why the VIN is used in the USA is down to US federal Regulation 49CFR565. I have no idea why it was written that the USA VIN system is "more stringent" than any other, as I had thought all 17-digit VIN systems used a check digit. Maybe it was meant that the other systems allow manufacturers more leeway to determine the content of some of the fields? JZH 14:50, 30 November 2006 (UTC)
[edit] Model Year
Does anybody know what they're planning on doing after the 2009 model year, when the alphanumeric space for that runs out? *Dan T.* 01:46, 29 May 2006 (UTC)
- Start over at A and repeat the same sequence, according to: http://www.autofacts.ca/classics/vininfo.htm#17digitVIN *jw* 216.183.126.166 21:39, 22 September 2006 (UTC)

- Confirmed by the applicable US government regulation, here: 49CFR565.6 JZH 14:57, 30 November 2006 (UTC)
[edit] Should source code be in this article?
The source code for check digit calculation in several programming languages seems jarringly out of place in this article. I think it would be more fitting to move that to a separate article and linking to that from here. Objections? -- 206.183.122.101 20:20, 31 May 2006 (UTC)
- If you feel the need to provide a repository of source code in Wikipedia, then move it to another article. I would remove it altogether. --Mormegil 07:19, 2 June 2006 (UTC)
That was foolish to remove the code. Some of the code had more detail than your remaining summation, and the purpose of VINs is validation and decoding. Providing validation implementation examples is what people need from a good article, just like they need the table of decoding keys and values.
[edit] Classic Car VIN Decoding
The free site Decode This provides VIN decoding services for VINs previous to 1980 which the currently listed site does not provide. I think it should be included in the external links. Chronosafe 23:12, 29 March 2007 (UTC)
