EAN18 ???
The article talks of EAN18 - I think that is at least confusing if not entirely wrong.

Apparently EAN-18 is an unofficial name for the Serial Shipping Container Code - see "EAN-13 checksum even or odd" below. 86.147.155.155 (talk) 12:15, 25 September 2010 (UTC)

Conspiracy Theories
For fun and completeness the conspiracy theory may be mentioned, according to which some evil elite group of people (often referred to as illuminati) are the actual leaders of the world, and they are obsessed with putting secret signs on everything they control and own.

So it is true for every EAN-code, since it has an evil number 666 encoded in the separation/calibration character in the beginning, middle, and in the end. In fact, this character, the double line, encodes the six! However there is no reason to take the code for six for this purpose. The six has no sense in terms of binary encoding (like 2, 4, 8, etc.), and there is an eight which is also encoded as a symmetric double line, if the symmetry is a nessesary criterion for some reason.

EAN-13 Image
Unless someone disagrees I will be adding a correct EAN-13 image compliant with GS1 spec. (In particular it would include right quiet zone indicator and correct font OCR-B. I would also add printing considerations paragraph on the size of EAN-13 symbol.

How to calculate the checksum in Ruby
I think this is information that would be good to have in the article for the programmers but don't know where to add it. 195.198.87.143 07:30, 13 September 2007 (UTC)
 * Per WP:NOT, Wikipedia is not a how-to guide. This article is explaining what an EAN is and I don't believe that a code example is necessary to do that. Maybe some text might be added to make more precise how the checksum is defined, though. EdJohnston 01:39, 19 September 2007 (UTC)
 * I think code can be a good way to explain things, so not a how-to as much as a clarification. I'd probably prefer to use C or something a bit more standard than Ruby though.  Python maybe?  Pseudo-code? Hobit (talk) 18:05, 6 October 2010 (UTC)

EAN-13 Image... checksum digit
Are you sure the Ean13 example in the image is correct? In particular shouldn't the checksum be 2 rather than 5?

Unles I got something wrong these are my calculations:

2+0+3+2+1+8 = 16

0+1+0+5+1+7 = 14

16 + 3*14 = 58

60-58 = 2  <-- This is the checksum

 * Yep, you're right. Don't know how to notify the creator though. —Preceding unsigned comment added by 87.187.21.244 (talk) 12:49, 28 October 2007 (UTC)

EAN-13 so-called "parity"
The use of parity here is unusual in that it doesn't refer to a number's being even or odd, but just an arbitrary choice between two possible encodings. This is perhaps worth mentioning? — Preceding unsigned comment added by Obscaenvs (talk • contribs) 15:47, 6 October 2011 (UTC)

UNDUE with bookland?
Hi all, I think the current bookland/musicland sections put undue weight (WP:UNDUE) on this material. I've added a one-liner instead and would like to remove the whole book/music-land sections (or perhaps greatly prune them). Thoughts? (BTW, I added the one liner not noticing that those sections had been added. Not sure how that happened.  If we keep the section my one liner should refer to that section).

 * I'm aware of that and the DRV. I'm not certain what that has to do with the undue issue however. Hobit (talk) 12:57, 7 October 2010 (UTC)

Japanese Article Number merge proposal
As far as I can tell, the Japanese Article Number is either a synonym or a minor variation on the International Article Number scheme. At present, the JAN article is a stub- is there anything that could be added that wouldn't simply be a pointless duplication of the International Article Number article?

If not, IMHO they should be merged.
