Prefixes:
It seems to be the list of prefixes is the list of EAN (now GTIN-13) prefixes. If I understand correctly, the list of prefixes for GTIN (GTIN-14) should be
* 0020 - 0029 Restricted distribution (GS1 MO defined) * 0040 - 0049 Restricted distribution (GS1 MO defined) * 0050 - 0059 Coupons * 0200 - 0299 Restricted distribution (GS1 MO defined) * 0977 Serial publications (ISSN) * 0978 - 0979 Bookland (ISBN) * 0980 Refund receipts * 0981 - 0982 Common Currency Coupons * 0990 - 0999 Coupons
Can someone confirm?

[edit] Book abuse of GTIN in UPCs (the EANS are fine)
Books that have UPCs (rather than or in addition to EAN barcodes) often seem to violate the GTIN concept.
For example: I'm looking at a book right now (picked one up randomly) that has an ISBN-10 of:1-57566-324-4, Therfore the ISBN-13 is 9781575663241. It has a list price of 22 USD.
It has 2 barcodes, both using the 5 digit extention code. The one is EAN+5: 9781575663241+52200 The other is a UPC-A+5:752550022000+00324 If that is rendered as a bar code you will notice the second group of digits is "02200". That is the price. the Extention gives the title code from the ISBN. Apparently the book publisher claims that all its books with a list price of 22 USD are in fact the same product, as it has assigned the same GTIN-12 to all of them (752550022000).
What an absurd practice. The only logical explanation i have come up with is that they wanted to make it very difficult to individually reprice books if your equipment will only read UPCs, and does not support the extension codes.
With the EAN system the extension code is not necessary to uniquely identify the product, which is how it should be.
[edit] ISSNs

ISSNs are 8 digits + check digit = 9 digits. There's a three-digit country code for them; that makes 12 digits. How does one construct a GTIN-13 from that? -- Beland 21:48, 18 July 2007 (UTC)
