GTIN is an “umbrella” term used to describe the entire family of GS1 data structures for '''trade items''' (products and services) identification. GTIN numbers are 14 digits long. GTIN can be constructed using four numbering structures, depending upon the exact application and the bar code symbology to be used. The Numbering Structures that can be found in the 14-digit Global Trade Item Number (GTIN) are : GTIN-14, (0+GTIN-13), (00+GTIN-12) and (000000+GTIN-8). GTIN-12 is encoded in a UPC-A bar code. The GTIN-8 is an 8-digit code used usually for very small articles, such as Bubblegum , where fitting a larger code would be problematic. The numbering structure is composed of:
All books and serial publications sold internationally (including those in U.S. stores) have GTIN (GTIN-13) codes. The book codes are constructed by prefixing the ISBN number with 978 and recalculating the trailing Checksum digit. Since each trade item is given its own GTIN, it may be helpful to note that the term trade item refers to any product or service upon which there is a need to retrieve pre-defined information; this product or service may be priced, ordered, or invoiced at any point in the Supply Chain . This includes individual items as well as all of their different packaging configurations. In February 2005, employees and booksellers of Barnes & Noble were informed that beginning at the end of March, their computer systems were going to add the ability to search by EAN to facilitate a switch over to the EAN from the current standard of ISBN codes. Receipts will now list the EAN, rather than the ISBN. Since all existing 10-digit ISBN codes are mapped to a subset of the space of 13-digit EANs, booksellers' computer systems will still be able to search by ISBN (and UPC in the music departments) to help booksellers locate older books that have not been assigned an EAN number. By January 1 , 2005 the U.S. ISBN agency requires publishers be able to communicate ISBNs as GTIN-13. The new 979 prefix for publications will be available on January 1 , 2007 or upon assignment of the last 978 prefix. PREFIXES Each country gets one or several three digit prefixes assigned. {Link without Title} . Some special ranges exist. The usage for some is GS1 Member Organisation (GS1 MO) specific:
