The Global Trade Item Number (GTIN) is an identifier for trade items, developed by the international organization GS1. [1] Such identifiers are used to look up product information in a database (often by entering the number through a barcode scanner pointed at an actual product) which may belong to a retailer, manufacturer, collector, researcher, or other entity.
Numbering the positions from the right (code aligned to the right), the odd data digits are always weight of 3 and the even data digits are always weight of 1, regardless of the length of the code. Weights for 18-digit SSCC code and GTINs (GTIN-8, GTIN-12, GTIN-13, GTIN-14):
As there are an odd number of digits in the middle of the string, the odd one must use a different code set, but it makes no difference whether this is the first or last; 16 symbols are required in either case: [Start B] 0 9 8 x 1 [Code C] 23 45 67 [Code B] y 2 3 [checksum] [Stop], or [Start B] 0 9 8 x [Code C] 12 34 56 [Code B] 7 y 2 3 ...
It applies to GTIN-8, GTIN-12, GTIN-13 and GTIN-14. The final digit of a DUNS number (though this is scheduled to change, such as that the final digit will be chosen freely in new allocations, rather than being a check digit). The third and fourth digits in an International Bank Account Number (Modulo 97 check).
Both the Universal Product Code and EAN-13 identifiers that are still found on many trade items can be mapped into a 14-digit GTIN identifier, by padding to the left with zero digits to reach a total of 14 digits. An SGTIN EPC identifier can therefore be constructed by combining the resulting GTIN with a unique serial number and following the ...
In 1976, the original 12-digit code was expanded to 13 digits, which allowed the identification system to be used outside the U.S. ... Global Trade Item Number (GTIN ...
Each encodes a GTIN-12 or GTIN-13 in 14-digit data structure. Only GS1 DataBar Limited uses an indicator digit 1. In addition to encoding Application Identifier (01) GTIN, GS1 DataBar Expanded and GS1 DataBar Expanded Stacked can encode additional GS1 Application Identifiers such as sell-by date, weight, and lot number. Each symbol has a ...
Moreover, the 10-digit ISBN check digit generally is not the same as the 13-digit ISBN check digit. Because the GTIN-13 is part of the Global Trade Item Number (GTIN) system (that includes the GTIN-14, the GTIN-12, and the GTIN-8), the 13-digit ISBN falls within the 14-digit data field range. [57]
