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.
A UPC barcode. The Universal Product Code (UPC or UPC code) is a barcode symbology that is used worldwide for tracking trade items in stores.. The chosen symbology has bars (or spaces) of exactly 1, 2, 3, or 4 units wide each; each decimal digit to be encoded consists of two bars and two spaces chosen to have a total width of 7 units, in both an "even" and an "odd" parity form, which enables ...
The most commonly used EAN standard is the thirteen-digit EAN-13, a superset of the original 12-digit Universal Product Code (UPC-A) standard developed in 1970 by George J. Laurer. [1] An EAN-13 number includes a 3-digit GS1 prefix (indicating country of registration or special type of product).
GS1 is a not-for-profit, international organization developing and maintaining its own standards for barcodes and the corresponding issue company prefixes.The best known of these standards is the barcode, a symbol printed on products that can be scanned electronically.
However, the Global Trade Item Number (GTIN) only identifies the product type or stock-keeping unit rather than an individual instance of a particular product type. To ensure that an EPC always uniquely identifies an individual physical object, in the case of a GTIN, the EPC is constructed as a Serialised Global Trade Item Number ( SGTIN ) by ...
A GS1-128 barcode encoding GTIN, best before date and batch number. GS1-128 (formerly known as UCC/EAN-128) is a subset of Code 128 and is used extensively worldwide in shipping and packaging industries as a product identification code for the container and pallet levels in the supply chain.
GEPIR is a lookup service coordinated by the GS1 GO that provides all end users with the ability to look up information about GS1 Identification Keys. [ 6 ] Depending on the service, systems are provided by GS1 Member Organisations (MOs) or 3rd party service providers, or both.
It is encoded identically to the 12 digits of the UPC-A barcode, except that it has 4 (rather than 6) digits in each of the left and right halves. [citation needed] EAN-8 barcodes may be used to encode GTIN-8 (8-digit Global Trade Identification Numbers) which are product identifiers from the GS1 System. A GTIN-8 begins with a 2- or 3-digit GS1 ...
