BarCodes & Identification

BarCodes

The GS1 System provides for the use of unambiguous numbers to identify goods, services, assets, and locations worldwide. These numbers can be represented in bar codes to enable their electronic reading wherever required in business processes.

The system is designed to overcome the limitations of using company, organisation, or sector specific coding systems, and to make trading much more efficient and responsive to customers.

additional information

In addition to providing unique identification numbers, the GS1 System provides for supplementary information, such as best before dates, serial numbers, and batch numbers, which can appear in bar code form. Currently, bar codes are used as the data carriers, but other technologies, such as radio frequency tags are being developed within EPCglobal as carriers of GS1 data. Changes take place only after wide consultation and are subject to a significant migration period.

industry independent

The GS1 System is designed that guarantees the interoperability between different industries. New developments in the standard will be introduced in a way that existing implementations are not affected.

GS1 Company Prefix (GCP)
The GS1 Company Prefix is a part of GS1 data structures. It consists of a GS1 Prefix, which is administered by GS1, and a Company Number, which is assigned by a GS1 Member Organisation. The GCP is is used to create all GS1 Identification Keys.
Allocation of GS1 numbers
A GS1 Company Prefix gives access to all the applications using GS1 System identification standards. A GS1 Company Prefix assigned to a member of GS1 Switzerland entitles that member to create any of the GS1 Identification Keys.

GS1 Identification Keys
GS1 Identification Keys are used to identify trade items, logistic units, locations, legal entities, assets, service relationships, consignment, shipments and more. GTIN, SSCC and GLN are the most widely used GS1 ID Keys.
Data Carriers in the GS1 System
The barcode technology is based on the recognition of patterns that are coded with lines and spaces in different sizes. Read more to get a basic understanding of the GS1 Barcode Symbologies, such as EAN-13, GS1-128, ITF-14, GS1 DataBar or GS1 DataMatrix.
GS1 Application Identifier (AI)
Die GS1-128 Application Identifier (AI) zeichnen sich durch drei wichtige Eigenschaften aus, die ihn in Verbindung mit geschützten Datenträgern wie dem GS1-128-Strichcode weltweit einzigartig machen:
