Barcodes & ID Keys
This section gives you the opportunity to understand barcodes. It too provides assistance in their implementation through ID Key Standards, Barcode Support Tools, Barcode Implementation Guides, and Barcode EPC Interoperability.
Barcodes & ID Key Standards
GS1 General Specifications
The core standards document describing how barcodes and identification keys should be used to comply with GS1 standards.
GTIN Allocation Rules
A Global Trade Item Numbers (GTIN) are used to identify any item upon which there is a need to retrieve pre-defined information and that may be priced or ordered or invoiced at any point in any supply chain.
GLN Allocation Rules
Global Location Number (GLN) provides the global supply chain solution for the identification of physical locations and legal entities.
Barcode Support Tools
GS1 DataBar (RSS)
The GS1 DataBar (RSS) identifies small items and carries more information than the current EAN/UPC barcode.
GS1 Company Prefix
The GS1 Company Prefix provides a way for GS1 Member Companies to uniquely and globally identify things like trade items, logistic units, locations, parties, and assets.
GS1 Identifiers (Keys and Attributes) - Overview
GS1 Keys identify trade items (GTIN), locations/trading parties (GLN), logistic units (SSCC), groupings of logistics units (GSIN) & (GINC), individual assets (GIAI), returnable assets (GRAI), service relationships (GSRN), document types (GDTI), coupons (GCN), component and parts (CPID)
GS1 Identification Key Types
GS1 Identification Keys that support the identification of items, services, locations, logistic units, returnable containers, etc.
Types of bar codes used by GS1 members
Barcode scanner and printing methods (PDF)
GS1 Barcodes are scanned in different places so GS1 specifies what barcode can be used where and establishes specifications for its use
GS1 Prefix List
This is a list of prefixes assigned by GS1 to GS1 Member Organisations or to specific applications.
Barcode Implementation Guides
1D Barcode Verification Process Implementation Guideline
This implementation guide provides instructions for creating a consistent verification service for testing bar code quality as well as data integrity
2D Barcode Verification Process Implementation Guideline
This guideline explains the practical implications of verification GS1 2D barcodes
