GS1 Standards Library
Start here for quick access to all of the GS1 standards and EPCglobal technical standards.
Barcode Summary & Usage: Summarizes all GS1 barcodes and their uses.
Core Business Vocabulary (CBV) Standard: Complements the EPCIS standard, providing common definitions of business process steps and the disposition of physical goods.
Discovery, Configuration & Initialization (DCI): Specifies an interface between RFID Readers and Access Controllers and the network on which they operate
EAN/UPC: Barcode symbology (including the UPC-A, UPC-E, EAN-13 and EAN-8 barcodes) used exclusively for products scanned at retail point of sale.
Electronic Data Interchange (EDI): Enables the computer-to-computer exchange of business documents between companies using a standard format, regardless of the kind of computer or software each company is using
Electronic Product Code (EPC): Provides the means to use the same GS1 standard identifiers used with barcodes, by encoding them into RFID tags.
Electronic Product Code Information Services (EPCIS): Standard for sharing EPC-related information between trading partners.
EPCglobal HF air interface protocol: Defines the physical and logical requirements for a passive-backscatter, Interrogator-talks-first (ITF), radio-frequency identification (RFID) system operating in at 13.65 MHz frequency.
EPCglobal UHF “Gen2” air interface protocol: Defines the physical and logical requirements for a passive-backscatter, Interrogator-talks-first (ITF), radio-frequency identification (RFID) system operating in the 860 MHz - 960 MHz frequency range.
Global Coupon Number (GCN): Identifies a coupon
GDSN Package Measurement Standards and Guidelines: GS1 Standards document that include the GDSN Package Measurement Rules. These rules establish global standards to facilitate the measurement of linear dimensions and weights for retail and non-retail products from the consumer unit to the non-consumer level and all intermediate packaging levels in between.
GDTI (Global Document Type Identifier): Identifies a document by type and is used when it is important to maintain a record or “master copy” of a document.
GINC (Global Identification Number for Consignment): Identifies a logical grouping of logistics units that are assembled to be transported together under one transport document.
GIAI (Global Individual Asset Identifier): Identifies, manages and tracks a company’s fixed assets/property, such as office equipment, furniture, computers and manufacturing equipment.
GLN (Global Location Number): Reference keys for retrieving information about locations related to the supply chain.
Global Data Synchronization Network (GDSN): Enables the sharing of accurate and up-to-date data and information among trading partners; for example, any changes made to one company’s database are automatically and immediately provided to trading partners.
GRAI (Global Returnable Asset Identifier): Identifies a reusable package or transport equipment, such as pallets, barrels, gas cylinders, beer kegs, rail cars, and trailers.
GS1 Company Prefix: Forms the base for the GS1 family of identifiers that are globally unique and can be used for a host of different applications.
GS1 DataBar™: Barcodes that can carry more information in less space than U.P.C. barcodes. Like a GS1-128, DataBar can carry both a GS1 identifier, plus additional standardized data.
GS1 DataMatrix: Two-dimensional (2D) barcode that holds large amounts of data in a relatively small space.
GS1 General Specifications: Master standards document defining how barcodes and identification numbers should be used to comply with GS1 Standards.
GS1 QR Code: Two-dimensional (2D) barcode that holds large amounts of data in a relatively small space. Primarily used in marketing applications.
GS1-128: Barcodes used to encode product data for units such as cartons, cases, pallets, and reusable packaging or transport equipment (returnable assets) and help manage fast and accurate tracking of inventory: Can carry both a GS1 identifier, plus additional standardized data.
GSIN (Global Shipment Identification Number): Identifies a grouping of logistics units that comprise a shipment from one consignor to one consignee (buyer) referencing a despatch advice and/or BOL.
GSRN (Global Service Relationship Number): Identifies the recipient of services in relationships such as hospital admissions, membership in frequent flyer and loyalty programs, and warranties for computers and other items.
GTIN (Global Trade Item Number): Identifies all “trade items,” which include products and services that are sold, delivered and invoiced at any point in the supply chain.
ITF-14: Barcodes are used to uniquely identify units such as cartons, cases and pallets and help manage fast and accurate tracking of inventory.
Low Level Reader Protocol: Specifies a standard interface between RFID Readers and Clients.
Reader Management: Used by management software to monitor the operating status and health of EPCglobal compliant RFID Readers.
RosettaNet: Provide business frameworks that allow individual companies to enhance the interoperability of business processes across the global supply chain.
SSCC (Serial Shipping Container Code): Identifies logistics units, such as cases, cartons, pallets, or air cargo containers of trade items as they travel through shipping and receiving
Tag Data Standard: Defines EPC tag data, including how key GS1 key identifiers are encoded on the tag and how they are encoded for use in the information systems.
Tag Data Translation Standard: Defines a machine-readable version of the EPC Tag Data Standards specification as well as translating between the different levels of representation in a consistent way.
UNSPSC: Provides an open, global multi-sector standard for efficient, accurate classification of products and services.
eXtensible Markup Language (XML): Allows for the electronic transmission of business documents in a format that is readable by both machines and by people.
