GS1 Barcode Syntax Resource
Overview
The GS1 Barcode Syntax Resource is a collection of assets that provides the tools required by solution providers and users to correctly implement, apply and stay aligned to GS1 standards in a simple and consistent manner.
By adopting the GS1 Barcode Syntax Resource, solutions can easily create and process conformant GS1 syntaxes encoded to linear or 2D barcodes used within the GS1 system. This enables industry and the broader GS1 user community to leverage the full benefits of using any barcode or syntax from the GS1 system, to experience a truly interoperable and standardised implementation of GS1 standards for all their operational data needs, while facilitating the global migration to 2D barcodes, no matter what their chosen solution may be and where they are on their 2D journey.
Provides foundational GS1 Application Identifiers (AI) validation rules and logic for the consistent implementation of GS1 standards, enabling the detection of common data errors before they are encoded into barcodes.
Facilitates the interpretation of GS1 Application Identifiers (AI) and conversion between the different GS1 syntaxes used with linear and 2D barcodes within the GS1 system.
Offers an easy way to keep up to date with GS1 standards, as new GS1 Application Identifiers (AI) and conformance rules are added to the system.

Additional resources
GS1 Barcode Syntax Resource Demo Tool
This tool showcases an example implementation of the GS1 Barcode Syntax Resource, enabling users to input data either through a keyboard or a barcode scanner. It allows users to test whether their data strings conform to GS1 standards and how the data may be translated into other GS1 syntaxes. The supported data syntaxes are displayed on the right-hand side of the tool, while tooltips offer further information about data input.

How to use the GS1 Barcode Syntax Resource
The GS1 Barcode Syntax Resource is a versatile suite of tools that enables easy and consistent implementation of GS1 standards for both new and existing solutions. The assets can be fully or partially implemented based on the user's requirements, and serves as a foundation for building application or user-specific requirements.
Consisting of three components, the GS1 Barcode Syntax Resource can be integrated directly into an application’s code base or simply used as a reference for transliteration into third-party code as required by the solution’s build system.
Take a closer look at each component, by clicking the tiles below:
GS1 Barcode Syntax Dictionary
A simple, open-source text file that contains a list of all currently assigned GS1 Application Identifiers (AIs) and the necessary components for creating a valid GS1 data syntax.
GS1 Barcode Syntax Tests
A set of source code files that provides instructions to perform a series of analytical actions to check if data, whether input by a keyboard or barcode scanner, is valid against GS1 conformance specifications and rules for the GS1 data syntax.
GS1 Barcode Syntax Engine
An example of the harmonised framework required to implement the GS1 Barcode Syntax Dictionary and GS1 Barcode Syntax Tests, to facilitate the detection and conversion of GS1 syntaxes.
GS1 DataMatrix with GS1 element string syntax
EAN-13 with plain syntax
QR code with GS1 Digital Link URI syntax

GS1 General Specifications
The core standards document of the GS1 system, that describes how GS1 barcodes and identification keys should be used.
GS1 Digital Link standard
Extends the power and flexibility of GS1 identifiers by making them part of the web, enabling the use of a single barcode for traditional B2B purposes such as point of sale, as well as B2C access to digital information about the entity being identified.
