C# GS1-128 / EAN-128 Generator Introduction
Top
GS1-128, former known as EAN-128, UCC-128, USS-128, is alphanumeric linear barcode developed on Code 128, however, using GS1 standard.

C# GS1-128 Generator is one of the functions in OnBarcode's Barcode in .NET Generation Controls, which supports generating & printing GS1-128 / EAN-128 and 20+ other linear & 2D bar codes for C# applications.
OnBarcode C# Barcode Generator makes it easy to generate, create GS1-128 and other linear & 2d barcodes in Microsoft Word. Here are some detailed tutorials for C# GS1-128 generation and data encoding, size & image setting.

EAN-128 Generator library, SDK & application

OnBarcode provides several EAN-128 Generator components and software, including GS1 128 .NET, GS1 128 Java, GS1 128 VB.NET, GS1 128 ASP.NET, GS1 128 Generator.
This document is providing a detailed C# source code about generating GS1-128 barcodes in C# class using Barcode in C# generation component. Complete GS1-128 custmoization settings is included in C# GS1-128 generation guide.




GS1-128 data encoding using C#

  • The GS1 system requires that only the subset of ISO/IEC 646 International Reference Version defined in these GS1 General Specifications be used for GS1 Application Identifier (AI) element strings.

  • Characters with ASCII values 128 to 255 may also be encoded in Code 128 symbols.

  • Four non-data function characters

  • Four code set selection characters

  • Three start characters

Note: using .NET Barcode Generator SDK, you need provide AI elements data only, the software will add all other characters for you.
