What Is GS1-128 Barcode?

In general, GS1-128 (also known as UCC/EAN-128) is a Code 128 derivative language that employs a flagging character (Function Code 1 (FNC1)) and application identifiers.

It was developed to create a universal standard for data exchange between enterprises. 

It not only encodes the data but also defines the meaning of the data by creating a list of "Application Identifiers," which is a GS1 Standard that defines the kind of data as well as the data format. 

The barcode data also allows for the stringing together of several Application Identifiers. Data like serialization and expiry may be encoded thanks to this capability.

GS1-128 Barcode Components

The components of GS1-128 include:

  • Code 128 start character (START-A, START-B, or START-C)

  • Code 128 FNC1 character

  • Application Identifier (AI)

  • Encoded Data

  • Symbol Check character

  • Stop Character

GS1-128 Barcode Application Identifier

Each GS1-128 symbol encodes one or more AI to specify the type of data being encoded. 

In most cases, AI also determines the length and format of the data. 

The next 2-4 digits reflect the relevant AI when a Code 128 barcode with a leading FNC1 character is scanned. 

For instance, the scanner would anticipate an 18-digit numeric SSCC-18 data to follow if the encoded data after the FNC1 character was "00".
