UCC/EAN (GS1-128) Barcode Fonts

GS1-128 Barcode Font (UCC/EAN)

GS1-128 (UCC/EAN) is a standard developed by the GS1 organization for exchanging data. This standard uses a list of Application Identifiers (AI) for defining the format, structure, and meaning of the data. For example, a Serial Shipping Container Code (SSCC) is identified by the AI 00, followed by 18 digits that comprise a GS1 company prefix and a serial reference. The GS1-128 barcode uses the Code 128 barcode symbology as the underlying barcode symbology and is also commonly known as UCC-128 and EAN-128 barcode.

Using the GS1-128 (UCC/EAN) barcode font

It is recommended to use the Encoder or Excel VB macros provided to generate GS1-128 (UCC/EAN) barcodes. There are several steps required for transforming the input data to characters recognized by the barcode font. For example, to encode AI 00 (Serial Shipping Container Code) with the data 123456789012345675

Input (Using the Encoder or VB macros):

(00)123456789012345675

The brackets are used to identify the AI(Application Identifier) in the Encoder.

Output:

The last digit '5' is a MOD 10 check digit that can be entered (as shown above) or calculated automatically by ConnectCode Barcode Fonts package. For more information, see the MOD 10 Check Digit subsection.

Concatenating multiple AIs

Input (Using the Encoder or VB macros):

(00)123456789012345675(12)1A

Multiple AIs can be concatenated together as shown above. A total of up to 8 AIs concatenation is supported by ConnectCode.

Output:

GS1-128 compliance

A GS1-128 barcode may contain more than 1 AIs and an FNC1 character is usually used to separate them. The GS1-128 specification further specifies that an FNC1 character is not required following an AI with fixed-length data. However, some early GS1-128 barcodes have adopted the format where an FNC1 character is always used to separate the AIs in the same barcode.

ConnectCode supports the different variations through a Strict GS1 128 Compliance option. When this option is enabled, the barcode generated adheres strictly to the UCCEAN/GS1-128 specification. Otherwise, it generates a barcode that always uses the FNC1 character as the separator. If you are new to this barcode, we recommend using the Strict GS1 Compliance option, in compliance strictly to the specification.

The following shows the structure of the GS1-128 (UCCEAN) barcode generated using the default/legacy implementation.

Strict GS1 128 Compliance

The following shows the structures of GS1-128 (UCCEAN) barcodes generated using the Strict GS1 128 Compliance mode. This implementation is accepted by organizations that require a stricter implementation. The main differences are

1. This mode may create even shorter barcodes because it employs subset C compression whenever the data consists purely of digits.

2. Also, the FNC1 character, a special marker used to separate multiple application identifiers in the barcode, is used only when the particular application identifier is associated with variable data.
