UCC/EAN Barcode Font (GS1-128)
UCC EAN is an international barcode format used widely by many different companies. It uses a list of Application Identifiers (AI) for identifying the structure and format of the data in the barcode. For example, AI 00 is used for identifying a 18 digits Serial Shipping Container Code.The UCC/EAN uses the Code 128 barcode font and specifically the Code 128 Auto character set.

Using the UCC/EAN barcode font
It is recommended to use the Encoder or VB macros provided to generate UCC/EAN barcodes as 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
UCCEAN (also known as GS1 128 barcode), is a very important barcode used by many logistics, warehouses and manufacturing firms in their daily activities. Each of these companies may implement its own warehouse management systems differently and adopt different UCCEAN barcode scanning algorithms. Some may implement the scanning algorithms very strictly while others may allow flexibility in the barcode as long as it adheres to the general GS1 specifications.
ConnectCode supports the different variations through a Strict GS1 128 Compliance option. When this option is selected, the barcode generated adheres strictly to the UCCEAN / GS1 128 specifications. Otherwise it generates a barcode that can be read by the scanning algorithm of many legacy systems. This gives users a choice to choose the preferred implementation of the UCCEAN barcode as required by different organizations with various scanning devices and systems.
If you are new to this barcode, you may want to use the default implementation and leave the checkbox unchecked. In the event that the default (legacy) implementation does not meet the strict conditions required by some companies, you may want to turn on the Strict GS1 128 Compliance option.
Default/Legacy Implementation
The following shows the structure of the UCCEAN barcode generated using the default / legacy implementation. This implementation is usually accepted by most warehouse and logistics firms.| UCCEAN Barcode (Default Implementation) |

Strict GS1 128 Compliance
The following shows the structures of 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.
