UCC/EAN-128
UCC/EAN-128 is a variation of the Code 128 symbology. The distinguishing feature of the UCC/EAN-128 is its Application Identifier (AI) prefix. An AI is a numeric two, three, or four digit prefix that defines the structure of the data that follows it. For example, the AI for the SSCC-18 is (00), which means that every time a (00) AI precedes the data in the UCC/EAN-128, you know that the data is formatted for the SSCC-18. The UCC/EAN-128 symbology is also characterized by its unique start code pattern that consists of a start code A, B, or C character and a Function 1 (FNC1) character. The UCC/EAN-128 bar code symbology includes:
- A start code (a start character A, B, or C and a FNC1 character)
- The data (the AI and the data fields)
- A Mod 103 checksum (in the bar code, not in the human readable)
- A stop character
All UCC/EAN-128 symbologies use a required Mod 103 checksum (not in human readable form)
