GS1-128 - Barcode Type¶

A variation of Code 128, also known as UCC/EAN-128, this symbology is defined by the GS1 General Specification. Application Identifiers (AIs) should be entered using [square brackets] notation. These will be converted to (round brackets) for the human-readable text. This will allow round brackets to be used in the data strings to be encoded. Fixed length data should be entered at the appropriate length for correct encoding (see Appendix C). GS1-128 does not support extended ASCII characters. Check digits for GTIN data (AI 01) are not generated and need to be included in input data.
