About GS1-128
GS1-128 uses Code 128 with GS1 application identifiers for data such as GTIN, batch, expiry and serial number.
Follow GS1 application identifier syntax exactly and validate the complete data structure with your trading partner.
Practical implementation notes
GS1 symbols carry structured business data, not just a product ID. Application identifiers define each field, including its length and meaning. A missing separator or incorrect date format can make a symbol unreadable to a receiving system even when a scanner can physically read it.
