How do I enter Application Identifiers?

Put the AI in round brackets immediately followed by its data, e.g. (01)08712345678906(17)261231(10)LOT42. The brackets themselves are not encoded, they only define the structure.

Which AIs are most common?

(01) GTIN, (10) batch/lot, (11) production date, (17) expiry date, (21) serial number, (30) count, (37) units, (00) SSCC.

Is GS1-128 the same as an SSCC label?

An SSCC pallet label uses GS1-128 with AI (00). The full label also carries human-readable text following the GS1 logistics label guideline.

GS1-128

GS1-128 (formerly EAN-128) uses Code 128 with an agreed data structure: Application Identifiers in brackets declare what each data block means. (01) is the GTIN, (17) the expiry date and (10) the batch or lot number.
