Which data elements/Application Identifiers (AI) should/must be used

Modified on Mon, 2 Jun at 8:51 AM

Mandatory is the GTIN (01), SGTIN [= GTIN + serial number - (01)+(21)] or GIAI (8004) to identify the object, all other/additional data elements/AI are optional (less is more).


Data Element = GS1 Application Identifier (AI) + Data Field [General Specifications (GS) 3.1]; GS1 Application Identifiers are a two to four digit number at the beginning of a data element to define the subsequent data fields. In the case of serialised products, the SGTIN or the GIAI should be sufficient in the future to obtain further information in associated databases by serving as an access key.
