Overview

Identification of trade items contained in a logistic unit: AI (02)

The GS1 Application Identifier (02) indicates that the GS1 Application Identifier data field includes the GTIN of the contained trade items. The GTIN is used to identify trade items (see section 4).

The GTIN for trade items may be a GTIN-8, GTIN-12, GTIN-13 or a GTIN-14. See section 2 for the rules for GTIN formats and mandatory or optional attributes in the various trade item applications.

The GTIN of the trade items contained is the GTIN of the highest level of trade item contained in the logistic unit.

Note: This element string SHALL be used only on a logistic unit if:

  • the logistic unit is not itself a trade item; and

  • all trade items that are contained at the highest level have the same GTIN

The check digit is explained in section 7.9. Its verification, which must be carried out in the application software, ensures that the number is correctly composed.

The data transmitted from the barcode reader means that the element string denoting the GTIN of trade items contained in a logistic unit has been captured. This element string must be processed together with the count of trade items, AI (37), which must appear on the same unit (see section 3.6.5). When indicating this element string in the non-HRI text section of a barcode label, the following data title SHOULD be used (see also section 3.2): CONTENT
