class GS1::GTIN
Identification of a trade item (GTIN
): AI
(01)
The GS1
Application Identifier (01) indicates that the GS1
Application Identifier data field contains a GTIN
. 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 2.1 for the rules for GTIN
formats and mandatory or optional attributes in the various trade item applications.
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.
