Understanding the GTIN

The GTIN enables you to identify items in the standard EAN.UCC System. The GTIN is a product number that uniquely identifies the item, level of packaging, and manufacturer. Level of packaging refers to a standard quantity of units of the item which the unit of measure represents.

The system uses the RFID user-defined code (UDC) value for Number Type (46R/NT) for setting up the GTIN. This value is hard-coded. However, you can set up different unique product numbering types as needed in this UDC such as National Drug Code (NDC).
