Item identifier
Item Identifiers (Additional Item Id)
An Item Identifier is an identification code for an item. While GS1 typically uses GTINs (8-14 digits), Hii Retail supports various types, including non-standard codes, PLUs, QR codes, and alternative SKUs.
Item Identifier Types
All GTIN types are validated for length and check digit, and checked for duplicates within your tenant. Duplicate GTINs are ignored and logged, and a Customer Notification event is sent. See External Events service.
Variable measure GTIN ranges (prefixes 02, 20-29) are not checked for duplicates.
