91iD™ LAUNCH & NETWORK MISSION

91iD™ Numbering System

91iD™ Numbering System

An Independent Product Identity Network

91iD™ is independently operated as a product identification and verification network. A 91iD™ identifier is its own proprietary/private reference and does not require a GS1 GTIN to exist as a 91iD™ identifier. Where a product or marketplace is subject to a separate regulatory, retailer, marketplace or standards requirement, those requirements remain applicable.
