GS1 Application Identifiers

In supply chain and physical commerce systems, physical locations serve as core spatial anchors for goods storage, circulation and handover. For a long time, inconsistent internal location coding rules across enterprises have prevented direct mutual recognition of cross-entity and cross-system location information, resulting in inaccurate inventory positioning, low handover efficiency, and missing spatial dimensions in […]

In the supply chain logistics system, shipment is the core business node of goods circulation from the shipper to the consignee. A unified identification for shipment batches is the foundation for collaborative management of the whole outbound, transport and receipt process. For a long time, inconsistent shipment numbering rules across enterprises have led to low

In the global multimodal transport system, a single consignment often passes through multiple carriers, transport modes and transit nodes before delivery. For a long time, consignment numbering rules have been defined independently by each logistics enterprise, requiring repeated document matching and manual data entry during cross-party handover. This not only drags down efficiency but also

In the global retail and fast-moving consumer goods industry, coupons are a core marketing tool to drive sales and boost customer repurchase rates. However, the long-standing lack of unified coupon coding rules has led to cross-platform redemption difficulties, high fraud risks and fragmented data. As a dedicated standard of the GS1 global identification system for

In the global supply chain system, trade documents, compliance certificates and technical reports are core carriers of business circulation and compliance governance. For a long time, the lack of globally unified standards for document identification has made cross-enterprise and cross-system document verification rely on manual checking, resulting in low efficiency, high error rates and traceability

In the global supply chain system, unified identification of trade items is the foundation for automated checkout, inventory management and end-to-end traceability. As a core component of the GS1 global identification system, the Global Trade Item Number (GTIN), carried by GS1 Application Identifier (AI) 01, is currently the most widely adopted product identification standard worldwide.

In today’s globalized, multi-tier supply chain system, finished products are often assembled from hundreds or even thousands of components and parts. For a long time, however, component identification has suffered from inconsistent coding rules, cross-enterprise recognition difficulties, and broken traceability chains — all of which directly undermine the efficiency and accuracy of product recalls, after-sales

Within the GS1 global identification system, the Global Trade Item Number (GTIN) solves the identity recognition problem for individual items and trade units. However, for cross-enterprise unified identification and full-lifecycle management at the product model level, a dedicated standardized coding framework is required. GS1 Application Identifier (AI) 8013, corresponding to the Global Model Number (GMN),

Within the GS1 global identification system, while the widely known GTIN (Global Trade Item Number) is used for physical goods identification, GS1 has also established a dedicated Global Service Relation Number (GSRN) framework for service supply chain relationship management. As the core identifier for service provider relationships within the GSRN system, GS1 Application Identifier (AI)

Within the GS1 Global Identification System, AI 8018 (Global Service Relation Number – Recipient, GSRN‑RECIPIENT) is the core primary identifier exclusively dedicated to service recipients. As a first‑class primary key in the GS1 Digital Link URI ecosystem, it maps offline service relationships into the digital space, enabling globally unique identification, end‑to‑end traceability, and trusted data
