Traceability

EPCIS 2.0 event capture and provenance timelines for lot-level and serial-level supply chain tracking.

Overview

GTIN1's traceability system captures supply chain events using the GS1 EPCIS 2.0 standard. Each event records what happened, when, where, and why -- creating a complete chain of custody from production to consumer.

EPCIS 2.0 Events

EPCIS (Electronic Product Code Information Services) is the GS1 standard for sharing supply chain visibility data. GTIN1 supports the four core EPCIS event types:

ObjectEvent

Records an observation or action on one or more objects. Used for commissioning, inspecting, shipping, receiving, and selling.

AggregationEvent

Records the association or disassociation of objects (e.g., packing items into a carton, loading cartons onto a pallet).

TransactionEvent

Links objects to business transactions such as purchase orders, invoices, or shipping notices.

TransformationEvent

Records the transformation of input objects into output objects (e.g., raw ingredients into a finished product).

Provenance Timelines

Every lot and serialized item in GTIN1 has a provenance timeline -- a chronological view of all EPCIS events associated with that item. When a consumer scans a QR code for a lot or serial, the hosted product page displays this timeline, showing the journey from production to shelf.

Granularity Levels

Lot-Level Traceability

Track entire production runs with lot identifiers (AI 10). Ideal for food products, pharmaceuticals, and any industry where batch recall capability is required.

Serial-Level Traceability

Track individual units with serial numbers (AI 21). Provides the highest granularity for luxury goods, high-value items, and products requiring unit-level chain of custody.

FSMA 204 Compliance

GTIN1's traceability features are designed to support FSMA 204 compliance:

  • Lot-level tracking with traceability lot codes
  • Critical Tracking Event (CTE) recording
  • Key Data Element (KDE) capture
  • Audit-ready export of traceability records

API Integration

Capture EPCIS events programmatically via the GTIN1 API. The API accepts EPCIS 2.0 JSON-LD events and automatically links them to the corresponding trade items, lots, and serials in the product registry.
