EPCIS 2.0
The global standard for capturing and sharing supply chain events — what happened, when, where, and why.
What is EPCIS?
EPCIS (Electronic Product Code Information Services) is a GS1 standard for creating and sharing visibility event data. It answers the four key questions of supply chain visibility:
What
Which products or assets are involved, identified by GTIN, SSCC, or other GS1 keys.
When
The date and time the event occurred, with timezone precision.
Where
The physical or digital location, identified by GLN or geo-coordinates.
Why
The business context — shipping, receiving, transforming, or destroying.
EPCIS 2.0: What's New
EPCIS 2.0 modernizes the standard with a REST/JSON API, replacing the legacy SOAP/XML interface. Key improvements:
- REST API — Modern JSON-based API with OpenAPI documentation
- JSON-LD — Linked data format for semantic interoperability
- GS1 Digital Link URIs — Use Digital Link URLs as event identifiers
- Sensor Data — Native support for IoT sensor readings (temperature, humidity)
- Simplified Queries — RESTful query interface replaces complex SOAP queries
Event Types
ObjectEvent
An observation of physical objects — scanned, shipped, received, or inspected.
AggregationEvent
Items packed into or unpacked from a container (e.g., cases onto a pallet).
TransformationEvent
Input items transformed into output items (e.g., ingredients into a finished product).
TransactionEvent
Objects associated with a business transaction (e.g., purchase order, invoice).
Why EPCIS Matters
EPCIS enables end-to-end supply chain visibility across trading partners. Combined with GS1 Digital Link, it powers:
- FSMA 204 Compliance — Record Critical Tracking Events for food traceability
- Digital Product Passports — Track product lifecycle from manufacture to recycling
- Anti-Counterfeiting — Verify product authenticity through supply chain event history
- Sustainability Reporting — Calculate carbon footprint across the supply chain
