GS1 Traceability and Barcode Standards for Distribution Training Course

Course overview

Distribution networks lose time and accuracy when product identifiers change between suppliers, warehouses, carriers and customers. A warehouse may receive a supplier barcode that cannot be matched to its item master, ship a case with the wrong GS1-128 application identifier, or investigate a recall using shipment records that do not link lots, serial numbers and locations. These failures create receiving exceptions, chargebacks, inventory disputes, delayed recalls and weak evidence for customers or regulators. This course gives supply chain professionals a practical method for designing and operating traceable distribution processes using GS1 Standards.

Participants learn how GTINs, GLNs, SSCCs, GS1-128 barcodes, DataMatrix symbols, application identifiers and EPCIS event data work together across inbound, storage, picking, dispatch and returns. They interpret barcode content, assign and validate logistics identifiers, create SSCC-based pallet labels, and map critical tracking events to business processes. The course also addresses master-data governance, label quality, scanner configuration, supplier onboarding and exception management, so participants can distinguish a barcode-printing problem from an identification, data-quality or process-control failure.

Instruction combines worked standards examples, label-reading exercises, distribution case studies and facilitated design workshops. Participants use a realistic multi-site distribution scenario to develop a GS1 traceability blueprint: identifier rules, event-capture requirements, barcode-label specifications, data ownership roles, exception procedures and implementation priorities. They leave with a structured action plan that can be adapted for a warehouse, supplier network, 3PL operation or customer compliance programme.

The course is suited to professionals who already work with inventory, warehousing, logistics systems or product data and need to make identification and traceability controls operational rather than theoretical.

Course objectives

By the end of this course, participants will be able to:

• Interpret GTIN, GLN and SSCC structures and determine their correct use in distribution transactions
• Apply GS1 Application Identifiers to encode batch, expiry, serial, quantity and logistics-unit data
• Create a GS1-128 logistics label specification with SSCC, human-readable text and barcode placement rules
• Map EPCIS 2.0 ObjectEvent, AggregationEvent and TransformationEvent records to warehouse movements
• Define critical tracking events and key data elements for receiving, storage, dispatch, returns and recall
• Validate barcode data and print quality using GS1 General Specifications and scanner-readability checks
• Assess supplier and 3PL traceability capability using a structured onboarding and compliance checklist
• Produce a site-level GS1 traceability implementation blueprint with controls, owners and priority actions

Benefits of attending

Target competencies

Who should attend

• Distribution Centre Managers — who need reliable receiving, dispatch and recall controls across warehouse operations
• Supply Chain Managers — who must connect supplier, warehouse, carrier and customer traceability requirements
• Warehouse Operations Managers — who oversee scanning processes, inventory accuracy and exception handling
• Logistics Systems Analysts — who configure WMS, ERP or integration rules for barcode and event data
• Master Data Managers — who govern GTIN, GLN and trading-partner product information
• Quality and Traceability Managers — who must demonstrate lot, serial and shipment traceability during audits or recalls

Requirements and prerequisites

Participants should have working experience of warehouse, distribution, inventory-control, transport or supply chain data processes. They should understand basic concepts such as purchase orders, goods receipt, stock movements, picking, dispatch, SKU or item master records, and batch or lot numbers. Familiarity with a WMS, ERP or barcode-scanning workflow is useful because exercises refer to system transactions and operational exceptions. No prior GS1 membership, barcode-design experience, programming skill, EPCIS implementation experience or specialist label-printing software is required. Participants do not need to bring production data; training examples and templates are provided.

Training methodology

The instructor uses short standards briefings followed by applied distribution exercises. Participants decode GS1-128 examples, compare label layouts against GS1 General Specifications, map warehouse transactions to EPCIS 2.0 events, and investigate a simulated lot-trace and recall case. Small groups develop requirements for a supplier-to-distribution-centre flow, then test them against common exceptions such as relabelling, mixed pallets and returned stock. The final session converts workshop outputs into an individual implementation blueprint with owners, evidence requirements, dependencies and first actions.

Course outline

Day 1: GS1 identification foundations for distribution

• GS1 system architecture across product, party, location and logistics-unit identification
• GTIN allocation rules for trade items, packaging levels and variable-measure products
• GLN use for legal entities, functional locations and physical warehouse locations
• SSCC structure and serialisation rules for pallets and other logistics units
• GS1 key relationships within purchase order, ASN, receipt and dispatch processes
• GS1 General Specifications as the governing source for barcode and data-carrier rules
• Identifier governance, ownership and change-control responsibilities

Workshop: Participants analyse a distribution data set and produce an identifier map showing the correct GTIN, GLN and SSCC use at each process hand-off.

Day 2: Barcode data carriers and logistics labels

• GS1-128 symbol structure, FNC1 use and concatenated element strings
• Application Identifiers for batch, expiry date, serial number, quantity and SSCC
• GS1 DataMatrix selection for item-level identification and constrained label space
• Logistics label zones, human-readable interpretation and mandatory data placement
• Barcode size, quiet zones, contrast and print-quality considerations
• Scanner configuration and parsing rules for variable-length Application Identifiers
• Label verification and common non-conformance diagnosis

Workshop: Participants decode sample barcodes and create a GS1-128 pallet-label specification for a batch-controlled outbound shipment.

Day 3: Traceability event capture with EPCIS

• EPCIS 2.0 purpose, event model and vocabulary for supply chain visibility
• ObjectEvent mapping for receiving, commissioning, decommissioning and observation
• AggregationEvent mapping for pallet build, unpack, cross-dock and de-aggregation activities
• TransformationEvent use for repacking, kitting and product conversion scenarios
• What, when, where and why dimensions of traceability event data
• Critical Tracking Events and Key Data Elements in distribution traceability design
• EPCIS query concepts for shipment verification and recall investigation

Workshop: Participants map a receiving-to-dispatch warehouse flow into an EPCIS event model and produce a Critical Tracking Event and Key Data Element register.

Day 4: Operational controls, data governance and partner compliance

• Master-data alignment between supplier, WMS, ERP, TMS and customer systems
• Advance Ship Notice data and SSCC reconciliation at goods receipt
• Supplier barcode-label requirements and conformance-testing procedures
• 3PL operating agreements for scanning, relabelling, storage and dispatch evidence
• Exception workflows for unreadable labels, unknown GTINs, mixed lots and duplicate SSCCs
• Returns, reverse logistics and product-status traceability controls
• Audit trails, retention rules and recall-response evidence packs

Workshop: Participants conduct a supplier-and-3PL compliance review using a checklist and produce a corrective-action log for identified traceability gaps.

Day 5: Implementation planning and traceability assurance

• Current-state traceability assessment and gap-prioritisation method
• Target-state process design for inbound, inventory, outbound and returns flows
• Requirements writing for WMS, label-management and integration changes
• Traceability test scripts for lot tracing, SSCC genealogy and shipment verification
• Recall simulation design, timing measures and evidence-validation criteria
• Implementation governance, RACI roles and supplier rollout sequencing
• Performance indicators for scan compliance, data accuracy and traceability response time

Workshop: Participants complete and present a GS1 traceability implementation blueprint containing process controls, data requirements, tests, accountable owners and a 90-day action plan.
