What is a GTIN?
The GTIN is the GS1 identification key for trade items and services. It lets a product be referenced consistently across retail, logistics, marketplaces and data platforms.
In product passport work, the GTIN is often the bridge between existing barcode infrastructure and a new DPP data model. It does not automatically replace serial numbers, batch identifiers or regulatory data fields.
What role does the GTIN play in DPP?
ESPR requires a persistent unique product identifier. A GTIN can serve that role for product models or trade items when the relevant delegated act and data architecture support that level of identity.
When data varies by batch or individual item, the data model needs another level of granularity. A battery passport, repair event or recall may require a different identifier level than a product family.
- GTIN: identity for the trade item or product model.
- Batch or lot: shared data for a production group.
- Serial number: individual data for one product or battery.
What should teams prepare?
Teams should check which products already have clean GTINs, where variants are managed ambiguously and which system is the source of truth for product identity. DPP projects often fail because item and variant master data is inconsistent, not because the QR code is hard.
Nulara uses GTINs as part of product identity and connects them with sources, evidence, approvals and access levels. Trade systems stay compatible while the product passport exposes regulatory data in structured form.
