Digital product passport - Unique identifiers

Scope

This document aims to define requirements for unique identifiers used to identify products, facilities and economic operators .
The standard covers aspects such as ensuring uniqueness, syntax -related requirements, and semantic-related requirements for identifiers. It allows for both centralized and decentralized identifier systems.
Additionally, the standard ensures that the unique product identifier accommodates three granularity levels: model, batch, or item, as required by the European Single Product Passport Regulation (ESPR).
To promote interoperability, reduce costs for businesses, and align with existing European regulations and initiatives, the standard takes into account the various types of identifiers already used in other legislations. Relevant existing standards are considered during the development to maintain consistency and coherence with industry practices and regulations
