Overview
EN 18219:2026 - Digital Product Passport: Unique Identifiers is a European Standard developed by CEN to define the principles, requirements, and guidelines for assigning globally unique product, economic operator, and facility identifiers within digital product passports (DPPs). This standard establishes a universal framework that supports traceability, transparency, and interoperability across supply chains-key pillars for a sustainable, circular economy. It specifies how identifiers should perform at varying levels of specificity (model, batch, or individual item), and adapts to different issuance methods, including agency-based and self-issuing systems.
The document aligns closely with the European Green Deal and the Ecodesign for Sustainable Products Regulation (ESPR), ensuring that digital product passports enable reliable, standardized, and accessible product data throughout the product lifecycle.
Key Topics
- Global Uniqueness: Each identifier must uniquely distinguish an object (product, operator, or facility). No two objects may share the same identifier within its applicable context.
- Persistence: Identifiers are designed to remain consistent and valid for the lifespan of the object, unaffected by organizational or ownership changes.
- Syntax: Defines the structure of identifiers to ensure recognition and processing compatibility, often requiring web-enabled formats (such as URLs or resolvable URIs).
- Semantics: The identifier structure reflects the object’s nature and granularity, allowing accurate reference to models, batches, or items.
- Interoperability: Enables identifiers to function seamlessly across diverse platforms, data carriers, and digital product passport ecosystems.
- Openness: Promotes transparent, publicly accessible identification policies and schemes to foster adoption and integration.
The standard details permissible identification schemes for products (e.g., structured paths, decentralized identifiers, digital object identifiers) and for economic operators and facilities (e.g., Legal Entity Identifier, decentralized and digital object identifiers).
Applications
EN 18219:2026 delivers practical value across multiple domains:
- Supply Chain Traceability: Unique digital identifiers ensure every product and associated entity can be accurately tracked from production to end-of-life, meeting regulatory and consumer expectations for transparency.
- Sustainability Reporting: Integrating persistent and resolvable identifiers into digital product passports supports compliance with sustainability and circular economy requirements.
- Consumer Access: Web-enabled unique product identifiers make it easy for stakeholders-including consumers, retailers, and regulators-to access key product data (such as durability, recyclability, and repair options) via product scanning or online lookups.
- Regulatory Compliance: Supports the requirements of the Ecodesign for Sustainable Products Regulation and other EU policy frameworks by standardizing the identification needed for digital product passport systems.
- Operational Efficiency: Adoption of globally recognized and interoperable schemes facilitates smoother integration with IT systems, reduces duplication, and lowers operational costs for manufacturers and distributors.
Related Standards
EN 18219:2026 harmonizes with international and European standards to ensure consistency and interoperability, including:
- ISO/IEC 15459 (Unique identification for items)
- ISO/IEC 6523 (Identifiers for organizations)
- ISO/IEC 18975 (Encoding and resolving identifiers over HTTP)
- ISO 17442-1 (Legal Entity Identifier)
- ISO 26324 (Digital Object Identifier system)
- EN IEC 61406 (Identification Link for products)
- W3C DID and Verifiable Credentials (Decentralized identifier frameworks)
The document also references guidance and best practices for selection and operation of ID schemes, helping organizations implement identifiers that align with both regulatory and operational needs.
