Overview

EN ISO 17419:2025 - Intelligent transport systems: Globally unique identification defines a consistent, global approach to addressing and identifying ITS components. It specifies globally unique addresses and ITS‑S object identifiers used both inside and outside ITS stations for management, classification, registration and communications. The standard also provides an organizational framework for registration, high‑level management procedures, and ASN.1 modules for identifiers and a C‑ITS data dictionary. It is based on the ITS station architecture (ISO 21217) and treats an ITS station as a bounded secured managed domain (BSMD).

Key topics and technical requirements

• Globally unique identifiers and addresses: Rules and structures for ITS‑S object identifiers used for device, object and application identification across domains.
• Classification, registration and management: How identifiers and technical parameters are applied to classify ITS applications and application classes, and to maintain registries.
• Use in the communication stack: Guidance on how ITS‑S identifiers and addresses are embedded and used across ITS communication protocol layers.
• Organizational framework (GCMA): A governance model for registration and lifecycle management of ITS‑S objects and registries.
• Management procedures: High‑level functional procedures for registration, certification and operational management of identifiers and ITS stations.
• ASN.1 modules: Standardized Abstract Syntax Notation One (ASN.1) modules specified for identifiers, addresses, registry records and a C‑ITS data dictionary with ASN.1 type definitions.
• Security and PKI considerations: The document references ITS PKI architecture and management implications (e.g., certification of ITS‑S equipment) as part of holistic identifier management.
• Conformance with ITS station model: Aligns with ISO 21217 ITS station architecture (BSMD model).

Practical applications

• Ensures interoperability across C‑ITS deployments by providing unique, globally-recognized identifiers for devices, applications and messages.
• Enables centralized and decentralized registries for ITS services, improving service discovery, lifecycle management and governance.
• Supports secure communications and certification workflows by integrating identifiers with PKI and certificate management.
• Useful for software developers, device manufacturers, system integrators, road authorities, C‑ITS service providers, certification bodies and registry operators implementing or operating ITS infrastructures.

Who should use this standard

• ITS system architects and integrators
• Automotive and roadside equipment manufacturers
• C‑ITS service operators and platform providers
• National/regional transport authorities and registry administrators
• Security architects designing ITS PKI and certificate flows
