1 Scope

GB/T 47001-2025 is the Chinese national standard covering the cryptographic identity of a vehicle - how a car proves to the infrastructure, to other vehicles and to its manufacturer's cloud that it is the vehicle it claims to be, with the certificates, their lifecycle and the privacy problem of an identity that can also be used to track. First edition, under the Ministry of Public Security, with the traffic facility identity standard GB/T 46999-2025. It was issued on 31 December 2025 and has been in force since 1 July 2026, as a first edition. The document is under the responsibility of the Ministry of Public Security. This page is published from the official record of the 2025 edition; the clause text of a standard this recent is not yet in circulation, and the figures, limits and tables it contains are those of the document itself, delivered in full with the English translation.

This document specifies the requirements for digital identity encoding, carrier and authentication of intelligent and connected vehicles, and describes the corresponding test methods. This document applies to the design of digital identity authentication processes and the development and testing of the carrier of intelligent and connected vehicles.
