The expert from Japan, on behalf of the IWVTA Ambassador of GRSP, informed GRSP about IWVTA IWG progress and introduced WP.29-179-08 on the proposed list of UN Regulations applicable to IWVTA Phase 2 (2018 – 2022). The expert from Finland introduced GRSP-66-18 to promote the Database for the Exchange of Type Approval (DETA), on using DETA, and information for competent authorities and manufacturers. GRSP was requested to provide feedback at its May 2020 session. GRSP also noted that WP.29 had encouraged GRs to review the application of the Unique Identifier (UI) and markings, and to provide guidance on how to proceed (ECE/TRANS/WP.29/1149, para. 65) on the basis of:

• Option 1: Use UI and keep the installation marking and the information on the part.
• Option 2: Use UI only for the approval marking and provide open access to the communication document, which would also include the necessary installation marking.
