The simplification of approval marks and the access to the data in the database require that for each product a unique identifier is available. Such an identifier shall be present on the product and on the first page as well. The unique identifier on a product shall be recognisable as such. The chairman and secretary present a draft model for the unique identifier which is based a symbol derived from the truncated approval mark of Annex 3 to Regulation 37 and which is complemented by a unique number which is generated by the application software. The draft will be forwarded to WP.29 for adoption.
