§4.5.1.5 Affixing CE marking together with the identification number of the notified body

Where a notified body is involved in the production control phase according to the applicable Union harmonisation legislation, its identification number must follow the CE marking. The manufacturer or the authorised representative affixes the identification number if the legislation so requires, under the responsibility of the notified body. A notified body may be involved in the production phase, depending on the conformity assessment procedures applied. The CE marking must be followed by the identification number of the notified body only if it is involved in the production phase. Thus, the identification number of a notified body involved in conformity assessment in the design phase according to module B does not follow the CE marking. Sometimes several notified bodies are involved in the production phase, which is possible where more than one Union harmonisation text is applicable. In these situations several identification numbers follow the CE marking. Thus, if the CE marking appears on products without an identification number, this means that: — either no notified body intervened in the design or production phase (module A); — or upon manufacturer’s choice the in-house accredited body intervened in the production phase (modules A1, A2); — or a notified body intervened in the design phase (module B) but no notified body intervened in the production phase (module C following module B); — or a notified body intervened in the design phase (module B) and upon manufacturer’s choice the in-house accredited body intervened in the production phase (modules C1, C2 following module B). If however the CE marking appears on products with an identification number (238), this means that: — either upon manufacturer’s choice a notified body intervened in the production phase (modules A1, A2); — or a notified body intervened in the design phase (module B) and upon manufacturer’s choice a notified body (not necessarily the same one but the one whose identification number appears) intervened in the production phase (modules C1, C2 following module B); — or a notified body intervened in the design phase (module B) and a notified body (not necessarily the same one but the one whose identification number appears) intervened in the production phase (modules C1, C2, D, E, F following module B); — or a notified body intervened in the design and production phase (modules D1, E1, F1, G1 H, H1). The CE marking and the identification number of the notified body do not necessarily have to be affixed within the Union. They may be affixed in a third country, for example if the product is manufactured there and the notified body carried out conformity assessment in that country in line with the relevant Union harmonisation legislation. The CE marking and the identification number can also be affixed separately, as long as they remain combined.
