Affixing the CE mark and when the NANDO number of a Notified Body must be added

Modified on Wed, 28 Aug at 1:06 PM

The European Union requires the CE mark to be visible, legible and indelible. To ensure readability, the CE marking must be no smaller than 5mm (unless otherwise specified in relevant directive(s), regulation(s) or product requirements). It must consist of the initials “CE” and have the dimensions indicated below:

If the CE marking is enlarged or reduced, the proportions indicated above must remain unchanged. When it is not possible to affix the CE mark to the product itself, the CE marking must be affixed on the product packaging or the official accompanying documents.


The CE mark is part of the New Legislative Framework. Under this framework it is only allowed to place the NoBo number next to the CE mark if the Notified Body is involved in the production control, these are Modules such as Module D or Module A1. 


If you have a certificate from us you can only place the NoBo number on your CE mark if this certificate has the Modules A1/D or D1. As a matter of fact if you have such certifcates you must affix the number. 


What is allowed is to place the NoBo name/logo on the certificate or to indicate 'Product was certified by Global Network Group TIC (or any brand name) (NANDO 2832)', but the number next to the CE mark is a specific indication that is reserved for specific Modules. 



See also below some explanation from the European Commission on this topic: 


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.
