What do the 4 digits that I sometimes see behind the CE logo on a product mean?
If the conformity assessment shows that a product has to be tested by a Notified Body (NoBo), four digits will be left behind the CE. That number corresponds to the NoBo number. They all have a number and you can easily track on NANDO. There you can also see if the NoBo is authorized to test such products or that it has expired.
