The company details (name, address, postal code, plot numbers…) mentioned in the application form for a CEP application (holders, manufacturing sites etc.) are reported on the CEPs. This information must therefore be accurately declared. Particular attention should be paid when applying for a revision or renewal as differences are sometimes observed between the details provided in the original application and those provided in the request for revision or renewal but these differences are not explicitly declared as changes. In order to ensure a rapid treatment of applications it has been decided to consider such changes to company details only when these have been appropriately declared as a change in both the cover letter and in the comparative table for the application.
