The DIR3 are three alphanumeric codes necessary to correctly send e-invoices to public administration offices. DIR3 is the “Directory of Organic Units and Registry Offices for the Public Administration.” The information provided by DIR3 corresponds to the accounting office, the managing body and the processing unit of a public administration office. These three codes are mandatory to issue an invoice. 

Below is an image of how they appear on the Docuten invoice form. The “proposing entity” is not mandatory, but is used in some public administration offices.
