Economic activities are classified by their codification, by fields and subfields of activity, and within the subfields, by specific activities. The main domains are coded with 2 numbers, the subdomains with 3 numbers, and the activities themselves, each with a 4-digit code. The classification of activities in the national economy of Romania – CAEN was updated in 2007 in compliance with the provisions of the European Commission Regulation no. 1,893/2006 amending the Regulation of the Council of the European Economic Community no. 3.037/90 regarding the Nomenclature of Activities from the European Community – NACE Rev. 2.
When registering an economic structure (commercial company, authorized natural person) in the Trade Register, it is necessary to indicate the coded activities with 4 digits.
It is useful to know that the activities coded with 4 digits are generic names that include de facto or by assimilation several specific activities. That is why it is useful to consult the CAEN Guideline, taken from the website of the European Commission (https://ec.europa.eu) pag 95 – 315:
