Setting up a company in Romania involves several steps, and choosing the correct NACE Rev.3 codes is one of the most important. NACE codes define the activities your company will perform and influence the applicable tax regime.
What are NACE Rev.3 codes?
NACE codes are 4-digit numerical codes identifying the type of economic activity carried out by a company. Revision 3 (Rev.3) is the latest update, effective since 2025.
Steps for registering with NACE Rev.3 codes
1. Choose the legal form
Decide between a PFA (Authorized Individual) and an SRL (Limited Liability Company). Each has advantages depending on the nature of your activity.
2. Select the right NACE Rev.3 codes
Choose a main code that best describes your core activity. Add secondary codes for related activities you plan to perform.
- Main code – defines the dominant activity
- Secondary codes – allow business expansion
- No limit on the number of secondary codes
3. Check restrictions
Certain codes require special conditions: licenses, qualifications, or higher minimum capital.
4. Submit the file to ONRC
The complete file is submitted to the National Trade Register Office. Processing typically takes 3-5 business days.
