NAF 2025: Your new classification of activities

On 1 January 2026, the French classification of activities – NAF 2025 – will come into effect in the Principality of Monaco, replacing the current NAF 2008.

Monaco Statistics will therefore update your NAF code and your Statistical Identification Number (NIS) and will send them to you by post in due course.

Monaco Statistics will communicate your new NIS to the relevant departments of the Prince's Government and to the Caisses Sociales de Monaco. We would like to assure you that this change will not have any impact. Therefore, there will be no need for you to take any action with these entities.

Should you have any queries, please contact Monaco Statistics by email at contact or by telephone on 98 98 98 88.
