The Finnish national LVI-numbers are unique 7-digit identification numbers for the HVAC-products sold on the Finnish market. With these LVI-numbers the HVAC-products are identified in the whole supply chain, from the planning process to the end user.
LVI-INFO maintains the Finnish national LVI-number register. To apply for a LVI-number, you must first register as a customer of LVI-INFO.fi (see page: Become a customer).
