About the figures

Each industry is a hand-picked group of SN2007 activity codes, chosen because it names something readers recognise. The set is not a complete partition of the register.

Biztrac.no · Data from the Brønnøysund Register Centre and the Norwegian Tax Administration · Last updated 03.10.2026.

These lists show actual registered figures from public sources (the Brønnøysund registers). They are not an assessment of creditworthiness, solidity or suitability as a customer, supplier or investment. Figures are for the most recently reported financial year.
