Establishments and Branches of a Norwegian Company (Enhetsregisteret)

brreg/sub-units-of-company

Lists the sub-units (underenheter: establishments and branches) registered under one Norwegian main unit, found by that unit's nine-digit organisation number. Returns one page, sorted by organisation number, with each sub-unit's organisation number, name, form, location and postal address, number of employees, NACE activity code, start date and phone, plus the total number of sub-units. Lookup by organisation number only: there is no search by name. A number with no sub-units returns a total of 0. Personal data: for a sole proprietorship the sub-unit name is the proprietor's own name and the record can carry their address and phone. Contains data under the Norwegian Licence for Open Government Data (NLOD) from the Brønnøysund Register Centre, served by Eden Engine; not an official Brønnøysund Register Centre product.
