Everyone who is engaged in business activity in Norway or on the Norwegian Continental Shelf must have an organisation number. The same applies to businesses that only have employees who work in Norway.
The organisation number identifies legal persons (entities) and, among other things, it is necessary in order to fulfil certain statutory obligations in relation to the authorities, for example the payment of tax withholdings, National Insurance contributions and value added tax. It is not just in connection with fulfilling obligations in relation to the Norwegian authorities that it is important to have an organisation number. For instance, banks and other finance institutions will require an organisation number in connection with the opening of a bank account.
The organisation number must always be included on all the entity’s business documents.
