Legal organisation number (declarant) and organisation number for enterprises
Which organisation numbers should you use in the a-melding?
Use two numbers to identify the party for which you are submitting the a-melding
In the a-melding, you identify the entity for whom you’re submitting the a-melding by stating the legal organisation number.
If you have employees, you must also state the organisation number for the sub-entity/enterprise, also called business number.
If you only state the type of employment for the enterprise as pension or work without employment, or you do not state the employment at all, you can state the legal organisation number when specifying the enterprise level in the a-melding.
Legal organisation number
State the legal organisation number of the main entity in order to identify the party for which you are submitting the a-melding. This also applies to sole proprietorships.
All enterprises and associations that register in the Register of Legal Entities are assigned a legal organisation number. The entity that is identified by the legal organisation number is known as the main entity. The main entity is the declarant in the a-melding.
Don’t have a legal organisation number? See brreg.no and altinn.no for more information and application form.
Private individuals must use their national identity number
If you submit an a-melding as a private individual, you must use your national identity number in order to identify the declarant.
Organisation number for enterprises (enterprise number)
State the organisation number for the enterprise and link the employees to the enterprise they work for.
According to the Register of Legal Entities an enterprise is referred to as an enterprise, sub-entity or business.
Everyone who operates commercially and/or has employees, must have at least one sub-entity/enterprise, identified by an organisation number for the sub-entity/enterprise. The sub-entity/enterprise is not independent. It must always be linked to a main entity. Under a main entity, there can be one or more sub-entities/enterprises.
Make sure that the registration in the Register of Legal Entities is correct and report according to the same structure in the a-melding. Complete the registration in the Register of Legal Entities before you submit an a-melding.
Don't have an organisation number for the enterprise? See brreg.no and altinn.no for more information and an application form.
How to find the organisation number for your enterprise
Most people engaged in business activity are assigned both an organisation number for the main entity and for the sub-entity/enterprise. On the website for the Brønnøysund Register Centre (www.brreg.no) you can find the organisation number for your sub-entity/enterprise. Enter your legal organisation number in the field Find enterprise/company. At the bottom of the next page (the search result), you’ll find a link to the page which shows the enterprises registered under the legal entity.
Not yet been assigned an organisation number for enterprise
If you've applied for an organisation number for the enterprise in the Register of Legal Entities, and you've not received it by the deadline for submitting the a-melding, you must delay the submission until you've been assigned the organisation number.
Once you have received an organisation number for the enterprise, you must use this number instead.
Example with one enterprise
A hair salon that intends to run a business in Bodø has registered in the Register of Legal Entities. It has been assigned a legal organisation number and an organisation number for the enterprise in Bodø.
The salon specifies the legal organisation number in order to identify the declarant in the a-melding.
It also states the organisation number for the enterprise in Bodø and links information concerning the employees to this number.
Example with several enterprises
A plumbing firm that intends to run a business in both Oslo and Hamar has registered in the Register of Legal Entities. The firm has been assigned a legal organisation number and two organisation numbers for enterprises, one for Oslo and one for Hamar.
The plumbing firm specifies the legal organisation number in order to identify the declarant when it submits a-meldings for Oslo and Hamar.
It also states the organisation number for the enterprise in Oslo and links information concerning the employees in Oslo to this number.
Correspondingly, it also states the organisation number for the enterprise in Hamar and links information concerning the employees in Hamar to this number.
The firm reports information for both enterprises in the same a-melding (recommended). It can also report information for the enterprise in Oslo in one a-melding and information for the enterprise in Hamar in another a-melding.
Organisation number and employment information in the event of merger, divestment, etc.

Errors concerning legal organisation number
If you have specified the wrong legal organisation number but not received an error message concerning this in the feedback (A03), you must delete all the information that you have submitted for this number.
You do this by submitting an empty replacement a-melding. You must also submit the information under the correct legal organisation number.
Example use of an incorrect organisation number
When she submitted an a-melding, Kari mistakenly used her own national identity number instead of a legal organisation number.
To correct the error, Kari first submits an empty a-melding under her national identity number in order to replace the a-melding that she submitted with the wrong number.
She then submits a new a-melding with the legal organisation number of the main entity for which she is reporting.
| Empty a-melding | |
| Declarant | National identity number |
| Message ID | 2 |
| Replaces message ID | 1 |
No other information.
| New a-melding | |
| Declarant | Legal organisation number |
| Message ID | 1 |
It also enters the other obligatory information.
Error concerning organisation number for enterprises
If you have specified an incorrect organisation number for an enterprise and not received an error message concerning this in the feedback (A03), you will have to move the employee to the correct number.
To correct the error, you must first submit an empty a-melding with the organisation number for the enterprise that is incorrect. You then submit a new a-melding with the correct legal organisation number and organisation number for the enterprise.
If you use a payroll system, check with your system supplier if you are not sure how to make corrections in your system.
What do we use the information for
All information in the a-melding is linked to a legal organisation number (or an organisation number for organisational link). This is used when information in the a-melding is distributed to NAV, Statistics Norway and the Norwegian Tax Administration.
Information on organisation number for enterprises is transferred to the Aa Register together with employment information. The Aa Register contains an overview of the employees of each individual enterprise.
Public authorities such as NAV, Statistics Norway, the Norwegian Labour Inspection Authority and the police agency use information from the Aa Register to fulfil their remit and perform checks.
Applicable regulations
These regulations are only available in Norwegian.
