Norwegian Organisation Number Checker
Check a Norwegian organisasjonsnummer or MVA number and confirm the company in Enhetsregisteret — with its registered name, address and organisation form.
What is a Norwegian organisasjonsnummer?
The organisasjonsnummer (org.nr) is the 9-digit number Brønnøysundregistrene gives every company and business in Norway’s Central Coordinating Register (Enhetsregisteret) — for example 984 851 006 for DNB Bank ASA. Once the business is VAT-registered, the same number followed by MVA is its VAT number.
Norwegian organisation number format
Eight digits and a mod-11 check digit; MVA after it marks a VAT-registered business.
(e-invoices, international)
(mod 11)
suffix
Example: 984 851 006 (DNB Bank ASA). On invoices: 984851006MVA; in e-invoices: NO984851006MVA.
- 9 digits: Often printed in groups of three (984 851 006). Spaces, NO and MVA are not part of the number itself.
- Check digit: Weights 3-2-7-6-5-4-3-2, mod 11, as published by Brønnøysundregistrene. The sample NO123456789MVA fails it.
- MVA suffix: Only VAT-registered businesses may write MVA after the number. Our checker confirms the company exists, not its VAT status.
- Main entities: Each business location (underenhet) also has its own 9-digit number; the checker looks up main entities.
How to check a Norwegian organisation number
- 1 Find the org.nr on the company’s invoice or website — usually printed as “Org.nr 984 851 006 MVA”.
- 2 Enter it above, with or without NO, spaces or MVA. The checker confirms the company in Enhetsregisteret.
- 3 Compare the returned name, address and organisation form with the business you are dealing with.

Frequently Asked Questions
Is the Norwegian VAT number the same as the organisation number?
Yes. Once a business is in the VAT Register, its VAT number is its 9-digit organisation number, written with MVA after it on invoices — for example 984 851 006 MVA for DNB Bank ASA.
How do I check whether a Norwegian company is VAT-registered?
VAT registration is shown in the company’s entry in Enhetsregisteret at Brønnøysundregistrene, under “Særlige opplysninger”. A valid organisation number on its own does not mean the business is registered for VAT.
Can I check a Norwegian VAT number in VIES?
No. Norway is not in the EU, so the EU VIES system does not cover Norwegian numbers. Norwegian VAT status is published through Enhetsregisteret.
Do I write “NO” in front of a Norwegian VAT number?
Norwegian invoice rules require the organisation number followed by MVA (984851006MVA). The NO prefix is not in Norwegian law, but it is required in Peppol/EHF e-invoices (NO984851006MVA) and is common internationally.
How is the organisation number check digit calculated?
Multiply the first eight digits by 3, 2, 7, 6, 5, 4, 3 and 2, add the results and divide by 11. The check digit is 11 minus the remainder; a remainder of 0 gives 0, and a remainder of 1 means the number is not valid.
When must a business in Norway register for MVA?
Once its VAT-able sales exceed NOK 50,000 (excluding VAT) within 12 months — NOK 140,000 for charitable and non-profit organisations. It cannot charge VAT before it is registered.
