An unverified supplier MVA number puts your input VAT deductions at risk and can trigger Skatteetaten enforcement fines. Here is the verdict: you can verify any Norwegian Value Added Tax (VAT) number free in under a minute. Search the entity at the Brønnøysund Register Centre, then confirm it is registered in the VAT Register. Norway is not in the European Union (EU), so VIES (the VAT Information Exchange System) does not work for Norwegian numbers.
You have three routes. Search manually at brreg.no, call the free open API (application programming interface) of the Central Coordinating Register for Legal Entities (Enhetsregisteret), or run automated bulk validation. All three read the same government data.
| Verification route | Cost | Best for | Source |
|---|---|---|---|
| Manual search on brreg.no | Free | One-off supplier checks | Brønnøysund Register Centre |
| Open Enhetsregisteret API | Free, no key | Developers, spot automation | Brønnøysund Register Centre |
| Bulk validation (CSV or API) | Varies | AP teams with many suppliers | Commenda |
What Is a Norwegian VAT Number?
A Norwegian VAT number is the 9-digit organisasjonsnummer (organisation number) followed by the suffix MVA (Merverdiavgift, the Norwegian term for VAT). Only entities entered in the VAT Register (Merverdiavgiftsregisteret) hold one. Every registered entity has an organisation number, but an organisation number alone does not prove VAT registration.
Verification is two checks: the entity exists, and it sits in the VAT Register. Skatteetaten (the Norwegian Tax Administration) sets the VAT rules. The Brønnøysund Register Centre operates the registers, including Enhetsregisteret, which holds the organisation number for every Norwegian legal entity.
What Is the Norwegian VAT Number Format?
The domestic format is nine digits, a space, then MVA, for example 123456789 MVA. The NO prefix (NO123456789MVA) appears only on international and EU-facing documents. It is not part of the domestic number. Even with the NO prefix, the number cannot be validated in VIES, because Norway sits outside the EU.
How Does the MOD 11 Check Digit Work?
The ninth digit is a MOD 11 control digit computed from the first eight. Multiply the first eight digits by the weights 3, 2, 7, 6, 5, 4, 3, 2, sum the products, and divide by 11. The check digit is 11 minus the remainder. A required check digit of 10 means the number is invalid, per the Brønnøysund Register Centre organisation number rules.
Worked example: take the first eight digits 12345678. The weighted sum is 138. Dividing 138 by 11 leaves a remainder of 6. The check digit is 11 minus 6, which is 5. The valid number is 123456785. This lets you screen a number offline before any lookup.
How Do You Verify a Norwegian VAT Number Online?
Three routes verify a Norwegian VAT number. Run a free manual search at brreg.no, call the free open Enhetsregisteret API, or use automated bulk validation. All three read the same authoritative government data. Each confirms both that the entity exists and that it appears in the VAT Register.
How Do You Check a VAT Number on brreg.no?
Go to brreg.no/en, search by organisation number or company name, and click “Søk” (Search). On the results page, look under “Særlige opplysninger” (special information) for “Registrert i Merverdiavgiftsregisteret” (registered in the VAT Register). An entity showing in search results is not enough. That VAT Register indicator is the deciding check.
- Go to the Brønnøysund Register Centre at brreg.no/en.
- Enter the 9-digit organisation number or the company name.
- Click “Søk” (Search).
- Confirm the entity name and address match your supplier.
- Under “Særlige opplysninger”, check for “Registrert i Merverdiavgiftsregisteret”.
- Record the date and result for your audit trail.
Is There a Free API to Verify Norwegian VAT Numbers?
Yes. The Brønnøysund Register Centre runs a free, open API at data.brreg.no/enhetsregisteret/api/enheter/{orgnr}, with no key required. It returns JSON (JavaScript Object Notation), including the boolean registrertIMvaregisteret flag that confirms VAT registration, per the Enhetsregisteret open data documentation.
Search is real-time, and the full datasets refresh every 24 hours (Brønnøysund Register Centre). The response also includes the registration date. Enhetsregisteret data is public open data, so these lookups transmit no confidential information.
How Do You Bulk-Verify Supplier VAT Numbers?
Manual checks do not scale for accounts payable (AP) teams with hundreds of suppliers. Automated validation via CSV (comma-separated values) upload or API checks every supplier number against the register in one pass. Commenda’s tax ID verification validates IDs across countries. Vatstack and VATapp also offer Norway validation.
Why Should You Verify a Norwegian VAT Number Before Paying an Invoice?
Verification confirms the supplier is genuinely VAT-registered. That protects your input VAT deductions and guards against fraudulent invoices charging MVA the seller never remits to Skatteetaten. Re-verify before onboarding a new supplier and before any large payment. A supplier can deregister or change its details at any time.
What Are the Consequences of Using an Invalid Norwegian VAT Number?
The main risks are denied input VAT deductions, enforcement fines, and blocked refund claims. Skatteetaten charges a daily coercive fine (tvangsmulkt) for missing information deadlines and additional tax (tilleggsskatt) for incorrect reporting. An invalid supplier number can disallow the input VAT you claimed on that invoice, which is the most concrete business risk.
What Is the Norwegian VAT Registration Threshold?
A business must register once taxable turnover exceeds NOK 50,000 (Norwegian krone) in a rolling 12-month period, per Skatteetaten. The same threshold applies to domestic and foreign businesses. Charitable and non-profit organisations register at NOK 140,000. The table routes the enumerable threshold and filing rules, each with its named source.
| Rule | Amount | Notes | Source |
|---|---|---|---|
| Standard registration threshold | NOK 50,000 / rolling 12 months | Mandatory; interest accrues if you register late | Skatteetaten |
| Charitable and non-profit organisations | NOK 140,000 / 12 months | Higher threshold for benevolent bodies | Skatteetaten |
| Pre-registration (forhåndsregistrering) | NOK 250,000 incl. VAT | Qualifying purchases must link to future taxable sales | Skatteetaten guidelines |
| Annual VAT return eligibility | Turnover under NOK 1,000,000 / year | Apply 10 Dec–1 Feb; return due 10 March | Skatteetaten |
| Sports-event admission services | NOK 3,000,000 | Top men’s football and ice hockey revert to NOK 50,000 | Norwegian VAT Act |
The rolling window is not the calendar year. It may run from February to January, or August to July (Skatteetaten). Every registered enterprise must file a VAT return each period, even when turnover is NOK 0 (Skatteetaten).
What Are the Norwegian VAT Rates in 2026?
Norway applies a 25% standard rate, a 15% reduced rate, and a 12% reduced rate, per Skatteetaten. Exports and newspapers are zero-rated. The table lists each 2026 rate and what it covers.
| Rate | Applies to | Source |
|---|---|---|
| 25% (standard) | Most goods and services | Skatteetaten |
| 15% (reduced) | Foodstuffs; water and wastewater services | Skatteetaten |
| 12% (reduced) | Passenger transport, hotel and room letting, cinema, broadcasting, cultural and sporting admission | Skatteetaten |
| 0% (zero-rated) | Exports, newspapers, certain books | Skatteetaten |
The 15% band expanded on 1 July 2025, when water and wastewater services moved from 25% to 15% (Skatteetaten). Electric vehicles (EVs) are no longer fully exempt. Since 1 January 2026, VAT applies to the portion of an EV’s price above NOK 300,000, down from NOK 500,000 set in 2023, per the Storting’s 2026 budget resolution.
Why Does a Norwegian VAT Number Show as Invalid?
Most failures are formatting errors. Common causes are the wrong digit count, a missing MVA suffix, confusion with Nordic country codes (SE, DK, FI), stray spaces or hyphens, a failed MOD 11 check digit, or an entity that simply is not in the VAT Register. The table maps each cause to a fix.
| Result | Likely cause | Fix |
|---|---|---|
| Not recognised or invalid | Typo or wrong digit count | Re-check for exactly 9 digits; validate the MOD 11 check digit |
| Entity found, no VAT status | Entity exists but is not in the VAT Register | Confirm “Registrert i Merverdiavgiftsregisteret” on the results page |
| No record found | Wrong number, or Nordic country-code confusion (SE, DK, FI) | Remove any NO prefix and re-search the 9-digit number on brreg.no |
| Details mismatch | Number belongs to a different entity | Confirm the registered name and address match your supplier |
| Search unavailable | Temporary maintenance | Retry, or query the open Enhetsregisteret API |
How Does Norwegian VAT Compliance Work for Foreign Businesses?
The NOK 50,000 threshold applies regardless of where the business is established. A foreign business with no place of business in Norway registers in the VAT Register and may need a fiscal representative, depending on its home country. Businesses in some European Economic Area (EEA) countries can register directly. VAT cannot be charged before registration (Skatteetaten).
If your business must register, Commenda’s guide to Norwegian VAT registration for foreign companies and its fiscal representation service cover the steps. Low-value e-commerce sellers may use the simplified VOEC (VAT On E-Commerce) scheme. If you also trade with EU customers, note that EU VAT numbers are validated through VIES, a system Norway sits outside; see Commenda on EU VAT number validation.
