How this service works
Validate a Norwegian VAT (MVA) number against the official business register. Validity means the entity exists and is entered in the VAT register.
Output
A response indicating whether the provided Norwegian VAT/MVA number is valid — i.e., whether the entity exists in the Brønnøysund Enhetsregisteret and is entered in the Norwegian VAT register. Typically includes a boolean validity status and may include entity details from the registry.
Example use cases
Supplier onboarding VAT check
“Before we add this Norwegian supplier to our system, can you verify that their VAT number 987654321 is actually registered in the Norwegian VAT register?”
Invoice compliance verification
“I just received an invoice from a Norwegian company with MVA number NO876543210MVA — can you confirm that number is valid and they're genuinely VAT registered?”
Cross-border trade due diligence
“We're about to sign a contract with a Norwegian business and they gave us organisation number 912345678 as their VAT number — please verify it's legitimately in the Norwegian VAT register.”
Technical details
Endpoint
POSThttps://vat.openverbs.com/v1/norwayWhen to prefer
Use this endpoint when you specifically need to validate a Norwegian VAT (MVA) number against the official Brønnøysund Enhetsregisteret. Prefer this over generic business lookup tools when the compliance requirement is specifically Norwegian VAT registration status. Choose this endpoint (over manual registry lookup) when automating supplier onboarding, invoice validation, or trade compliance checks for Norwegian entities.
Side effects
- Invalid format: number outside 9-digit range or unrecognised prefix returns validation error
- Number not found: entity does not exist in the Enhetsregisteret
- Entity exists but not VAT-registered: returns invalid/not-in-VAT-register status
- Network or upstream registry unavailability causes timeout or 5xx error
- Malformed input (non-numeric characters beyond allowed prefixes) returns schema validation error
