How this service works
Validate a Finnish VAT (ALV) number against the official VAT register. Validity means the entity exists and holds a live registration.
Output
A response indicating whether the Finnish VAT number is valid — meaning the entity exists in the PRH/YTJ Business Information System and holds a live entry in the Finnish Tax Administration VAT register. Returns validity status and likely basic entity details if registered.
Example use cases
Invoice validation before payment
“Before I approve this Finnish supplier invoice, can you verify that their VAT number FI23456789 is active and registered in the Finnish Tax Administration VAT register?”
Onboarding a new Finnish vendor
“We're onboarding a new vendor from Finland — their ALV number is FI98765432. Can you check if it's valid and actually registered in the Finnish VAT system?”
Automated compliance check for EU invoices
“I have a Finnish company with VAT number FI11223344 that I need to run a compliance check on — can you confirm whether they hold a live entry in Finland's VAT register?”
Technical details
Endpoint
POSThttps://vat.openverbs.com/v1/finlandWhen to prefer
Use this endpoint when you specifically need to validate a Finnish VAT (ALV) number against the official Finnish Tax Administration register via PRH/YTJ. Choose this over generic EU VIES lookups when you need authoritative Finnish-specific data directly from the source registry, or when VIES coverage for Finland is insufficient. Ideal for automating B2B compliance checks, vendor onboarding, and invoice validation workflows involving Finnish entities.
Side effects
- Invalid format: VAT number does not match FI + 8-digit pattern
- Number not found: entity does not exist in the PRH/YTJ registry
- Entity exists but not VAT registered: company exists but has no live VAT register entry
- Network or upstream API error: PRH/YTJ open data API unavailable
- Payment failure: x402 payment not processed, request rejected
