VAT number
The VAT identifier, in the form FI followed by eight digits.
A Finnish VAT number is built from the Business ID: the country code FI followed by the eight digits of the Business ID with the hyphen removed. Business ID 1927400-1 becomes FI19274001.
That the number can be derived does not mean the company is liable for VAT. The Tax Administration enters a business in the VAT register separately, and only that entry makes the number valid. Registration is compulsory once turnover for the financial year passes the statutory threshold, and voluntary below it.
Validity can be checked in the European Commission's VIES system, which answers for the whole EU. Checking the number on a new partner's invoice is a routine step: an invalid one can cause problems when deducting input VAT.
