Check a Bank Account Against the Polish VAT Register (Biała Lista VAT)

plvatwhitelist/check-account

Whether a 26-digit bank account is registered for a Polish taxpayer's NIP on a given date: the answer is TAK (assigned) or NIE (not assigned). Use it before paying a Polish supplier. A malformed NIP, account or date is refused as invalid input. Data from the Polish Ministry of Finance, passed through unmodified and served by Eden Engine; not an official product.
