Polish VAT whitelist check (official Ministry of Finance register). Verifies a company's VAT status by NIP and — uniquely — whether a given bank account number (NRB) is registered to that company in the tax register: the standard Polish invoice-fraud check before paying a supplier. Returns VAT status, REGON/KRS, address, registered-account count and the official consultation confirmation id (request_id). Companies only.Overview
