Get to know the API White List for business, without limits, able to check up to 15,000 tax identification numbers in an hour

The White List Register (official name: Biała Lista Wykaz Podatników VAT) contains data on both registered and unregistered Polish taxpayers, as well as those deleted and restored to the list. Importantly, proper verification of the VAT contractor from Poland cannot be done without this source, although the official government API White List limits companies to a 300 queries per day. This restriction exposes large organizations carrying out thousands of transactions, to significant costs in the form of loss of the right to deduct 23% VAT and imposing a number of penalties.

Eliminate the risk of losing the right to deduct VAT without significant automation costs. The Transparent Data’s API White List created for business allows you to verify data from the List of VAT Taxpayers of Poland quickly and without limits. Thanks to this solution, you can check up to 15,000 companies in an hour. High SLA of 99% and full data up-to-dateness are promises that we fulfill in practice.
