The Ministry of Finance provides a description of the API programming interface of the List of VAT taxpayers, i.e. the list of registered, unregistered entities as well as deleted and restored to the VAT register. The API programming interface is currently in the internal testing phase, therefore it may still change. The API specification and test environment address will be available until August 22, 2019.

The technical description of connecting to the API can be found on the website of the National Tax Administration

In the next stage (the date will be announced until August 31, 2019), it is planned to publish a text file for download by users, which contains a full list of tax identification numbers, allowing for mass verification of transactions in financial and accounting systems.
