What is the public register of Tax Numbers?
The TN Register is a public and open government register. It is operated by the Tax Administration. All employees who work at construction sites are registered with their individual Tax Numbers. The mandatory name tag worn by everyone at construction sites must have the Tax Number printed on it.
What can you do in this website?
Check the correctness of registration entries, search names and Tax Numbers to see whether they match. Online searches result in a simple statement on whether he or she is registered. It is not enough to just type the name, or to just type the Tax Number alone. Searches require the input of the first names, last names and Tax Numbers searched. The search result is the answer to the question whether they match, in other words, whether there is a registration or not. No other information (such as the individual's personal identity code) is displayed.
