Frequently asked questions

What information will be passed on when checking the company?

The company inquiry will compile the eight-digit number and transmit it to the third-party "Taiwan Company Information" service, and the invoice items or amounts will not be sent together. The third-party results can be checked in the Ministry of Economic Affairs’ Commercial and Industrial Registration Disclosure Information.

What should I do if I cannot find company information?

First confirm that the unified number is the correct eight-digit number; if the screen shows that there is no data, timeout or failure, you can go to the Ministry of Economic Affairs' Commercial and Industrial Registration Publicity Information to check and confirm. The results of third-party inquiries should not be taken directly as proof of the latest registration status.
