From January 2, 2021, the National Immigration Agency of the Ministry of the Interior started to replace and issue the new UI No. for foreign nationals in order to provide a friendly living environment for international communities in Taiwan.
The new format of the UI No. matches the ID code used for ROC citizens, so it makes it a lot easier to create bank accounts, book tickets, shop online, and even buy face masks.
This effort to improve the living environment is aimed to encourage overseas friends to live in Taiwan and promote a more bilingual nation.
