ID No. (optional) DEMO

  1. At present, Taiwan’s Uniform Identification (UI) Number format is divided into two formats. The old format consists of 2 English letters plus 8 numerical digits, and the new format consists of 1 English letter plus 9 numerical digits. If you once had an ID number in the old format but have converted to a new UI number, please use your new UI number to apply.
  2. If you are not a Hong Kong or Macao resident, UI No. means ARC number.
