Where do I fill in my previous Taiwan ARC number?
Please follow the steps below or the attached photo to fill in your ARC number. Case Status Check → The List of Supplemental Documents → View → Modify → Resident → ID No. (optional)
- At present, Taiwan’s Uniform Identification (UI) Number format is divided into two format. The old format composes 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.
- If you are not a Hong Kong or Macao resident, UI No. means ARC number.
