3. Issuing Authority: NIA Service Centers in all special municipalities, counties and cities.

4. Replacement Method and Required Documents: (Please see Appendix 1 and Appendix 2).

5. Other Matters for Attention:
(1) Regarding the change from original to new UI No.’s, the principle is to adopt a simultaneous replacement mechanism whereby applications are variously processed according to existing rules and applicable fees, and upon an application being approved, the NIA simultaneously assigns a new UI No. to the applicant. Examples are as follows:
a. Example 1: Xiaomei is a person of the Mainland Area whom a transnational corporation has internally transferred to Taiwan. To apply for extension of her Entry & Exit Permit period of stay, she should follow the rules and fee payment set out in the Instructions for Online Applications by People of the Mainland Area to Come to Taiwan to Engage in Business Activities. Upon approval of her application and fulfillment of fee payment, she will simultaneously be assigned a new UI No. in place of her old one.
b. Example 2: Lee is a foreign national residing in Taiwan. To extend her ARC, she should follow the rules and fee payment set out in the Instructions on Submission of Documents by Foreign Nationals Applying for an Alien Resident Certificate, or for Extension or Reissuance Thereof, or for Change of Reason for Residence. Upon approval of her application, she will simultaneously be assigned a new UI No. in place of her old one.
c. Example 3: Lee is a foreign national residing in Taiwan. To proactively change to the new UI No. before the expiration of her ARC, and at the same time change the address recorded on her ARC, she should follow the rules and fee payment set out in How to Apply for Change of Registration of a Foreign National (Migrant Worker). Upon approval of her application, she will simultaneously be assigned a new UI No. in place of her old one.
d. Example 4: Lee is a foreign national residing in Taiwan. To simply apply to change to the new UI No. before the expiration of her ARC, she should follow the document requirements and fees set out in these Instructions.
(2) For those simply applying to change to the new UI No., the original ARC validity period will not be changed.
(3) The original UI No. will stay usable until December 31, 2030, and will cease to be usable as of January 1, 2031.
(4) After an original UI No. is replaced by a new UI No., the original UI No. will be recorded on the back of or in an annotation to the certificate, for provision of comparison.
(5) If you wish to confirm whether a new UI No. has been assigned, you can check this on the “NIA UI No. History Query” webpage.
