Submit it at the NHI counter 22, South Annex 2nd floor, or send it by post with a copy of an identity document. Citizen offices do not handle this application. Members of another health insurance apply to their current insurer instead. The form and a filling example are attached.

Where to file
Citizen offices do not handle this application, so file at the NHI counter or by post.
Members of another health insurance apply to the insurer they are enrolled with.
By post
- Send the form with a copy of an identity document.
- If there is no single identity document that verifies identity, you must visit the office.

Certificates after cancellation
The eligibility certificate and the elderly recipient certificate are sent about five office days after the ward receives the application, except when documents are incomplete or year-end and New Year holidays fall in the period. They are not sent to people who hold certificates valid until 31 July 2026.
